+# Hermes Feishu Bridge
+
+双向桥接服务：
+
+- `POST /feishu/events`：飞书事件回调。收到文本消息后后台调用 Hermes，再发回飞书。
+- `POST /feishu/notify`：Hermes 或内部系统主动通知飞书。必须带 `Authorization: Bearer $FEISHU_NOTIFY_TOKEN` 或 `X-Hermes-Feishu-Token`。
+- `GET /health`：健康检查。
+
+## 凭证
+
+不要把 `FEISHU_APP_SECRET`、`HERMES_API_KEY`、`FEISHU_NOTIFY_TOKEN` 写入仓库。线上使用 `/etc/hermes-feishu-bridge.env` 或同等级别的部署密钥文件。
+
+## 飞书后台配置
+
+1. 给自建应用开通消息相关权限，例如接收消息事件、获取与发送单聊/群组消息。
+2. 事件订阅里添加请求地址：`https://hermes.kang-kang.com/feishu/events`。
+3. 如果启用事件加密，需要先给本服务补充解密支持；当前版本按明文事件回调处理。
+4. 建议配置 `FEISHU_VERIFICATION_TOKEN`，并保持和飞书后台一致。
+
+## 主动通知示例
+
+```bash
+curl -X POST https://hermes.kang-kang.com/feishu/notify \
+  -H "Authorization: Bearer $FEISHU_NOTIFY_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"receive_id_type":"chat_id","receive_id":"oc_xxx","text":"任务完成"}'
