Visit the [Releases page](https://github.com/tinode/chat/releases/), choose the latest or otherwise the most suitable release. From the list of binaries download the one for your database (supported: MySQL, PostgreSQL, MongoDB, RethinkDB) and platform (Linux ARM or Intel, Windows, Mac ARM or Intel). Once the binary is downloaded, unpack it to a directory of your choosing, `cd` to that directory. + +2. Make sure your database is running. Make sure it's configured to accept connections from `localhost`. In case of MySQL, Tinode will try to connect as `root` without the password. In case of PostgreSQL, Tinode will try connect as `postgres` with the password `postgres`. See notes below (_Building from Source_, section 4) on how to configure Tinode to use a different user or a password. MySQL 5.7 or above is required (use InnoDB, not MyISAM storage engine). MySQL 5.6 or below **will not work**, use of MyISAM **will cause problems**. PostgreSQL 13 or above is required. PostgreSQL 12 or below **will not work**. MongoDB 4.4 or above is required. MongoDB 4.2 and below **will not work**. + +3. Run the database initializer `init-db` (or `init-db.exe` on Windows): + ``` + ./init-db -data=data.json + ``` + +4. Run the `tinode` (or `tinode.exe` on Windows) server. It will work without any parameters. + ``` + ./tinode + ``` + +5. Test your installation by pointing your browser to http://localhost:6060/ + + +## Docker + +See [instructions](./docker/README.md) + + +## Building from Source + +1. Install [Go environment](https://golang.org/doc/install). The installation instructions below are for Go 1.18 and newer. Building with the latest Go environment is recommended. + +2. OPTIONAL only if you intend to modify the code: Install [protobuf](https://developers.google.com/protocol-buffers/) and [gRPC](https://grpc.io/docs/languages/go/quickstart/) including [code generator](https://developers.google.com/protocol-buffers/docs/reference/go-generated) for Go. + +3. Make sure one of the following databases is installed and running: + * MySQL 5.7 or above configured with `InnoDB` engine (8.x preferred).

Open `tinode.conf` (located at `$GOPATH/pkg/mod/github.com/tinode/chat@vX.XX.X/server/`). Check that the database connection parameters are correct for your database. If you are using MySQL make sure [DSN](https://github.com/go-sql-driver/mysql#dsn-data-source-name) in `"mysql"` section is appropriate for your MySQL installation. Option `parseTime=true` is required. +```js + "mysql": { + "dsn": "root@tcp(localhost)/tinode?parseTime=true", + "database": "tinode" + }, +``` + +6. Make sure you specify the adapter name in your `tinode.conf`. E.g. you want to run Tinode with MySQL: +```js + "store_config": { + ... + "use_adapter": "mysql", + ... + }, +``` + +7. Now that you have built the binaries, follow instructions in the _Running a Standalone Server_ section. + + +## Running a Standalone Server + +If you followed instructions in the previous section then the Tinode binaries are installed in `$GOPATH/bin/`, the sources and supporting files are located in `$GOPATH/pkg/mod/github.com/tinode/chat@vX.XX.X/`, where `X.XX.X` is the version you installed, for example `0.19.1`. + +Switch to sources directory (replace `X.XX.X` with your actual version, such as `0.19.1`): +``` +cd $GOPATH/pkg/mod/github.com/tinode/chat@vX.XX.X +``` + +1.

Run DB initializer + ``` + $GOPATH/bin/tinode-db -config=./tinode-db/tinode.conf + ``` + add `-data=./tinode-db/data.json` flag if you want sample data to be loaded: + ``` + $GOPATH/bin/tinode-db -config=./tinode-db/tinode.conf -data=./tinode-db/data.json + ``` + + DB initializer needs to be run only once per installation. See [instructions](tinode-db/README.md) for more options. + +3. Unpack JS client to a directory, for instance `$HOME/tinode/webapp/` by unzipping `https://github.com/tinode/webapp/archive/master.zip` and `https://github.com/tinode/tinode-js/archive/master.zip` to the same directory. + +4. Copy or symlink template directory `./server/templ` to `$GOPATH/bin/templ` + ``` + ln -s ./server/templ $GOPATH/bin + ``` + +5. Run the server + ``` + $GOPATH/bin/server -config=./server/tinode.conf -static_data=$HOME/tinode/webapp/ + ``` + +6. Test your installation by pointing your browser to [http://localhost:6060/](http://localhost:6060/). The static files from the `-static_data` path are served at web root `/`. You can change this by editing the line `static_mount` in the config file. + +**Important!** If you are running Tinode alongside another webserver, such as Apache or nginx, keep in mind that you need to launch the webapp from the URL served by Tinode. Otherwise it won't work. + + +## Running a Cluster + +- Install and run the database, run DB initializer, unpack JS files, and link or copy template directory as described in the previous section. Both MySQL and RethinkDB supports [cluster](https://www.mysql.com/products/cluster/) [mode](https://www.rethinkdb.com/docs/start-a-server/#a-rethinkdb-cluster-using-multiple-machines). You may consider it for added resiliency. + +- Cluster expects at least two nodes. A minimum of three nodes is recommended. + +- The following section configures the cluster. + +``` + "cluster_config": { + // Name of the current node. + "self": "", + // List of all cluster nodes, including the current one. + "nodes": [ + {"name": "one", "addr":"localhost:12001"}, + {"name": "two", "addr":"localhost:12002"}, + {"name": "three", "addr":"localhost:12003"} + ], + // Configuration of failover feature. Don't change. + "failover": { + "enabled": true, + "heartbeat": 100, + "vote_after": 8, + "node_fail_after": 16 + } + } +``` +* `self` is the name of the current node. Generally it's more convenient to specify the name of the current node at the command line using `cluster_self` option. Command line value overrides the config file value. If the value is not provided either in the config file or through the command line, the clustering is disabled. +* `nodes` defines individual cluster nodes. The sample defines three nodes named `one`, `two`, and `tree` running at the localhost at the specified cluster communication ports. Cluster addresses don't need to be exposed to the outside world. +* `failover` is an experimental feature which migrates topics from failed cluster nodes keeping them accessible: + * `enabled` turns on failover mode; failover mode requires at least three nodes in the cluster. + * `heartbeat` interval in milliseconds between heartbeats sent by the leader node to follower nodes to ensure they are accessible. + * `vote_after` number of failed heartbeats before a new leader node is elected. + * `node_fail_after` number of heartbeats that a follower node misses before it's considered to be down. + +If you are testing the cluster with all nodes running on the same host, you also must override the `listen` and `grpc_listen` ports. Here is an example for launching two cluster nodes from the same host using the same config file: +``` +$GOPATH/bin/tinode -config=./server/tinode.conf -static_data=./server/webapp/ -listen=:6060 -grpc_listen=:6080 -cluster_self=one & +$GOPATH/bin/tinode -config=./server/tinode.conf -static_data=./server/webapp/ -listen=:6061 -grpc_listen=:6081 -cluster_self=two & +``` +A bash script [run-cluster.sh](./server/run-cluster.sh) may be found useful. + +### Enabling Push Notifications + +Follow [instructions](./docs/faq.md#q-how-to-setup-push-notifications-with-google-fcm). + + +### Enabling Video Calls + +Video calls use [WebRTC](https://en.wikipedia.org/wiki/WebRTC). WebRTC is a peer to peer protocol: once the call is established, the client applications exchange data directly. Direct data exchange is efficient but creates a problem when the parties are not accessible from the internet. WebRTC solves it by means of [ICE](https://en.wikipedia.org/wiki/Interactive_Connectivity_Establishment) servers which implement protocols [TURN(S)](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT) and [STUN](https://en.wikipedia.org/wiki/STUN) as fallback. + +Tinode does not provide ICE servers out of the box. You must install and configure (or purchase) your own servers otherwise video and voice calling will not be available. + +Once you obtain the ICE TURN/STUN configuration from your service provider, add it to `tinode.conf` section `"webrtc"` - `"ice_servers"` (or `"ice_servers_file"`). Also change `"webrtc"` - `"enabled"` to `true`. An example configuration is provided in the `tinode.conf` for illustration only. IT WILL NOT FUNCTION because it uses dummy values instead of actual server addresses. + +You may find this information useful for choosing the servers: https://gist.github.com/yetithefoot/7592580 + + +### Note on Running the Server in Background + +There is [no clean way](https://github.com/golang/go/issues/227) to daemonize a Go process internally. One must use external tools such as shell `&` operator, `systemd`, `launchd`, `SMF`, `daemon tools`, `runit`, etc. to run the process in the background. + +Specific note for [nohup](https://en.wikipedia.org/wiki/Nohup) users: an `exit` must be issued immediately after `nohup` call to close the foreground session cleanly: + +``` +nohup $GOPATH/bin/server -config=./server/tinode.conf -static_data=$HOME/tinode/webapp/ & +exit +``` + +Otherwise `SIGHUP` may be received by the server if the shell connection is broken before the ssh session has terminated (indicated by `Connection to XXX.XXX.XXX.XXX port 22: Broken pipe`). In such a case the server will shutdown because `SIGHUP` is intercepted by the server and interpreted as a shutdown request. + +For more details see https://github.com/tinode/chat/issues/25. diff --git a/LICENSE b/LICENSE index e69de29..94a9ed0 100644 --- a/LICENSE +++ b/LICENSE @@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

See screenshots below. + +### Android + +[Tinode for Android](https://play.google.com/store/apps/details?id=co.tinode.tindroidx) a.k.a Tindroid is stable and functional ([source](https://github.com/tinode/tindroid)).

Tinodios is stable and functional ([source](https://github.com/tinode/ios)). See the screenshots below. + + +## Demo/Sandbox + +A sandboxed demo service is available at https://sandbox.tinode.co/. + +Log in as one of `alice`, `bob`, `carol`, `dave`, `frank`. Password is `123`, e.g. login for `alice` is `alice123`. You can discover other users by email or phone by prefixing them with `email:` or `tel:` respectively. Emails are `@example.com`, e.g. `alice@example.com`, phones are `+17025550001` through `+17025550009`. + +When you register a new account you are asked for an email address to send validation code to. For demo purposes you may use `123456` as a universal validation code. The code you get in the email is also valid. + +### Sandbox Notes + +* The sandbox server is reset (all data wiped) every night at 3:15am Pacific time. An error message `User not found or offline` means the server was reset while you were connected. If you see it on the web, reload and relogin. On Android log out and re-login. If the database was changed, delete the app then reinstall. +* Sandbox user `Tino` is a [basic chatbot](./chatbot) which responds with a [random quote](http://fortunes.cat-v.org/) to any message. +* As generally accepted, when you register a new account you are asked for an email address. The server will send an email with a verification code to that address and you can use it to validate the account. To make things easier for testing, the server will also accept `123456` as a verification code. Remove line `"debug_response": "123456"` from `tinode.conf` to disable this option. +* The sandbox server is configured to use [ACME](https://letsencrypt.org/) TLS [implementation](https://godoc.org/golang.org/x/crypto/acme) with hard-coded requirement for [SNI](https://en.wikipedia.org/wiki/Server_Name_Indication). If you are unable to connect then the most likely reason is your TLS client's missing support for SNI. Use a different client. +* The default web app loads a single minified javascript bundle and minified CSS. The un-minified version is also available at https://sandbox.tinode.co/index-dev.html +* [Docker images](https://hub.docker.com/u/tinode/) with the same demo are available. +* You are welcome to test your client software against the sandbox, hack it, etc. No DDoS-ing though please. + +## Features + +### Supported + +* Multiple native platforms: + * [Android](https://github.com/tinode/tindroid/) (Java) + * [iOS](https://github.com/tinode/ios) (Swift) + * [Web](https://github.com/tinode/webapp/) (React.js) + * Scriptable [command line](tn-cli/) (Python) +* User features: + * One-on-one and group messaging. + * Video and voice calls.

