From b0801e0983249d9eb4601cf46a512b0b305cecf9 Mon Sep 17 00:00:00 2001 From: hailin Date: Sun, 8 Mar 2026 05:10:01 -0700 Subject: [PATCH] feat(bridge): DingTalk channel plugin + OpenClaw Protocol v3 rewrite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Core changes: - src/channels/dingtalk.ts: DingTalk Stream SDK channel (no public IP needed) - TokenManager: auto-refresh with refreshPromise mutex (prevents race condition) - UserQueue: per-user serial queue, max depth 5 - MsgDedup: O(1) Map with 10min TTL + 10k cap - RateLimiter: sliding window 10 msg/min per user - ResilientOcClient: 10s heartbeat poll + atomic reconnect guard - DingTalkStream: exponential backoff reconnect (2s→60s), immediate ACK - replyToUser: sessionWebhook expiry check + 4800-char chunking - src/openclaw-client.ts: rewritten for correct Protocol v3 wire format - Request frame: { type:"req", id, method, params } - Challenge-response Ed25519 handshake (connect.challenge → connect req) - Correct rpc() with configurable timeoutMs - src/index.ts: fixed RPC method names - agent.run → chat.send with { sessionKey, message, timeoutSeconds } - metrics.get → gateway.status - Dockerfile: adds start-dingtalk.sh COPY + chmod - supervisord.conf: dingtalk-channel program block (autorestart=unexpected) - start-dingtalk.sh: exits 0 if DINGTALK_CLIENT_ID unset (no restart loop) - CHANNEL_DEV_GUIDE.md: full dev guide for future channel integrations Co-Authored-By: Claude Sonnet 4.6 --- packages/openclaw-bridge/CHANNEL_DEV_GUIDE.md | 471 +++++++ packages/openclaw-bridge/Dockerfile | 4 + packages/openclaw-bridge/package-lock.json | 1207 +++++++++++++++++ packages/openclaw-bridge/package.json | 1 + .../openclaw-bridge/src/channels/dingtalk.ts | 547 ++++++++ packages/openclaw-bridge/src/index.ts | 19 +- .../openclaw-bridge/src/openclaw-client.ts | 194 ++- packages/openclaw-bridge/start-dingtalk.sh | 8 + 8 files changed, 2399 insertions(+), 52 deletions(-) create mode 100644 packages/openclaw-bridge/CHANNEL_DEV_GUIDE.md create mode 100644 packages/openclaw-bridge/package-lock.json create mode 100644 packages/openclaw-bridge/src/channels/dingtalk.ts create mode 100644 packages/openclaw-bridge/start-dingtalk.sh diff --git a/packages/openclaw-bridge/CHANNEL_DEV_GUIDE.md b/packages/openclaw-bridge/CHANNEL_DEV_GUIDE.md new file mode 100644 index 0000000..949b8f6 --- /dev/null +++ b/packages/openclaw-bridge/CHANNEL_DEV_GUIDE.md @@ -0,0 +1,471 @@ +# OpenClaw Channel 插件开发指南 + +> 基于钉钉 Channel 插件（`src/channels/dingtalk.ts`）的完整开发经验总结。 +> 开发新 Channel 时，本文档是你的第一参考。 + +--- + +## 一、整体架构 + +每个 OpenClaw 实例是一个独立 Docker 容器（`hailin168/openclaw-bridge:latest`）。 +容器内有三个进程，由 supervisord 管理： + +``` +容器 +├── openclaw gateway 端口 18789 (内部) — 核心 AI Agent 进程 +├── it0-bridge 端口 3000 (对外) — IT0 管理 REST API +└── dingtalk-channel 无对外端口 — 第三方 Channel 进程（可选） +``` + +**Channel 插件的职责：** +1. 连接第三方平台（接收用户消息） +2. 转发给 OpenClaw Gateway（通过 WebSocket RPC） +3. 将 OpenClaw 响应回发给用户 + +Channel 插件不需要任何对外端口，完全依赖出向连接。 + +--- + +## 二、OpenClaw Gateway 协议 (Protocol v3) + +> ⚠️ 这是最重要的部分。协议细节必须准确，否则运行时全部失败，TypeScript 编译器无法检测。 + +### 2.1 Wire 帧格式 + +```typescript +// 请求帧（Client → Gateway） +interface ReqFrame { + type: 'req';

Discord — 开发者/社区场景 + +--- + +## 八、经验教训（避坑清单） + +1. **永远先读官方源码，不要猜 API 方法名** + - 本项目曾把 `chat.send` 猜成 `agent.run`，`gateway.status` 猜成 `metrics.get`，TypeScript 编译通过但 runtime 全部失败 + - 查源码路径：github.com/openclaw/openclaw 的 `src/gateway/server-methods/` + +2. **Channel token 必须有自动续期机制** + - 钉钉 Access Token 2小时过期，不续期则服务必然中断 + - 在 `get()` 中加 Promise 互斥锁，防止并发双重刷新 + +3. **永远在收到消息后立即 ACK，再异步处理 AI** + - 钉钉 ACK 超时 1.5 秒，AI 响应可能需要 30 秒 + - 先 `ws.send(ACK)`，再 `queue.enqueue()` 异步处理 + +4. **消息去重用 Map，不用 Array** + - `Array.includes()` 是 O(n)，5000条消息时每次查找慢 5ms + - `Map.get()` 是 O(1)，加 TTL 可精确控制内存 + +5. **supervisord 的 autorestart 要用 unexpected，不是 true** + - `autorestart=true` + 未配置时 exit 0 → 无限重启循环 + - `autorestart=unexpected` + `exitcodes=0` → 正常退出不重启 + +6. **每用户消息队列必须有深度上限** + - 用户刷消息时，无限队列会耗尽内存 + - 建议上限 5 条，超出告知用户"请等待" + +7. **OpenClaw 重连不要用嵌套 setInterval + async** + - 多个 interval tick 可能同时触发多个重连 goroutine + - 用 flag 原子保护 + 单一递归 `attempt()` 函数 + +8. **回复消息要检查 webhook 过期时间** + - 某些平台的 webhook 有效期很短（几分钟到几小时） + - AI 处理完后要先检查 `webhookExpiredTime`，过期则不发 + +9. **容器内没有 curl，用 wget 或 Node.js https 模块** + - `hailin168/openclaw-bridge` 镜像内无 curl + - `wget -q -O- --post-data=...` 是
