 # gc-opencommand-plugin
 
+中文 | [English](README_en-US.md)
+
 一个为第三方客户端开放GC命令执行接口的插件
 
-# 服务端安装
+自 `1.7.0` 起可以通过 `|` 或者换行来分隔多条命令，例如：
+```shell
+/a 1 | /a 2
+/a 3
+```
+
+调用 `ping` 响应数据将包含插件版本号。
+
+## 使用本插件的应用
+- [GrasscutterTools](https://github.com/jie65535/GrasscutterCommandGenerator) —— Windows 客户端工具
+- [JGrasscutterCommand](https://github.com/jie65535/JGrasscutterCommand) —— [Mirai](https://github.com/mamoe/mirai) 插件，在QQ里执行命令
+- [Yunzai-GrasscutterCommand](https://github.com/Zyy-boop/Yunzai-GrasscutterCommand) —— Yunzai-bot插件，在QQ里执行命令
+- 待补充
+
+## 服务端安装
+
 1. 在 [Release](https://github.com/jie65535/gc-opencommand-plugin/releases) 下载 `jar`
-2. 放入 `plugins` 文件夹即可
+2. 放入 `grasscutter/plugins` 文件夹
+3. 重启 `grasscutter` 即可生效
 
-# 构建说明
+## 玩家使用流程
-1. 克隆仓库
-2. 在目录下新建 `lib` 目录
-3. 将 `grasscutter-1.1.x-dev.jar` 放入 `lib` 目录
-4. `gradle build`
 
-# 玩家使用流程
+1. 在远程工具中填写服务地址，查询插件状态
-1. 在客户端中填写服务地址，确认是否支持
+2. 填写UID，发送验证码（需要在线）
-2. 填写UID，发送验证码
+3. 将游戏内收到的**4位整数验证码**填入工具校验
-3. 将游戏内收到的**4位整数验证码**填入客户端校验
 4. 享受便利！
 
-# 客户端请求流程
+## 控制台连接
+
+1. 首次启动时，会在 `plugins` 目录下生成一个 `opencommand-plugin` 目录，打开并编辑 `config.json`
+2. 设置 `consoleToken` 的值为你的连接秘钥，建议使用至少32字符的长随机字符串。（检测到为空时会自动生成，生成时会在控制台中输出）
+3. 重新启动服务端即可生效配置
+4. 在工具中选择控制台身份，并填写你的 `consoleToken` 即可以控制台身份运行指令
+
+---
+
+## 客户端请求流程
+
 1. `ping` 确认是否支持 `opencommand` 插件
 2. `sendCode` 向指定玩家发送验证码（1分钟内不允许重发），保存返回的 `token`
 3. 使用 `token` 和**4位整数验证码**发送 `verify` 校验
 4. 如果验证通过，可以使用该 `token` 执行 `command` 动作
 
+## 插件构建说明
+
+1. 克隆仓库
+2. 在目录下新建 `lib` 目录
+3. 将 `grasscutter.jar` 放入 `lib` 目录
+4. 执行 `gradle build`
+
+## 多服务器
+### 主服务器 (Dispatch)
+1. 在 `opencommand-plugin` 目录下打开 `config.json`
+2. 修改 `socketPort` 值为一个未被使用的端口
+3. 设置 `socketToken` 多服务器通信密钥，建议使用至少32字符的长随机字符串。
+4. 重新启动服务端即可生效配置
+
+### 子服务器 (Game)
+1. 在 `opencommand-plugin` 目录下打开 `config.json`
+2. 修改 `socketHost` 和 `socketPort` 值为主服务器的地址和端口
+3. 设置 `socketToken` 和主服务器相同的值
+4. 设置 `socketDisplayName` 值为你的服务器名称 (用途请见[下方](https://github.com/jie65535/gc-opencommand-plugin#%E8%8E%B7%E5%8F%96%E5%A4%9A%E6%9C%8D%E5%8A%A1%E5%99%A8%E5%88%97%E8%A1%A8))
+5. 重新启动服务端即可生效配置