Conceptually it loosely follows a [publish-subscribe](https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern) model. + +Server connects sessions, users, and topics. Session is a network connection between a client application and the server. User represents a human being who connects to the server with a session. Topic is a named communication channel which routes content between sessions. + +Users and topics are assigned unique IDs. User ID is a string with 'usr' prefix followed by base64-URL-encoded pseudo-random 64-bit number, e.g. `usr2il9suCbuko`. Topic IDs are described below. + +Clients such as mobile or web applications create sessions by connecting to the server over a websocket or through long polling. Client authentication is required in order to perform most operations. Client authenticates the session by sending a `{login}` packet. See [Authentication](#authentication) section for details. Once authenticated, the client receives a token which is used for authentication later. Multiple simultaneous sessions may be established by the same user. Logging out is not supported (and not needed). + +Once the session is established, the user can start interacting with other users through topics. The following +topic types are available: + +* `me` is a topic for managing one's profile and receiving notifications about other topics; `me` topic exists for every user. +* `fnd` topic is used for finding other users and topics; `fnd` topic also exists for every user. +* Peer to peer topic is a communication channel strictly between two users. Each participant sees topic name as the ID of the other participant: 'usr' prefix followed by a base64-URL-encoded numeric part of user ID, e.g. `usr2il9suCbuko`. +* Group topic is a channel for multi-user communication. It's named as 'grp' followed by 11 pseudo-random characters, i.e. `grpYiqEXb4QY6s`. Group topics must be explicitly created. + +Session joins a topic by sending a `{sub}` packet. Packet `{sub}` serves three functions: creating a new topic, subscribing user to a topic, and attaching session to a topic. See [`{sub}`](#sub) section below for details. + +Once the session has joined the topic, the user may start generating content by sending `{pub}` packets. The content is delivered to other attached sessions as `{data}` packets. + +The user may query or update topic metadata by sending `{get}` and `{set}` packets. + +Changes to topic metadata, such as changes in topic description, or when other users join or leave the topic, is reported to live sessions with `{pres}` (presence) packet. The `{pres}` packet is sent either to the topic being affected or to the `me` topic. + +When user's `me` topic comes online (i.e. an authenticated session attaches to `me` topic), a `{pres}` packet is sent to `me` topics of all other users, who have peer to peer subscriptions with the first user. + +## General Considerations + +Timestamps are always represented as [RFC 3339](http://tools.ietf.org/html/rfc3339)-formatted string with precision up to milliseconds and timezone always set to UTC, e.g. `"2015-10-06T18:07:29.841Z"`. + +Whenever base64 encoding is mentioned, it means base64 URL encoding with padding characters stripped, see [RFC 4648](http://tools.ietf.org/html/rfc4648). + +The `{data}` packets have server-issued sequential IDs: base-10 numbers starting at 1 and incrementing by one with every message. They are guaranteed to be unique per topic. + +In order to connect requests to responses, client may assign message IDs to all packets set to the server. These IDs are strings defined by the client. Client should make them unique at least per session. The client-assigned IDs are not interpreted by the server, they are returned to the client as is. + +## Connecting to the Server + +There are three ways to access the server over the network: websocket, long polling, and [gRPC](https://grpc.io/). + +When the client establishes a connection to the server over HTTP(S), such as over a websocket or long polling, the server offers the following endpoints: + * `/v0/channels` for websocket connections + * `/v0/channels/lp` for long polling + * `/v0/file/u` for file uploads + * `/v0/file/s` for serving files (downloads) + +`v0` denotes API version (currently zero). Every HTTP(S) request must include the API key. The server checks for the API key in the following order: +* HTTP header `X-Tinode-APIKey` +* URL query parameter `apikey` (/v0/file/s/abcdefg.jpeg?apikey=...) +* Form value `apikey` +* Cookie `apikey` + +A default API key is included with every demo app for convenience. Generate your own key for production using [`keygen` utility](../keygen). + +Once the connection is opened, the client must issue a `{hi}` message to the server. Server responds with a `{ctrl}` message which indicates either success or an error. The `params` field of the response contains server's protocol version `"params":{"ver":"0.15"}` and may include other values. + +### gRPC + +See definition of the gRPC API in the [proto file](../pbx/model.proto). gRPC API has slightly more functionality than the API described in this document: it allows the `root` user to send messages on behalf of other users as well as delete users. + +The `bytes` fields in protobuf messages expect JSON-encoded UTF-8 content. For example, a string should be quoted before being converted to bytes as UTF-8: `[]byte("\"some string\"")` (Go), `'"another string"'.encode('utf-8')` (Python 3). + +### WebSocket + +Messages are sent in text frames, one message per frame. Binary frames are reserved for future use. By default server allows connections with any value in the `Origin` header. + +### Long Polling + +Long polling works over `HTTP POST` (preferred) or `GET`. In response to client's very first request server sends a `{ctrl}` message containing `sid` (session ID) in `params`. Long polling client must include `sid` in every subsequent request either in the URL or in the request body. + +Server allows connections from all origins, i.e. `Access-Control-Allow-Origin: *` + +### Out of Band Large Files + +Large files are sent out of band using `HTTP POST` as `Content-Type: multipart/form-data`. See [below](#out-of-band-handling-of-large-files) for details. + +### Running Behind a Reverse Proxy + +Tinode server can be set up to run behind a reverse proxy, such as NGINX. For efficiency it can accept client connections from Unix sockets by setting `listen` and/or `grpc_listen` config parameters to the path of the Unix socket file, e.g. `unix:/run/tinode.sock`. The server may also be configured to read peer's IP address from `X-Forwarded-For` HTTP header by setting `use_x_forwarded_for` config parameter to `true`. + +## Users + +User is meant to represent a person, an end-user: producer and consumer of messages. + +Users are generally assigned one of the two authentication levels: authenticated `auth` or anonymous `anon`. The third level `root` is only accessible over `gRPC` where it permits the `root` to send messages on behalf of other users. + +When a connection is first established, the client application can send either an `{acc}` or a `{login}` message which authenticates the user at one the levels. + +Each user is assigned a unique ID. The IDs are composed as `usr` followed by base64-encoded 64-bit numeric value, e.g. `usr2il9suCbuko`. Users also have the following properties: + +* `created`: timestamp when the user record was created +* `updated`: timestamp of when user's `public` or `trusted` was last updated +* `status`: state of the account +* `username`: unique string used in `basic` authentication; username is not accessible to other users +* `defacs`: object describing user's default access mode for peer to peer conversations with authenticated and anonymous users; see [Access control](#access-control) for details + * `auth`: default access mode for authenticated `auth` users + * `anon`: default access for anonymous `anon` users +* `trusted`: an application-defined object issued by the system administration. Anyone can read it but only system administrators can change it. +* `public`: an application-defined object that describes the user. Anyone can query user for `public` data. +* `private`: an application-defined object that is unique to the current user and accessible only by the user. +* `tags`: [discovery](#fnd-and-tags-finding-users-and-topics) and credentials. + +User's account has a state. The following states are defined: + * `ok` (normal): the default state which means the account is not restricted in any way and can be used normally; + * `susp` (suspended): the user is prevented from accessing the account as well as not found through [search](#fnd-and-tags-finding-users-and-topics); the state can be assigned by the administrator and fully reversible. + * `del` (soft-deleted): user is marked as deleted but user's data is retained; un-deleting the user is not currenly supported. + * `undef` (undefined): used internally by authenticators; should not be used elsewhere. + +A user may maintain multiple simultaneous connections (sessions) with the server. Each session is tagged with a client-provided `User Agent` string intended to differentiate client software. + +Logging out is not supported by design. If an application needs to change the user, it should open a new connection and authenticate it with the new user credentials. + + +### Authentication + +Authentication is conceptually similar to [SASL](https://en.wikipedia.org/wiki/Simple_Authentication_and_Security_Layer): it's provided as a set of adapters each implementing a different authentication method. Authenticators are used during account registration [`{acc}`](#acc) and during [`{login}`](#login). The server comes with the following authentication methods out of the box: + + * `token` provides authentication by a cryptographic token. + * `basic` provides authentication by a login-password pair. + * `anonymous` is designed for cases where users are temporary, such as handling customer support requests through chat. + * `rest` is a [meta-method](../server/auth/rest/) which allows use of external authentication systems by means of JSON RPC. + +Any other authentication method can be implemented using adapters. + +The `token` is intended to be the primary means of authentication. Tokens are designed in such a way that token authentication is light weight. For instance, token authenticator generally does not make any database calls, all processing is done in-memory. All other authentication methods are intended to be used only to obtain or refresh the token. Once the token is obtained, subsequent logins should use it. + +The `basic` authentication scheme expects `secret` to be a base64-encoded string of a string composed of a user name followed by a colon `:` followed by a plan text password. User name in the `basic` scheme must not contain the colon character `:` (ASCII 0x3A). + +The `anonymous` scheme can be used to create accounts, it cannot be used for logging in: a user creates an account using `anonymous` scheme and obtains a cryptographic token which it uses for subsequent `token` logins. If the token is lost or expired, the user is no longer able to access the account. + +Compiled-in authenticator names may be changed by using `logical_names` configuration feature. For example, a custom `rest` authenticator may be exposed as `basic` instead of default one or `token` authenticator could be hidden from users. The feature is activated by providing an array of mappings in the config file: `logical_name:actual_name` to rename or `actual_name:` to hide. For instance, to use a `rest` service for basic authentication use `"logical_names": ["basic:rest"]`. + + +#### Creating an Account + +When a new account is created, the user must inform the server which authentication method will be later used to gain access to this account as well as provide shared secret, if appropriate. Only `basic` and `anonymous` can be used during account creation. The `basic` requires the user to generate and send a unique login and password to the server. The `anonymous` does not exchange secrets. + +User may optionally set `{acc login=true}` to use the new account for immediate authentication. When `login=false` (or not set), the new account is created but the authentication status of the session which created the account remains unchanged. When `login=true` the server will attempt to authenticate the session with the new account, the `{ctrl}` response to the `{acc}` request will contain the authentication token on success. This is particularly important for the `anonymous` authentication because that's the only time when the authentication token can be retrieved. + +#### Logging in + +Logging in is performed by issuing a `{login}` request. Logging in is possible with `basic` and `token` only. Response to any login is a `{ctrl}` message with either a code 200 and a token which can be used in subsequent logins with `token` authentication, or a code 300 request for additional information, such as verifying credentials or responding to a method-dependent challenge in multi-step authentication, or a code 4xx error. + +Token has server-configured expiration time so it needs to be periodically refreshed. + +#### Changing Authentication Parameters + +User may change authentication parameters, such as changing login and password, by issuing an `{acc}` request. Only `basic` authentication currently supports changing parameters: +```js +acc: { + id: "1a2b3", // string, client-provided message id, optional + user: "usr2il9suCbuko", // user being affected by the change, optional + token: "XMg...g1Gp8+BO0=", // authentication token if the session + // is not yet authenticated, optional. + scheme: "basic", // authentication scheme being updated. + secret: base64encode("new_username:new_password") // new parameters +} +``` +In order to change just the password, `username` should be left empty, i.e. `secret: base64encode(":new_password")`. + +If the session is not authenticated, the request must include a `token`. It can be a regular authentication token obtained during login, or a restricted token received through [Resetting a Password](#resetting-a-password) process. If the session is authenticated, the token must not be included. If the request is authenticated for access level `ROOT`, then the `user` may be set to a valid ID of another user. Otherwise it must be blank (defaulting to the current user) or equal to the ID of the current user. + + +#### Resetting a Password, i.e. "Forgot Password" + +To reset login or password, (or any other authentication secret, if such action is supported by the authenticator), one sends a `{login}` message with the `scheme` set to `reset` and the `secret` containing a base64-encoded string "`authentication scheme to reset secret for`:`reset method`:`reset method value`". Most basic case of resetting a password by email is +```js +login: { + id: "1a2b3", + scheme: "reset", + secret: base64encode("basic:email:jdoe@example.com") +} +``` +where `jdoe@example.com` is an earlier validated user's email. + +If the email matches the registration, the server will send a message using specified method and address with instructions for resetting the secret. The email contains a restricted security token which the user can include into an `{acc}` request with the new secret as described in [Changing Authentication Parameters](#changing-authentication-parameters). + +### Suspending a User + +User's account can be suspended by service administrator. Once the account is suspended, the user is no longer able to login and use the service. + +Only the `root` user may suspend the account. To suspend the account the root user sends the following message: +```js +acc: { + id: "1a2b3", // string, client-provided message id, optional + user: "usr2il9suCbuko", // user being affected by the change + status: "susp" +} +``` +Sending the same message with `status: "ok"` un-suspends the account. A root user may check account status by executing `{get what="desc"}` command against user's `me` topic. + + +### Credential Validation + +Server may be optionally configured to require validation of certain credentials associated with the user accounts and authentication scheme. For instance, it's possible to require user to provide a unique email or a phone number, or to solve a captcha as a condition of account registration. + +The server supports verification of email out of the box with just a configuration change. is mostly functional, verification of phone numbers is not functional because a commercial subscription is needed in order to be able to send text messages (SMS). + +If certain credentials are required, then user must maintain them in validated state at all times. It means if a required credential has to be changed, the user must first add and validate the new credential and only then remove the old one. + +Credentials are initially assigned at registration time by sending an `{acc}` message, added using `{set topic="me"}`, deleted using `{del topic="me"}`, and queries by `{get topic="me"}` messages. Credentials are verified by the client by sending either a `{login}` or an `{acc}` message. + + +### Access Control + +Access control manages user's access to topics through access control lists (ACLs). The access is assigned individually to each user-topic pair (subscription). + +Access control is mostly usable for group topics. Its usability for `me` and P2P topics is limited to managing presence notifications and banning uses from initiating or continuing P2P conversations. All channel readers are given the same permissions. + +User's access to a topic is defined by two sets of permissions: user's desired permissions "want", and permissions granted to user by topic's manager(s) "given". Each permission is represented by a bit in a bitmap. It can be either present or absent. The actual access is determined as a bitwise AND of wanted and given permissions. The permissions are communicated in messages as a set of ASCII characters, where presence of a character means a set permission bit: + +* No access: `N` is not a permission per se but an indicator that permissions are explicitly cleared/not set. It usually indicates that the default permissions should *not* be applied. +* Join: `J`, permission to subscribe to a topic +* Read: `R`, permission to receive `{data}` packets +* Write: `W`, permission to `{pub}` to topic +* Presence: `P`, permission to receive presence updates `{pres}` +* Approve: `A`, permission to approve requests to join a topic, remove and ban members; a user with such permission is topic's administrator +* Sharing: `S`, permission to invite other people to join the topic +* Delete: `D`, permission to hard-delete messages; only owners can completely delete topics +* Owner: `O`, user is the topic owner; the owner can assign any other permission to any topic member, change topic description, delete topic; topic may have a single owner only; some topics have no owner + +When a user subscribes to a topic or starts a chat with another user, the access permissions are either set explicitly or assigned by default `defacs`. Access permissions can be modified by sending `{set}` messages. + +A client may set explicit permissions in `{sub}` and `{set}` messages. If the permissions are missing or set to an empty string (not `N`!), Tinode will use default permissions `defacs` assigned earlir. If no default permissions are found, the authenticated users in group topics will receive a `JRWPS` access, in P2P topics will get `JRWPA`; anonymous users will receive `N` (no access) which means every subscription request must be explicitly approved by the topic manager. + +Default access is defined for two categories of users: authenticated and anonymous. The default access value is applied as a "given" permission to all new subscriptions. Topic's default access is established at the topic creation time by `{sub.desc.defacs}` and can be subsequently modified by the owner by sending `{set}` messages. Likewise, user's default access is established at the account creation time by `{acc.desc.defacs}` and can be modified by the user by sending a `{set}` message to `me` topic. + + +## Topics + +Topic is a named communication channel for one or more people. Topics have persistent properties. These topic properties can be queried by `{get what="desc"}` message. + +Topic properties independent of the user making the query: +* `created`: timestamp of topic creation time +* `updated`: timestamp of when topic's `trusted`, `public`, or `private` was last updated +* `touched`: timestamp of the last message sent to the topic +* `defacs`: object describing topic's default access mode for authenticated and anonymous users; see [Access control](#access-control) for details + * `auth`: default access mode for authenticated users + * `anon`: default access for anonymous users +* `seq`: integer server-issued sequential ID of the latest `{data}` message sent through the topic +* `trusted`: an application-defined object issued by the system administrators. Anyone can read it but only administrators can change it. +* `public`: an application-defined object that describes the topic. Anyone who can subscribe to topic can receive topic's `public` data, only topic `owner` can change it. + +User-dependent topic properties: +* `acs`: object describing given user's current access permissions; see [Access control](#access-control) for details + * `want`: access permission requested by this user + * `given`: access permissions given to this user +* `private`: an application-defined object that is unique to the current user (topic subscriber). + +Topic usually have subscribers. One of the subscribers may be designated as topic owner (`O` access permission) with full access permissions. The list of subscribers can be queries with a `{get what="sub"}` message. The list of subscribers is returned in a `sub` section of a `{meta}` message. + +### `me` Topic + +Topic `me` is automatically created for every user at the account creation time. It serves as means of managing account information, receiving presence notification from people and topics of interest. Topic `me` has no owner. The topic cannot be deleted or unsubscribed from. One can `leave` the topic which will stop all relevant communication and indicate that the user is offline (although the user may still be logged in and may continue to use other topics). + +Joining or leaving `me` generates a `{pres}` presence update sent to all users who have peer to peer topics with the given user and `P` permissions set. + +Topic `me` is read-only. `{pub}` messages to `me` are rejected. + +Message `{get what="desc"}` to `me` is automatically replied with a `{meta}` message containing `desc` section with the topic parameters (see intro to [Topics](#topics) section). The `public` parameters of `me` topic is data that the user wants to show to his/her connections. Changing it changes `public` not just for the `me` topic, but also everywhere where user's `public` is shown, such as `public` of all user's peer to peer topics. + +Message `{get what="sub"}` to `me` is different from any other topic as it returns the list of topics that the current user is subscribed to as opposite to the expected user's subscription to `me`. +* seq: server-issued numeric id of the last message in the topic +* recv: seq value self-reported by the current user as received +* read: seq value self-reported by the current user as read +* seen: for P2P subscriptions, timestamp of user's last presence and User Agent string are reported + * when: timestamp when the user was last online + * ua: user agent string of the user's client software last used + +Message `{get what="data"}` to `me` is rejected. + +Internally the `me` topics are not persisted separately from the users. The `me` topics don't exist in the `topics` table or collection, they are created in memory from the `users` database record. + +### `slf` Topic + +Topic `slf` (self) provides mechanism for storing information, like bookmarks or saved messages. Messages sent to `slf` are accessible only by the user who sent them. + +This topic is created automatically when the user subscribes to it for the first time. + +### `fnd` and Tags: Finding Users and Topics + +Topic `fnd` is automatically created for every user at the account creation time. It serves as an endpoint for discovering other users and group topics. Users and group topics can be discovered by `tags`. Tags are optionally assigned at the topic or user creation time then can be updated by using `{set what="tags"}` against a `me` or a group topic. + +A tag is an arbitrary case-insensitive Unicode string (forced to lowercase on the server) up to 96 characters long which may contain characters from `Letter` and `Number` Unicode [classes/categories](https://en.wikipedia.org/wiki/Unicode_character_property#General_Category) as well as any of the following ASCII characters: `_`, `.`, `+`, `-`, `@`, `#`, `!`, `?`. + +Tag may have a prefix which serves as a namespace. The prefix is a 2-16 character string which starts with a letter [a-z] and may contain lowercase ASCII letters and numbers followed by a colon `:`, ex. prefixed phone tag `tel:+14155551212` or prefixed email tag `email:alice@example.com`. Some prefixed tags are optionally enforced to be unique. In that case only one user or topic may have such a tag. Certain tags may be forced to be immutable to the user, i.e. user's attempts to add or remove an immutable tag will be rejected by the server. + +The tags are indexed server-side and used in user and topic discovery. Search returns users and topics sorted by the number of matched tags in descending order. + +In order to find users or topics, a user sets either `public` or `private` parameter of the `fnd` topic to a search query (see [Query language](#query-language)) then issues a `{get topic="fnd" what="sub"}` request. If both `public` and `private` are set, the `public` query is used. The `private` query is persisted across sessions and devices, i.e. all user's sessions see the same `private` query. The value of the `public` query is ephemeral, i.e. it's not saved to database and not shared between user's sessions. The `private` query is intended for large queries which do not change often, such as finding matches for everyone in user's contact list on a mobile phone. The `public` query is intended to be short and specific, such as finding some topic or a user who is not in the contact list. + +The system responds with a `{meta}` message with the `sub` section listing details of the found users or topics formatted as subscriptions. + +Topic `fnd` is read-only. `{pub}` messages to `fnd` are rejected. + +_CURRENTLY UNSUPPORTED_ When a new user registers with tags matching the given query, the `fnd` topic will receive `{pres}` notification for the new user. + +[Plugins](../pbx) support `Find` service which can be used to replace default search with a custom one. + +Internally the `fnd` topics are not persisted separately from the users. The `fnd` topics don't exist in the `topics` table or collection, they are created in memory from the `users` database record. + +#### Query Language + +Tinode query language is used to define search queries for finding users and topics. The query is a string containing atomic terms separated by spaces or commas. The individual query terms are matched against user's or topic's tags. The individual terms may be written in an RTL language but the query as a whole is parsed left to right. Spaces are treated as the `AND` operator, commas (as well as commas preceded and/or followed by a space) as the `OR` operator. The order of operators is ignored: all `AND` tags are grouped together, all `OR` tags are grouped together. `OR` takes precedence over `AND`: if a tag is preceded of followed by a comma, it's an `OR` tag, otherwise an `AND`. For example, `aaa bbb, ccc` (`aaa AND bbb OR ccc`) is interpreted as `(bbb OR ccc) AND aaa`. + +Query terms containing spaces must convert spaces to underscores ` ` -> `_`, e.g. `new york` -> `new_york`. + +**Some examples:** +* `flowers`: find topics or users which contain tag `flowers`. +* `flowers travel`: find topics or users which contain both tags `flowers` and `travel`. +* `flowers, travel`: find topics or users which contain either tag `flowers` or `travel` (or both). +* `flowers travel, puppies`: find topics or users which contain `flowers` and either `travel` or `puppies`, i.e. `(travel OR puppies) AND flowers`. +* `flowers, travel puppies, kittens`: find topics or users which contain either one of `flowers`, `travel`, `puppies`, or `kittens`, i.e. `flowers OR travel OR puppies OR kittens`. The space between `travel` and `puppies` is treated as `OR` due to `OR` taking precedence over `AND`. + +#### Incremental Updates to Queries + +_CURRENTLY UNSUPPORTED_ Queries, particularly `fnd.private` could be arbitrarily large, limited only by the limits on the message size, and by the limits on the query size in the underlying database. Instead of rewriting the entire query to add or remove a term, terms can be added or removed incrementally. + +The incremental update request is processed left to right. It may contain the same term multiple times, i.e. `-a_tag+a_tag` is a valid request. + +#### Query Rewrite + +Finding users by login, phone or email requires query terms to be written with prefixes, i.e. `email:alice@example.com` instead of `alice@example.com`. This may present a problem to end users because it requires them to learn the query language. Tinode solves this problem by implementing _query rewrite_ on the server: if query term (tag) does not contain a prefix, server rewrites it by adding the appropriate prefix. In queries to `fnd.public` the original term is also kept (query `alice@example.com` is rewritten as `email:alice@example.com OR alice@example.com`), in queries to `fnd.private` only the rewritten term is kept (`alice@example.com` is rewritten as `email:alice@example.com`). All terms that look like email, for instance, `alice@example.com` are rewritten to `email:alice@example.com OR alice@example.com`. Terms which look like phone numbers are converted to [E.164](https://en.wikipedia.org/wiki/E.164) and also rewritten as `tel:+14155551212 OR +14155551212`. In addition, in queries to `fnd.public` all other unprefixed terms which look like logins are rewritten as logins: `alice` -> `basic:alice OR alice`. + +As described above, tags which look like phone numbers are converted to E.164 format. Such conversion requires an ISO 3166-1 alpha-2 country code. The following logic is used when converting phone number tags to E.164: +* If the tag already contains a country calling code, it's used as is: `+1(415)555-1212` -> `+14155551212`. +* If the tag has no prefix, country code is taken from the locale value set by the client in `lang` field of the `{hi}` message. +* If client has not provided the code in the `hi.lang`, the country code is taken from `default_country_code` field of the `tinode.conf`. +* If no `default_country_code` is set in `tinode.conf`, `US` country code is used. + +#### Possible Use Cases +* Restricting users to organisations. + An immutable tag(s) may be assigned to the user which denotes the organisation the user belongs to. When the user searches for other users or topics, the search can be restricted to always contain the tag. This approach can be used to segment users into organisations with limited visibility into each other. + +* Search by geographical location. + Client software may periodically assign a [geohash](https://en.wikipedia.org/wiki/Geohash) tag to the user based on current location. Searching for users in a given area would mean matching on geohash tags. + +* Search by numerical range, such as age range. + The approach is similar to geohashing. The entire range of numbers is covered by the smallest possible power of 2, for instance the range of human ages is covered by 27=128 years. The entire range is split in two halves: the range 0-63 is denoted by 0, 64-127 by 1. The operation is repeated with each subrange, i.e. 0-31 is 00, 32-63 is 01, 0-15 is 000, 32-47 is 010. Once completed, the age 30 will belong to the following ranges: 0 (0-63), 00 (0-31), 001 (16-31), 0011 (24-31), 00111 (28-31), 001111 (30-31), 0011110 (30). A 30 y.o. user is assigned a few tags to indicate the age, i.e. `age:00111`, `age:001111`, and `age:0011110`. Technically, all 7 tags may be assigned but usually it's impractical. To query for anyone in the age range 28-35 convert the range into a minimal number of tags: `age:00111` (28-31), `age:01000` (32-35). This query will match the 30 y.o. user by tag `age:00111`. + + +### Peer to Peer Topics + +Peer to peer (P2P) topics represent communication channels between strictly two users. The name of the topic is different for each of the two participants. Each of them sees the name of the topic as the user ID of the other participant: `usr` followed by base64 URL-encoded ID of the user. For example, if two users `usrOj0B3-gSBSs` and `usrIU_LOVwRNsc` start a P2P topic, the first one will see it as `usrIU_LOVwRNsc`, the second as `usrOj0B3-gSBSs`. The P2P topic has no owner. + +A P2P topic is created by one user subscribing to topic with the name equal to the ID of the other user. For instance, user `usrOj0B3-gSBSs` can establish a P2P topic with user `usrIU_LOVwRNsc` by sending a `{sub topic="usrIU_LOVwRNsc"}`. Tinode will respond with a `{ctrl}` packet with the name of the newly created topic as described above. The other user will receive a `{pres}` message on `me` topic with updated access permissions. + +Internally, P2P topics are stored as `p2p` followed by base64 URL encoded concatenation of two 64-bit user IDs, with the lower numeric value ID first: `p2pm7PvMGmdcx_uVkDRaSTbwA`. + +The 'public' parameter of P2P topics is user-dependent. For instance a P2P topic between users A and B would show user A's 'public' to user B and vice versa. If a user updates 'public', all user's P2P topics will automatically update 'public' too. + +The 'private' parameter of a P2P topic is defined by each participant individually as with any other topic type. + +### Group Topics + +Group topic represents a communication channel between multiple users. The name of a group topic is `grp` or `chn` followed by a string of characters from base64 URL-encoding set. No other assumptions can be made about internal structure or length of the group name. + +Group topics support limited number of subscribers (controlled by a `max_subscriber_count` parameter in configuration file) with access permissions of each subscriber managed individually. Group topics may also be enabled to support any number of read-only users - `readers`. All `readers` have the same access permissions. Group topics with enabled `readers` are called `channels`. + +A group topic is created by sending a `{sub}` message with the topic field set to string `new` or `nch` optionally followed by any characters, e.g. `new` or `newAbC123` are equivalent. Tinode will respond with a `{ctrl}` message with the name of the newly created topic, i.e. `{sub topic="new"}` is replied with `{ctrl topic="grpmiKBkQVXnm3P"}`. If topic creation fails, the error is reported on the original topic name, i.e. `new` or `newAbC123`. The user who created the topic becomes topic owner. Ownership can be transferred to another user with a `{set}` message but one user must remain the owner at all times. + +A `channel` topic is different from the non-channel group topic in the following ways: + + * Channel topic is created by sending `{sub topic="nch"}`. Sending `{sub topic="new"}` will create a group topic without enabling channel functionality. + * Sending `{sub topic="chnAbC123"}` will create a `reader` subscription to a channel. A non-channel topic will reject such subscription request. + * When searching for topics using [`fnd`](#fnd-and-tags-finding-users-and-topics), channels will show addresses with `chn` prefixes, non-channel topic will show with `grp` prefixes. + * Messages received by readers on channels have no `From` field. Normal subscribers will receive messages with `From` containing ID of the sender. + * Default permissions for a channel and non-channel group topics are different: channel group topic grants no permissions at all. + * A subscriber joining or leaving the topic (regular or channel-enabled) generates a `{pres}` message to all other subscribers who are currently in the joined state with the topic and have appropriate permissions. Reader joining or leaving the channel generates no `{pres}` message. + +### `sys` Topic + +The `sys` topic serves as an always available channel of communication with the system administrators. A normal non-root user cannot subscribe to `sys` but can publish to it without subscription. Existing clients use this channel to report abuse by sending a Drafty-formatted `{pub}` message with the report as JSON attachment. A root user can subscribe to `sys` topic. Once subscribed, the root user will receive messages sent to `sys` topic by other users. + +## Using Server-Issued Message IDs + +Tinode provides basic support for client-side caching of `{data}` messages in the form of server-issued sequential message IDs. The client may request the last message id from the topic by issuing a `{get what="desc"}` message. If the returned ID is greater than the ID of the latest received message, the client knows that the topic has unread messages and their count. The client may fetch these messages using `{get what="data"}` message. The client may also paginate history retrieval by using message IDs. + +## User Agent and Presence Notifications + +A user is reported as being online when one or more of user's sessions are attached to the `me` topic. Client-side software identifies itself to the server using `ua` (user agent) field of the `{login}` message. The _user agent_ is published in `{meta}` and `{pres}` messages in the following way: + + * When user's first session attaches to `me`, the _user agent_ from that session is broadcast in the `{pres what="on" ua="..."}` message. + * When multiple user sessions are attached to `me`, the _user agent_ of the session where the most recent action has happened is reported in `{pres what="ua" ua="..."}`; the 'action' in this context means any message sent by the client. To avoid potentially excessive traffic, user agent changes are broadcast no more frequently than once a minute. + * When user's last session detaches from `me`, the _user agent_ from that session is recorded together with the timestamp; the user agent is broadcast in the `{pres what="off" ua="..."}` message and subsequently reported as the last online timestamp and user agent. + +An empty `ua=""` _user agent_ is not reported. I.e. if user attaches to `me` with non-empty _user agent_ then does so with an empty one, the change is not reported. An empty _user agent_ may be disallowed in the future. + +## Trusted, Public, Private, Auxiliary Fields + +Topics have `trusted`, `public`, `aux` fields, subscriptions have `private` fields. The primary difference between these fields is in access control: + + * `trusted`: writable by `ROOT` users, readable by anyone. + * `public`: writable by the `owner` or the user, readable by anyone. + * `aux`: writable by topic administrators, readable by subscribers. + * `private`: readable and writable only by the user who created the subscription. + +Generally, the fields are application-defined. The server does not enforce any particular structure of these fields except for `fnd` topic. At the same time, client software should use the same format for interoperability reasons. The following sections describe the format of these fields as they are implemented by all official clients. + +Although it's not yet enforced, if a third-party application defines custom keys, the key names should start with an `x-` followed by the application's fully qualified domain name, e.g. `x-example.com-value: "abc"`. The fields should contain primitive types only, i.e. `string`, `boolean`, `number`, or `null`. + +### Trusted + +The format of the optional `trusted` field in group and peer to peer topics is a set of key-value pairs; `fnd` and `sys` topics do not have the `trusted`. The field is writable by `ROOT` users, readable by anyone who has access to the topic or user. The following optional keys are currently defined: +```js +trusted: { + verified: true, // boolean, an indicator of a verified/trustworthy user or topic. + staff: true, // boolean, an indicator that the user or topic + // is a part of/belongs to the server administration. + danger: true // boolean, an indicator that the user or topic are untrustworthy. +} +``` + +### Public + +The format of the `public` field in group, peer to peer, systems topics is expected to be [theCard](./thecard.md). The field is writable by by the user for users, the topic owner for topics. The field is readable by anyone who has access to topic or user. + +The `fnd` topic expects `public` to be a string representing a [search query](#query-language)). + +### Private + +The format of the `private` field in group and peer to peer topics is a set of key-value pairs. The field is writable and readable by the user only. The following keys are currently defined: +```js +private: { + comment: "some comment", // string, optional user comment about a topic or a peer user + arch: true, // boolean, indicator that the topic is archived by the user, i.e. + // should not be shown in the UI with other non-archived topics. + accepted: "JRWS", // string, 'given' mode accepted by the user. + tpins: ["grpmiKBkQVXnm3P", "usrIU_LOVwRNsc"] // array of topic IDs to pin to the top of + // the contacts list; 'me' topic only. +} +``` + +The `fnd` topic expects `private` to be a string representing a [search query](#query-language)). + +### Auxiliary + +The format of the `aux` field is a set of key-value pairs. The `aux` is writable by topic admins and readable by all topic subscribers. The following keys are currently defined: + +```js +aux: { + pins: [1001, 23456] // array of integer message IDs to pin to the top of the message list. +} +``` + +## Format of Content + +Format of `content` field in `{pub}` and `{data}` is application-defined and as such the server does not enforce any particular structure of the field. At the same time, client software should use the same format for interoperability reasons. Currently the following two types of `content` are supported: + * Plain text + * [Drafty](./drafty.md) + +If Drafty is used, a message header `"head": {"mime": "text/x-drafty"}` must be set. + + +## Out-of-Band Handling of Large Files + +Large files create problems when sent in-band for multiple reasons: + * limits on database storage as in-band messages are stored in database fields + * in-band messages must be downloaded completely as a part of downloading chat history + +Tinode provides two endpoints for handling large files: `/v0/file/u` for uploading files and `v0/file/s` for downloading. The endpoints require the client to provide both [API key](#connecting-to-the-server) and login credentials. The server checks credentials in the following order: + +**Login credentials** + * HTTP header `Authorization` (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization) + * URL query parameters `auth` and `secret` (/v0/file/s/abcdefg.jpeg?auth=...&secret=...) + * Form values `auth` and `secret` + * Cookies `auth` and `secret` + +### Uploading + +To upload a file first create an RFC 2388 multipart request then send it to the server using HTTP POST. The server responds to the request either with a `307 Temporary Redirect` with the new upload URL, or with a `200 OK` and a `{ctrl}` message in response body: + +```js +ctrl: { + params: { + url: "/v0/file/s/mfHLxDWFhfU.pdf" + }, + code: 200, + text: "ok", + ts: "2018-07-06T18:47:51.265Z" +} +``` +If `307 Temporary Redirect` is returned, the client must retry the upload at the provided URL. The URL returned in `307` response should be used for just this one upload. All subsequent uploads should try the default URL first. + +The `ctrl.params.url` contains the path to the uploaded file at the current server. It could be either the full path like `/v0/file/s/mfHLxDWFhfU.pdf`, a relative path like `./mfHLxDWFhfU.pdf`, or just the file name `mfHLxDWFhfU.pdf`. Anything but the full path is interpreted against the default *download* endpoint `/v0/file/s/`. For instance, if `mfHLxDWFhfU.pdf` is returned then the file is located at `http(s)://current-tinode-server/v0/file/s/mfHLxDWFhfU.pdf`. + +Once the URL of the file is received, either immediately or after following the redirect, the client may use the URL to send a `{pub}` message with the uploaded file as an attachment, or, if the file is an image, as an avatar image for a topic or user profile (see [theCard](./thecard.md)). For example, the URL can be used in a [Drafty](./drafty.md)-formatted `pub.content` field: + +```js +{ + pub: { + id: "121103", + topic: "grpnG99YhENiQU", + head: { + mime: "text/x-drafty" + }, + content: { + ent: [ + { + data: { + mime: "image/jpeg", + name: "roses-are-red.jpg", + ref: "/v0/file/s/sJOD_tZDPz0.jpg", + size: 437265 + }, + tp: "EX" + } + ], + fmt: [ + { + at: -1, + key:0, + len:1 + } + ] + } + }, + extra: { + attachments: ["/v0/file/s/sJOD_tZDPz0.jpg"] + } +} +``` + +It's important to list the used URLs in the `extra: attachments[...]` field. Tinode server uses this field to maintain the uploaded file's use counter. Once the counter drops to zero for the given file (for instance, because a message with the shared URL was deleted or because the client failed to include the URL in the `extra.attachments` field), the server will garbage collect the file. Only relative URLs should be used. Absolute URLs in the `extra.attachments` field are ignored. The URL value is expected to be the `ctrl.params.url` returned in response to upload. + +### Downloading + +The serving endpoint `/v0/file/s` serves files in response to HTTP GET requests. The client must evaluate relative URLs against this endpoint, i.e. if it receives a URL `mfHLxDWFhfU.pdf` or `./mfHLxDWFhfU.pdf` it should interpret it as a path `/v0/file/s/mfHLxDWFhfU.pdf` at the current Tinode HTTP server. + +_Important!_ As a security measure, the client should not send security credentials if the download URL is absolute and leads to another server. + +## Push Notifications + +Tinode uses compile-time adapters for handling push notifications. The server comes with [Tinode Push Gateway](../server/push/tnpg/), [Google FCM](https://firebase.google.com/docs/cloud-messaging/), and `stdout` adapters. Tinode Push Gateway and Google FCM support Android with [Play Services](https://developers.google.com/android/guides/overview) (may not be supported by some Chinese phones), iOS devices and all major web browsers excluding Safari. The `stdout` adapter does not actually send push notifications. It's mostly useful for debugging, testing and logging. Other types of push notifications such as [TPNS](https://intl.cloud.tencent.com/product/tpns) can be handled by writing appropriate adapters. + +If you are writing a custom plugin, the notification payload is the following: +```js +{ + topic: "grpnG99YhENiQU", // Topic which received the message. + xfrom: "usr2il9suCbuko", // ID of the user who sent the message. + ts: "2019-01-06T18:07:30.038Z", // message timestamp in RFC3339 format. + seq: "1234", // sequential ID of the message (integer value sent as text). + mime: "text/x-drafty", // optional message MIME-Type. + content: "Lorem ipsum dolor sit amet, consectetur adipisci", // The first 80 characters of the message content as plain text. +} +``` + +### Tinode Push Gateway + +Tinode Push Gateway (TNPG) is a proprietary Tinode service which sends push notifications on behalf of Tinode. Internally it uses Google FCM and as such supports the same platforms as FCM. The main advantage of using TNPG over FCM is simplicity of configuration: mobile clients do not need to be recompiled, all is needed is a [configuration update](../server/push/tnpg/) on a server. + +### Google FCM + +[Google FCM](https://firebase.google.com/docs/cloud-messaging/) supports Android with [Play Services](https://developers.google.com/android/guides/overview), iPhone and iPad devices, and all major web browsers excluding Safari. In order to use FCM mobile clients (iOS, Android) must be recompiled with credentials obtained from Google. See [instructions](../server/push/fcm/) for details. + +### Stdout + +The `stdout` adapter is mostly useful for debugging and logging. It writes push payload to `STDOUT` where it can be redirected to file or read by some other process. + +## Video Calls + +[See separate document](call-establishment.md). + +## Link Previews + +Tinode provides an optional service which helps client applications generate link (URL) previews for inclusion into messages. The enpoint of this service (if enabled) is located at `/v0/urlpreview`. The service takes a single parameter `url`: + +``` +/v0/urlpreview?url=https%3A%2F%2Ftinode.co +``` +The first several kilobytes of the document at the given URL is fetched by issuing an HTTP(S) GET request. If the returned document has content-type `text/html`, the HTML is parsed for page title, description, and image URL. The result is formatted as JSON and returned as + +```json +{"title": "Page title", "description": "This is a page description", "image_url": "https://tinode.co/img/logo64x64.png"} +``` + +The link preview service requires authentication. It's exactly the same as authentication for [Out of Band Large Files](#out-of-band-handling-of-large-files). + +## Messages + +A message is a logically associated set of data. Messages are passed as JSON-formatted UTF-8 text. + +All client to server messages may have an optional `id` field. It's set by the client as means to receive an acknowledgement from the server that the message was received and processed. The `id` is expected to be a session-unique string but it can be any string. The server does not attempt to interpret it other than to check JSON validity. The `id` is returned unchanged by the server when it replies to the client message. + +Server requires strictly valid JSON, including double quotes around field names. For brevity the notation below omits double quotes around field names as well as outer curly brackets. Examples use `//` comments only for expressiveness. The comments cannot be used in actual communication with the server. + +For messages that update application-defined data, such as `{set}` `private` or `public` fields, when server-side +data needs to be cleared, use a string with a single Unicode DEL character "␡" (`\u2421`). I.e. sending `"public": null` will not clear the field, but sending `"public": "␡"` will. + +Any unrecognized fields are silently ignored by the server. + +### Client to Server Messages + +Every client to server message contains the main payload described in the sections below and an optional top-level field `extra`: +```js +{ + abc: { ... }, // Main payload, see sections below. + extra: { + attachments: ["/v0/file/s/sJOD_tZDPz0.jpg"], // Array of out-of-band attachments which have to be exempted from GC. + obo: "usr2il9suCbuko", // Alternative user ID set by the root user (obo = On Behalf Of). + authlevel: "auth" // Altered authentication level set by the root user. + } +} +``` +The `attachments` array lists URLs of files uploaded out of band. Such listing increments use counter of these files. Once the use counter drops to 0, the files will be automatically deleted. +The `obo` (On Behalf Of) can be set by the `root` user. If the `obo` is set, the server will treat the message as if it came from the specified user as opposite to the actual sender. +The `authlevel` is supplementary to the `obo` and permits setting custom authentication level for the user. A an `"auth"` level is used if the field is unset. + +#### `{hi}` + +Handshake message client uses to inform the server of its version and user agent. This message must be the first that +the client sends to the server. Server responds with a `{ctrl}` which contains server build `build`, wire protocol version `ver`, +session ID `sid` in case of long polling, as well as server constraints, all in `ctrl.params`. + +```js +hi: { + id: "1a2b3", // string, client-provided message id, optional + ver: "0.15.8-rc2", // string, version of the wire protocol supported by the client, required + ua: "JS/1.0 (Windows 10)", // string, user agent identifying client software, + // optional + dev: "L1iC2...dNtk2", // string, unique value which identifies this specific + // connected device for the purpose of push notifications; not + // interpreted by the server. + // see [Push notifications support](#push-notifications-support); optional + platf: "android", // string, underlying OS for the purpose of push notifications, one of + // "android", "ios", "web"; if missing, the server will try its best to + // detect the platform from the user agent string; optional + lang: "en-US", // human language of the client device; optional + tenant: "acme" // public enterprise code used to bind the session tenant; required +} +``` +The user agent `ua` is expected to follow [RFC 7231 section 5.5.3](http://tools.ietf.org/html/rfc7231#section-5.5.3) recommendation but the format is not enforced. The first message must include `tenant`. The resolved tenant is immutable for the lifetime of the session. The message can be sent more than once to update `ua`, `dev` and `lang` values. If sent more than once, the `ver` field of the second and subsequent messages must be either unchanged or not set, and `tenant` must be unchanged or omitted. + +#### `{acc}` + +Message `{acc}` creates users or updates `tags` or authentication credentials `scheme` and `secret` of exiting users. To create a new user set `user` to the string `new` optionally followed by any character sequence, e.g. `newr15gsr`. Either authenticated or anonymous session can send an `{acc}` message to create a new user. To update authentication data or validate a credential of the current user leave `user` unset. + +The `{acc}` message **cannot** be used to modify `desc` or `cred` of an existing user. Update user's `me` topic instead. + +```js +acc: { + id: "1a2b3", // string, client-provided message id, optional + user: "newABC123", // string, "new" optionally followed by any characters to create a new user, + // default: current user, optional + token: "XMgS...8+BO0=", // string, authentication token to use for the request if the + // session is not authenticated, optional + // Temporary authentication parameters for one-off actions, like password reset. + tmpscheme: "code", // name of the temp wuth scheme + tmpsecret: "XMgS...8+BO0=", // temp auth secret + status: "ok", // change user's status; no default value, optional. + authlevel: "auth", // authentication level of the user when UserID is set and not equal + // to the current user; Either "", "auth" or "anon"; default: "" + scheme: "basic", // authentication scheme for this account, required; + // "basic" and "anon" are currently supported for account creation. + secret: base64encode("username:password"), // string, base64 encoded secret for the chosen + // authentication scheme; to delete a scheme use a string with a single DEL + // Unicode character "\u2421"; "token" and "basic" cannot be deleted + login: true, // boolean, use the newly created account to authenticate current session, + // i.e. create account and immediately use it to login. + tags: ["alice johnson",... ], // array of tags for user discovery; see 'fnd' topic for + // details, optional (if missing, user will not be discoverable other than + // by login) + cred: [ // account credentials which require verification, such as email or phone number. + { + meth: "email", // string, verification method, e.g. "email", "tel", "recaptcha", etc. + val: "alice@example.com", // string, credential to verify such as email or phone + resp: "178307", // string, verification response, optional + params: { ... } // parameters, specific to the verification method, optional + }, + ... + ], + + desc: { // object, user initialisation data closely matching that of table + // initialisation; used only when creating an account; optional + defacs: { + auth: "JRWS", // string, default access mode for peer to peer conversations + // between this user and other authenticated users + anon: "N" // string, default access mode for peer to peer conversations + // between this user and anonymous (un-authenticated) users + }, // Default access mode for user's peer to peer topics + public: { ... }, // application-defined payload to describe user, + // available to everyone + private: { ... } // private application-defined payload available only to user + // through 'me' topic + } +} +``` + +Server responds with a `{ctrl}` message with `params` containing details of the new user account such as user ID and, in case of `login: true`, authentication token. If `desc.defacs` is missing, the server will assign server-default access permissions to new account. + +The only supported authentication schemes for account creation are `basic` and `anonymous`. + +#### `{login}` + +Login is used to authenticate the current session. + +```js +login: { + id: "1a2b3", // string, client-provided message id, optional + scheme: "basic", // string, authentication scheme; "basic", + // "token", and "reset" are currently supported + secret: base64encode("username:password"), // string, base64-encoded secret for the chosen + // authentication scheme, required + cred: [ + { + meth: "email", // string, verification method, e.g. "email", "tel", "captcha", etc, required + resp: "178307" // string, verification response, required + }, + ... + ], // response to a request for credential verification, optional +} +``` + +Server responds to a `{login}` packet with a `{ctrl}` message. The `params` of the message contains the id of the logged in user as `user`. The `token` contains an encrypted string which can be used for authentication. Expiration time of the token is passed as `expires`. + +#### `{sub}` + +The `{sub}` packet serves the following functions: + * creating a new topic + * subscribing user to an existing topic + * attaching session to a previously subscribed topic + * fetching topic data + +User creates a new group topic by sending `{sub}` packet with the `topic` field set to `new12321` (regular topic) or `nch12321` (channel) where `12321` denotes any string including an empty string. Server will create a topic and respond back to the session with the name of the newly created topic. + +User creates a new peer to peer topic by sending `{sub}` packet with `topic` set to peer's user ID. + +The user is always subscribed to and the session is attached to the newly created topic. + +If the user had no relationship with the topic, sending `{sub}` packet creates it. Subscribing means to establish a relationship between session's user and the topic where no relationship existed in the past. + +Joining (attaching to) a topic means for the session to start consuming content from the topic. Server automatically differentiates between subscribing and joining/attaching based on context: if the user had no prior relationship with the topic, the server subscribes the user then attaches the current session to the topic. If relationship existed, the server only attaches the session to the topic. When subscribing, the server checks user's access permissions against topic's access control list. It may grant immediate access, deny access, may generate a request for approval from topic managers. + +Server replies to the `{sub}` with a `{ctrl}`. + +The `{sub}` message may include a `get` and `set` fields which mirror `{get}` and `{set}` messages. If included, server will treat them as a subsequent `{set}` and `{get}` messages on the same topic. If the `get` is set, the reply may include `{meta}` and `{data}` messages. + + +```js +sub: { + id: "1a2b3", // string, client-provided message id, optional + topic: "me", // topic to be subscribed or attached to + bkg: true, // request to attach to topic is issued by an automated agent, server should delay sending + // presence notifications because the agent is expected to disconnect very quickly + // Object with topic initialisation data, new topics & new + // subscriptions only, mirrors {set} message + set: { + // New topic parameters, mirrors {set desc} + desc: { + defacs: { + auth: "JRWS", // string, default access for new authenticated subscribers + anon: "N" // string, default access for new anonymous (un-authenticated) + // subscribers + }, // Default access mode for the new topic + trusted: { ... }, // application-defined payload assigned by the system administration + public: { ... }, // application-defined payload to describe topic + private: { ... } // per-user private application-defined content + }, // object, optional + + // Subscription parameters, mirrors {set sub}.

