3个并行智能体开发 + 审计智能体审查: B1.1 ClassSerializerInterceptor: - AppSerializerInterceptor 深度递归序列化 - @ExposeGroups() 分组控制字段暴露 - SysUser/Member password @Exclude() - Member openid @Expose(groups:['owner']) B1.2 自研限流增强: - @Throttle() 装饰器支持路由级差异化配置 - X-RateLimit-Limit/Remaining/Reset 标准响应头 - skipIf 回调支持条件跳过 - 内存泄漏修复(60s定期清理) - IP解析修复(取x-forwarded-for首个IP) - 真正滑动窗口(时间戳队列) B1.3 WebSocket Gateway: - @WebSocketGateway /notifications 命名空间 - JWT认证握手 + userId→socketId映射 - WsNotificationEmitter 事件推送 - WsPushNotificationListener 事件桥接 安全加固(审计S7): - CORS收紧(环境变量WS_ALLOWED_ORIGINS) - WebSocket IP连接限流(MAX=10) - Token仅通过auth传递(移除query) - Member.idCard/MemberCashOutAccount.accountNo/Verify.code @Exclude() Docker: - 多阶段Dockerfile(deps→builder→runner) - docker-compose.yml(app+mysql+redis+kafka+zk) - E2E测试脚本 + 压力测试脚本(autocannon) 质量: tsc 0 error / eslint 0 error / any 0 / build ok
