1 | # EaseChat 2 | 3 | Simple message exchange network with channel-subscription based structure. 4 | EaseChat was originally designed as a chat message exchanging service for games, but its usage could be widen to debug messages 5 | and commands for maintaining. 6 | 7 | Although the first version of EaseChat Nexus may be less flexible, we deployed it on production use months ago. 8 | Its record on non-pausing and reboot-free continous execution is 3,432 hours on our mini-game server network region, since 30 Jan to 22 Jun 2019, killed mistaken by a ctrl-c quit. The network consists of ~350 endpoints and produces ~1k messages on average per second, their CPU and RAM usage being low at the same time. 9 | Players mostly suggest it 'Great' in our recent survey on this part of the game's experience. 10 | 11 | ## Project structure 12 | 13 | | Name | Description | 14 | |:----|:-----------| 15 | | easechat-client-j | Netty-based Java implementation of EaseChat client oriented to production | 16 | | easechat-exec-rs | (In progress) Complete cli application of EaseChat in Rust | 17 | | easechat-nexus-rs | First version of Rust EaseChat nexus impl using mio and ws | 18 | | easechat-nexus-v2-rs | (In progress) Redesigned Rust EaseChat protocol library intended for general use | 19 | | easechat-record-rs | (In progress) Simple Rust cli EaseChat client app, connect to nexus and save message via SQLite | 20 | 21 | ## Run EaseChat Nexus 22 | 23 | 1. Install [rust](https://rust-lang.org/), or run `rustup update` if already installed. 24 | 2. Execute `cargo run -p ease_chat_nexus` in project root. 25 | 26 | Step 1 is necessary because this EaseChat Nexus implementation requires rust edition 2018 installed. 27 | This implementation is written in rust version 1.32.0-stable. 28 | 29 | ## Protocol specification 30 | 31 | [中文协议文档](https://github.com/EaseCation/ease_chat/blob/master/protocol-zh.md) 32 | -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 4.0.0 6 | 7 | net.easecation 8 | easechat 9 | 1.0-SNAPSHOT 10 | pom 11 | 12 | 13 | src/easechat-client-j 14 | 15 | 16 | -------------------------------------------------------------------------------- /protocol-zh.md: -------------------------------------------------------------------------------- 1 | # Protocol 协议说明 2 | 3 | ### 基本： 4 | 5 | - 本协议暂时基于WebSocket，属于内网协议 6 | - 为方便调试，直接通过传递字符串进行信息交换，在字符串中使用`|`分割信息体 7 | - 未来将使用可靠性可选的、基于UDP的虚拟连接协议，以字节方式传输；加强安全性，以便开放到公网 8 | 9 | ### 协议种类： 10 | 11 | pid位于数据的第一部分。一般由一个数字与一个简写字母组成。数字代表协议版本号，后方字母代表协议分类。 12 | 13 | Client发送给Nexus的有以下类型： 14 | 15 | - `1h` Hello 握手 16 | - `1c` Channel 订阅频道 17 | - `1t` Transmit 发送消息 18 | - `1d` Disconnect 断开连接 19 | 20 | Nexus主动发送给Client的有以下类型： 21 | 22 | - `1r` Receive 接收消息 23 | 24 | ## 协议内容： 25 | 26 | `Tip：为了防止注入，涉及到第三方可编辑的字符串部分，都特别加入了字符串长度用于检验。` 27 | 28 | ### `1h` Hello 握手： 29 | 30 | 组合方式：1h|名称`长度(字节)`|名称 31 | 32 | _握手是为了上报服务端，该客户端的`名称`，用于发送消息时告知其他客户端消息的来源。_ 33 | 34 | 例如：`1h|12|abcdef123456` 35 | 36 | ### `1c` Channel 订阅频道： 37 | 38 | 组合方式：1c|频道名字`长度(字节)`|频道名字|需要订阅的时间(秒部分)|需要订阅的时间(纳秒部分) 39 | 40 | _订阅就像续命，客户端需要定时订阅频道，来告知服务端需要向我发送哪些频道的消息。_ 41 | 42 | 例如： 43 | 订阅c/lobby频道五分钟 `1c|7|c/lobby|300|0` 44 | 45 | ### `1t` Transmit 发送消息： 46 | 47 | 组合方式：1t|频道`长度(字节)`|频道名字|消息`长度(字节)`|消息 48 | 49 | _客户端发送给服务端_ 50 | 51 | 例如： 52 | 发送helloworld到c/lobby频道 `1t|7|c/lobby|10|helloworld` 53 | 54 | ### `1d` Disconnect 断开连接： 55 | 56 | 组合方式：1d|理由`长度(字节)`|理由 57 | 58 | _发送后，应由服务端断开连接_ 59 | 60 | 例如：`1d|11|just logout` 61 | 62 | ### `1r` Receive 接收消息： 63 | 64 | 组合方式：1r|消息来源字符串`长度(字节)`|消息来源|频道字符串`长度(字节)`|频道|消息字符串`长度(字节)`|消息 65 | 66 | _客户端订阅后，由中转枢纽主动发送给客户端。中转枢纽将忽略所有客户端发来的1r类型消息。_ 67 | -------------------------------------------------------------------------------- /src/easechat-client-j/build.gradle.kts: -------------------------------------------------------------------------------- 1 | plugins { 2 | application 3 | id("ecbuild.java-conventions") 4 | } 5 | 6 | application { 7 | mainClass = "net.easecation.easechat.Main" 8 | } 9 | 10 | dependencies { 11 | api(libs.netty.all) 12 | } 13 | 14 | description = "easechat-client-j" 15 | -------------------------------------------------------------------------------- /src/easechat-client-j/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 4.0.0 6 | 7 | net.easecation 8 | easechat-client-j 9 | 1.0-SNAPSHOT 10 | 11 | 12 | 21 13 | 21 14 | UTF-8 15 | 16 | 17 | 18 | 19 | io.netty 20 | netty-all 21 | 4.1.107.Final 22 | 23 | 24 | 25 | 26 | ${project.artifactId} 27 | 28 | 29 | org.apache.maven.plugins 30 | maven-shade-plugin 31 | 3.6.0 32 | 33 | 34 | package 35 | 36 | shade 37 | 38 | 39 | 40 | 41 | net.easecation.easechat.Main 42 | 43 | 44 | ${project.build.directory}/dependency-reduced-pom.xml 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | -------------------------------------------------------------------------------- /src/easechat-client-j/src/main/java/net/easecation/easechat/Main.java: -------------------------------------------------------------------------------- 1 | package net.easecation.easechat;