It also serves two functions: +* leaving the topic without unsubscribing (`unsub=false`) +* unsubscribing (`unsub=true`) + +Server responds to `{leave}` with a `{ctrl}` packet. Leaving without unsubscribing affects just the current session. Leaving with unsubscribing will affect all user's sessions. + +```js +leave: { + id: "1a2b3", // string, client-provided message id, optional + topic: "grp1XUtEhjv6HND", // string, topic to leave, unsubscribe, or + // delete, required + unsub: true // boolean, leave and unsubscribe, optional, default: false +} +``` + +#### `{pub}` + +The message is used to distribute content to topic subscribers. + +```js +pub: { + id: "1a2b3", // string, client-provided message id, optional + topic: "grp1XUtEhjv6HND", // string, topic to publish to, required + noecho: false, // boolean, suppress echo (see below), optional + head: { key: "value", ... }, // set of string key-value pairs, optional + content: { ... } // object, application-defined content to publish + // to topic subscribers, required +} +``` + +Topic subscribers receive the `content` in the [`{data}`](#data) message. By default the originating session gets a copy of `{data}` like any other session currently attached to the topic. If for some reason the originating session does not want to receive the copy of the data it just published, set `noecho` to `true`. + +See [Format of Content](#format-of-content) for `content` format considerations. + +The following values are currently defined for the `head` field: + + * `attachments`: an array of paths indicating media attached to this message `["/v0/file/s/sJOD_tZDPz0.jpg"]`. + * `auto`: `true` when the message was sent automatically, i.e. by a chatbot or an auto-responder. + * `forwarded`: an indicator that the message is a forwarded message, a unique ID of the original message, `"grp1XUtEhjv6HND:123"`. + * `mentions`: an array of user IDs mentioned (`@alice`) in the message: `["usr1XUtEhjv6HND", "usr2il9suCbuko"]`. + * `mime`: MIME-type of the message content, `"text/x-drafty"`; a `null` or a missing value is interpreted as `"text/plain"`. + * `replace`: an indicator that the message is a correction/replacement for another message, a topic-unique ID of the message being updated/replaced, `":123"` + * `reply`: an indicator that the message is a reply to another message, a unique ID of the original message, `"grp1XUtEhjv6HND:123"`. + * `sender`: a user ID of the sender added by the server when the message is sent on behalf of another user, `"usr1XUtEhjv6HND"`. + * `thread`: an indicator that the message is a part of a conversation thread, a topic-unique ID of the first message in the thread, `":123"`; `thread` is intended for tagging a flat list of messages as opposite to creating a tree. + * `webrtc`: a string representing the state of the video call the message represents. Possible values: + * `"started"`: call has been initiated and being established + * `"accepted"`: call has been accepted and established + * `"finished"`: previously successfully established call has been ended + * `"missed"`: call timed out before getting established + * `"declined"`: call was hung up by the callee before getting established + * `"busy"`: the call was declined due to the callee being in another call. + * `"disconnected"`: call was terminated by the server for other reasons (e.g. due to an error) + * `webrtc-duration`: a number representing a video call duration (in milliseconds). + +Application-specific fields should start with an `x--`. Although the server does not enforce this rule yet, it may start doing so in the future. + +The unique message ID should be formed as `:` whenever possible, such as `"grp1XUtEhjv6HND:123"`. If the topic is omitted, i.e. `":123"`, it's assumed to be the current topic. + +#### `{get}` + +Query topic for metadata, such as description or a list of subscribers, or query message history. The requester must be [subscribed and attached](#sub) to the topic to receive the full response. Some limited `desc` and `sub` information is available without being attached. + +```js +get: { + id: "1a2b3", // string, client-provided message id, optional + topic: "grp1XUtEhjv6HND", // string, name of topic to request data from + what: "sub desc data del cred", // string, space-separated list of parameters to query; + // unknown values are ignored; required + + // Optional parameters for {get what="desc"} + desc: { + ims: "2015-10-06T18:07:30.038Z" // timestamp, "if modified since" - return + // public and private values only if at least one of them has been + // updated after the stated timestamp, optional + }, + + // Optional parameters for {get what="sub"} + sub: { + ims: "2015-10-06T18:07:30.038Z", // timestamp, "if modified since" - return + // public and private values only if at least one of them has been + // updated after the stated timestamp, optional + user: "usr2il9suCbuko", // string, return results for a single user, + // any topic other than 'me', optional + topic: "usr2il9suCbuko", // string, return results for a single topic, + // 'me' topic only, optional + limit: 20 // integer, limit the number of returned objects + }, + + // Optional parameters for {get what="data"} + data: { + since: 123, // integer, load messages with server-issued IDs greater or equal + // to this (inclusive/closed), optional + before: 321, // integer, load messages with server-issed sequential IDs less + // than this (exclusive/open), optional + limit: 20, // integer, limit the number of returned objects, default: 32, + // optional + }, + + // Optional parameters for {get what="del"} + del: { + since: 5, // integer, load deleted ranges with the delete transaction IDs greater + // or equal to this (inclusive/closed), optional + before: 12, // integer, load deleted ranges with the delete transaction IDs less + // than this (exclusive/open), optional + limit: 25, // integer, limit the number of returned objects, default: 32, + // optional + } +} +``` + +* `{get what="desc"}` + +Query topic description. Server responds with a `{meta}` message containing requested data. See `{meta}` for details. +If `ims` is specified and data has not been updated, the message will skip `trusted`, `public`, and `private` fields. + +Limited information is available without [attaching](#sub) to topic first. + +See [Trusted, Public, and Private Fields](#trusted-public-and-private-fields) for `trusted`, `private`, and `public` format considerations. + +* `{get what="sub"}` + +Get a list of subscribers. Server responds with a `{meta}` message containing a list of subscribers. See `{meta}` for details. +For `me` topic the request returns a list of user's subscriptions. If `ims` is specified and data has not been updated, +responds with a `{ctrl}` "not modified" message. + +Only user's own subscription is returned without [attaching](#sub) to topic first. + +* `{get what="tags"}` + +Query indexed tags. Server responds with a `{meta}` message containing an array of string tags. See `{meta}` and `fnd` topic for details. +Supported only for `me` and group topics. + +* `{get what="data"}` + +Query message history. Server sends `{data}` messages matching parameters provided in the `data` field of the query. +The `id` field of the data messages is not provided as it's common for data messages. When all `{data}` messages are transmitted, a `{ctrl}` message is sent. + +* `{get what="del"}` + +Query message deletion history. Server responds with a `{meta}` message containing a list of deleted message ranges. + +* `{get what="cred"}` + +Query [credentials](#credentail-validation). Server responds with a `{meta}` message containing an array of credentials. Supported for `me` topic only. + +* `{get what="aux"}` + +Query auxiliary topic data. Server responds with a `{meta}` message containing an object with auxiliary key-value pairs. + + +#### `{set}` + +Update topic metadata, delete messages or topic. The requester is generally expected to be [subscribed and attached](#sub) to the topic. Only `desc.private` and requester's `sub.mode` can be updated without attaching first. + +```js +set: { + id: "1a2b3", // string, client-provided message id, optional + topic: "grp1XUtEhjv6HND", // string, name of topic to update, required + + // Optional payload to update topic description + desc: { + defacs: { // new default access mode + auth: "JRWP", // access permissions for authenticated users + anon: "JRW" // access permissions for anonymous users + }, + trusted: { ... }, // application-defined payload assigned by the system administration + public: { ... }, // application-defined payload to describe topic + private: { ... } // per-user private application-defined content + }, + + // Optional payload to update subscription(s) + sub: { + user: "usr2il9suCbuko", // string, user affected by this request; + // default (empty) means current user + mode: "JRWP" // string, access mode change, either given ('user' + // is defined) or requested ('user' undefined) + }, // object, payload for what == "sub" + + // Optional update to tags (see fnd topic description) + tags: [ // array of strings + "email:alice@example.com", "tel:1234567890" + ], + + cred: { // Optional update to credentials. + meth: "email", // string, verification method, e.g. "email", "tel", "recaptcha", etc. + val: "alice@example.com", // string, credential to verify such as email or phone + resp: "178307", // string, verification response, optional + params: { ... } // parameters, specific to the verification method, optional + }, + + aux: { ... } // application-defined key-value pairs +} +``` + +#### `{del}` + +Delete messages, subscriptions, topics, users. + +```js +del: { + id: "1a2b3", // string, client-provided message id, optional + topic: "grp1XUtEhjv6HND", // string, topic affected, required for "topic", "sub", + // "msg" + what: "msg", // string, one of "topic", "sub", "msg", "user", "cred"; what + // to delete - the entire topic, a subscription, some or all messages, + // a user, a credential; optional, default: "msg" + hard: false, // boolean, request to hard-delete vs mark as deleted; in case of + // what="msg" delete for all users vs current user only; + // optional, default: false + delseq: [{low: 123, hi: 125}, {low: 156}], // array of ranges of message IDs + // to delete, inclusive-exclusive, i.e. [low, hi), optional + user: "usr2il9suCbuko" // string, user being deleted (what="user") or whose + // subscription is being deleted (what="sub"), optional + cred: { // credential to delete ('me' topic only). + meth: "email", // string, verification method, e.g. "email", "tel", etc. + val: "alice@example.com" // string, credential being deleted + } +} +``` + +`what="msg"` + +User can soft-delete `hard=false` (default) or hard-delete `hard=true` messages. Soft-deleting messages hides them from the requesting user but does not delete them from storage. An `R` permission is required to soft-delete messages. Hard-deleting messages deletes message content from storage (`head`, `content`) leaving a message stub. It affects all users. A `D` permission is needed to hard-delete messages. Messages can be deleted in bulk by specifying one or more message ID ranges in `delseq` parameter. Each delete operation is assigned a unique `delete ID`. The greatest `delete ID` is reported back in the `clear` of the `{meta}` message. + +`what="sub"` + +Deleting a subscription removes specified user from topic subscribers. It requires an `A` permission. A user cannot delete own subscription. A `{leave}` should be used instead. If the subscription is soft-deleted (default), it's marked as deleted without actually deleting a record from storage. + +`what="topic"` + +Deleting a topic deletes the topic including all subscriptions, and all messages. Only the owner can delete a topic. + +`what="user"` + +Deleting a user is a very heavy operation. Use caution. + +`what="cred"` + +Delete credential. Validated credentials and those with no attempts at validation are hard-deleted. Credentials with failed attempts at validation are soft-deleted which prevents their reuse by the same user. + + +#### `{note}` + +Client-generated ephemeral notification for forwarding to other clients currently attached to the topic, such as typing notifications or delivery receipts. The message is "fire and forget": not stored to disk per se and not acknowledged by the server. Messages deemed invalid are silently dropped. +The `{note.recv}` and `{note.read}` do alter persistent state on the server.

It implies `recv` as well. + * recv: a `{data}` message is received by the client software but may not yet seen by user. + +The `read` and `recv` notifications may optionally include `unread` value which is the total count of unread messages as determined by this client. The per-user `unread` count is maintained by the server: it's incremented when new `{data}` messages are sent to user and reset to the values reported by the `{note unread=...}` message. The `unread` value is never decremented by the server. The value is included in push notifications to be shown on a badge on iOS: +

+ + +### Server to Client Messages + +Messages to a session generated in response to a specific request contain an `id` field equal to the id of the +originating message. The `id` is not interpreted by the server. + +Most server to client messages have a `ts` field which is a timestamp when the message was generated by the server. + +#### `{data}` + +Content published in the topic. These messages are the only messages persisted in database; `{data}` messages are +broadcast to all topic subscribers with an `R` permission. + +```js +data: { + topic: "grp1XUtEhjv6HND", // string, topic which distributed this message, + // always present + from: "usr2il9suCbuko", // string, id of the user who published the + // message; could be missing if the message was + // generated by the server + head: { key: "value", ... }, // set of string key-value pairs, passed + // unchanged from {pub}, optional + ts: "2015-10-06T18:07:30.038Z", // string, timestamp + seq: 123, // integer, server-issued sequential ID + content: { ... } // object, application-defined content exactly as published + // by the user in the {pub} message +} +``` + +Data messages have a `seq` field which holds a sequential numeric ID generated by the server. The IDs are guaranteed to be unique within a topic. IDs start from 1 and sequentially increment with every successful [`{pub}`](#pub) message received by the topic. + +See [Format of Content](#format-of-content) for `content` format considerations. + +See [`{pub}`](#pub) message for the possible values of the `head` field. + + +#### `{ctrl}` + +Generic response indicating an error or a success condition.

+├── token/ # Token 认证 +├── anon/ # 匿名认证 +├── code/ # 验证码认证 +└── rest/ # REST 外部认证 +``` + +**认证接口定义**: + +```go +// server/auth/auth.go +type Authenticator interface { + // 初始化 + Init(jsonconf json.RawMessage, opts ...any) error + + // 认证检查 + Authenticate(secret []byte) (types.Uid, Level, time.Time, error) + + // 生成秘密值 + GenSecret(uid types.Uid, authLvl Level, expires time.Time) ([]byte, error) +} +``` + +**添加新认证方式步骤**: + +1. 在 `server/auth/` 下创建新目录,如 `oauth/` +2. 实现 `Authenticator` 接口 +3. 在 `main.go` 中导入: `_ "github.com/tinode/chat/server/auth/oauth"` +4. 在配置文件中添加相应配置 + +### 2. 数据库适配器 (server/db/) + +数据库层采用适配器模式: + +```go +// server/db/adapter.go +type Adapter interface { + // 连接管理 + Open(config json.RawMessage) error + Close() error + IsOpen() bool + + // 用户管理 + UserCreate(user *t.User) error + UserGet(uid t.Uid) (*t.User, error) + UserUpdate(uid t.Uid, update map[string]any) error + UserDelete(uid t.Uid, hard bool) error + + // 话题管理 + TopicCreate(topic

`server/hdl_websock.go` | WebSocket 连接处理 | +| `server/hub.go` | 会话和话题管理 | +| `pbx/model.proto` | gRPC 协议定义(如需同步支持) | + +--- + +## 场景一:添加新消息类型 + +### 示例:添加消息撤回功能 + +假设我们要添加一个 `{recall}` 消息类型,用于撤回已发送的消息。 + +### 步骤 1:定义消息结构 + +**文件**: `server/datamodel.go` + +```go +// 在文件末尾添加 + +// MsgClientRecall 是撤回消息的请求 {recall} +type MsgClientRecall struct { + // 消息 ID(用于响应匹配) + Id string `json:"id,omitempty"` + // 话题名称 + Topic string `json:"topic"` + // 要撤回的消息 ID 列表 + SeqList []int `json:"seq"` + // 是否硬删除(对所有人生效) + Hard bool `json:"hard,omitempty"` +} + +// MsgServerRecall 是撤回消息的响应 +type MsgServerRecall struct { + // 原请求 ID + Id string `json:"id,omitempty"` + // 话题名称 + Topic string `json:"topic,omitempty"` + // 已撤回的消息 ID 列表 + SeqList []int `json:"seq,omitempty"` + // 撤回时间 + Deleted *time.Time `json:"deleted,omitempty"` +} +``` + +### 步骤 2:添加到 ClientComMessage + +**文件**: `server/datamodel.go` + +```go +// ClientComMessage 是客户端消息的包装器 +type ClientComMessage struct { + Hi *MsgClientHi `json:"hi"` + Acc *MsgClientAcc `json:"acc"` + Login *MsgClientLogin `json:"login"` + Sub *MsgClientSub `json:"sub"` + Leave *MsgClientLeave `json:"leave"` + Pub *MsgClientPub `json:"pub"` + Get *MsgClientGet `json:"get"` + Set *MsgClientSet `json:"set"` + Del *MsgClientDel `json:"del"` + Note *MsgClientNote `json:"note"` + Recall *MsgClientRecall `json:"recall"` // ← 添加这一行 + + // ... 其他字段 +} +``` + +### 步骤 3:添加到 ServerComMessage + +**文件**: `server/datamodel.go` + +```go +// ServerComMessage 是服务器消息的包装器 +type ServerComMessage struct { + Ctrl *MsgServerCtrl `json:"ctrl,omitempty"` + Data *MsgServerData `json:"data,omitempty"` + Meta *MsgServerMeta `json:"meta,omitempty"` + Pres *MsgServerPres `json:"pres,omitempty"` + Info *MsgServerInfo `json:"info,omitempty"` + Recall *MsgServerRecall `json:"recall,omitempty"` // ← 添加这一行 + + // ... 其他字段 +} +``` + +### 步骤 4:实现消息处理器 + +**文件**: `server/session.go` + +```go +// 在文件末尾添加 + +// recall 处理消息撤回请求 +func (s *Session) recall(msg *ClientComMessage) { + // 1. 检查是否已认证 + if msg.AsUser == "" { + s.queueOut(ErrAuthRequiredReply(msg, msg.Timestamp)) + return + } + + // 2. 获取话题 + topic := msg.Original + t := globals.hub.topicGet(topic) + if t == nil { + s.queueOut(ErrTopicNotFoundReply(msg, msg.Timestamp)) + return + } + + // 3. 检查权限 + modeWant, modeGiven := t.getPerUserAcs(types.ParseUserId(msg.AsUser)) + if !(modeGiven & modeWant).IsWriter() { + s.queueOut(ErrPermissionDeniedReply(msg, msg.Timestamp)) + return + } + + // 4. 调用话题处理撤回 + t.clientMsg <- msg +} +``` + +### 步骤 5:注册消息路由 + +**文件**: `server/session.go` + +找到 `dispatch` 函数,在 switch 语句中添加新的 case: + +```go +func (s *Session) dispatch(msg *ClientComMessage) { + // ... 前面的代码保持不变 + + switch { + case msg.Pub != nil: + handler = checkVers(checkUser(s.publish)) + msg.Id = msg.Pub.Id + msg.Original = msg.Pub.Topic + + // ... 其他 case + + case msg.Recall != nil: // ← 添加这个 case + handler =

unknown message", s.sid) + return + } + + // ... 后续代码 +} +``` + +### 步骤 6:在 Topic 中实现业务逻辑 + +**文件**: `server/topic.go` + +```go +// 在 Topic 的消息处理循环中添加 +func (t *Topic) runLocal(hub *Hub) { + for { + select { + case msg := <-t.clientMsg: + switch { + case msg.Recall != nil: + t.handleRecall(msg) + // ... 其他消息类型 + } + + // ... 其他 case + } + } +} + +// handleRecall 处理消息撤回 +func (t *Topic) handleRecall(msg *ClientComMessage) { + // 1. 验证消息所有权 + uid := types.ParseUserId(msg.AsUser) + + // 2. 从数据库删除消息 + var deletedSeqs []int + for _, seq := range msg.Recall.SeqList { + // 检查是否是自己发送的消息 + if t.isMessageOwner(seq, uid) || msg.Recall.Hard { + err := store.Messages.Delete(t.name, seq, msg.Recall.Hard) + if err == nil { + deletedSeqs = append(deletedSeqs, seq) + } + } + } + + // 3. 更新

+如果需要 gRPC 客户端也支持,需要修改: + +**文件**: `pbx/model.proto` + +```protobuf +// 添加新的消息定义 +message ClientRecall { + string id = 1; + string topic = 2; + repeated int32 seq = 3; + bool hard = 4; +} + +message ServerRecall { + string id = 1; + string topic = 2; + repeated int32 seq = 3; + int64 deleted = 4; +} + +// 添加到 ClientMsg +message ClientMsg { + oneof Message { + // ... 现有字段 + ClientRecall recall = 14; // 使用新的字段号 + } + ClientExtra extra = 13; +} + +// 添加到 ServerMsg +message ServerMsg { + oneof Message { + // ... 现有字段 + ServerRecall recall = 6; + } +} +``` + +然后生成 Go 代码: + +```bash +# 在 pbx 目录执行 +protoc --go_out=plugins=grpc:. model.proto +``` + +**文件**: `server/pbconverter.go` + +添加序列化和反序列化函数: + +```go +func pbCliSerialize(msg *ClientComMessage) *pbx.ClientMsg { + // ... 现有代码 + + case msg.Recall != nil: + pkt.Message = &pbx.ClientMsg_Recall{ + Recall: &pbx.ClientRecall{ + Id: msg.Recall.Id, + Topic: msg.Recall.Topic, + Seq: msg.Recall.SeqList, + Hard: msg.Recall.Hard, + }, + } +} + +func pbCliDeserialize(pkt *pbx.ClientMsg) *ClientComMessage { + // ... 现有代码 + + if recall := pkt.GetRecall(); recall != nil { + msg.Recall = &MsgClientRecall{ + Id: recall.GetId(), + Topic: recall.GetTopic(), + SeqList: recall.GetSeq(), + Hard: recall.GetHard(), + } + } +} +``` + +### 步骤 8:编写单元测试 + +**文件**: `server/session_test.go` + +```go +func TestRecallMessage(t *testing.T) { + // 1. 创建测试会话 + sess := createTestSession() + defer sess.cleanUp(false) + + // 2. 发送登录 + sess.dispatchRaw([]byte(`{ + "login": { + "id": "login1", + "scheme": "basic", + "secret": "dXNlcjpwYXNz" + } + }`)) + + // 3. 订阅话题 + sess.dispatchRaw([]byte(`{ + "sub": { + "id": "sub1", + "topic": "test-topic" + } + }`)) + + // 4. 发送消息 + sess.dispatchRaw([]byte(`{ + "pub": { + "id": "pub1", + "topic": "test-topic",

