sync.WaitGroup wg.Add(3) // 调用第三方摄像 sdk go func() { err = CameraInit(outsideIp, mysql) if err != nil { for { err = CameraInit(outsideIp, mysql) if err != nil { time.Sleep(time.Duration(5) * time.Second) continue } break } } }() // xxx 设备 socket 通信 go xxxSocketInit( ) // yyy 设备 socket 通信 go yyySocketInit(mysql) wg.Wait() ``` 下面两个 socket 都没有用 sync, 第一个调用第三方的摄像sdk，只有调用功能，不清楚问题出在哪里
