即使服务正常运行，也无法使用基于云的windows服务从生物识别设备中获取员工的考勤数据

这是窗口服务代码的一小部分，用于从云端获取生物识别设备的实时考勤数据。该服务从设备中获取数据，并存储在项目文件夹中，形成.log文件，但当在设备上打卡时，我什么都没有得到。请帮助我。我对这个WebSocketServer完全陌生。

private void webSocketServer_NewMessageReceived(WebSocketSession session, string message) 这个方法是用来注册新设备的，但是当我把卡打到设备上时，这个方法没有启动。我没有在这个方法中粘贴所有代码。

 using SuperWebSocket;
 using SuperSocket.SocketBase;        
 public class WebSocketLoader
        private static WebSocketServer webSocketServer;
        public static Dictionary<string, string> _registeredDevices;
        private WebSocketLoader(IWorkItem server)
            var wsServer = server as WebSocketServer;
            webSocketServer = wsServer;
        public static WebSocketSession GetSessionByID(string sn)
            if (_registeredDevices.ContainsKey(sn))
                return  webSocketServer.GetAppSessionByID(_registeredDevices[sn]);
                return null;
        public static void Setup(IWorkItem server)
            var webSocketLoader = new WebSocketLoader(server);
            webSocketLoader.AddNewMessageReceived();
            webSocketLoader.AddNewSessionConnected();
            webSocketLoader.AddSessionClosed();
            _registeredDevices = new Dictionary<string, string>();
            _registeredDevices.Clear();
        public void AddNewMessageReceived()
            webSocketServer.NewMessageReceived += new SessionHandler<WebSocketSession, string>(webSocketServer_NewMessageReceived);
        public void AddNewSessionConnected()
            webSocketServer.NewSessionConnected += new SessionHandler<WebSocketSession>(webSocketServer_NewSessionConnected);
        private void webSocketServer_NewSessionConnected(WebSocketSession session)
            Console.WriteLine(webSocketServer.GetAllSessions().Count());
            LogHelper.Receive("NewConnected[" + session.RemoteEndPoint + "]");
        private void webSocketServer_SessionClosed(WebSocketSession session, CloseReason reason)
            LogHelper.Receive("Closed[" + session.RemoteEndPoint + "],Reason:" + reason);
        private void webSocketServer_NewMessageReceived(WebSocketSession session, string message)
            Console.WriteLine(webSocketServer.GetAllSessions().Count());
            LogHelper.Receive("MessageReceived[" + session.RemoteEndPoint + "],Message:" + message);
App.config文件包含以下一行