验证或其他验证逻辑 + return token != "" +} +``` + +### 步骤 2:注册路由 + +**文件**: `server/http.go` + +```go +func setupHTTPHandlers() { + // ... 现有路由 + + // 添加管理后台 WebSocket 路由 + http.HandleFunc("/admin/channels", serveAdminWebSocket) +} +``` + +### 步骤 3:扩展 Session 结构 + +**文件**: `server/session.go` + +```go +type Session struct { + // ... 现有字段 + + // 是否为管理员会话 + isAdmin bool +} +``` + +### 步骤 4:添加管理员专用消息 + +可以在 dispatch 函数中添加管理员专用的消息处理: + +```go +func (s *Session) dispatch(msg *ClientComMessage) { + // 管理员专用消息检查 + if msg.AdminCmd != nil { + if !s.isAdmin { + s.queueOut(ErrPermissionDenied("", "", now)) + return + } + handler = s.handleAdminCommand + msg.Id = msg.AdminCmd.Id + } + + // ... 其他消息处理 +} +``` + +--- + +## 场景三:修改现有消息处理 + +### 示例:为 {pub} 消息添加过期时间 + +假设我们要为消息添加自动过期功能。 + +### 步骤 1:扩展消息结构 + +**文件**: `server/datamodel.go` + +```go +// MsgClientPub 是客户端发布消息的请求 +type MsgClientPub struct { + Id string `json:"id,omitempty"` + Topic string `json:"topic"` + NoEcho bool `json:"noecho,omitempty"` + Head map[string]any `json:"head,omitempty"` + Content any `json:"content"` + + // 新增:消息过期时间(秒) + ExpiresAfter int `json:"expires_after,omitempty"` +} +``` + +### 步骤 2:修改 Topic 处理逻辑 + +**文件**: `server/topic.go` + +```go +func (t *Topic) handlePublish(msg *ClientComMessage) { + // ... 现有逻辑 + + // 处理过期时间 + var expiresAt *time.Time + if msg.Pub.ExpiresAfter > 0 { + exp :=

return err +} +``` + +--- + +## 场景四:添加新的认证方式 + +### 示例:添加 OAuth 认证 + +### 步骤 1:实现认证处理器 + +**文件**: `server/auth/oauth.go` + +```go +package auth + +import ( + "context" + "encoding/json" + "net/http" + "net/url" + + "golang.org/x/oauth2" + "golang.org/x/oauth2/google" +) + +// OAuth 认证处理器 +type OAuthAuthenticator struct { + oauthConfig *oauth2.Config +} + +func NewOAuthAuthenticator(clientID,

err + } + defer resp.Body.Close() + + var userInfo struct { + Email string `json:"email"` + Name string `json:"name"` + } + json.NewDecoder(resp.Body).Decode(&userInfo) + + // 查找或创建用户 + uid := findOrCreateUserByEmail(userInfo.Email, userInfo.Name) + + return uid, nil, 0, nil +} +``` + +### 步骤 2:注册认证器 + +**文件**: `server/auth/auth.go` + +```go +func init() { + // 注册 OAuth 认证器 + Register("oauth", func(params map[string]any) (Authenticator, error) { + clientID, _ := params["client_id"].(string) + clientSecret, _ := params["client_secret"].(string) + redirectURL, _ := params["redirect_url"].(string) + return NewOAuthAuthenticator(clientID, clientSecret, redirectURL), nil + }) +} +``` + +### 步骤 3:配置文件支持 + +**文件**: `server/tinode.conf` + +```json +{ + "auth": { + "oauth": { + "enabled": true, + "client_id": "your-client-id", + "client_secret": "your-client-secret", + "redirect_url": "https://your-app.com/oauth/callback" + } + } +} +``` + +### 步骤 4:前端使用 + +```javascript +// 前端发送登录请求 +ws.send(JSON.stringify({ + login: { + id: "login1", + scheme: "oauth", + secret: "authorization_code_from_provider" + } +})); +``` + +--- + +## 测试指南 + +### 单元测试 + +```go +// server/session_test.go +func TestNewMessageType(t *testing.T) { + tests := []struct { + name string + input string + expected *ClientComMessage + }{ + { + name: "recall message", + input: `{"recall": {"id": "1", "topic": "test", "seq": [1, 2]}}`, + expected: &ClientComMessage{ + Recall: &MsgClientRecall{ + Id: "1", + Topic: "test", + SeqList: []int{1, 2}, + }, + }, + }, + } + + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + var msg ClientComMessage + err := json.Unmarshal([]byte(tt.input), &msg) + assert.NoError(t, err) + assert.Equal(t, tt.expected.Recall, msg.Recall) + }) + } +} +``` + +### 集成测试 + +```go +// server/integration_test.go +func TestWebSocketProtocol(t *testing.T) { + // 1. 启动测试服务器 + srv := startTestServer() + defer srv.Close() + + // 2. 连接 WebSocket + ws := connectWebSocket(t, srv.URL) + defer ws.Close() + + // 3. 测试消息流程 + testFullFlow(t, ws) +} + +func testFullFlow(t *testing.T, ws *websocket.Conn) { + // 发送 hi + sendAndExpect(t, ws, + `{"hi": {"id": "hi1", "ver": "0.22", "ua": "test"}}`, + func(resp map[string]any) { + assert.Equal(t, 200, int(resp["ctrl"].(map[string]any)["code"].(float64))) + }) + + // 发送 login + sendAndExpect(t, ws, + `{"login": {"id": "login1", "scheme": "basic", "secret": "dXNlcjpwYXNz"}}`, + func(resp map[string]any) { + assert.Equal(t, 200, int(resp["ctrl"].(map[string]any)["code"].(float64))) + }) +} +``` + +### 压力测试 + +```go +// server/benchmark_test.go +func BenchmarkMessageDispatch(b *testing.B) { + sess := createTestSession() + defer sess.cleanUp(false) + + raw := []byte(`{"pub": {"id": "1", "topic": "test", "content": "hello"}}`) + + b.ResetTimer() + for i := 0; i < b.N; i++ { + sess.dispatchRaw(raw) + } +} +``` + +--- + +## 调试技巧 + +### 1. 启用详细日志 + +```go +// 在 tinode.conf 中 +{ + "log_level": "debug", + "log_file": "/var/log/tinode/debug.log" +} +``` + +### 2. WebSocket 抓包 + +使用 Wireshark 或浏览器开发者工具: + +```javascript +// 浏览器控制台 +const ws = new WebSocket('ws://localhost:6060/v0/channels'); + +ws.onopen = () => { + console.log('Connected'); + ws.send(JSON.stringify({hi: {ver: "0.22", ua: "debug"}})); +}; + +ws.onmessage = (e) => { + console.log('Received:', JSON.parse(e.data)); +}; + +// 发送测试消息 +ws.send(JSON.stringify({ + recall: {id: "1", topic: "test", seq: [1]} +})); +``` + +### 3. 使用 wscat 工具 + +```bash +# 安装 +npm install -g wscat + +# 连接 +wscat -c ws://localhost:6060/v0/channels + +# 发送消息 +> {"hi": {"ver": "0.22", "ua": "wscat"}} +< {"ctrl":{"code":200,"text":"ok",...}} + +> {"recall": {"id": "1", "topic": "test", "seq": [1]}} +< {"ctrl":{"code":200,"text":"ok",...}} +``` + +### 4. 断点调试 + +在 VSCode 中设置断点: + +```go +// 在 dispatchRaw 函数设置断点 +func (s *Session) dispatchRaw(raw []byte) { + logs.Debug.Printf("Received: %s", string(raw)) // 添加日志 + // ... +} +``` + +--- + +## 最佳实践 + +### 1. 向后兼容 + +添加新字段时使用 `omitempty`: + +```go +type MsgClientPub struct { + // ... 现有字段 + ExpiresAfter int `json:"expires_after,omitempty"` // 可选字段 +} +``` + +### 2. 版本检查 + +对于需要特定版本的功能: + +```go +func (s *Session) recall(msg *ClientComMessage) { + if s.ver < minVersionForRecall { + s.queueOut(ErrUnsupportedVersion(msg.Id, msg.Original, msg.Timestamp)) + return + } + // ... +} +``` + +### 3. 权限控制 + +始终检查用户权限: + +```go +func (s *Session) recall(msg *ClientComMessage) { + // 检查用户是否已认证 + if msg.AsUser == "" { + s.queueOut(ErrAuthRequiredReply(msg, msg.Timestamp)) + return + } + + // 检查话题权限 + modeWant, modeGiven := t.getPerUserAcs(uid) + if !(modeGiven & modeWant).IsWriter() { + s.queueOut(ErrPermissionDeniedReply(msg, msg.Timestamp)) + return + } +} +``` + +### 4. 错误处理 + +提供有意义的错误信息: + +```go +func (s *Session) recall(msg *ClientComMessage) { + if len(msg.Recall.SeqList) == 0 { + s.queueOut(&ServerComMessage{ + Ctrl: &MsgServerCtrl{ + Id: msg.Id, + Code: 400, + Text: "No message IDs provided", + Topic: msg.Original, + }, + }) + return + } +} +``` + +### 5. 单元测试覆盖 + +确保新功能有测试覆盖: + +```go +func TestRecallValidation(t *testing.T) { + tests := []struct { + name string + msg *MsgClientRecall + wantErr bool + }{ + {"empty seq list", &MsgClientRecall{SeqList: []int{}}, true}, + {"valid seq list", &MsgClientRecall{SeqList: []int{1, 2}}, false}, + } + + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + err := validateRecallMessage(tt.msg) + if tt.wantErr { + assert.Error(t, err) + } else { + assert.NoError(t, err) + } + }) + } +} +``` + +--- + +## 常见问题 + +### Q1: 如何处理大消息? + +使用消息分片或文件上传: + +```go +// 大消息应该使用文件上传 +if len(content) > maxInlineMessageSize { + // 上传到文件服务 + url, err := uploadFile(content) + // 发送文件引用 + sendFileReference(url) +} +``` + +### Q2: 如何支持消息压缩? + +启用 WebSocket 压缩: + +```go +var upgrader = websocket.Upgrader{ + EnableCompression: true, // 启用压缩 +} +``` + +### Q3: 如何处理客户端断线重连? + +使用会话恢复: + +```javascript +// 客户端重连时提供之前的 sid +ws.send(JSON.stringify({ + hi: { + ver: "0.22", + ua: "client", + device_id: "unique-device-id" // 用于恢复会话 + } +})); +``` + +### Q4: 如何支持集群部署? + +使用 Hub 的集群功能: + +```go +// 配置集群 +{ + "cluster": { + "enabled": true, + "nodes": ["node1:6060", "node2:6060"] + } +} +``` + +--- + +## 总结 + +扩展 WebSocket 协议的核心步骤: + +1. **定义数据结构** - 在 `datamodel.go` 中添加 +2. **实现处理逻辑** - 在 `session.go` 中添加处理器 +3. **注册消息路由** - 在 `dispatch` 函数中注册 +4.

前后端接口文档](/Users/superysh/im/chat-0.25.3/docs/IM-WS-API-CN.md:1)、Tinode 原生 [API 文档](/Users/superysh/im/chat-0.25.3/docs/API.md:1)、[代码通读指南](/Users/superysh/im/chat-0.25.3/docs/CODE-WALKTHROUGH.md:1) 与当前 Go 代码整理,作为后续后端开发依据。目标是保持 Tinode 现有协议和代码风格,默认全部前后端业务通信走 WebSocket,尽量复用现有 Topic、Session、Store、ACL、Drafty、文件上传和 JSON 扩展字段,减少侵入式改动。 + +## 一、目标与原则 + +### 1.1 建设目标 + +| 目标 | 说明 | +|---|---| +| 保持 Tinode 协议兼容 | 继续使用 `{hi}`、`{login}`、`{sub}`、`{pub}`、`{get}`、`{set}`、`{del}`、`{note}` | +| 默认 WebSocket 通信 | 客户端统一连接 `/v0/channels`,服务端通过现有 `Session -> Hub -> Topic` 消息链路处理 | +| 小步扩展业务能力 | 好友、群聊、文件、收藏、通话优先映射到 Tinode 原生能力 | +| 小改动 | 第一阶段不新增数据库表,不改核心消息协议字段语义 | +| 可测试 | 所有新增逻辑必须补充 Go 单元测试,MySQL 持久化改动必须补 adapter 集成测试 | + +### 1.2 设计原则 + +1. 原生字段优先:用户资料使用 `users.public`,用户私有设置使用 `subscriptions.private` 或 `users.private`,群业务配置使用 `topics.aux`。 +2. 扩展字段隔离:所有产品扩展字段统一使用 `x-im-*`,避免污染 Tinode 原生字段。 +3. 权限使用 ACL:管理员、禁言、踢人、群主转让优先通过 Tinode `modewant/modegiven` 权限实现。 +4. 持久消息走 `{pub}`:文本、图片、文件、语音、名片、转发、收藏、系统通知都以持久化消息建模。 +5. 临时状态走 `{note}`:输入中、录音中、已收、已读、通话信令使用临时通知,不落库。 +6. 数据库变更后置:只有搜索、积分、签到这类确实需要索引或事务的能力才新增业务表。 + +## 二、系统设计 + +### 2.1 总体架构 + +```text +Client + | + | WebSocket JSON frames + v +server/hdl_websock.go + | + v +Session.dispatchRaw / Session.dispatch + | + +-- hi/login/acc: Session 内处理 + | + +-- sub/get/set/del/pub/note + | + v + Hub + | + v + Topic.runLocal + | + +-- handleSubscription + +-- handleClientMsg + +-- handleMeta + +-- handleServerMsg + | + v + store.* interfaces + | + v + server/db/mysql adapter +``` + +本方案不新增独立 HTTP 业务 API。除 Tinode 已有大文件上传 `/v0/file/u/` 与下载 `/v0/file/s/` 外,业务请求全部复用 WebSocket 消息包。 + +### 2.2 功能映射 + +| 原型能力 | 后端实现 | +|---|---| +| 登录、注册、忘记密码 | 复用 `{hi}`、`{login}`、`{acc}`、`basic/token/code/rest` auth | +| 私聊

登录、私聊、群聊、消息、附件、回执、基础好友、群管理、收藏、通话信令、举报反馈 | 不新增表 | +| Phase 2 | 聊天记录关键词搜索、按文件类型搜索、话题积分、签到幂等、运营后台检索 | 新增少量 `im_*` 业务表 | +| Phase 3 | 反诈风控、内容审核、推荐排序、全文搜索优化 MVP | 复用 `messages/topics/topictags` 与 `im_message_index`,MySQL schema `119` 新增全文索引 | + +当前 Phase 1、Phase 2 与 Phase 3 MVP 已按小改动路线接入。更复杂的风控模型、人工审核工作台、离线推荐服务和独立搜索引擎仍作为后续演进,不影响现有 WebSocket 对接。 + +## 三、代码结构设计 + +### 3.1 现有代码复用点 + +| 文件/模块 | 复用方式 | +|---|---| +| [server/hdl_websock.go](/Users/superysh/im/chat-0.25.3/server/hdl_websock.go:117) | 保持 WebSocket 入口不变 | +|

新增测试时继续使用 gomock | + +### 3.2 建议新增文件 + +第一阶段新增文件控制在少量 helper 与测试文件: + +| 文件 | 作用 | +|---|---| +| `server/imext.go` | 定义 `x-im-*` 常量、消息类型枚举、Drafty/JSON 解析辅助方法 | +| `server/imext_test.go` | 测试扩展字段解析、消息类型判断、搜索文本提取 | +| `server/im_policy.go` | 封装业务策略:群禁言、进群验证、拉黑、反诈标记判断 | +| `server/im_policy_test.go` | 业务策略单元测试 | + +第二阶段如需数据库索引,再新增: + +| 文件 | 作用 | +|---|---| +| `server/store/imindex.go` | 定义业务索引查询接口,避免把搜索逻辑塞进 Topic | +| `server/db/mysql/imindex.go` | MySQL 业务索引表读写实现 | +| `server/db/mysql/imindex_test.go` | MySQL 业务索引集成测试 | + +### 3.3 最小代码变更点 + +#### 3.3.1 扩展字段解析 + +新增 `server/imext.go`,只做轻量解析,不改变原有消息结构语义。 + +```go +const ( + imHeadType = "x-im-type" + imHeadClientMID = "x-im-client-mid" + imHeadAntiFraud = "x-im-anti-fraud" +) + +type imMessageType string + +const ( + imMsgText imMessageType = "text" + imMsgImage imMessageType = "image" + imMsgAudio imMessageType = "audio" + imMsgVideo imMessageType = "video" + imMsgFile imMessageType = "file" + imMsgCard imMessageType = "card" + imMsgFavorite imMessageType = "favorite" + imMsgForwardBundle imMessageType = "forward-bundle" + imMsgGroupJoinApply imMessageType = "group-join-apply" + imMsgGroupAnnouncement imMessageType = "group-announcement" + imMsgCall imMessageType = "call" + imMsgTopicShare imMessageType = "topic-share" + imMsgSystemNotice imMessageType = "system-notice" + imMsgReport imMessageType = "report" + imMsgFeedback imMessageType = "feedback" + imMsgCheckin imMessageType = "checkin" +) +``` + +解析 helper 建议只返回类型与布尔值,不在业务层直接类型断言散落代码: + +```go +func imGetMessageType(head map[string]any) imMessageType +func imIsAttachmentType(tp imMessageType) bool +func imExtractSearchText(head map[string]any, content any) string +func imValidateCallPayload(payload json.RawMessage) error +``` + +#### 3.3.2 查询扩展字段 + +当前 `MsgGetQuery` 没有 `x-im-search` 或 `x-im-filter` 字段,Go 反序列化会忽略未知字段。若第一阶段需要服务端处理聊天记录搜索,需要在 [server/datamodel.go](/Users/superysh/im/chat-0.25.3/server/datamodel.go:40) 显式增加字段: + +```go +type MsgGetQuery struct { + What string `json:"what"` + + Desc *MsgGetOpts `json:"desc,omitempty"` + Sub *MsgGetOpts `json:"sub,omitempty"` + Data *MsgGetOpts `json:"data,omitempty"` + Del *MsgGetOpts `json:"del,omitempty"` + + XIMSearch *MsgSearchOpts `json:"x-im-search,omitempty"` + XIMFilter *MsgFilterOpts `json:"x-im-filter,omitempty"` +} + +type MsgSearchOpts struct { + Keyword string `json:"keyword,omitempty"` + Types []string `json:"types,omitempty"` +} + +type MsgFilterOpts struct { + Types []string `json:"types,omitempty"` + Keyword string `json:"keyword,omitempty"` +} +``` + +第一阶段可以先不实现数据库索引,`Topic.replyGetData` 仍按 `data.limit` 拉取消息,再在内存里用 `imGetMessageType` 和 `imExtractSearchText` 做轻量过滤。第二阶段再替换为索引表查询。 + +#### 3.3.3 群禁言与拉黑策略 + +Tinode ACL 已支持写权限控制。业务层只需约定: + +| 场景 | 实现 | +|---|---| +| 群禁言成员 | 将目标用户 `mode` 设置为不含 `W` 的完整权限,如 `JRP`;同时维护 `aux.x-im-group.mutedUsers` | +| 解除群禁言 | 将目标用户 `mode` 设置为含 `W` 的完整权限,如 `JRWP` 或 `JRWPS`;同时清理 `aux.x-im-group.mutedUsers` | +| 拉黑好友 | 当前用户 `desc.private.x-im-blocked=true`,同时可调整对方 P2P 权限 | +| 群全员禁言 | `aux.x-im-group.muteAll=true`,发送消息时后端策略拒绝普通成员 | +| 单成员业务禁言 | `aux.x-im-group.mutedUsers`,发送消息时后端策略拒绝列表中的普通成员 | +| 群文件上传限制 | `aux.x-im-group.allowMemberFileUpload=false`,普通成员不能发送附件类消息 | +| 仅管理员邀请 | `aux.x-im-group.onlyAdminInvite=true`,非管理员不能邀请或重新邀请成员 | + +群级业务策略是 Tinode 原生 ACL 不能一次表达的约束,在 `Topic.handlePubBroadcast` 与 `Topic.anotherUserSub` 进入持久化前做小的策略检查: + +```go +if err := imCanPublish(t, asUid, msg); err != nil { + msg.sess.queueOut(ErrPermissionDeniedReply(msg, msg.Timestamp)) + return +} +``` + +`imCanPublish` 与 `imCanInvite` 只读取 `t.aux` 与 `t.perUser`,不访问数据库,避免扩大影响面。 + +#### 3.3.4 收藏 + +收藏不新增接口,不新增表。客户端向 `slf` 发送 `x-im-type="favorite"` 消息即可。 + +后端只需保证: + +1. `slf` topic 可正常创建和订阅。 +2. 收藏消息里的附件 URL 被写入 `extra.attachments`,复用文件 GC 引用计数。 +3. 收藏列表通过 `{sub topic="slf" get.what="data"}` 返回。 + +#### 3.3.5 话题 + +话题用频道建模: + +1. 发布话题:`{sub topic="nch"}` 创建 channel topic。 +2. 话题详情:读取 `desc.public.x-im-topic`。 +3. 参与话题:订阅 `chnXXX`。 +4. 评论:根据业务授予 `W` 权限后使用 `{pub}`。 + +第一阶段不做积分扣减时,不需要新增表。第二阶段接入积分时增加 `im_user_points`。 + +### 3.4 不建议改动的地方 + +| 模块 | 原因 | +|---|---| +| WebSocket handler | 入口稳定,不应新增业务分支 | +| Hub 路由模型 | 现有 channel/goroutine 模型清晰,业务应落在 Topic/Store | +| 原生消息字段命名 | 客户端 SDK 与文档依赖现有字段 | +| Adapter 核心接口 | 第一阶段避免给所有数据库后端增加方法 | +| gRPC converter | 本项目默认 WS,不做 gRPC 扩展 | + +## 四、数据库设计与变更 + +### 4.1 当前可复用字段 + +现有 MySQL schema 已经覆盖多数业务扩展需求: + +| 表 | 字段 | 用途 | +|---|---|---| +| `users` | `public` | 昵称、头像、性别、生日、地区、个性签名 | +| `users` | `tags` + `usertags` | 用户查找、手机号/用户名发现 | +| `topics` | `public` | 群资料、话题资料、频道封面 | +| `topics` | `aux` | 群公告、进群验证、群设置、全员禁言 | +| `subscriptions` | `private` | 备注、置顶、免打扰、拉黑、草稿 | +| `messages` | `head` | `x-im-type`、附件类型、引用、转发、@ | +| `messages` | `content` | Drafty 或业务 JSON 内容 | +| `fileuploads` | 全表 | 上传文件记录 | +| `filemsglinks` | 全表 | 文件与消息/topic/user 绑定,防止 GC | +| `kvmeta` | 全表 | 小型持久缓存,已有 `PCache` 封装 | + +### 4.2 Phase 1 数据库变更 + +Phase 1 不新增表、不新增字段。 + +原因: + +1. 用户资料、群资料、群设置、收藏、举报、反馈都可用 JSON 字段或消息承载。 +2. 图片、文件、语音已经有 `fileuploads` 与 `filemsglinks`。 +3. 消息查询先复用 `messages(topic, seqid)` 分页。 +4. 小改动优先,先保证 WebSocket 主流程稳定。 + +### 4.3 Phase 2 数据库变更 + +聊天记录搜索、话题积分、签到等功能进入后端强一致实现时新增业务表,表名统一 `im_` 前缀,避免与 Tinode 原生表混淆。当前 MySQL adapter 已实现 `im_message_index`、`im_user_points`、`im_user_daily_events`,数据库版本为 `118`。 + +#### 4.3.1 消息业务索引表 + +用途:支持按消息类型、关键词、附件维度查询,避免频繁扫描 `messages.content` JSON。 + +```sql +CREATE TABLE im_message_index( + id INT NOT NULL, + createdat DATETIME(3) NOT NULL, + updatedat DATETIME(3) NOT NULL, + topic CHAR(25) NOT NULL, + seqid INT NOT NULL, + fromuid BIGINT NOT NULL, + msgtype VARCHAR(32) NOT NULL, + search_text TEXT, + attachment_count INT NOT NULL DEFAULT 0, + deletedat DATETIME(3), + + PRIMARY KEY(id), + FOREIGN KEY(id) REFERENCES messages(id) ON DELETE CASCADE, + UNIQUE INDEX im_message_index_topic_seqid(topic, seqid), + INDEX im_message_index_topic_type_seq(topic, msgtype, seqid), + INDEX im_message_index_topic_createdat(topic, createdat), + FOREIGN KEY(topic) REFERENCES topics(name) ON DELETE CASCADE +); +``` + +说明:`id` 与 Tinode 现有 `messages.id` 保持一致使用 `INT`。中文全文检索初期使用 `LIKE`,MySQL `FULLTEXT` 是否启用 `ngram` parser 作为后续部署决策,不作为第一版强依赖。 + +#### 4.3.2 用户积分表 + +用途:话题发布积分扣减、签到积分发放。 + +```sql +CREATE TABLE im_user_points( + userid BIGINT NOT NULL, + createdat DATETIME(3) NOT NULL, + updatedat DATETIME(3) NOT NULL, + balance BIGINT NOT NULL DEFAULT 0, + frozen BIGINT NOT NULL DEFAULT 0, + + PRIMARY KEY(userid), + FOREIGN KEY(userid) REFERENCES users(id) ON DELETE CASCADE +); +``` + +#### 4.3.3 用户每日事件表 + +用途:签到幂等、每日任务、青少年模式时长限制等按日事件。 + +```sql +CREATE TABLE im_user_daily_events( + id BIGINT NOT NULL AUTO_INCREMENT, + createdat DATETIME(3) NOT NULL, + userid BIGINT NOT NULL, + event_date DATE NOT NULL, + event_type VARCHAR(32) NOT NULL, + payload JSON, + + PRIMARY KEY(id), + UNIQUE INDEX im_user_daily_events_user_date_type(userid, event_date, event_type), + FOREIGN KEY(userid) REFERENCES users(id) ON DELETE CASCADE +); +``` + +### 4.4 MySQL 迁移方式 + +Phase 2/3 按现有 MySQL adapter 风格升级。当前 MySQL adapter 已从 `116` 升级到 `119`,其中 `117` 新增 `im_message_index`,`118` 新增 `im_user_points` 与 `im_user_daily_events`,`119` 为 `im_message_index.search_text` 增加全文索引: + +1. [server/db/mysql/adapter.go](/Users/superysh/im/chat-0.25.3/server/db/mysql/adapter.go:44) 中 `adpVersion` 已更新为 `119`。 +2. `CreateDb` 的建表流程已加入三张 `im_*` 表,并在 `im_message_index` 上创建 `FULLTEXT INDEX im_message_index_search_text(search_text)`。 +3. `UpgradeDb` 已增加 `116 -> 117`、`117 -> 118` 与 `118 -> 119` 迁移块。 +4. 升级旧库到 `117` 时会扫描历史 `messages` 与 `filemsglinks` 回填索引,避免历史消息搜索缺失。 +5. 升级旧库到 `118` 时创建积分表和每日事件表。 +6. 升级旧库到 `119` 时通过 `ALTER TABLE im_message_index ADD FULLTEXT INDEX im_message_index_search_text(search_text)` 优化全文搜索。 +7. 迁移成功后通过 `bumpVersion(a, 119)` 更新 `kvmeta.version`。 +8. schema 文档 [server/db/mysql/schema.sql](/Users/superysh/im/chat-0.25.3/server/db/mysql/schema.sql:1) 已同步。 +9. MySQL adapter 集成测试已覆盖索引保存、搜索、全文索引存在性、推荐排序、软删除过滤、积分增扣和每日事件幂等。 + +不建议在第一阶段修改 `adapter.Adapter` 总接口,因为这会要求 PostgreSQL、MongoDB、RethinkDB 同步实现,改动面会变大。业务索引可以在第二阶段单独设计 `imstore` 接口,再按实际支持的数据库接入。 + +## 五、核心业务设计 + +### 5.1 登录注册与资料 + +使用现有认证模块: + +| 功能 | 实现 | +|---|---| +| 手机号密码登录 | `basic` 或 `rest` 认证 | +| Token 登录 | `token` 认证 | +| 验证码 | `code` 临时认证或 credential validator | +| 忘记密码 | `{login scheme="reset"}` | +| 实名认证 | `me.desc.private.x-im-realname` 保存申请,审核通过后 root 写 `trusted.verified=true` | + +代码改动:无核心改动。若对接外部账号系统,优先配置 `auth/rest`,避免改 `auth/basic`。 + +### 5.2 好友关系 + +P2P topic 即好友/联系人关系。添加好友通过 `{sub topic="usrXXX"}`,是否需要审批由 ACL 决定。 + +建议规则: + +| 状态 | ACL/字段 | +|---|---| +| 申请中 | `private.x-im-applyStatus="pending"`,ACL 仍记录当前 `want/given` | +| 已同意 | `private.x-im-applyStatus="accepted"`,双方 P2P 权限满足可聊条件 | +| 已拒绝/过期 | `private.x-im-applyStatus="rejected/expired"`,前端从 `me.sub.private` 过滤 | +| 已好友 | 双方 P2P 权限满足 `JRWPA` | +| 已拉黑 | 当前用户 `private.x-im-blocked=true`,必要时移除对方 `W` | +| 已删除 | `{leave unsub=true}` | + +### 5.3 群聊与群权限 + +复用 Tinode group topic: + +| 群角色 | Tinode 权限 | +|---|---| +| 群主 | `O` | +| 管理员 | `A/S/D` | +| 普通成员 | `J/R/W/P` | +| 禁言成员 | 移除 `W` | +| 被踢成员 | 删除订阅 | + +群设置统一写 `topics.aux.x-im-group`。前端展示用 `get what="desc sub aux"` 获取。 + +进群审批使用已有 subscriptions 表表达状态,不新增表:开启 `aux.x-im-group.joinApproval=true` 且群默认 `defacs.auth` 不含 `J` 时,申请者 `{sub set.sub.mode="JRWPS"}` 会创建 `want=JRWPS/given=N` 的待审批订阅,并保存 `private.x-im-joinApplyText` 与 `private.x-im-joinStatus="pending"`。管理员 `{get what="sub"}` 可看到待审批用户及其 private;通过时 `{set sub user=... mode="JRWPS"}` 自动把状态更新为 `accepted`,拒绝时 `{set sub user=... mode="N"}` 自动更新为 `rejected`。 + +### 5.4 消息与附件 + +所有消息仍由 `Topic.handlePubBroadcast` 保存为 `messages`: + +1. 文本、表情、@ 使用 Drafty。 +2. 图片、文件、语音、视频先上传文件,再发送 Drafty entity。 +3. `extra.attachments` 必填,复用 `store.Messages.Save` 中的附件绑定逻辑。 +4. `head.x-im-client-mid` 用于前端本地发送状态关联。 +5. `head.x-im-type` 用于客户端渲染和后续索引。 + +### 5.5 收藏 + +收藏使用 `slf` topic,不新增接口: + +| 操作 | 实现 | +|---|---| +| 收藏消息 | `{pub topic="slf" head.x-im-type="favorite"}` | +| 查看收藏 | `{sub topic="slf" get.what="data"}` | +| 删除收藏 | `{del topic="slf" what="msg"}` | +| 分享收藏 | 普通转发 `{pub}` | + +### 5.6 通话 + +通话信令复用 `{note what="call"}`: + +| 事件 | `note.event` | +|---|---| +| 已振铃 | `ringing` | +| 接受通话 | `accept` | +| SDP offer | `offer` | +| SDP answer | `answer` | +| ICE 候选 | `ice-candidate` | +| 拒绝/挂断 | `hang-up` | + +通话结束后发送持久化 `{pub}`,`head.webrtc` 与 `head.webrtc-duration` 使用 Tinode 原生字段。 + +### 5.7 话题 + +话题使用 channel topic: + +| 操作 | 实现 | +|---|---| +| 发布话题 | `{sub topic="nch"}` | +| 话题列表 | `fnd` 搜索 `topic` tags | +| 话题详情 | `{sub topic="chnXXX" get.what="desc data aux"}` | +| 参与话题 | 订阅 `chnXXX` | +| 转发帖子 | `{pub head.x-im-type="topic-share"}` | + +积分能力进入 Phase 2 后,通过 `im_user_points` 做事务扣减;当前签到已通过 `{pub topic="slf" head.x-im-type="checkin"}` 接入 `im_user_daily_events` 与 `im_user_points`,首次签到固定发放 `5` 积分,重复签到返回 `304 no action`。话题发布已通过 `{sub topic="nch"}` 接入 `public.x-im-topic.pointsCost`,MySQL 后端在同一事务中创建频道 topic、作者订阅并扣减积分,余额不足返回 `422 policy violation`。 + +### 5.8 举报、反馈与安全 + +举报和反馈向 `sys` topic 发送持久化消息。root/admin 后台订阅 `sys` 处理。 + +反诈与内容审核 Phase 3 MVP 已在发布链路内置轻量规则:`Topic.handlePubBroadcast` 保存消息前调用 `imReviewPubMessage`,命中疑似转账、验证码、外链、违禁词等关键词时追加 `head.x-im-anti-fraud=true`、`head.x-im-risk-level` 与 `head.x-im-moderation`。当前策略只标记不拦截,避免误伤聊天主流程;复杂风控评分、人工审核队列、模型服务可在后续通过相同 `head` 字段向前端兼容扩展。 + +### 5.9 推荐排序与搜索优化 + +话题推荐仍复用 Tinode `fnd` topic,避免新增 HTTP 接口或修改通用 adapter 接口。前端发送 `{get topic="fnd" what="sub" x-im-recommend={...}}`,`topic.go` 在 plugin find 未返回结果时检测 MySQL adapter 是否实现 `FindRecommendedTopics`,再按关键词、类型标签、业务标签、订阅数和活跃时间排序返回。 + +聊天记录全文搜索继续走 `im_message_index`。MySQL schema `119` 在 `search_text` 上增加 `FULLTEXT` 索引,查询条件使用 `MATCH ...

