+# WPS365 Channel Plugin
+
+Clawdbot 的 WPS365 开放平台频道插件，支持通过 WPS 协作机器人接收和发送消息。
+
+## 前置要求
+
+1. 在 [WPS 开发者后台](https://open.wps.cn/developer/home) 创建应用
+2. 获取以下凭证：
+   - **App ID** (client_id)
+   - **App Secret** (client_secret)
+   - **Company ID** (企业 ID)
+3. 配置应用权限：`kso.chat_message.readwrite`（查询和管理会话消息）
+4. 配置事件订阅（如需接收消息）
+
+## 安装
+
+```bash
+# 通过 npm 安装
+clawdbot extensions install @clawdbot/wps
+
+# 或从本地安装（开发时）
+clawdbot extensions install ./extensions/wps
+```
+
+## 配置
+
+在 `~/.clawdbot/config.json` 中添加以下配置：
+
+```json
+{
+  "channels": {
+    "wps": {
+      "enabled": true,
+      "appId": "your-app-id",
+      "appSecret": "your-app-secret",
+      "companyId": "your-company-id",
+      "baseUrl": "https://openapi.wps.cn",
+      "webhook": {
+        "path": "/wps/webhook",
+        "port": 3000
+      },
+      "dmPolicy": "pairing",
+      "allowFrom": [],
+      "groupPolicy": "allowlist",
+      "groups": {}
+    }
+  }
+}
+```
+
+### 配置项说明
+
+| 配置项 | 类型 | 必填 | 默认值 | 说明 |
+|--------|------|------|--------|------|
+| `enabled` | boolean | 否 | `true` | 是否启用 WPS 频道 |
+| `appId` | string | 是 | - | WPS 应用 ID (client_id) |
+| `appSecret` | string | 是 | - | WPS 应用密钥 (client_secret) |
+| `companyId` | string | 是 | - | WPS 企业 ID |
+| `baseUrl` | string | 否 | `https://openapi.wps.cn` | WPS API 基础 URL |
+| `enableEncryption` | boolean | 否 | `true` | 是否启用事件加密解密 |
+| `webhook.path` | string | 否 | `/wps/webhook` | Webhook 接收路径 |
+| `webhook.port` | number | 否 | `3000` | Webhook 监听端口 |
+| `dmPolicy` | string | 否 | `pairing` | 私聊策略：`open`/`allowlist`/`pairing` |
+| `allowFrom` | string[] | 否 | `[]` | 允许的用户 ID 列表 |
+| `groupPolicy` | string | 否 | `allowlist` | 群聊策略：`open`/`allowlist` |
+| `groups` | object | 否 | `{}` | 群聊配置 |
+
+### DM 策略说明
+
+- **`open`**：接受所有人的消息（不推荐）
+- **`allowlist`**：仅接受 `allowFrom` 列表中用户的消息
+- **`pairing`**：新用户需要通过配对码验证（推荐）
+
+## 事件加密
+
+WPS 事件订阅默认启用加密。收到的事件会经过以下处理：
+
+1. **签名验证**: 使用 `HMAC-SHA256(appSecret, "appId:topic:nonce:time:encrypted_data")` 验证签名
+2. **数据解密**: 使用 `AES-128-CBC` 解密，密钥为 `MD5(appSecret)`，IV 为 `nonce`
+
+如果需要禁用加密验证（仅用于调试），设置 `enableEncryption: false`。
+
+## 配置事件订阅
+
+要接收用户消息，需要在 WPS 开发者后台配置事件订阅：
+
+1. 进入应用管理 → 事件订阅
+2. 配置回调地址：`https://your-domain.com/wps/webhook`
+3. 订阅消息接收事件
+
+### Webhook URL 格式
+
+```
+https://<your-domain>:<port><path>
+```
+
+示例：`https://bot.example.com:3000/wps/webhook`
+
+## 运行
+
+启动 Clawdbot Gateway 后，WPS 频道会自动启动：
+
+```bash
+clawdbot gateway run
+```
+
+检查频道状态：
+
+```bash
+clawdbot channels status
+```
+
+## 发送消息
+
+通过 CLI 发送消息：
+
+```bash
+# 发送到会话
+clawdbot message send --channel wps --target <chat_id> --message "Hello!"
+
+# 发送到用户（需要用户 ID）
+clawdbot message send --channel wps -t <user_id> -m "Hello!"
+```
+
+## API 参考
+
+### 消息发送
+
+- **单条消息**：`POST /v7/messages/create`
+- **批量消息**：`POST /v7/messages/batch_create`
+
+详细文档：
+- [发送消息](https://open.wps.cn/documents/app-integration-dev/wps365/server/im/message/single-create-msg)
+- [事件订阅](https://open.wps.cn/documents/app-integration-dev/wps365/server/im/event/receive-msg)
+
+## 故障排除
+
+### 凭证未配置
+
+```
+WPS credentials not configured (appId, appSecret, and companyId required)
+```
+
+确保在配置文件中正确设置了 `appId`、`appSecret` 和 `companyId`。
+
+### Token 获取失败
+
+```
+Failed to get WPS access token: 401
+```
+
+检查 `appId` 和 `appSecret` 是否正确，以及应用是否已授权给目标企业。
+
+### 消息发送失败
+
+```
+WPS send error (code xxx): ...
+```
+
+常见错误码：
+- `403`：权限不足，检查应用权限配置
+- `404`：目标用户或会话不存在
+- `429`：请求频率超限
+
+## 开发
+
+```bash
+# 安装依赖
+cd extensions/wps
+pnpm install
+
+# 类型检查
+pnpm build
+
+# 在主项目中测试
+cd ../..
+pnpm clawdbot channels status
+```
