## 📊 数据流设计
|
|||
|
|
|
|||
|
|
### 用户消息流程
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. 用户 → WebSocket 连接 → 智队中枢
|
|||
|
|
2. 智队中枢 → 验证 JWT Token
|
|||
|
|
3. 智队中枢 → SessionService 创建/获取会话
|
|||
|
|
4. 智队中枢 → AgentScheduler 选择最优 Agent
|
|||
|
|
5. 智队中枢 → WebSocket 转发消息给 Agent
|
|||
|
|
6. Agent 处理 → 返回响应
|
|||
|
|
7. 智队中枢 → 消息持久化 (PostgreSQL)
|
|||
|
|
8. 智队中枢 → WebSocket 返回给用户
|
|||
|
|
9. 用户 → 消息确认 (ACK)
|
|||
|
|
10. 智队中枢 → 更新消息状态
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Agent 注册流程
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. Gateway → POST /api/gateways 注册 Gateway
|
|||
|
|
2. Gateway → POST /api/agents/:id/heartbeat 心跳
|
|||
|
|
3. 智队中枢 → AgentService 更新状态
|
|||
|
|
4. 智队中枢 → Scheduler 添加到候选列表
|
|||
|
|
5. 用户请求 → Scheduler 选择 Agent
|
|||
|
|
6. 智队中枢 → WebSocket 分配会话
|
|||
|
|
```

## 🚀 下一步计划
|
|||
|
|
|
|||
|
|
1. **集成测试** - 完善 WebSocket 流程测试
|
|||
|
|
2. **部署测试** - Docker Compose 本地部署验证
|
|||
|
|
3. **Nginx 配置** - 添加 HTTPS + WSS 反向代理
|
|||
|
|