分析日期:2026-08-09 +> 分析对象:`chat-0.25.3` 当前工作区源码 +> 需求依据:[IM-产品原型需求文档](./IM-产品原型需求文档.md) +> 报告范围:服务端能力、数据模型、协议/API、安全、实施计划和验收建议 + +## 1. 报告结论 + +当前项目是一个以 Tinode 为核心的 Go 即时通讯服务端,已经具备稳定的实时通信底座:账号登录、单聊、群聊、订阅与访问控制、消息收发、已读/送达回执、输入状态、消息删除、文件上传、推送、点对点 WebRTC 信令,以及可扩展的 gRPC 插件机制。 + +原型中的基础聊天能力不需要推倒重做,建议继续复用现有 Topic、Subscription、Message 和 Session 模型。在此基础上增加产品业务层,负责好友关系、群治理、内容检索、企业组织、会议/日报/月报、实名认证、青少年模式、举报与安全审计等业务。 + +本次分析得到以下关键结论: + +1. **现有服务端可以承担实时通信内核,但不能直接满足完整产品需求。** 当前代码主要解决消息路由、会话和 ACL,不包含完整的社交关系、企业协同和安全治理领域模型。 +2. **应将“实时消息能力”和“产品业务能力”分层。** 聊天消息继续走 WebSocket;需要事务、查询、审批和管理的业务走 HTTP API;状态变化通过结构化系统消息回推 WebSocket。 +3. **必须先确定企业租户模式。** 当前 User、Topic、Subscription、Message 和 FileDef 均没有 `tenant_id`。如果多个企业共用一套数据库,租户隔离必须作为所有功能之前的基础改造。 +4. **消息幂等和文件授权是上线前必须修复的基础问题。** 发布消息处仍有“重复消息 ID 检查”的 TODO;文件下载只校验登录身份,没有验证用户是否有权访问对应消息或话题。 +5. **仓库部分旧文档与当前源码存在漂移。** 旧文档提到的 `x-im-*` 扩展、`im_*` 业务表、数据库版本 119 和 `tools/wsmock`,在当前源码中均未发现。本报告分析时各数据库适配器版本为 116;多租户第一阶段已把 MySQL 提升到 118,其他适配器仍为 116。本报告以可执行源码为准,不把文档设想视为已实现能力。 + +建议按“基础安全与协议 → 好友和群治理 → 搜索与文件 → 通话与设置 → 企业工作台”的顺序实施。若团队和测试资源稳定,完整服务端改造建议拆成 4 个产品阶段、6 至 9 个迭代交付。 + +## 2. 分析范围与判定口径 + +### 2.1 需求范围 + +本报告覆盖原型文档的 11 个功能域: + +1. 账号注册、登录与身份安全; +2. 消息首页、全局导航与系统通知; +3. 单聊会话、会话建立与消息状态; +4. 消息输入、媒体内容与消息操作; +5. 通讯录、好友关系与黑名单; +6. 群聊创建、资料维护与成员治理; +7. 文件下载、收藏管理与聊天记录检索; +8. 实时语音与视频通话; +9. 企业工作台与办公协同; +10. 个人资料、通用设置、隐私与青少年模式; +11. 反诈安全、举报与意见反馈。 + +### 2.2 能力分类 + +文中的需求按以下四类判定: + +| 分类 | 含义 | 处理方式 | +| --- | --- | --- | +| 已支持 | 当前代码已有可用服务端能力 |

以串行事件循环处理同一话题内的状态和消息,适合维持顺序号、订阅状态和广播一致性。扩展时不应在 Topic 事件循环中执行耗时的远程 RPC、全文搜索或复杂审批事务,否则会阻塞该话题的全部消息。 + +### 3.2 已有能力清单 + +| 能力 | 当前实现 | 主要源码位置 | 复用判断 | +| --- | --- | --- | --- | +| 账号创建与登录 |

当前消息表只对 `(topic, seqid)` 建唯一索引,没有消息类型索引、客户端消息 ID 唯一索引或全文检索索引。分析基线中各适配器均为 schema 116;当前 MySQL 已因租户主表升级到 118,PostgreSQL、MongoDB、RethinkDB 仍为 116。 + +### 3.4 当前主要缺口 + +1. `MsgGetQuery` 只支持 desc、sub、data、del,消息查询只有序号范围和数量,没有关键词、媒体类型、发送人、时间区间等检索条件。 +2. 发布消息时没有客户端消息幂等校验,`server/session.go:691` 仍保留重复消息 ID 检查 TODO。 +3. 当前群成员模型能表达 ACL,但不能完整表达申请加入、审批记录、过期状态和审批理由。直接用 `ModeGiven` 表示待审批会与当前订阅逻辑冲突。 +4. 当前群“静音”更接近通知/Presence 控制,不等同于禁止指定成员发言;服务端缺少群禁言策略。 +5. 文件下载只校验 API Key 和登录用户,没有根据文件关联消息、Topic ACL、发送者或接收者判断访问权限。 +6. WebRTC 只维护 P2P Topic 的一个当前呼叫,缺少稳定的业务 `call_id`、跨设备抢答、通话详单、失败原因规范和群通话能力。 +7. 没有企业、组织、部门、会议、日报、月报、信箱等领域模型。 +8. 没有实名认证审批、反诈策略、举报工单、反馈工单、青少年模式的服务端强制规则。 +9. 没有租户字段;共享数据库的企业 SaaS 部署会有数据越界风险。 + +## 4. 总体改造原则 + +### 4.1 保留通信内核,新增产品业务层 + +不建议将会议、日报、实名认证等业务硬塞进 Topic 的 Public/Aux JSON。Aux 适合兼容性元数据,不适合作为需要索引、唯一约束、状态机、审批记录和审计日志的主数据。 + +推荐分为四层: + +1. **Tinode 实时内核**:Session、Hub、Topic、ACL、Message、Push、WebRTC 信令; +2. **IM 产品策略层**:结构化消息解析、发消息前鉴权、好友/黑名单/群禁言/青少年模式校验; +3. **业务服务层**:好友申请、群审批、组织、会议、报告、实名认证、举报等 HTTP API; +4. **业务存储与事件层**:业务表、事务、Outbox、审计日志、搜索索引。 + +### 4.2 目标架构 + +```mermaid +flowchart TB + APP["iOS / Android / Web"] + + subgraph Gateway["同一 Go 服务进程或同域网关"] + WS["现有实时协议入口"] + API["新增 /v1/im/* 业务 API"] + FILE["文件上传/下载"] + end + + subgraph Core["通信与产品策略"] + SESSION["Session / Hub / Topic"] + POLICY["IM Policy Engine"] + CALL["Call Signaling"] + NOTIFY["Notification Bridge"] + end + + subgraph Business["业务模块"] + REL["好友与黑名单"] + GROUP["群治理"] + ORG["组织与工作台"] + SAFETY["实名 / 青少年 / 举报 / 风控"] + SEARCH["消息与文件索引"] + end + + subgraph Infra["存储与外部系统"] + DB["核心表 + im_* 业务表"] + OUTBOX["Outbox / 异步任务"] + MOD["外部审核与反诈服务"] + PUSH["Push / SMS / 邮件"] + MEDIA["对象存储 / 转码 / 病毒扫描"] + end + + APP --> WS + APP --> API + APP --> FILE + WS --> SESSION + SESSION --> POLICY + POLICY --> DB + API --> Business + Business --> DB + Business --> OUTBOX + OUTBOX --> NOTIFY + NOTIFY --> SESSION + SESSION --> CALL + POLICY --> MOD + FILE --> MEDIA + SESSION --> PUSH +``` + +### 4.3 WebSocket 与 HTTP 的职责边界 + +| 场景 | 推荐通道 | 原因 | +| --- | --- | --- | +| 发消息、回执、输入中、在线事件、通话信令 | 现有 WebSocket | 低延迟、已有 Topic 路由和广播 | +| 好友申请/审批、群申请/审批 | HTTP 写操作 + WS 通知 | 需要幂等、状态机、审计和列表查询 | +| 组织架构、日报/月报、会议管理 | HTTP API | 强查询和事务型业务,不应阻塞 Topic | +| 消息关键词/类型搜索 | HTTP 或扩展后的 `get` | 需要独立索引、分页游标和查询权限 | +| 实名认证、举报、反馈、版本配置 | HTTP API | 涉及附件、敏感字段、工单和后台管理 | +| 文件上传/下载 | HTTP | 沿用当前链路,但补资源级授权 | +| 业务状态变化提醒 | 结构化系统消息/系统 Topic | 复用实时和推送能力 | + +## 5. 11 类原型需求的服务端适配方案 + +### 5.1 账号注册、登录与身份安全 + +| 原型能力 | 现状 | 改造方案 | 优先级 | +| --- | --- | --- | --- | +| 企业码登录 | 无企业模型 | 新增企业码解析接口;企业码映射到企业、部署地址和登录策略 | P0 | +| 手机号/密码登录 | 认证框架已有 | 固化账号标识规范、失败次数、锁定时长、设备记录和安全审计 | P0 | +| 注册和验证码倒计时 | 电话验证器已有 | 新增注册编排接口;倒计时由客户端显示,服务端返回 `retry_after`、过期时间和重试上限 | P0 | +| 忘记密码 | 有认证与验证器,无完整流程 | 增加发送验证码、校验票据、重置密码三个阶段;票据一次性、短时有效 | P0 | +| 设置独立密码 | 可更新账号,但无产品流程 | 增加二次验证和密码策略;写审计日志并撤销旧 Token | P1 | +| 实名认证 | 无 | 新建实名申请、状态查询、审核回调;敏感字段加密,客户端仅返回脱敏结果 | P1 | + +企业码有两种实现方式: + +- **推荐第一阶段:一企一实例/一企一库。** 企业码只负责发现该企业的服务地址和认证方式。现有核心表无需立即加入 `tenant_id`,隔离边界清晰。 +- **共享 SaaS:多企业共用服务和数据库。** 必须先完成第 6 节的全链路租户隔离,再开放企业码登录。 + +建议新增接口: + +```text +POST /v1/im/auth/enterprise/resolve +POST /v1/im/auth/sms/send +POST /v1/im/auth/password/reset-ticket +POST /v1/im/auth/password/reset +POST /v1/im/identity/verifications +GET /v1/im/identity/verifications/current +``` + +不要把身份证号、证件照片地址写入 User.Public、User.Trusted 或消息内容。实名数据应单独加密存储,并限制后台角色、访问理由和留痕。 + +### 5.2 消息首页、全局导航与系统通知 + +| 原型能力 | 现状 | 改造方案 | 优先级 | +| --- | --- | --- | --- | +| 会话列表 | Subscription 已有未读、时间等信息 | 扩展每用户会话设置:置顶、免打扰、草稿、隐藏;草稿可优先本地保存 | P1 | +| 离线/重连 | Session 支持连接和队列 | 客户端指数退避;服务端增加连接状态指标、消息同步游标和限流 | P0 | +| 长按置顶/删除/免打扰 | 部分可由 Private/订阅状态承载 | 明确 `im_conversation_settings`,避免 Private JSON 无法查询和约束 | P1 | +| 系统消息 | 可创建系统 Topic/系统账号 | 建立系统消息类型字典、模板版本、跳转参数和去重键 | P1 | + +系统消息应使用正常的 Message 存储和 Push 链路,而不是只发临时 `info` 包。这样用户离线后仍可拉取、已读和跨设备同步。 + +### 5.3 单聊会话、会话建立与消息状态 + +| 原型能力 | 现状 | 改造方案 | 优先级 | +| --- | --- | --- | --- | +| 单聊建立 | P2P Topic 已支持 | 在创建/订阅前检查好友、黑名单和隐私策略 | P0 | +| 在线、输入中 | Presence、`kp` 已支持 | 统一客户端节流和过期时间;按隐私设置决定是否透出 | P1 | +| 已发送、已送达、已读 | Topic 序号和 `recv/read` 已支持 | 定义产品状态映射;群聊展示规则单独定义 | P0 | +| 拉黑后限制沟通 | 无完整关系表 | 关系表作为真源;发布、建会话、呼叫、文件访问均执行同一策略 | P0 | +| 删除消息/撤回 | 有消息删除能力 | 区分“仅自己删除”和“全员撤回”;增加撤回时限、操作者和审计事件 | P1 | +| 名片消息 | 通用 JSON 可承载 | 定义 `contact_card` 类型,只保存稳定用户 ID 和展示快照,打开时重新鉴权 | P1 | + +“拉黑”不能只修改客户端按钮或 Topic 私有字段。策略层至少要拦截:新建单聊、发送消息、发送好友请求、音视频呼叫、读取对方敏感资料。 + +### 5.4 消息输入、媒体内容与消息操作 + +当前 `head`、`content` 接受通用 JSON,技术上可以传文本、图片、语音、视频、文件、名片、合并转发等内容,但服务端没有类型白名单、字段校验、幂等、审核和索引。建议增加明确的消息信封: + +```json +{ + "pub": { + "id": "client-request-id", + "topic": "grp...", + "head": { + "x-im-schema": 1, + "x-im-type": "image", + "x-im-client-mid": "01J...", + "x-im-reply-to": 128 + }, + "content": { + "file_id": "f...", + "width": 1080, + "height": 1440, + "thumbnail_file_id": "f..." + } + } +} +``` + +服务端改造要求: + +1. 在 `server/datamodel.go` 定义扩展字段常量和允许类型,不再由各客户端自由命名。 +2. 在 `server/session.go` 发布入口解析 `x-im-client-mid`,按“租户 + 发送者 + client_mid”去重;重复请求返回第一次成功的 Topic/SeqId。 +3. 在 `server/topic.go` 持久化前执行类型、大小、引用消息、附件所有权、好友/黑名单、禁言、青少年和风控策略。 +4. 文本继续使用 Drafty;图片、视频、语音、文件只在消息里保存 `file_id` 和必要元数据,不信任客户端提交的任意下载 URL。 +5. `@成员` 保存稳定用户 ID 列表;服务端校验被提醒者确实是当前群成员,并生成定向推送。 +6. 合并转发生成不可变快照,保留原作者展示名、时间和内容类型,但不得泄露原会话 ID 或无权访问的附件。 +7. 多选、键盘、表情面板、录音进度、上传进度属于客户端交互;服务端只负责资源、消息和失败状态。 + +推荐消息类型首批固定为: + +```text +text, image, voice, video, file, contact_card, +location, merged_forward, system_notice, call_record +``` + +转发应区分两种语义: + +- **逐条转发**:为每条内容创建新消息,原附件通过授权后重新建立引用; +- **合并转发**:创建一个 `merged_forward` 快照,子项限制数量和总大小,服务端清理敏感字段。 + +### 5.5 通讯录、好友关系与黑名单 + +当前 Subscription 表示“用户订阅了哪个 Topic”,不能替代双边好友关系和申请状态机。建议新增: + +- `im_user_relations`:双方关系、备注、黑名单、免打扰等当前状态; +- `im_friend_requests`:申请、处理人、验证信息、状态、过期时间和幂等键; +- `im_privacy_settings`:允许通过手机号/ID/二维码查找、加好友验证方式等。 + +好友流程: + +```mermaid +stateDiagram-v2 + [*] --> Pending: 发起申请 + Pending --> Accepted: 接受 + Pending --> Rejected: 拒绝 + Pending --> Cancelled: 发起人撤回 + Pending --> Expired: 超时 + Accepted --> Deleted: 任一方删除 + Accepted --> Blocked: 任一方拉黑 + Blocked --> Accepted: 取消拉黑且关系仍保留 +``` + +实现要点: + +1. 精准用户 ID 搜索必须受隐私设置、租户和账号状态限制;手机号搜索应使用规范化哈希进行匹配,禁止模糊枚举。 +2. 接受好友申请和建立双方关系必须在同一数据库事务内完成,并通过 Outbox 异步创建/激活 P2P Topic、发送系统通知。 +3. 删除好友是否删除 P2P 历史需产品确认。建议只解除关系,不物理删除历史;双方分别控制会话是否可见。 +4. 拉黑属于单方策略,服务端立即生效。是否同时解除好友关系应作为明确产品规则,不由客户端猜测。 +5. 关系变化必须使 ACL/策略缓存失效,避免短时间内继续发消息。 + +建议接口: + +```text +GET /v1/im/contacts +GET /v1/im/users/exact-search?id=... +POST /v1/im/friend-requests +GET /v1/im/friend-requests +POST /v1/im/friend-requests/{id}/accept +POST /v1/im/friend-requests/{id}/reject +DELETE /v1/im/contacts/{user_id} +PUT /v1/im/contacts/{user_id}/block +DELETE /v1/im/contacts/{user_id}/block +GET /v1/im/blocks +``` + +### 5.6 群聊创建、资料维护与成员治理 + +现有群 Topic、Owner/Admin ACL 和所有者转移可以复用。需要新增群业务规则和审批数据。 + +| 原型能力 | 可复用基础 | 新增服务端能力 | +| --- | --- | --- | +| 创建群、群资料 | Group Topic、Public/Trusted/Aux | 资料字段规范、头像资源校验、敏感词审核 | +| 加入群聊 | Subscription/Join ACL | 入群方式、申请表、审批状态机、人数和频率限制 | +| 邀请进群 | Admin/Share ACL | 邀请记录、邀请权限、被邀请人确认、批量幂等 | +| 群公告 | 消息可承载 | 公告主表、版本、置顶、已读回执、发布权限 | +| 管理员 | Admin ACL | 管理员人数上限、操作审计、角色显示 | +| 禁言成员 | 无对应强制策略 | 单人/全员禁言表和发布前校验,管理员豁免规则 | +| 转让群主 | 已有 Owner 转移逻辑 | 二次确认、风险校验、审计和通知 | +| 群二维码 | 无 | 签名短 Token、有效期、次数限制、撤销和入群策略 | +| 群文件 | 文件与消息已有关联 | 群文件索引、上传者/类型/时间筛选、删除权限 | + +当前订阅代码在新订阅者没有 Join 权限时会拒绝加入,因此不能仅用“`ModeGiven` 不含 Join”来保存待审批申请。正确做法是先写 `im_group_join_requests`,审批通过后再创建或更新 Subscription。 + +群禁言必须在消息持久化前检查,建议规则优先级为: + +```text +账号停用 > 黑名单/关系限制 > 全员禁言 > 单人禁言 > Topic Write ACL > 允许发送 +``` + +群二维码只应包含服务端生成的短 Token,不应直接暴露可永久加入的 Topic ID。Token 至少绑定群、创建人、过期时间、最大使用次数和当前入群策略,并使用服务端密钥签名或只保存其哈希。 + +### 5.7 文件下载、收藏管理与聊天记录检索 + +#### 文件访问安全 + +这是当前代码中最明确的安全缺口。`server/hdl_files.go` 的下载流程验证 API Key 和已登录用户后即可读取 URL 对应文件,没有验证该用户是否是上传者、是否属于关联消息的 Topic、该消息是否已撤回,或文件是否为公开资源。 + +建议新增统一的 `FileCanAccess(uid, fileID, action)`: + +1. 查询 FileDef 和 file-message links; +2. 上传未完成的文件只允许上传者访问; +3. 已关联消息的文件要求用户对至少一个关联 Topic 具有 Read 权限; +4. 群文件删除要求上传者、群管理员或群主权限; +5. 转发附件时重新建立授权关联,不暴露底层存储永久地址; +6. 使用短时签名下载 URL,记录下载审计; +7. 对上传文件执行 MIME 嗅探、扩展名一致性、病毒扫描、图片/视频解码安全检查。 + +#### 收藏 + +`slf` Topic 可以继续承担“收藏内容跨设备同步”的消息容器,但建议增加 `im_favorites` 索引表,保存源消息、收藏消息、类型、创建时间和已清理的展示摘要。源消息删除后,收藏快照是否保留需按合规策略处理。 + +#### 聊天记录检索 + +当前 `MessageGetAll` 仅支持 Topic、序号范围和数量,不支持关键词或类型。建议新增 `im_message_index`: + +| 字段 | 用途 | +| --- | --- | +| tenant_id / topic / seq_id | 权限过滤和定位原消息 | +| sender_id / message_type | 发送人和类型筛选 | +| sent_at | 时间范围和排序 | +| searchable_text | 文本、文件名、链接标题等可搜索文本 | +| file_id / mime_group | 文件、图片、视频分类 | +| deleted / moderation_state | 排除已删除或不可见内容 | + +若仅支持 MySQL,可使用 InnoDB FULLTEXT 配合 `ngram` 分词;若需要更强中文检索、跨话题检索和高数据量,建议使用 OpenSearch/Elasticsearch。无论使用哪种索引,查询结果都必须再次以当前 Topic Read ACL、消息删除范围和租户进行过滤,不能把搜索索引当作授权来源。 + +需要提供全量回填任务和增量 Outbox 消费者,避免上线后只能搜索新消息。 + +### 5.8 实时语音与视频通话 + +现有 `server/calls.go` 已支持 P2P 呼叫的邀请、接听、Offer、Answer、ICE Candidate 和挂断,可作为首期基础。改造建议: + +1. 为每次呼叫生成不可复用的 `call_id`,不要只用 Topic 和消息 SeqId 表示一次通话; +2. 增加 `voice/video` 类型、主叫/被叫设备、创建/响铃/接听/结束时间、结束方、标准结束原因; +3. 增加跨设备抢答:一台设备接听后,其他设备收到 `answered_elsewhere`; +4. 呼叫前执行好友、黑名单、隐私、账号状态和青少年策略; +5. 呼叫超时、拒接、忙线、取消分别生成一致的通话记录消息和推送; +6. 配置可用的 STUN/TURN,监控 ICE 成功率和呼叫建立耗时; +7. 麦克风、扬声器、摄像头开关和悬浮窗主要由客户端管理,服务端只同步必要的媒体状态事件; +8. 群音视频不应扩展当前单个 `videoCall` 结构硬做,建议另建会议房间并接入 SFU。 + +### 5.9 企业工作台与办公协同 + +该部分属于全新业务域,当前服务端没有组织、部门、会议、日报、月报或信箱代码。建议它们作为独立业务模块,通过 Tinode 系统消息发送提醒,而不是修改聊天核心协议承载所有 CRUD。 + +#### 组织架构 + +- `im_org_units`:企业、部门、层级、排序、负责人、状态; +- `im_org_members`:用户、部门、职位、主部门、在职状态和可见范围; +- 支持树形查询、按姓名/部门搜索、部门成员分页; +- 组织同步应有版本号,客户端可增量刷新; +- 离职用户需在一个事务编排中禁用账号、退出企业群、撤销 Token 和处理数据归属。 + +#### 会议通知 + +- `im_meetings`:主题、时间、地点/会议链接、发起人、提醒策略、状态; +- `im_meeting_participants`:参与人、回复状态、回复时间; +- 创建/变更/取消写 Outbox,由通知桥接器向参与者系统 Topic 发结构化消息; +- 定时提醒由任务调度器执行,任务必须使用幂等键避免重复推送; +- 若未来增加在线视频会议,会议业务 ID 与通话房间 ID 分离。 + +#### 日报与月报 + +- 统一使用 `im_work_reports`,字段包含类型、周期、作者、部门、正文、附件、状态、提交时间; +- 管理员列表以权限范围过滤,不以客户端传入部门为准; +- 提交后是否可编辑、补交和撤回需形成明确状态机; +- 汇总统计异步生成,不在请求中扫描所有报告。 + +#### 总经理信箱 + +- 使用 `im_mailbox_messages`,支持实名/匿名展示策略、正文、附件、处理状态和回复; +- “匿名”只能对业务查看者隐藏,安全审计角色仍可在合法授权下追溯; +- 附件走统一私有文件授权; +- 每次查看和导出敏感信件都写审计日志。 + +### 5.10 个人资料、通用设置、隐私与青少年模式 + +| 能力 | 服务端责任 | 客户端责任 | +| --- | --- | --- | +| 昵称、生日、签名、头像 | 校验、敏感词、可见范围、版本和审计 | 编辑和展示 | +| 个人二维码 | 生成短时签名 Token、隐私校验 | 展示、扫码 | +| 清空缓存 | 无需删除服务端消息 | 清理本地缓存和下载文件 | +| 版本更新 | 返回平台、渠道、最低版本、推荐版本、下载地址和更新文案 | 下载、安装、商店跳转 | +| 隐私设置 | 作为服务端授权条件强制执行 | 提供开关界面 | +| 青少年模式 | 服务端保存状态、PIN 哈希、策略版本并强制限制 | UI 切换和本地内容隐藏 | +| 推送/相机/麦克风权限 | 保存推送 Token 和提醒偏好 | 调用系统权限 API | + +青少年模式不能只是客户端开关,否则卸载重装或换设备即可绕过。建议 `im_teen_mode` 保存启用状态、监护 PIN 的强哈希、失败锁定、允许时段、功能策略版本和更新时间。服务端在登录、搜索、加好友、发消息、通话和工作台入口统一检查策略。 + +版本接口示例: + +```text +GET /v1/im/config/app-version?platform=android&channel=official&version=1.4.0 +``` + +响应需区分 `latest`、`recommended`、`minimum_supported` 和 `force_update`。客户端系统权限文案和弹窗不需要服务端逐页参与,但可以通过配置中心提供版本化文案。 + +### 5.11 反诈安全、举报与意见反馈 + +建议形成三层控制: + +1. **同步硬规则**:账号状态、黑名单、限频、群禁言、文件大小/类型等,必须在服务端本地快速判断; +2. **内容与风险审核**:通过现有 gRPC Plugin Firehose 或独立审核服务检查文本、图片和链接; +3. **事后处置**:举报工单、证据固化、审核、处罚、申诉和审计。 + +现有插件在协议分发之前同步执行,严格审核会直接增加消息延迟。外部审核调用必须设置较短超时、熔断、指标和明确的 fail-open/fail-closed 策略。高风险场景可以先将消息标为 `pending_review`,审核通过后再广播;低风险场景可先发后审并支持撤回。 + +新增数据模型: + +- `im_reports`:举报对象、原因、描述、提交人、状态、处理人、结论; +- `im_report_evidence`:消息快照、文件引用、校验哈希; +- `im_feedback`:意见类型、正文、联系方式、附件、处理状态; +- `im_risk_events`:命中规则、风险等级、处置、模型/规则版本; +- `im_audit_logs`:操作者、动作、对象、结果、IP、设备和关联请求 ID。 + +举报消息时不要只保存可变的 Topic/SeqId,应在用户仍有读取权限时由服务端固化必要证据快照和内容哈希。后台读取证据需要单独权限和完整审计。 + +## 6. 企业租户隔离决策 + +### 6.1 当前事实 + +当前 User、Topic、Subscription、Message 和 FileDef 没有 `tenant_id`。用户标签和 Topic 标签也没有企业隔离维度。仅在登录入口识别企业码,不能保证后续搜索、消息、文件和后台查询不会跨企业。 + +### 6.2 推荐方案:第一阶段一企一实例/一企一库 + +企业码网关返回企业专属服务地址。每个实例使用独立数据库、对象存储前缀、推送配置和审核配置。这种方案最贴合当前架构,改造量和误配风险最低,也便于企业级数据迁移与删除。 + +需要新增: + +- 企业码目录服务; +- 企业到服务地址/认证策略的映射; +- 配置和密钥隔离; +- 统一运维、监控和版本发布能力。 + +### 6.3 共享 SaaS 的必要改造 + +如果明确要求多个企业共用一套服务和数据库,则以下工作必须先于产品功能: + +1. 为核心表和所有业务表增加 `tenant_id`; +2. 所有唯一索引包含租户维度,例如用户登录标识、Topic、客户端消息 ID; +3. Session 完成认证后固定 tenant,禁止客户端包覆盖; +4. Topic 查找、用户查找、订阅、消息读写、文件访问和搜索全部强制带 tenant; +5. 内存缓存、Hub 路由键、集群路由和 Push 任务均包含 tenant; +6. 系统账号和系统 Topic 按企业创建; +7. 后台管理账号采用企业范围和数据范围授权; +8. 增加跨租户攻击自动化测试,覆盖枚举 ID、文件 URL、搜索和转发。 + +这不是加一个字段的局部修改,而是横跨认证、存储接口、全部数据库适配器、缓存、集群路由和测试的基础工程。 + +## 7. 协议与 API 改造 + +### 7.1 保持现有协议兼容 + +继续支持现有 `hi`、`acc`、`login`、`sub`、`leave`、`pub`、`get`、`set`、`del`、`note`。新客户端通过 `x-im-schema` 声明产品扩展版本;旧客户端没有扩展字段时仍按现有路径工作。 + +推荐新增固定消息头: + +| 字段 | 必填条件 | 说明 | +| --- | --- | --- | +| `x-im-schema` | 产品消息必填 | 扩展协议版本 | +| `x-im-type` | 产品消息必填 | 消息类型枚举 | +| `x-im-client-mid` | 普通消息必填 | 客户端生成的幂等 ID | +| `x-im-reply-to` | 回复消息时 | 被回复消息 SeqId | +| `x-im-forward-mode` | 转发时 | `single` 或 `merged` | +| `x-im-risk-state` | 仅服务端写 | 审核状态,客户端提交值必须忽略 | + +### 7.2 消息幂等 + +新增唯一约束: + +```text +(tenant_id, sender_id, client_mid) UNIQUE +``` + +一企一库时可省略物理 `tenant_id`,但代码接口仍建议预留租户上下文。幂等记录需要保存最终 Topic、SeqId 和响应摘要。消息保存、Topic 最新序号、订阅更新目前通过多次 Store 调用完成;新增幂等时应明确事务边界,避免数据库写成功但回复丢失后重试产生两条消息。 + +### 7.3 查询扩展 + +不建议继续把搜索条件塞进未定义的任意 JSON。可在 `MsgGetQuery` 中增加明确字段: + +```go +type MsgSearchQuery struct { + Query string `json:"query,omitempty"` + Types []string `json:"types,omitempty"` + From string `json:"from,omitempty"` + SinceTime string `json:"since_time,omitempty"` + BeforeTime string `json:"before_time,omitempty"` + Cursor string `json:"cursor,omitempty"` + Limit int `json:"limit,omitempty"` +} +``` + +如果搜索由独立服务承担,则提供 `/v1/im/search/messages`,返回 Topic、SeqId 和安全摘要,客户端再通过原生 `get data` 拉取上下文。任何方案都必须在服务端重新做 Topic ACL 检查。 + +### 7.4 业务 API 约定 + +新增 `/v1/im/*` 路由,复用 Tinode Token 的认证结果。应把 `hdl_files.go` 中现有的请求认证逻辑抽取成通用 HTTP 中间件,而不是让每个 Handler 自行解析 Token。 + +所有写接口统一支持: + +- `X-Request-ID`:链路追踪; +- `Idempotency-Key`:创建和审批的幂等控制; +- 统一错误结构:`code`、`message`、`details`、`request_id`; +- 游标分页,不使用数据增长时不稳定的大 Offset; +- 服务端从认证上下文取用户和租户,不接受正文伪造; +- 状态变更写审计日志和 Outbox。 + +## 8. 建议新增的数据模型 + +以下是逻辑模型,正式建表前需补充字段长度、外键策略、冷热分层和数据保留周期。 + +| 表 | 核心字段 | 关键约束/索引 | 作用 | +| --- | --- | --- | --- | +| `im_user_relations` | user_id、peer_id、state、remark、blocked、muted | 双向记录唯一;peer/state 索引 | 好友、备注、拉黑和通知关系 | +| `im_friend_requests` | id、from、to、message、state、expires_at | 待处理申请去重;to/state/time | 好友申请状态机 | +| `im_conversation_settings` | user_id、topic、pinned、muted、hidden | user/topic 唯一 | 会话个性化设置 | +| `im_privacy_settings` | user_id、search flags、friend policy | user 唯一 | 精准搜索和加好友授权 | +| `im_group_settings` | topic、join_policy、invite_policy、mute_all | topic 唯一 | 群业务规则 | +| `im_group_join_requests` | id、topic、applicant、inviter、state | topic/applicant/pending 去重 | 入群申请与审批 | +| `im_group_mutes` | topic、user、expires_at、operator | topic/user 唯一;expires 索引 | 单人禁言 | +| `im_group_announcements` | id、topic、version、content、publisher | topic/status/time | 群公告版本 | +| `im_group_announcement_reads` | announcement_id、user、read_at | announcement/user 唯一 | 公告已读 | +| `im_group_invite_tokens` | token_hash、topic、expires、max_uses | token_hash 唯一;expires | 群二维码/邀请链接 | +| `im_message_idempotency` | sender、client_mid、topic、seq_id | sender/client_mid 唯一 | 消息去重 | +| `im_message_index` | topic、seq_id、type、text、file_id、sent_at | topic/seq 唯一;搜索索引 | 消息、文件和媒体检索 | +| `im_favorites` | user、favorite_seq、source topic/seq、type | user/time;源消息索引 | 收藏筛选与分享 | +| `im_identity_verifications` | user、encrypted PII、state、review | user/current-state;request id | 实名认证和审计 | +| `im_org_units` | id、parent_id、name、path、state | parent/sort;path | 企业组织树 | +| `im_org_members` | user、org_unit、title、primary | unit/state;user | 部门成员关系 | +| `im_meetings` | id、organizer、title、start/end、state | organizer/time;state/time | 会议通知 | +| `im_meeting_participants` | meeting、user、response | meeting/user 唯一 | 参会状态 | +| `im_work_reports` | type、period、author、department、content、state | author/type/period;dept/time | 日报/月报 | +| `im_mailbox_messages` | id、sender、content、anonymous、state | state/time;sender/time | 总经理信箱 | +| `im_user_settings` | user、setting key/value、version | user/key 唯一 | 跨设备设置 | +| `im_teen_mode` | user、enabled、pin_hash、policy_version | user 唯一 | 青少年策略 | +| `im_reports` | reporter、target_type/id、reason、state | state/time;target | 举报工单 | +| `im_report_evidence` | report、snapshot、file、hash | report | 证据固化 | +| `im_feedback` | user、category、content、state | state/time;user/time | 意见反馈 | +| `im_risk_events` | actor、object、rule、level、action | actor/time;object | 风控记录 | +| `im_audit_logs` | actor、action、object、result、request_id | actor/time;object/time | 管理和敏感操作审计 | +| `im_outbox` | aggregate、event_type、payload、state | state/next_retry;dedupe key | 事务后可靠通知 | + +所有表在共享 SaaS 模式下都必须包含 `tenant_id`,并将它放入唯一约束和查询前缀。软删除字段不能代替状态机和审计记录。 + +## 9. 代码级改造清单 + +### 9.1 现有文件修改 + +| 文件 | 建议修改 | +| --- | --- | +| `server/datamodel.go` | 定义产品消息头、消息类型、查询过滤和错误码;保持旧协议兼容 | +| `server/session.go` | 发布前幂等校验;调用产品策略层;统一映射业务错误;认证后绑定租户上下文 | +| `server/topic.go` | 发布前关系/禁言/青少年策略;结构化系统消息;群管理状态变化后的缓存失效 | +| `server/calls.go` | 引入 call_id、设备维度、结束原因、抢答与通话详单;群通话走独立模块 | +| `server/push.go` | 按消息类型生成 Push;支持 @提醒、审批、会议和审核状态;避免敏感内容出现在锁屏 | +| `server/hdl_files.go` | 抽取通用 HTTP 认证;下载增加 FileCanAccess;签名 URL;扫描状态检查 | +| `server/plugins.go` | 为外部审核增加超时、指标、熔断和场景化失败策略 | +| `server/main.go` | 注册 `/v1/im/*` 路由、业务模块生命周期、健康检查和后台任务 | +| `server/store/store.go` | 增加幂等、文件授权和搜索所需的核心接口,明确事务边界 | +| `server/store/types/types.go` | 增加明确的扩展类型;若共享 SaaS,核心实体加入 TenantId | +| `server/db/mysql/adapter.go` | schema 升级、索引、幂等和核心查询实现 | +| `server/db/mysql/schema.sql` | 与 adapter 中建表 SQL 同步,禁止只改其中一份 | +| `tinode.conf` | 产品模块、租户、搜索、审核、TURN、文件扫描和限流配置 | + +### 9.2 建议新增包 + +```text +server/imapi/ HTTP 路由、请求校验、响应和认证中间件 +server/impolicy/ 好友、黑名单、群禁言、隐私、青少年等同步策略 +server/immessage/ 消息类型注册、结构校验、摘要与转发净化 +server/imbiz/ 好友、群治理、组织、会议、报告、实名、举报服务 +server/imstore/ 产品业务存储接口和 MySQL 实现 +server/imnotify/ Outbox 消费、系统消息和 Push 桥接 +server/imsearch/ 索引写入、回填、检索和 ACL 二次过滤 +server/imjobs/ 过期申请、会议提醒、清理、索引回填等后台任务 +``` + +### 9.3 数据库适配策略 + +当前项目同时包含 MySQL、PostgreSQL、MongoDB 和 RethinkDB 适配器。新增所有产品能力到公共 Store 接口会要求四套实现同步完成,改造面很大。 + +建议先明确产品正式支持的数据库: + +- 如果生产只使用 MySQL,则产品业务 Store 首期实现 MySQL,并在启用 `im_product` 配置且底层不支持时拒绝启动,不能静默降级;