+# gc-opencommand-plugin
+
+[中文](README.md) | English
+
+A plugin that opens the GC command execution interface for third-party clients
+
+Since `1.7.0`, multiple commands can be separated by `|` or newline, for example:
+```shell
+/a 1 | /a 2
+/a 3
+```
+
+Invoking `ping` the response data will contain the plugin version.
+
+## Applications using this plug-in
+- [GrasscutterTools](https://github.com/jie65535/GrasscutterCommandGenerator) —— Windows Client Tools
+- [JGrasscutterCommand](https://github.com/jie65535/JGrasscutterCommand) —— [Mirai](https://github.com/mamoe/mirai) Plugin, run commands in QQ
+- [Yunzai-GrasscutterCommand](https://github.com/Zyy-boop/Yunzai-GrasscutterCommand) —— Yunzai-bot plugin, execute commands in QQ
+- More...
+
+## Server installation
+
+1. Download the `jar` in [Release](https://github.com/jie65535/gc-opencommand-plugin/releases)
+2. Put it in the `grasscutter/plugins` folder
+3. Restart `grasscutter` server
+
+## Player
+
+1. Fill in the service address in the Tool to check plugin status
+2. Fill in the UID and send the verification code
+3. Fill in the **4-digit integer verification code** received in the game into the Tool verification
+4. Enjoy the convenience!
+
+## Console connection
+
+1. When starting for the first time, a `opencommand-plugin` directory will be generated under the `plugins` directory,
+   open and edit `config.json`
+2. Set the value of `consoleToken` to your connection key. It is recommended to use a long random string of at least 32
+   characters. (automatically generated when empty is detected)
+3. Restart the server to take effect
+4. Select the console identity in the client, and fill in your `consoleToken` to run the command as the console identity
+
+---
+
+## Client request
+
+1. `ping` to confirm whether the `opencommand` plugin is supported
+2. `sendCode` sends a verification code to the specified player (re-send is not allowed within 1 minute), and save the
+   returned `token`
+3. Send `verify` check using `token` and **4-digit integer verification code**
+4. If the verification is passed, you can use the `token` to execute the `command` action
+
+## Build
+
+1. `git clone https://github.com/jie65535/gc-opencommand-plugin`
+2. `cd gc-opencommand-plugin`
+3. `mkdir lib`
+4. `mv path/to/grasscutter-1.x.x-dev.jar ./lib`
+5. `gradle build`
+
+## Multi server
+### Master server (Dispatch)
+1. Open `config.json` in the `opencommand-plugin` directory
+2. Modify the `socketPort` value to an unused port
+3. Set `sockettoken` multi server communication key. It is recommended to use a long random string of at least 32 characters.
+4. Restart the server to make the configuration effective
+
+### Sub server (Game)
+1. Open `config.json` in the `opencommand-plugin` directory
+2. Modify the `sockethost` and `socketport` values to the address and port of the primary server
+3. Set the same value of `sockettoken` and the primary server
+4. Set the `socketDisplayName` value to your server name (See below for usage [Jump](https://github.com/jie65535/gc-opencommand-plugin/blob/master/README_en-US.md#get-mulit-server-list))
+5. Restart the server to make the configuration effective
+
+---
+
+## `config.json`
+
+```json5
+{
+   // console connection token (automatically generated when empty is detected)
+  "consoleToken": "",
+   // Verification code expiration time (seconds)
+  "codeExpirationTime_S": 60,
+   // Temporary token expiration time (seconds)
+  "tempTokenExpirationTime_S": 300,
+  // Authorization token last used expiration time (hours)
+  "tokenLastUseExpirationTime_H": 48,
+   // Multi-server communication port
+   "socketPort": 5746,
+   // Multi-server communication key
+   "socketToken": "",
+   // Multi-server Dispatch server address
+   "socketHost": "127.0.0.1",