WebSocket 第一条消息必须是 `{hi}`,其中 `tenant` 为企业码。服务端解析后把租户固定到 Session。 +3. Token 内部绑定租户。Token 租户与当前 Session 租户不一致时返回 `TENANT_MISMATCH`,不得自动切换。 +4. 切换企业必须退出登录、关闭 WebSocket、清除该租户的 Token/缓存,再重新解析企业码和握手。 +5. 已登录 HTTP 请求的租户和用户只从 Token Principal 获取。请求体中的 `tenant_id`、`user_id` 不能覆盖身份。 +6. 跨租户对象统一返回 `RESOURCE_NOT_FOUND` 或 `FORBIDDEN`,不得暴露对象是否存在。 + +### 0.4 HTTP 请求与响应 + +成功响应统一为: + +```json +{ + "code": 0, + "data": {}, + "request_id": "01K...", + "server_time":

"2026-08-11T08:30:15.123Z" +} +``` + +客户端只使用稳定的 `reason` 分支和本地化文案,不解析 `message`。ID、Topic、Seq 游标在客户端均按字符串处理;时间统一为 UTC RFC3339 毫秒。分页统一使用 `limit` 与不透明 `cursor`,返回 `items`、`next_cursor`、`has_more`。 + +### 0.5 WebSocket 建连、登录和恢复顺序 + +#### 0.5.1 现有服务端可直接执行的冷启动流程 + +```text +读取客户端预置的 host 和普通 API Key +-> 用户输入/客户端读取 tenant_code +-> 带 API Key 完成 WebSocket Upgrade +-> hi(tenant_code) +-> 收到 hi 的 201 ctrl,确认 tenant 与服务端限制 +-> 有历史 Token 时 token login,否则 basic login/acc +-> 收到 login 的 200 ctrl,保存 user/token/expires +-> sub(me) 拉取本人资料和会话订阅 +-> sub(fnd) 建立搜索 Topic +-> 订阅需要在线的会话并按 seq 增量拉取 +-> 进入可发送状态 +``` + +当前服务端没有 `/v1/im/tenants/resolve`,因此现阶段企业码是否有效是在第一帧 `{hi}` 中校验的。只有 WebSocket Upgrade 返回 `101 Switching Protocols` 后才能发送下面的 JSON 文本帧。 + +`hi` 请求: + +```json +{"hi":{"id":"hi-1","ver":"0.25","ua":"android/1.0.0","dev":"device-id","lang":"zh-CN","tenant":"acme"}} +``` + +`login` 请求使用 `basic` 或 `token`: + +```json +{"login":{"id":"login-1","scheme":"basic","secret":"base64(username:password)"}} +``` + +```json +{"login":{"id":"login-2","scheme":"token","secret":"<上次登录响应原样返回的 token 字符串>"}} +``` + +`basic.secret` 是 `base64(username + ":" + password)`。Token 登录必须把上次 `params.token` 的 JSON 字符串原样填入 `secret`,不能再次 Base64 编码。登录成功 `{ctrl}` 的 `params` 至少包含 `user`、`authlvl`、`token`、`expires`。Token 对客户端是不可解析的 opaque 字符串,只能存入系统安全存储。`id` 只用于匹配本次 Session 的命令响应,不是业务幂等键。 + +`hi` 成功示例: + +```json +{ + "ctrl": { + "id": "hi-1", + "code": 201, + "text": "created", + "params": { + "ver": "0.25", + "tenant": {"code": "acme", "name": "示例企业"}, + "maxFileUploadSize": 104857600, + "callTimeout": 30, + "iceServers": [] + } + } +} +``` + +客户端只使用实际响应中存在的限制字段;未知字段忽略。`hi` 返回非 2xx 时必须关闭连接,不得继续发送 `login`。 + +登录成功后发送: + +```json +{"sub":{"id":"sub-me-1","topic":"me","get":{"what":"desc sub tags cred"}}} +``` + +客户端按相同 `id` 接收 `{ctrl}` 和一个或多个 `{meta}`,从 `meta.desc` 取得本人资料和读写游标,从 `meta.sub` 取得会话 Topic、访问权限、`seq/read/recv` 与会话摘要。不要依赖 `{ctrl}`、`{meta}` 的固定先后顺序。 + +随后建立查找 Topic: + +```json +{"sub":{"id":"sub-fnd-1","topic":"fnd"}} +``` + +进入具体会话时订阅并增量拉取,`since` 使用客户端已完整持久化的最后 `seq + 1`: + +```json +{"sub":{"id":"sub-topic-1","topic":"grp...","get":{"what":"desc sub data del","data":{"since":125,"limit":50},"del":{"since":1,"limit":50}}}} +``` + +订阅成功后才允许 `{pub}`、`note read/recv` 等会话操作。断线恢复必须重新执行 `WebSocket Upgrade -> hi -> token login -> sub me -> 恢复 Topic`,同一连接内不得跳过 `hi` 或切换企业码。 + +#### 0.5.2 Long Polling 兼容流程:先取得的是 sid + +如果客户端无法使用 WebSocket,可以使用现有 `/v0/channels/lp`。该模式确实需要“先请求取得一个值”,但取得的是短期 Session ID `sid`,API Key 仍然必须由客户端预先持有。 + +第一步,创建 Long Polling Session: + +```http +POST /v0/channels/lp HTTP/1.1 +Host: im.example.com +X-Tinode-APIKey: <预置的普通 API Key> +Content-Length: 0 +``` + +服务端返回 HTTP 201: + +```json +{"ctrl":{"code":201,"text":"created","params":{"sid":"session-id"},"ts":"2026-08-11T08:30:15.123Z"}} +``` + +第二步开始,所有 Long Polling 请求都同时携带 API Key 和 `sid`。发送 `hi`: + +```http +POST /v0/channels/lp?sid=session-id HTTP/1.1 +X-Tinode-APIKey: <预置的普通 API Key> +Content-Type: application/json + +{"hi":{"id":"hi-1","ver":"0.25","ua":"android/1.0.0","platf":"android","lang":"zh-CN","tenant":"acme"}} +``` + +POST 只负责把命令送入 Session。客户端再保持一个不带 Body 的 GET 来接收下一条 `{ctrl}`、`{meta}`、`{data}`、`{pres}` 或 `{info}`: + +```http +GET /v0/channels/lp?sid=session-id HTTP/1.1 +X-Tinode-APIKey: <预置的普通 API Key> +``` + +收到 `hi` 成功后,以相同方式 POST `{login}`,再 GET 登录结果;登录成功后依次 POST `{sub me}`、`{sub fnd}` 和会话订阅,并持续发起下一次 GET 等待下行消息。 + +`sid` 无效或过期时服务端返回 HTTP 403 `invalid or expired session`,客户端必须重新创建 Long Polling Session 并从 `hi` 开始,不能只重发 `login`。Long Polling 是兼容方案,移动端和 Web 端正常网络条件下优先使用 WebSocket。 + +#### 0.5.3 目标产品流程 + +第 1.1 节规划的 `POST /v1/im/tenants/resolve` 属于新增接口。实现后目标流程调整为: + +```text +读取预置 API Key +-> POST /v1/im/tenants/resolve 校验企业码并取得服务地址/品牌配置 +-> 带同一 API Key 建立返回地址的 WebSocket +-> hi 再次绑定并校验 tenant_code +-> login -> sub me -> 恢复会话 +``` + +企业解析接口只改善入口、服务发现和品牌配置,不能代替 `{hi}` 的租户绑定。即使 HTTP 解析成功,WebSocket 第一帧仍必须带相同 `tenant_code`。 + +### 0.6 Topic 与产品消息 + +核心命令:`sub` 订阅、`pub` 发送、`get` 拉取、`set` 更新 Topic、`leave` 离开、`del` 删除、`note` 发送回执/临时状态。发送成功为 `{ctrl code:202, params:{seq}}`,服务端下行消息为 `{data}`。 + +所有产品消息在 `pub.head` 中携带: + +```json +{ + "pub": { + "id": "pub-1", + "topic":

+消息类型首版固定为:`text`、`image`、`video`、`voice`、`file`、`contact_card`、`link`、`forward_bundle`、`call`、`system_event`。自定义表情启用后追加 `sticker`。媒体内容只保存 `file_id`、文件元数据和缩略图 ID,不保存可长期绕过鉴权的公共 URL。 + +### 0.7 HTTP 幂等、重试和安全 + +1. 创建、提交、同意、拒绝、删除、转让、收藏、转发等写请求必须携带 `Idempotency-Key`。 +2. GET、断线同步和同幂等键写请求可自动重试;密码、验证码和风控确认只按接口返回的 `retry_after_seconds` 重试。 +3. `401 TOKEN_EXPIRED` 只允许一次静默刷新;刷新失败必须退出登录。`403` 不重试,`429` 按服务端退避。 +4. 服务端必须在最终写入前再次校验好友关系、群角色、禁言、消息归属、文件 ACL、租户配额和风控,不能信任前端按钮状态。 +5. 普通用户禁止向系统 Topic 发布;系统通知必须由服务端受控身份生成。 + +## 1. 账号注册、登录与身份安全 + +### 1.1 企业码登录.png + +企业码登录 + +**状态:新增企业解析接口;WebSocket 租户握手已实现。** + +**当前系统的执行方式:** + +- 前端动作:输入企业码并点击“进入企业”。只去掉首尾空格并校验非空、最长 64

+2. 同一手机号、用户名可以在不同企业分别注册; +3. 单聊、群聊、搜索、文件、Push、系统消息和后台任务均不可跨租户; +4. 租户身份由服务端在握手/认证阶段确定,客户端后续消息不能修改; +5. 现有 `usr...`、`grp...`、`p2p...` Topic 格式尽量保持兼容; +6. 多租户启用后,可以按租户配置功能、配额、认证方式、数据保留和安全策略。 + +## 2. 当前实现为什么不支持多租户 + +### 2.1 认证和 Session 没有租户 + +- `auth.Rec` 只有 `Uid`、`AuthLevel`、有效期、状态等字段,没有 `TenantID`; +- `Session` 只保存 `uid` 和 `authLvl`,登录成功后直接把认证记录写入 Session; +- `MsgClientHi`、`MsgClientLogin` 和 Token 中均没有租户; +- basic 登录名在数据库中全局唯一,手机号/邮箱凭证也全局唯一; +- 密码找回按 `method:value` 全局查找账号; +- root 用户可以通过 `Extra.AsUser` 代表任意用户操作,没有租户范围。 + +这意味着同一手机号无法在两个企业分别注册,也无法证明当前连接属于哪个企业。 + +### 2.2 数据库全部按全局键查询 + +改造前 MySQL schema 版本为 116;第一阶段建立租户主表和握手解析后为 117。除租户主数据表外,核心表仍没有 `tenant_id`: + +| 表 | 当前关键唯一约束 | 多租户问题 | +| --- | --- | --- | +| `users` | `id` | 无租户归属 | +| `auth` | `uname` 全局唯一 | 不同企业不能使用相同登录名 | +| `credentials` | `synthetic` 全局唯一 | 同一手机号不能加入多个企业 | +| `usertags` | 用户/Tag | 搜索可能返回其他企业用户 | +| `devices` | 设备 Hash 全局唯一 | 同一设备上的多企业账号会冲突 | +| `topics` | `name` 全局唯一 | 没有 Topic 租户边界 | +| `subscriptions` | Topic/User | 不能证明用户与 Topic 属于同一租户 | +| `messages` | Topic/SeqId | 查询只按 Topic,没有租户条件 | +| `dellog` | Topic/User | 删除记录没有租户条件 | +| `fileuploads` | File ID | 文件查询和清理没有租户范围 | +| `filemsglinks` | File/Message/Topic/User | 附件关联不能强制同租户 | + +Store/Adapter 的方法也只接收 UID 或 Topic,例如: + +```go +UserGet(uid) +AuthGetUniqueRecord(unique) +TopicGet(topic) +SubscriptionGet(topic, uid, keepDeleted) +MessageGetAll(topic, uid, opts) +FileGet(fileID) +``` + +只在 SQL 表加字段但不修改这些接口,后续开发很容易漏写 `WHERE tenant_id = ?`,仍然会发生越权。 + +### 2.3 内存、集群和系统 Topic 没有租户 + +- Hub 的 `topics` 使用裸 Topic 名作为 `sync.Map` Key; +- 集群一致性哈希只对裸 Topic 名计算; +- `ClusterSess` 和集群 RPC 没有租户字段; +- User Cache 仅以 UID 为 Key; +- Push Receipt、FCM Channel 只有 UID/Topic,没有租户; +- Hub 启动时只初始化一个字面值为 `sys` 的全局系统 Topic; +- 持久化缓存 Key 没有租户命名空间。 + +如果两个租户都使用 `sys` 等逻辑 Topic,同一个内存对象会被共享。即使普通 Topic 名当前由全局 UID 生成,也不能依赖“ID 不碰撞”代替租户授权。 + +### 2.4 文件接口只获得 UID + +`authFileRequest` 当前只返回 UID。文件下载查询只按 File ID,无法把文件访问限制在当前租户。对象存储 Location 也没有统一的租户目录规则。 + +## 3. 关键设计决策 + +### 3.1 目标模式 + +本方案采用: + +> **共享服务集群 + 共享 MySQL 数据库 + 共享表 + 每行 `tenant_id` 强隔离** + +该模式最符合“多企业共用一套平台”的目标,但也是改造面最大的模式。若实际只需要企业数据物理隔离,采用“一企一实例/一企一库”会更简单;它不属于本文的共享多租户实现。 + +### 3.2 用户模型:租户内账号 + +推荐同一个自然人在不同企业中对应不同的 Tinode User: + +```text +手机号 138****0000 + ├─ 租户 A -> user A1 -> 独立好友、群、消息和设置 + └─ 租户 B -> user B1 -> 独立好友、群、消息和设置 +``` + +这样可以最大程度复用当前 User/Topic/Subscription 模型,离职、停用、数据导出和删除也能按企业处理。 + +如果以后需要一个账号切换多个企业,可新增 `global_identities` 和 `tenant_memberships`,把全局身份映射到各租户的本地 User。不要在第一阶段直接把当前 User 改造成跨租户共享主体,否则所有 P2P、资料、设备、未读数和隐私规则都会变得更复杂。 + +### 3.3 ID 策略:保持全局唯一,额外校验租户 + +继续使用现有 Snowflake/加密 UID 生成器,User ID、File ID、普通 Group Topic 名保持全局唯一。外部协议继续使用现有 `usr...`、`grp...`、`p2p...` 格式,不把租户编码暴露在这些 ID 中。 + +所有数据库查询仍必须带 `tenant_id`,原因是: + +- 全局唯一只防止碰撞,不能证明调用者有权访问; +- 已知或泄露的其他租户 ID 仍然可能被直接请求; +- 使用复合租户条件可以让越权请求稳定返回不存在。 + +### 3.4 跨租户通信默认禁止 + +第一阶段规则: + +- 用户搜索只在当前租户; +- P2P 双方必须属于同一租户; +- Group Topic 及全部成员必须属于同一租户; +- 文件、收藏、搜索结果和系统通知不跨租户; +- Tenant Admin 只能管理本租户; +- Platform Admin 的跨租户操作只能走独立后台 API,禁止使用普通客户端协议随意 `AsUser`。 + +未来若需要跨企业协作,应作为“外部联系人/联邦通信”独立设计,使用明确授权、双边租户策略和审计,不能绕过本方案的同租户不变量。 + +## 4. 租户领域模型 + +### 4.1 TenantID 与租户上下文 + +新增强类型,不使用裸字符串在各层传递: + +```go +package types + +type TenantID int64 + +const ZeroTenantID TenantID = 0 + +type TenantContext struct { + TenantID TenantID + ActorUID Uid +} + +type TopicKey struct { + TenantID TenantID + Topic string +} + +type UserKey struct { + TenantID TenantID + UID Uid +} +``` + +`TenantID = 0` 仅允许出现在“尚未完成租户握手”的连接和平台级任务中。任何租户业务 Store 调用发现 `ZeroTenantID` 应立即返回错误,不能自动降级为全局查询。 + +`context.Context` 继续用于超时和取消;租户 ID 应作为显式的强类型参数或租户作用域对象,不能只隐藏在 `context.Value` 中。 + +### 4.2 租户表 + +建议新增: + +```sql +CREATE TABLE im_tenant ( + id BIGINT NOT NULL AUTO_INCREMENT, + code VARCHAR(64) NOT NULL, + name VARCHAR(128) NOT NULL, + tenant_desc VARCHAR(256), + state SMALLINT NOT NULL, + created_at DATETIME(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3), + created_by BIGINT NOT NULL, + updated_at DATETIME(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) ON UPDATE CURRENT_TIMESTAMP(3), + updated_by BIGINT NOT NULL, + PRIMARY KEY (id), + UNIQUE KEY tenants_code (code) +); +``` + +`created_by` 和 `updated_by` 保存操作人用户 ID;系统初始化默认租户时使用 `0` 表示系统操作。 + +当前阶段不在租户主表预留 `config_version` 和 `data_region`。真正建设租户配置中心或多地域路由时,再通过独立的 `tenant_settings` 表增加相应版本/地域字段,避免提前维护没有实际使用场景的列。 + +租户状态建议包括: + +| 状态 | 登录 | 读消息 | 发消息/写业务 | 管理操作 | +| --- | --- | --- | --- | --- | +| `provisioning` | 禁止 | 禁止 | 禁止 | 平台管理员可配置 | +| `active` | 允许 | 允许 | 允许 | 按角色允许 | +| `suspended` | 禁止新登录 | 可配置只读 | 禁止 | 平台管理员可恢复/导出 | +| `deleting` | 禁止 | 禁止 | 禁止 | 仅执行删除任务 | +| `deleted` | 禁止 | 禁止 | 禁止 | 只保留必要审计 | + +### 4.3 租户配置与配额 + +第一阶段只建立 `im_tenant_config`,保存用户数、群数和单群成员数上限。每个租户最多一条配置;三个上限字段为 `0` 时表示不限制。 + +```sql +CREATE TABLE im_tenant_config ( + id BIGINT NOT NULL AUTO_INCREMENT, + tenant_id BIGINT NOT NULL, + max_users BIGINT UNSIGNED NOT NULL DEFAULT 0 COMMENT '0 means unlimited', + max_groups BIGINT UNSIGNED NOT NULL DEFAULT 0 COMMENT '0 means unlimited', + max_group_members INT UNSIGNED NOT NULL DEFAULT 0 COMMENT '0 means unlimited', + created_at DATETIME(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3), + created_by BIGINT NOT NULL, + updated_at DATETIME(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) + ON UPDATE CURRENT_TIMESTAMP(3), + updated_by BIGINT NOT NULL, + PRIMARY KEY (id), + UNIQUE KEY uk_im_tenant_config_tenant_id (tenant_id), + CONSTRAINT fk_im_tenant_config_tenant + FOREIGN KEY (tenant_id) REFERENCES im_tenant(id) + ON DELETE CASCADE +); +``` + +`created_by` 和 `updated_by` 保存操作人用户 ID。系统初始化时可以使用约定的系统操作人 ID;在平台管理员账号模型确定前,暂不为这两个字段建立用户外键。 + +认证、文件、消息频控、功能开关、保留期、合规策略、第三方服务配置及企业品牌等配置本阶段不建字段,待有明确业务需求后再增加。 + +## 5. 租户识别与认证流程 + +### 5.1 推荐流程 + +```mermaid +sequenceDiagram + participant A as App + participant S as Session + participant DB as MySQL + + A->>S: 建立 WebSocket + A->>S: hi(tenant_code) + S->>DB: 按 code 查询租户 + DB-->>S: tenant + S->>S: 校验 active 并固定 TenantID + S-->>A: hi success + 公开租户信息 + A->>S: login(scheme, secret) +``` + +第一阶段不引入 Tenant Resolve API 和 `tenant_ticket`。企业码不是密码,客户端可直接提交;服务端必须查询数据库并只接受 `active` 租户,客户端不能直接提交数据库 TenantID。 + +`tenant_ticket` 的价值在于把一次企业码解析结果变成服务端签名的短期凭证,防止客户端伪造内部 TenantID,并减少 WebSocket 节点的重复查询;它还可以携带目标集群、过期时间和随机数。当前是单集群且刚开始建设,直接查询更简单。以后出现多集群路由或租户解析查询成为性能瓶颈时,可以再增加 ticket,不影响 Session 固定 TenantID 的核心约束。 + +### 5.2 协议修改 + +在 `MsgClientHi` 增加: + +```go +Tenant string `json:"tenant,omitempty"` +``` + +该字段当前直接传企业码,不传数据库 TenantID。规则如下: + +1. 首次 `hi` 必须设置 Tenant; +2. Session 一旦绑定租户,后续 `hi/login/acc/pub/get/set/del/note` 都不能修改; +3. 注册、登录和密码找回前必须已绑定租户; +4. Tenant 缺失、为空或超过 64 个字符时拒绝握手,不做默认租户兼容; +5. 租户不存在时返回 404,租户不是 `active` 状态时返回 403; +6. 服务端返回的租户信息仅包含 `code` 和 `name`,不返回内部 ID、状态或密钥。 + +当前已实现 `MsgClientHi.Tenant`、MySQL 按企业码查询、Session TenantID 固定、租户公开信息响应,以及未绑定租户时拒绝后续命令。认证器和业务表尚未带 TenantID,因此当前代码只是租户识别基础,不能视为已经完成数据隔离。 + +后续 HTTP API 的 TenantID 必须从租户化签名 Token 中获得。禁止只信任 URL、Header 或请求 Body 中客户端自报的 `tenant_id`。 + +### 5.3 认证接口修改 + +当前认证器接口: + +```go +Authenticate(secret []byte, remoteAddr string) +``` + +建议改为: + +```go +type AuthContext struct { + TenantID types.TenantID + RemoteAddr string +} + +Authenticate(ctx AuthContext, secret []byte) +``` + +`auth.Rec` 增加: + +```go +TenantID types.TenantID `json:"tenant_id,omitempty"` +``` + +basic、REST、code、token 等认证器和所有 Mock 必须同步修改。认证器返回 TenantID 与 Session 不一致时,统一按认证失败处理,并写安全审计。 + +### 5.4 登录名和凭证的租户唯一性 + +数据库约束修改为: + +```text +auth: UNIQUE (tenant_id, uname) +auth: UNIQUE (tenant_id, userid, scheme) +credentials: UNIQUE (tenant_id, synthetic) +devices: UNIQUE (tenant_id, hash) +``` + +这样同一手机号可以分别加入多个企业。密码找回必须先有 TenantContext,再按 `(tenant_id, method, value)` 查找,不能全库搜索手机号后选择第一个用户。 + +### 5.5 Token v2 + +当前 HMAC Token 固定包含 UID、过期时间、认证级别、序列号和特性位,没有 TenantID。需要新增带版本的 Token v2: + +```text +[version][tenant_id][uid][expires][auth_level][serial][features][signature] +``` + +Token 规则: + +1. v2 Token 的签名覆盖 TenantID; +2. Token 认证返回 `TenantID + UID`; +3. Session 已绑定租户时必须与 Token 一致; +4. 不包含 TenantID 的 Token 一律拒绝; +5. 租户停用时应支持按租户 Token 版本或撤销时间拒绝已签发 Token,不能只能全平台提升 serial。 + +### 5.6 管理员模型 + +当前 `AuthLevel` 只有 NONE、ANON、AUTH、ROOT,不足以表达租户管理员。建议保留认证级别,同时增加业务角色: + +- `platform_admin`:平台级租户生命周期和运维; +- `tenant_owner`:本租户最高管理员; +- `tenant_admin`:组织、用户、群和安全管理; +- `security_auditor`:实名、举报、审计读取; +- 普通用户。 + +Tenant Admin 的权限必须绑定 TenantID。普通 WebSocket 的 `Extra.AsUser` 只能在同租户且有明确授权时使用;平台管理员跨租户代操作应走隔离的后台 API、二次验证和完整审计。 + +## 6. Session、消息和 Topic 改造 + +### 6.1 Session + +`Session`、`ClusterSess` 增加: + +```go +tenantID types.TenantID +``` + +需要建立以下不变量: + +```text +已认证 Session: +session.tenantID != 0 +session.uid != 0 +User(session.uid).tenant_id == session.tenantID +``` + +所有内部 `ClientComMessage` 和 `ServerComMessage` 应携带服务端写入的 TenantID,序列化给普通客户端时不必暴露。插件、集群和后台任务可以读取,但不得覆盖。 + +### 6.2 内部路由键 + +外部 Topic 名保持不变,内部统一使用: + +```go +func (k TopicKey) RoutingKey() string { + return strconv.FormatUint(uint64(k.TenantID), 10) + ":" + k.Topic +} +``` + +需要修改: + +- Hub `topicGet/topicPut/topicDel`; +- Session 的订阅 Map; +- Topic Proxy 和 Multiplex Session Key; +- 集群一致性哈希 `nodeForTopic/isRemoteTopic`; +- ClusterReq、ClusterRoute、ClusterResp; +- Topic 重哈希和代理失效; +- 调试端点中显示的 Topic 标识。 + +客户端仍看到原始 Topic 名,只有服务端内部使用 RoutingKey。不要直接把 `tenantID:` 前缀写入数据库 Topic 名或回传客户端,否则会破坏 Topic 类别解析、P2P 解析和现有客户端。 + +### 6.3 `sys`、`me`、`fnd`、`slf` + +- `me`、`fnd`、`slf` 虽由全局 UID 派生,仍必须使用 Session TenantID 加载; +- 全局字面值 `sys` 必须改为“租户作用域内的逻辑别名”; +- Hub 不再启动一个全局 `sys` Topic;应在租户首次使用或租户创建时初始化 `(tenant_id, sys)`; +- 系统消息生产者必须指定 TenantID,不能广播到全平台 `sys`; +- `fnd` 搜索只读取当前租户 Tags; +- `slf` 收藏不能引用其他租户的源消息或文件。 + +### 6.4 P2P + +P2P Topic 名仍由两个全局 UID 生成,但创建前必须执行: + +```text +initiator.tenant_id == invited.tenant_id == session.tenant_id +``` + +订阅、发送、读取、删除和通话时都继续带 TenantID 查询,避免通过已知 P2P 名访问其他企业。 + +### 6.5 群聊 + +创建 Group Topic 时由 Session 注入 TenantID。邀请、审批、管理员变更和群主转让必须验证: + +- Topic 属于当前租户; +- 操作者属于当前租户; +- 目标成员属于同一租户; +- 所有写入的 Subscription 使用同一 TenantID; +- Outbox 和系统通知也使用相同 TenantID。 + +不要接受客户端在 `set.desc`、Aux 或 Tags 中提交的 tenant 字段作为授权依据。 + +## 7. Store 与 Adapter 改造 + +### 7.1 不推荐只靠 `context.Value` + +租户条件应进入编译期可见的接口。推荐增加租户作用域 Store: + +```go +tenantStore := store.ForTenant(session.tenantID) + +user, err := tenantStore.Users.Get(uid) +topic, err := tenantStore.Topics.Get(topicName) +msgs, err := tenantStore.Messages.GetAll(topicName, uid, opts) +``` + +底层 Adapter 接口显式接收 TenantID: + +```go +UserGet(tenantID, uid) +AuthGetUniqueRecord(tenantID, unique) +TopicGet(tenantID, topic) +SubscriptionGet(tenantID, topic, uid, keepDeleted) +MessageGetAll(tenantID, topic, uid, opts) +FileGet(tenantID, fileID) +``` + +`store.ForTenant(ZeroTenantID)` 必须失败。平台级扫描和租户生命周期操作使用单独的 `PlatformStore` 接口,不能给业务代码一个可省略 TenantID 的全局 Store。 + +### 7.2 需要修改的 Store 接口范围 + +| 接口域 | 必须租户化的操作 | +| --- | --- | +| Users | Create/Get/GetAll/Update/Delete/State/Tags/Topics/Subs/Unread | +| Auth | Add/Get/Update/Delete/Unique lookup | +| Credentials | Upsert/Get/Confirm/Fail/Delete/Reset lookup | +| Topics | Create/Get/Share/Delete/Update/Owner/Find | +| Subscriptions | Create/Get/Update/Delete/按 User/Topic 查询 | +| Messages | Save/Get/Delete/GetDeleted/更新 Topic SeqId | +| Devices | Upsert/Get/Delete/Push Channel | +| Files | Start/Finish/Get/Link/DeleteUnused/Access check | +| Persistent Cache | Get/Upsert/Delete/Expire | + +这会修改 `server/store/store.go`、`server/db/adapter.go`、MySQL Adapter、Mock Store 以及大量调用点。不要为了减少改动只改少数查询;任何保留的无租户业务接口都会成为后续越权入口。 + +### 7.3 数据库支持范围 + +当前仓库还有 PostgreSQL、MongoDB、RethinkDB Adapter。多租户改造会使公共 Adapter 接口整体变化。 + +推荐产品版第一阶段明确只支持 MySQL: + +- MySQL 完成多租户 schema 和全部集成测试; +- 其他 Adapter 编译时可使用明确的 `ErrUnsupportedTenant` 或从产品构建中排除; +- 不能让未实现多租户过滤的 Adapter 在配置错误时继续启动; +- 如果必须继续支持四种数据库,应将工作量视为四套独立实现和隔离验收。 + +## 8. MySQL Schema 改造 + +### 8.1 统一规则 + +1. 所有租户业务表增加 `tenant_id BIGINT NOT NULL`; +2. 唯一索引和高频查询索引以 `tenant_id` 作为第一列; +3. 子表使用 `(tenant_id, parent_id)` 复合外键,防止跨租户关联; +4. `kvmeta` 中数据库 schema 版本属于平台级元数据,不加 TenantID; +5. 持久化业务缓存使用 TenantID 列或强制租户 Key 前缀; +6. 所有删除、更新、聚合和后台批处理同样带 TenantID; +7. MySQL 没有可直接依赖的应用级 RLS,隔离责任主要在 Adapter 和复合约束。 + +### 8.2 核心表与索引 + +| 表 | 新增列 | 主要索引调整 | +| --- | --- | --- | +| `users` | `tenant_id` | `UNIQUE(tenant_id,id)`;状态/最近登录索引前加 tenant | +| `usertags` | `tenant_id` | `INDEX(tenant_id,tag)`;`UNIQUE(tenant_id,userid,tag)` | +| `devices` | `tenant_id` | `UNIQUE(tenant_id,hash)`;复合外键到 users | +| `auth` | `tenant_id` | `UNIQUE(tenant_id,uname)`;`UNIQUE(tenant_id,userid,scheme)` | +| `topics` | `tenant_id` | `UNIQUE(tenant_id,name)`;Owner/State 索引前加 tenant | +| `topictags` | `tenant_id` | `INDEX(tenant_id,tag)`;`UNIQUE(tenant_id,topic,tag)` | +| `subscriptions` | `tenant_id` | `UNIQUE(tenant_id,topic,userid)`;User/Topic 查询前加 tenant | +| `messages` | `tenant_id` | `UNIQUE(tenant_id,topic,seqid)`;历史查询索引前加 tenant | +| `dellog` | `tenant_id` | Topic/User/DelId 索引前加 tenant | +| `credentials` | `tenant_id` | `UNIQUE(tenant_id,synthetic)`;User/Method 索引前加 tenant | +| `fileuploads` | `tenant_id` | `INDEX(tenant_id,status,updatedat)`;复合用户归属 | +| `filemsglinks` | `tenant_id` | File/Message/Topic/User 索引及复合外键全部带 tenant | + +Topic 名当前通常全局唯一,但仍把数据库唯一约束改为 `(tenant_id, name)`,这样各租户可以拥有自己的逻辑 `sys`,也让 schema 明确表达隔离边界。 + +### 8.3 业务表 + +后续新增的所有 `im_*` 表,包括好友、群审批、组织、会议、日报、举报、Outbox、审计和消息索引,必须从第一版就包含 TenantID。禁止先以全局表上线再补租户。 + +推荐所有 Repository 方法使用如下形态: + +```text +Get(tenantID, id) +List(tenantID, filter, cursor) +Create(tenantID, actorID, data) +Update(tenantID, id, expectedVersion, data) +Delete(tenantID, id) +``` + +### 8.4 SQL 示例 + +认证查询: + +```sql +SELECT userid, secret, expires, authlvl +FROM auth +WHERE tenant_id = ? AND uname = ?; +``` + +Topic 查询: + +```sql +SELECT ... +FROM topics +WHERE tenant_id = ? AND name = ? AND state <> ?; +``` + +消息查询: + +```sql +SELECT ... +FROM messages +WHERE tenant_id = ? AND topic = ?

Push、插件和外部服务 + +### 12.1 Push + +`push.Receipt`、`ChannelReq` 和 `Payload` 内部增加 TenantID。要求: + +- 设备查询使用 `(tenant_id, uid)`; +- FCM Topic/Channel 名加入不可碰撞的租户前缀; +- 租户级 Push 模板、应用包和凭证由服务端配置选择; +- Push Handler 日志不可输出其他租户的设备 Token; +- 未读数 Cache 使用 Tenant User Key; +- 锁屏正文按租户安全策略生成。 + +如果不同租户使用不同品牌 App,Push Handler 需要根据 TenantID 选择 FCM/APNS 凭证,不能继续假定一套全局凭证。 + +### 12.2 Plugin Firehose + +Plugin 请求增加 TenantID、租户策略版本和不可伪造的上下文。插件返回 `REPLACE` 时服务端必须保留原 TenantID,禁止插件把消息换到其他租户/Topic。 + +插件配置分两类: + +- 平台级统一审核服务; +- 租户级专属审核服务。 + +无论哪种,调用超时、熔断、失败开放/关闭策略都按租户配置,审计和指标带 TenantID。 + +### 12.3 REST 认证、短信、TURN 和对象存储 + +外部请求必须携带服务端签名的租户上下文,并对回调结果校验 TenantID。租户自带密钥时,通过密钥管理系统按 TenantID 选择,不把 Secret 缓存在普通 Topic/User JSON 中。 + +## 13. API Key、限流和配额 + +当前 `X-Tinode-APIKey` 是应用级准入凭证。多租户后建议保持以下职责: + +- API Key:识别客户端应用、平台、版本和是否允许连接; +- Tenant Ticket/Token:确定租户; +- User Token:确定租户内用户; +- Role/Policy:确定具体操作权限。 + +不要仅通过 API Key 推导 Tenant,因为同一个 App 可能登录多个企业。若某企业使用专属 App,可额外把 API Key 限定到一个 Tenant,但仍需验证 Token Tenant 一致。 + +限流 Key 至少包含: + +```text +tenant + endpoint/action +tenant + uid + action +tenant + ip + action +``` + +配额计数包括用户、Topic、消息速率、文件大小、总存储、会议/报告等。超限返回稳定业务错误并记录租户审计,不能让一个大租户耗尽全平台队列。 + +## 14. 日志、指标与审计 + +### 14.1 日志和 Trace + +认证后所有请求日志增加: + +```text +request_id, tenant_id, uid, sid, topic, action, result +``` + +手机号、证件号、Token、企业码密钥和文件签名不写日志。TenantID 可写内部数值或不可逆短标识。 + +### 14.2 指标 + +租户 ID 直接作为 Prometheus Label 可能造成高基数。建议: + +- 平台指标默认不带 Tenant Label; +- 关键配额和 SLA 写入租户用量表或专用统计系统; +- 仅对白名单大租户暴露租户级指标; +- 错误日志和 Trace 保留 TenantID 供定位。 + +### 14.3 审计 + +以下操作必须记录 TenantID: + +- 租户创建、停用、恢复和删除; +- Tenant Admin 授权和代操作; +- 用户停用、离职和数据导出; +- 群主/管理员变更; +- 实名审核、举报处置、匿名信箱读取; +- 文件下载、批量导出和搜索敏感内容; +- 平台管理员跨租户操作。 + +审计表只允许追加,普通租户管理员不能修改或删除。 + +## 15. 测试方案 + +### 15.1 单元和接口测试 + +- TenantContext 不可为空; +- Session 只能绑定一次 Tenant; +- Token Tenant 与 Session Tenant 不一致时登录失败; +- Store/Adapter 不提供无 Tenant 的业务查询; +- TopicKey、UserKey、CacheKey 和 Push Channel 正确命名空间化; +- Plugin 不能替换 Tenant; +- Platform Admin 与 Tenant Admin 权限边界正确。 + +### 15.2 MySQL 集成测试 + +创建 Tenant A、Tenant B,并使用相同用户名、手机号、群显示名和逻辑 `sys`。至少覆盖: + +| 场景 | 预期 | +| --- | --- | +| 两租户注册相同用户名/手机号 | 均成功,各自登录到不同 UID | +| A 使用 B 的账号密码登录 | 统一认证失败 | +| A 已知 B 的 UID 执行 Get/Set/Delete | NotFound/Denied,不返回存在性 | +| A 已知 B 的 Group Topic 订阅或发布 | 拒绝且不加载到 A 的 Hub Cache | +| A 邀请 B 用户进入 A 群 | 拒绝,无 Subscription 写入 | +| A 已知 B 的 Message Topic/SeqId | 不能读取、搜索、删除或收藏 | +| A 已知 B 的 File ID/URL | 不能下载、关联或转发 | +| A/B 同时使用 `sys` | 只收到本租户系统消息 | +| A 停用用户 | 不影响相同设备上的 B 用户 | +| A Tenant Admin `AsUser` B 用户 | 拒绝并审计 | +| 同一设备在 A/B 注册 Push | 设备记录和 Push 不串租户 | +| A 大量任务积压 | B 的通知和文件 GC 不被长期饿死 | + +### 15.3 集群测试 + +- 相同 Topic 别名在不同 Tenant 生成不同 RoutingKey;

+2. 核心表和全部业务表 TenantID 为 NOT NULL; +3. Auth、Credential、Device、Topic 和 Subscription 唯一约束已租户化; +4. Token v2、Session Tenant 和 HTTP Principal 全链路一致; +5. Hub、User Cache、Cluster、Push、Plugin 和 Persistent Cache 均携带 Tenant; +6. `sys` 已按租户隔离; +7. 文件下载和搜索完成租户过滤及 ACL 二次校验; +8. 双租户自动化测试、集群测试和安全测试全部通过; +9. 所有运行节点和后台任务均为租户感知版本; +10. 内部第二租户稳定运行后,才允许创建真实第二企业。 + +## 20. 最终建议 + +多租户改造必须被视为服务端基础架构改造,而不是“给 users/topics/messages 加一列”。当前代码的认证、Store 接口、Hub Cache、Cluster、系统 Topic、文件和 Push 都使用全局 UID/Topic 语义,任何一处遗漏都可能造成跨企业数据泄露。 + +建议采用租户内独立 User、全局唯一 UID、共享表 `tenant_id` 强隔离的方案。全新数据库从创建时就使用最终多租户 Schema,并在 Store、认证、Token、路由、缓存、文件和 Push 全链路强制 TenantID;所有负向测试通过后,再开启真实租户。 + +工程上最重要的控制手段是:让 TenantID 进入类型和方法签名,使遗漏租户条件尽量在编译或测试阶段暴露;平台级全局查询使用隔离接口,普通业务代码永远只能获得 `store.ForTenant(...)`。这样才能让后续好友、群治理、企业工作台、搜索和安全业务从一开始就在正确的隔离边界内建设。 diff --git a/docs/IM-现有实现与新需求差异对照总结.md b/docs/IM-现有实现与新需求差异对照总结.md new file mode 100644 index 0000000..b1edc27 --- /dev/null +++

+废弃项不要直接删除,应按以下顺序执行: + +1. 在配置和对接文档中标记 deprecated,禁止新客户端接入; +2. 为废弃入口增加调用指标,至少观察一个完整客户端版本周期; +3. 对匿名账号、邮箱账号、Channel 等有数据的能力先做存量扫描; +4. 给存量用户提供迁移方案,例如邮箱账号绑定手机号、Channel 迁移普通群; +5. 新版本服务端默认关闭,保留临时回退开关; +6. 确认无调用和无未迁移数据后,再删除路由、配置、代码和测试; +7. 数据库删除列或表必须单独发布,保留备份和回滚窗口。 + +客户端 gRPC 和 Plugin gRPC 必须分开处理:新需求没有客户端 gRPC,因此前者废弃;第 11 章需要外部审核插件,因此 Plugin Firehose 及其 gRPC 通道保留。 + +## 11. 验收口径 + +每项改造只有同时满足以下条件才算完成: + +1. 文档中的新需求章节有对应 API/协议、数据表和权限规则; +2. 旧客户端兼容行为有明确结论,不依赖未定义 JSON 字段; +3. 重试、并发、断网恢复不会产生重复业务数据; +4. 用户不能通过直接构造协议绕过好友、黑名单、禁言、隐私和青少年策略; +5. 文件、搜索、转发和收藏均重新执行当前用户的资源权限; +6. 共享 SaaS 模式下通过跨租户负向测试; +7. 审批、实名、举报、群管理和匿名信箱敏感操作有审计记录; +8. 废弃入口有调用量证据和存量迁移结果,不能仅凭新原型没有页面就直接删除; +9. MySQL schema、升级脚本、回滚脚本和代码中的建表定义保持一致; +10. 服务端单元测试、MySQL 集成测试、WebSocket/HTTP 端到端测试和真实设备通话测试全部通过。 + +## 12. 最终处理建议 + +新系统应保留 Tinode 的实时消息内核,重点修改认证流程、消息协议、权限策略、文件授权和通话状态;好友、群治理、搜索、企业工作台、实名、青少年和举报作为新的产品业务层建设。 + +新需求未覆盖的匿名登录、邮箱注册验证、Channel、Long Poll、客户端 gRPC、示例聊天机器人和静态网页托管标记为废弃。多数据库 Adapter 是否物理删除取决于产品数据库决策;若产品版确定只支持 MySQL,则 PostgreSQL、MongoDB 和 RethinkDB 不再承担新业务适配与验收。 + +改造顺序应先处理租户、消息幂等和文件授权,再完成好友与基础消息,随后完成群治理、搜索、通话与安全,最后建设企业工作台。这样可以最大限度复用现有实现,同时避免继续维护新产品不需要的入口和功能。 diff --git a/docs/IM-系统设计文档.md b/docs/IM-系统设计文档.md new file mode 100644 index 0000000..6730762 --- /dev/null +++ b/docs/IM-系统设计文档.md @@ -0,0 +1,898 @@ +# IM 系统设计文档 + +> 版本:v1.1

+编辑、撤回与索引更新必须使用乐观版本控制。请求携带期望 `version`,版本不一致返回冲突错误,客户端重新拉取当前消息状态。 + +### 8.5 内容审核时序 + +发送链路先执行本地权限、限频和硬规则,再按租户及消息类型选择以下一种审核模式: + +| 模式 | 处理方式 | 适用场景 | +| --- | --- | --- | +| `sync_block` | 在短超时内同步审核,通过后持久化和广播;超时按租户配置拒绝或降级 | 高风险文本、小请求 | +| `async_hold` | 以 `pending_review` 持久化但不广播;Outbox 审核通过后发布,拒绝后标记 `rejected` | 文件、图片和高风险内容 | +| `async_post_audit` | 先发布,异步审核;命中后执行系统撤回并审计 | 租户明确允许的低风险内容 | + +状态转换固定为: + +```text +pending_review -> approved -> published +pending_review -> rejected +published -> recalled_by_review +``` + +客户端提交的审核状态一律忽略。审核 Worker 必须幂等,同一消息只能完成一次终态转换。 + +## 9. 好友与黑名单设计 + +好友关系是单聊产品状态的真源,不直接用 P2P Topic 是否存在表示好友。 + +### 9.1 好友申请与关系状态 + +```mermaid +stateDiagram-v2 + [*] --> none + none --> requested: 发起申请 + requested --> accepted: 通过 + requested --> rejected: 拒绝 +

记录申请状态,`im_friendships` 记录双方好友关系,`im_user_blocks` 记录单向拉黑。拉黑不修改好友关系状态;取消拉黑只删除当前用户的黑名单记录,不自动恢复已经删除的好友关系。 + +### 9.2 服务端规则 + +1. 申请、同意、拒绝、删除、拉黑必须幂等。 +2. 好友申请保存验证留言、来源、过期时间和处理人。 +3. 拉黑是单向行为,唯一约束为 `(tenant_id, blocker_id, blocked_id)`;被拉黑人发消息、通话、名片、查看资料时按策略阻断。 +4. 删除好友后历史消息默认保留,但双方不能继续发送好友消息。 +5. 好友资料字段由关系和隐私设置共同决定。 +6. 接受申请必须在一个事务内更新申请、创建好友关系、创建或激活 P2P Topic/Subscription,并写入 Outbox。 +7. 单聊策略按“双方账号有效 -> 好友关系有效 -> 任一方向黑名单 -> 隐私/青少年/风控”的顺序判定。 + +## 10. 群治理设计 + +现有 Group Topic 继续作为群消息容器。`im_group_settings` 与 `im_group_members` 是群业务状态真源;Topic、Subscription 和 ACL 是通信内核投影。所有成员和角色变化必须通过产品业务接口完成,并在同一 MySQL 事务内同步业务真源与通信投影。 + +### 10.1 群角色 + +| 角色 | 业务真源 | 通信投影 | 权限 | +| --- | --- | --- | --- | +| 群主 | `im_group_settings.owner_user_id` +

`tenant_id`、Topic、SeqId、消息类型、发送人、时间、规范化检索文本和资源元数据,返回前二次校验 ACL。 +3. 文件/图片/视频/链接搜索:依赖消息类型索引和文件元数据索引。 + +首期固定使用 MySQL 8:结构化条件使用 B-Tree 复合索引,消息正文使用独立 `im_message_index.search_text` 和适合中文的 FULLTEXT/ngram 索引。分页游标使用稳定的 `created_at + message_id`,不能使用大 Offset。 + +搜索索引不是授权来源。查询必须先限定 `tenant_id` 和当前用户可读 Topic 集合,返回前再次校验 Topic Read ACL、成员状态、用户侧删除、全员撤回和审核状态。退群、拉黑或权限变更后必须立即阻断查询,即使异步索引尚未删除。 + +出现以下任一情况时重新评估 OpenSearch/Elasticsearch:单租户可检索消息达到千万级、MySQL 搜索 P95 超过 500ms、需要复杂中文相关性/高亮,或索引写入明显影响消息主库。切换时保持 HTTP 搜索契约不变。 + +## 12. 通话设计 + +现有 P2P WebRTC 信令继续复用,新增业务通话记录。 + +### 12.1 通话状态 + +```mermaid

外部风控插件”共同组成: + +1. 本地规则用于稳定阻断和提示,例如陌生人、敏感词、频繁加好友、异常文件。 +2. 外部插件用于内容审核、风险评分和策略建议。 +3. 插件调用遵守第 8.5 节的三种审核模式、超时和降级规则,不能在 Topic Actor 中执行无界远程等待。 +4. 风险提示和二次确认结果写审计。 + +### 15.3 举报与反馈 + +举报和反馈都按工单处理。 + +| 类型 | 特点 | +| --- | --- | +| 举报 | 绑定被举报对象、会话、消息、原因、证据和处理状态 | +| 意见反馈 | 绑定提交人、设备、版本、问题描述、附件和处理状态 | + +举报证据应固化消息快照和文件引用,防止原消息删除后无法处理。 + +## 16. 系统消息与通知设计 + +需要产生异步副作用的业务状态变化,在同一数据库事务中写入 Outbox,由 Worker 生成系统消息、Push、索引或定时任务。没有异步副作用的更新不要求创建空事件。 + +### 16.1 系统消息格式 + +系统消息固定使用以下结构;业务模块只能登记 `event_type` 和参数 Schema,不能自行定义另一套消息信封: + +```json +{ + "type": "system", + "event_type": "group_join_approved", + "template_version": 1, + "actor_id": "usr...", + "target_ids": ["usr..."], + "params": { + "group_id": "grp...", + "group_name": "项目群" + }, + "dedupe_key": "tenant:1:group:grpxxx:join:request123" +} +``` + +### 16.2 事件类型 + +首期至少定义: + +| 业务 | 事件 | +| --- | --- | +| 账号安全 | 新设备登录、密码修改、实名提醒 | +| 好友 | 新申请、通过、拒绝、删除 | +| 群 | 邀请、申请、审批、公告、禁言、管理员变更、群主转让、解散 | +| 文件 | 群文件上传、文件失效 | +| 通话 | 未接、拒绝、取消、忙线、通话结束 | +| 工作台 | 会议通知、会议变更、日报提醒、月报提醒、信箱处理 | +| 安全 | 反诈提示、举报受理、反馈受理 | + +## 17. 权限模型 + +### 17.1 角色层级 + +| 层级 | 角色 | +| --- | --- | +| 平台 | `platform_admin` | +| 租户 | `tenant_owner`、`tenant_admin` | +| 组织 | 部门负责人、报表管理员 | +| 群 | 群主、管理员、成员 | +| 关系 | 好友、非好友、黑名单 | +| 账号 | 普通用户、实名用户、青少年模式用户 | + +### 17.2 权限判定顺序 + +```text +租户状态 -> 用户状态 -> 业务角色 -> Topic ACL -> 产品策略 -> 风控策略 +``` + +任何一步失败,写操作不得继续。 + +## 18. 数据一致性与异步任务 + +### 18.1 事务边界 + +必须在同一事务中完成: + +1. 好友申请处理和关系状态更新。 +2. 群审批通过和 Subscription 写入。 +3. 群主转让和权限更新。 +4. 消息保存和附件引用建立。 +5. 文件记录从 `uploaded` 切换为 `ready`、附件引用和业务索引写入。 +6. 举报提交和证据引用。 + +业务层不能在 Handler 中连续调用多个独立 Store 方法来模拟事务。`imstore` 必须提供按用例划分的事务方法,例如 `AcceptFriendRequest`、`ApproveGroupJoin`、`TransferGroupOwner` 和 `SaveMessageWithAttachments`,方法内部同时更新产品业务表、Tinode 核心表、审计记录和 Outbox。 + +对象存储不参与 MySQL 事务,文件采用以下状态机: + +```text +pending -> uploaded -> ready +pending/uploaded -> failed +uploaded(超时且无引用) -> orphaned -> deleted +``` + +对象上传成功后,再在 MySQL 事务中把文件切换为 `ready` 并建立业务引用。若数据库事务失败,文件保持 `uploaded`,由带宽受控的租户级垃圾回收任务清理;消息只能引用 `ready` 文件。 + +### 18.2 Outbox + +需要通知、Push、索引或审计的业务写操作,在事务内写入 `im_outbox_events`。异步 Worker 负责: + +1. 发送系统消息。 +2. 推送离线通知。 +3. 更新搜索索引。 +4. 调用外部审核/反诈。 +5. 发送会议、日报、月报定时提醒。 +6. 记录可观测指标。 + +`im_outbox_events` 至少包含: + +```text +id, tenant_id, aggregate_type, aggregate_id, event_type, +payload, dedupe_key, state, available_at, attempts, +locked_by, locked_at, last_error, created_at, processed_at +``` + +Outbox 处理规则: + +1. `dedupe_key` 在租户内唯一,生产事件和消费副作用都必须幂等。 +2. Worker 使用 `SELECT ... FOR UPDATE SKIP LOCKED` 分批领取事件,设置最大批量和租户公平调度,避免单个租户占满队列。 +3. 失败采用有上限的指数退避;超过上限进入 `dead_letter`,触发告警并支持人工重放。 +4. 系统消息通过集群安全的内部发布接口进入目标 Topic,不能直接假设 Outbox Worker 与目标 Topic 位于同一进程。 +5. 标记事件成功前必须确认目标副作用已获得稳定幂等结果;进程崩溃后的重复执行不得产生重复消息或 Push。 +6. 外部审核事件必须按第 8.5 节推进消息审核状态,不能绕过状态机直接广播。 + +## 19.

The intent of Drafty is to be expressive just enough without opening too many possibilities for security issues. One may think of it as JSON-encapsulated [markdown](https://en.wikipedia.org/wiki/Markdown). Drafty is influenced by FB's [draft.js](https://draftjs.org/) specification. As of the time of this writing [Javascript](https://github.com/tinode/tinode-js/blob/master/src/drafty.js), [Java](https://github.com/tinode/tindroid/blob/master/tinodesdk/src/main/java/co/tinode/tinodesdk/model/Drafty.java) and [Swift](https://github.com/tinode/ios/blob/master/TinodeSDK/model/Drafty.swift) implementations exist. A [Go implementation](https://github.com/tinode/chat/blob/master/server/drafty/drafty.go) can convert Drafy to plain text and previews. + +## Example + +> this is **bold**, `code` and _italic_, ~~strike~~

In general, a valid Drafy may contain just the `txt` field. + +### Inline Formatting `fmt` + +Inline formatting is an array of individual styles in the `fmt` field. Each style is represented by an object with at least `at` and `len` fields. The `at` value means 0-based offset into `txt`, `len` is the number of characters to apply formatting to. The third value of style is either `tp` or `key`. + +If `tp` is provided, it means the style is a basic text decoration: + * `BR`: line break. + * `CO`: code or monotyped text, possibly with different background: `monotype`. + * `DL`: deleted or strikethrough text: ~~strikethrough~~. + * `EM`: emphasized text, usually represented as italic: _italic_. + * `FM`: form / set of fields; may also be represented as an entity. + * `HD`: hidden content. + * `HL`: highlighted text, such as text in a different color or with a different background; the color cannot be specified. + * `RW`: logical grouping of formats, a row; may also be represented as an entity. + * `ST`: strong or bold text: **bold**. + +If key is provided, it's a 0-based index into the `ent` array which contains extended style parameters such as an image or an URL: + * `AU`: embedded audio. + * `BN`: interactive button. + * `EX`: generic attachment. + * `FM`: form / set of fields; may also be represented as a basic decoration. + * `HT`: hashtag, e.g. [#hashtag](#). + * `IM`: inline image. + * `LN`: link (URL) [https://api.tinode.co](https://api.tinode.co). + * `MN`: mention such as [@tinode](#). + * `RW`: logical grouping of formats, a row; may also be represented as a basic decoration. + * `VC`: video (and audio) calls. + * `VD`: inline video. + +Examples: + * `{ "at":8, "len":4, "tp":"ST"}`: apply formatting `ST` (strong/bold) to 4 characters starting at offset 8 into `txt`. + * `{ "at":144, "len":8, "key":2 }`: insert entity `ent[2]` into position 144, the entity spans 8 characters. + * `{ "at":-1, "len":0, "key":4 }`: show the `ent[4]` as a file attachment, don't apply any styling to text. + +The clients should be able to handle missing `at`, `key`, and `len` values. Missing values are assumed to be equal to `0`. + +The indexes `at` and `len` are measured in [Unicode code points](https://developer.mozilla.org/en-US/docs/Glossary/Code_point), not bytes or characters. The behavior of multi-codepoint glyphs such as emojis with Fitzpatrick skin tone modifiers, variation selectors, or grouped with `ZWJ` is currently undefined. + +#### `FM`: a form, an ordered set or fields + +Form provides means to add paragraph-level formatting to a logical group of elements. It may be represented as a text decoration or as an entity. + + + + +
Do you agree?
Yes
No

An `"su": true` indicates that the form is `single use`: the form should change after the first interaction to show that it's no longer accepting input. + +### Entities `ent` + +In general, an entity is a text decoration which requires additional (possibly large) data. An entity is represented by an object with two fields: `tp` indicates type of the entity, `data` is type-dependent styling information. Unknown fields are ignored. + +#### `AU`: embedded audio record +`AU` is an audio record. The `data` contains the following fields: +```js +{ + "tp": "AU", + "data": { + "mime": "audio/aac", + "val": "Rt53jUU...iVBORw0KGgoA==", + "ref": "/v0/file/s/e769gvt1ILE.m4v", + "preview": "Aw4JKBkAAAAKMSM...vHxgcJhsgESAY" + "duration": 180000, + "name": "ding_dong.m4a", + "size": 595496 + } +} +``` + * `mime`: data type, such as 'audio/ogg'. + * `val`: optional in-band audio data: base64-encoded audio bits. + * `ref`: optional reference to out-of-band audio data. Either `val` or `ref` must be present. + * `preview`: base64-encoded array of bytes to generate a visual preview; each byte is an amplitude bar. + * `duration`: duration of the record in milliseconds. + * `name`: optional name of the original file. + * `size`: optional size of the file in bytes. + +To create a message with just a single audio record and no text, use the following Drafty: +```js +{ + txt: " ", + fmt: [{len: 1}], + ent: [{tp: "AU", data: {}]} +} +``` + +_IMPORTANT Security Consideration_: the `val` and `ref` fields may contain malicious payload. The client should restrict URL scheme in the `ref` field to `http` and `https` only. The client should present content of `val` field to the user only if it's correctly converted to an audio. + + +#### `BN`: interactive button +`BN` offers an option to send data to a server, either origin server or another one.

+**A**: 日志在容器内的 `/var/log/tinode.log`。使用以下命令附加到运行中的容器: +``` +docker exec -it name-of-the-running-container /bin/bash +``` +然后,例如用 `tail -50 /var/log/tinode.log` 查看日志。 + +如果容器已停止,可以从容器复制日志(保存到 `./tinode.log`): +``` +docker cp name-of-the-container:/var/log/tinode.log ./tinode.log +``` + +或者,可以通过将主机目录映射到容器内的 `/var/log/`,让 Docker 容器将日志保存到主机目录。在 `docker run` 命令中添加 `-v /where/to/save/logs:/var/log`。 + + +### Q: 启用推送通知有哪些选项?
+**A**: 可以使用 [Tinode Push Gateway (TNPG)](https://github.com/tinode/chat/tree/master/server/push/tnpg) 或 [Google FCM](https://firebase.google.com/docs/cloud-messaging): + * _Tinode Push Gateway_ 使用 Tinode 服务器代您发送推送。需要最少的设置:您的服务器向 TNPG 发送请求,TNPG 转发给 Google FCM 或 Apple APNS。 + * _Google FCM_ 不依赖 Tinode 基础设施推送,但需要您构建和发布自己的移动应用(iOS 和 Android)。 + + +### Q: 如何使用 Tinode Push Gateway 设置推送通知?
+**A**: 启用 TNPG 推送通知需要两步: + * 在 [console.tinode.co](https://console.tinode.co) 注册并获取 TNPG 令牌。 + * 使用令牌配置服务器。 +详见[此处](../server/push/tnpg/)。 + + +### Q: 如何使用 Google FCM 设置推送通知?
+**A**: 此选项需要您构建和发布自己的移动应用。如果您不想这样做,请使用上面的 TNPG 选项。 + +启用 FCM 推送通知需要以下步骤: + * 启用服务器端推送发送。 + * 启用客户端推送接收。 + +#### 服务器和 TinodeWeb + +1. 如尚未创建,请在 https://firebase.google.com/ 创建项目。 +2. 按照 https://cloud.google.com/iam/docs/creating-managing-service-account-keys 的说明下载凭据文件。 +3. 更新服务器配置 [`tinode.conf`](../server/tinode.conf#L255),在 `"push"` -> `"name": "fcm"` 部分。执行以下**任一**操作: + * 将下载的凭据文件路径填入 `"credentials_file"`。 + * 或将文件内容复制到 `"credentials"`。

+ 删除另一个条目。例如,如果更新了 `"credentials_file"`,则删除 `"credentials"`,反之亦然。 +4. 更新 [TinodeWeb](/tinode/webapp/) 配置 [`firebase-init.js`](https://github.com/tinode/webapp/blob/master/firebase-init.js):更新 `apiKey`、`messagingSenderId`、`projectId`、`appId`、`messagingVapidKey`。详见 https://github.com/tinode/webapp/#push_notifications + +#### iOS 和 Android +1. 如果使用 Android 客户端,按照 https://developers.google.com/android/guides/google-services-plugin 的说明将 `google-services.json` 添加到 [Tindroid](/tinode/tindroid/) 并重新编译客户端。您也可以选择提交到 Google Play Store。 +详见 https://github.com/tinode/tindroid/#push_notifications +2. 如果使用 iOS 客户端,按照 https://firebase.google.com/docs/cloud-messaging/ios/client 的说明将 `GoogleService-Info.plist` 添加到 [Tinodios](/tinode/ios/) 并重新编译客户端。您也可以选择提交到 Apple AppStore。 +详见 https://github.com/tinode/ios/#push_notifications + + +### Q: 如何添加新用户?
+**A**: 创建账户有三种方式: +* 用户可以使用应用程序(Web、Android、iOS)创建新账户。 +* 可以使用 [tn-cli](../tn-cli/) 创建新账户(`acc` 命令或 `useradd` 宏)。该过程可脚本化。 +* 如果用户已存在于外部数据库,可以在首次登录时使用 [rest authenticator](../server/auth/rest/) 自动创建 Tinode 账户。 + + +### Q: 如何让我的安装私有化?
+**A**: 如果想限制只有您批准的人才能注册,最简单的方法是将 Tinode 注册限制到您控制的邮件域名:注册自定义域名,在域名注册商处设置 catch-all 邮件转发服务(通常免费)。然后在 Tinode 配置中使用您的域名(`"acc_validation" -> "email" -> "domains"`,例如 `"domains": ["my-domain.com"]`)。您会在 catch-all 邮箱收到注册邮件,然后可以手动转发验证码给您的用户。或者,如果用户很多,可以使用 [rest authenticator](../server/auth/rest/)。 + + +### Q: 如何创建 `root` 用户?
+**A**: 从 Tinode 0.18 版本开始,可以通过运行以下命令授予用户 `root` 权限: +```sh +./tinode-db -auth=ROOT -uid=usrAbcDef123 -scheme=basic +``` +从 0.21 版本开始,可以使用更简单的命令: +```sh +./tinode-db -make_root=usrAbcDef123 +``` +其中 `usrAbcDef123` 是要更新的用户 ID。 + +在 0.17 及更早版本中,只能通过执行数据库查询授予用户 `root` 权限。 +首先创建或选择要提升为 `root` 的用户,然后执行查询: +* RethinkDB: +```js +r.db('tinode').table('auth').get('basic:login-of-the-user-to-make-root').update({authLvl: 30}) +``` +* MySQL, PostgreSQL: +```sql +USE 'tinode'; +UPDATE auth SET authlvl=30 WHERE uname='basic:login-of-the-user-to-make-root'; +``` +* MongoDB: +```js +db.getCollection('auth').updateOne({_id: 'basic:login-of-the-user-to-make-root'}, {$set: {authlvl: 30}}) +``` +测试数据库有一个预设的 `xena` 用户具有 root 权限。 + + +### Q: 当网络连接数达到每节点约 1000 时,各种问题开始出现。这是 bug 吗?
+**A**: 这很可能不是 bug。为确保服务器良好性能,Linux 在内核级别限制每个进程的打开文件描述符(活动网络连接、打开文件)总数。默认限制通常是 1024。文件描述符数量还有其他可能的限制。您遇到的问题很可能是因为超过了某个 Linux 限制。请寻求系统管理员的帮助。 + + +### Q: 群组话题和频道有什么区别?
+**A**: 频道是群组话题的特例。普通群组话题允许有限数量的订阅者(默认 128)。每个订阅者可以单独管理:邀请、移除、封禁、提升为管理员或所有者,其他访问权限也可以单独调整。启用频道功能的群组话题额外允许无限数量的 `读者`。读者对话题有只读访问权限,不能单独管理,不能被邀请或移除,不能发布消息。读者加入或退出话题时不生成在线状态通知,也不接收普通群组成员的在线状态通知。读者接收的频道消息的 `From` 字段为 `null`,即他们不知道谁发布了频道中的任何特定消息。读者不能删除频道消息。 + + +### Q: 格式化 gRPC {pub content} 的正确方式是什么?
+**A**: gRPC 将 `{pub}` 消息的 `content` 字段作为字节数组发送,而客户端应用期望它是有效的 JSON。因此,在传递给 gRPC 之前,必须将字段格式化为有效的 JSON。例如,要发送纯文本 `Hello world` 消息,必须发送带引号的字符串 `"Hello world"`。大多数情况下,传递给 gRPC 调用的字符串看起来像 `"\"Hello world\""` 或 `'"Hello world"'`。 + + +### Q: 如何修复 PostgreSQL 初始化因 'missing database' 错误而失败的问题?
+**A**: PostgreSQL 有一个(不当)特性:数据库连接必须始终选择一个数据库。如果连接尝试使用不存在的数据库(即使是为了创建它),连接会失败。当 Tinode 首次启动时,它尝试创建数据库,通常是 `tinode`(见 `tinode.conf`,`"store_config": {"adapters": {"postgres": {"DBName": "tinode"}}}`。数据库 `tinode` 显然不存在,所以 Tinode 连接回退到 'default' 数据库,该数据库与连接的 PostgreSQL 用户同名。默认配置指定用户为 `postgres`(`"User": "postgres"`),数据库 `postgres` 总是存在,所以连接成功,一切正常。但如果您将用户更改为 `postgres` 以外的任何值,比如 `tinodeadmin`,麻烦就开始了:名为 `tinodeadmin` 的数据库不存在,连接失败。如果要将用户名更改为 `postgres` 以外的任何值,必须创建数据库 `tinode`(或您为 Tinode 数据库命名的任何名称)或创建一个与您的用户 `tinodeadmin` 同名的空数据库。例如: +``` +$ psql + postgres=# create database tinode; + exit +``` \ No newline at end of file diff --git a/docs/faq.md b/docs/faq.md index e69de29..946cf34 100644 --- a/docs/faq.md +++ b/docs/faq.md @@ -0,0 +1,113 @@ +# Frequently Asked Questions + +### Q: Where can I find server logs when running in Docker?
+**A**: The log is in the container at `/var/log/tinode.log`. Attach to a running container with command +``` +docker exec -it name-of-the-running-container /bin/bash +``` +Then, for instance, see the log with `tail -50 /var/log/tinode.log` + +If the container has stopped already, you can copy the log out of the container (saving it to `./tinode.log`): +``` +docker cp name-of-the-container:/var/log/tinode.log ./tinode.log +``` + +Alternatively, you can instruct the docker container to save the logs to a directory on the host by mapping a host directory to `/var/log/` in the container. Add `-v /where/to/save/logs:/var/log` to the `docker run` command. + + +### Q: What are the options for enabling push notifications?
+**A**: You can use [Tinode Push Gateway (TNPG)](https://github.com/tinode/chat/tree/master/server/push/tnpg) or you can use [Google FCM](https://firebase.google.com/docs/cloud-messaging): + * _Tinode Push Gateway_ uses Tinode servers to send pushes on your behalf. It requires minumum setup: your server sends request to TNPG, which forwards it to Google FCM or Apple APNS. + * _Google FCM_ does not rely on Tinode infrastructure for pushes but requires you to build and release your own mobile apps (iOS and Android). + + +### Q: How to setup push notifications with Tinode Push Gateway?
+**A**: Enabling TNPG push notifications requires two steps: + * register at [console.tinode.co](https://console.tinode.co) and obtain a TNPG token. + * configure server with the token. +See detailed instructions [here](../server/push/tnpg/). + + +### Q: How to setup push notifications with Google FCM?
+**A**: This option requires you to build and release your own mobile apps. If you do not want to do it, use the TNPG option above. + +Enabling FCM push notifications requires the following steps: + * enable push sending from the server. + * enable receiving pushes in the clients. + +#### Server and TinodeWeb + +1. Create a project at https://firebase.google.com/ if you have not done so already. +2. Follow instructions at https://cloud.google.com/iam/docs/creating-managing-service-account-keys to download the credentials file. +3. Update the server config [`tinode.conf`](../server/tinode.conf#L255), section `"push"` -> `"name": "fcm"`. Do _ONE_ of the following: + * _Either_ enter the path to the downloaded credentials file into `"credentials_file"`. + * _OR_ copy the file contents to `"credentials"`.

+ Remove the other entry. I.e. if you have updated `"credentials_file"`, remove `"credentials"` and vice versa. +4. Update [TinodeWeb](/tinode/webapp/) config [`firebase-init.js`](https://github.com/tinode/webapp/blob/master/firebase-init.js): update `apiKey`, `messagingSenderId`, `projectId`, `appId`, `messagingVapidKey`.

If you are using an Android client, add `google-services.json` to [Tindroid](/tinode/tindroid/) by following instructions at https://developers.google.com/android/guides/google-services-plugin and recompile the client. You may also optionally submit it to Google Play Store. +See more info at https://github.com/tinode/tindroid/#push_notifications +2.

You may optionally submit the app to Apple AppStore. +See more info at https://github.com/tinode/ios/#push_notifications + + +### Q: How to add new users?
+**A**: There are three ways to create accounts: +* A user can create a new account using one of the applications (web, Android, iOS). +* A new account can be created using [tn-cli](../tn-cli/) (`acc` command or `useradd` macro). The process can be scripted. +* If the user already exists in an external database, the Tinode account can be automatically created on the first login using the [rest authenticator](../server/auth/rest/). + + +### Q: How do I make my installation private?
+**A**: If you want to restrict registrations to only those people whom you approve, then the simplest way is to restrict Tinode registrations to an email domain you control: register a custom domain, set up a catch-all email forwarding service at your domain registrar (usually free). Then use your domain name in Tinode config (`"acc_validation" -> "email" -> "domains"`, for example `"domains": ["my-domain.com"]`). You will receive registration emails at your catch-all email box and you will be able to forward validation codes to your users manually. Alternatively, if you have a lot of users, you can use [rest authenticator](../server/auth/rest/). + + +### Q: How to create a `root` user?
+**A**: Starting with Tinode version 0.18 the `root` access can be granted to a user by running the following command: +```sh +./tinode-db -auth=ROOT -uid=usrAbcDef123 -scheme=basic +``` +Starting with 0.21 you can use a simpler command: +```sh +./tinode-db -make_root=usrAbcDef123 +``` +Where `usrAbcDef123` is the ID of the user to update. + +In version 0.17 and older the `root` access can be granted to a user only by executing a database query. +First create or choose the user you want to promote to `root` then execute the query: +* RethinkDB: +```js +r.db('tinode').table('auth').get('basic:login-of-the-user-to-make-root').update({authLvl: 30}) +``` +* MySQL, PostgreSQL: +```sql +USE 'tinode'; +UPDATE auth SET authlvl=30 WHERE uname='basic:login-of-the-user-to-make-root'; +``` +* MongoDB: +```js +db.getCollection('auth').updateOne({_id: 'basic:login-of-the-user-to-make-root'}, {$set: {authlvl: 30}}) +``` +The test database has a stock user `xena` which has root access. + + +### Q: Once the number of network connections reaches about 1000 per node, all kinds of problems start. Is this a bug?
+**A**: It is likely not a bug. To ensure good server performance Linux limits the total number of open file descriptors (live network connections, open files) for each process at the kernel level. The default limit is usually 1024. There are other possible restrictions on the number of file descriptors. The problems you are experiencing are likely caused by exceeding one of the Linux-imposed limits. Please seek assistance of a system administrator. + + +### Q: What is the difference between a group topic and a channel?
+**A**: Channel is a special case of a group topic. Normal group topics allow limited number of subscribers (128 by default). Each subscriber can be managed individually: invited, removed, banned, promoted to administrator or owner, other access permissions can be personally adjusted. Group topics with enabled channel functionality additionally permit an unlimited number of `readers`. The readers have read-only access to the topic, they cannot be managed individually, cannot be invited or removed, they cannot post messages. Readers do not generate presence notifications when joining or un-joining the topic and do not receive presence notifications from normal group members. Readers receive channel messages with `From` field set to `null`, i.e. they do not know who personally posted any given message to the channel. Readers cannot delete channel messages. + + +### Q: What is the proper way to format gRPC {pub content}?
+**A**: The gPRC sends `content` field of a `{pub}` message as a byte array while the client applications expect it to be valid JSON. Consequently, you have to format the field to be valid JSON before passing it to gRPC. For example, to send a plain text `Hello world` message you have to send a quoted string `"Hello world"`. In most cases the string you pass to the gRPC call would look like `"\"Hello world\""` or `'"Hello world"'`. + + +### Q: How to fix PostgreSQL initialization failing with 'missing database' error?
+**A**: PostgreSQL has a (mis)feature: a DB connection must always select a database. If the connection tries to use a database which does not exist (even with intent to create it), the connection fails. When Tinode is started for the first time, it tries to create a database, usually `tinode` (see `tinode.conf`, `"store_config": {"adapters": {"postgres": {"DBName": "tinode"}}}`. The database `tinode` obviously does not exist, so Tinode connection falls back to 'default' database which has the same name as the name of the connecting PostgreSQL user. The default configuration specifies user as `postgres` (`"User": "postgres"`), the database `postgres` always exists, so the connection succeeds and everything works as expected. But if you change the user to anything other than `postgres`, let's say `tinodeadmin`, then trouble starts: the database with the name `tinodeadmin` does not exist and the connection fails. If you want to change the user name to anything other than `postgres`, then you must create either a database `tinode` (or whatever you named your Tinode database) or an empty database with the same name as your user `tinodeadmin`. For example: +``` +$ psql + postgres=# create database tinode; + exit +``` diff --git a/docs/images/@人员—完成.png b/docs/images/@人员—完成.png new file mode 100644 index 0000000..ff0cf07 Binary files

Try it as +``` +python tn-cli.py < sample-script.txt +``` + +### Local (non-networking) + +* `.await` - issue a gRPC call and wait for completion, optionally assign result to a variable. +* `.delmark` - use custom delete marker instead of default `DEL!`; needed when some value is to be removed rather than set to blank. +* `.exit` - terminate execution and exit the CLI; also `.quit`. +* `.log` - write a value of a variable to `stdout`. +* `.must` - issue a gRPC call and wait for completion, optionally assign result to a variable; raise an exception if result is not a success. +* `.quit` - terminate execution and exit the CLI; also `.exit`. +* `.sleep` - suspend the process for a number of milliseconds. +* `.use` - set default user (on_behalf_of user) or topic. +* `.verbose` - toggle logging verbosity. + +### gRPC calls + +* `acc` - create or modify an account +* `login` - authenticate current session +* `sub` - subscribe to topic +* `leave` - detach or unsubscribe from topic +* `pub` - post message to topic +* `get` - query topic for metadata or messages +* `set` - update topic metadata +* `del` - delete message(s), topic, subscription, or user +* `note` - send notification +* `file` - upload or download large file out of band + +### HTTP requests + +* `upload` - (deprecated, use `file`) upload file out of band + +### Macros + +Macros are high-level wrappers for series of gRPC calls. Currently, the following macros are [available](macros.py): + +* `chacs` - change default permissions/acs for a user (requires root privileges) +* `chcred` - add or delete a credential for a user (requires root privileges) +* `passwd` - set user's password (requires root privileges) +* `resolve` - resolve login and print the corresponding user id +* `useradd` - create a new user account +* `userdel` - delete user account (requires root privileges) +* `usermod` - modify user account (requires root privileges) +* `thecard` - print user's public and private info (requires root privileges) + +You can define your own macros in [macros.py](macros.py) or create a separate python module (you can load it via `--load-macros`). +Refer to [macros.py](macros.py) for examples. + +## Connecting to secure (HTTPS) server + +If the server is configured to use TLS, i.e. running as `httpS://my-server.example.com/`, the gRPC endpoint also uses the same SSL certificate. In that case add the `--ssl` option. + +If you want to connect to the secure gRPC endpoint over a local network or under a different name i.e. as `localhost` instead of `my-server.example.com` in this example, you must specify the SSL domain name to use, otherwise the server will not be able to find the right SSL certificate: +``` +python tn-cli.py --host=localhost:6001 --ssl --ssl-host=my-server.example.com +``` +The `--ssl-host` option makes the connection susceptible to the [Man-in-the-middle attack](https://en.wikipedia.org/wiki/Man-in-the-middle_attack), so don't do it over public networks. + +## Crash on shutdown + +Python 3.6 sometimes crashes on shutdown with a message `Fatal Python error: PyImport_GetModuleDict: no module dictionary!`.
