action代码

         public HttpResponseMessage T()        {            if (System.Web.HttpContext.Current.IsWebSocketRequest)            {                System.Web.HttpContext.Current.AcceptWebSocketRequest(ProcessWSChat);            }            return new HttpResponseMessage(HttpStatusCode.SwitchingProtocols);            //return View();        }        private async Task ProcessWSChat(AspNetWebSocketContext context)        {            System.Net.WebSockets.WebSocket socket = context.WebSocket;            while (true)            {                //ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[1024]);                //WebSocketReceiveResult result = await socket.ReceiveAsync(                //    buffer CancellationToken.None);                if (socket.State == WebSocketState.Open)                {                    //string userMessage = Encoding.UTF8.GetString(                    //    buffer.Array 0 result.Count);                    string userMessage = DateTime.Now.ToString();                    ArraySegment<byte> buffer = new ArraySegment<byte>(                        Encoding.UTF8.GetBytes(userMessage));                    await socket.SendAsync(                        buffer WebSocketMessageType.Text true CancellationToken.None);                }                else                {                    break;                }            }        }

js代码

 <script type=""text/javascript"">    var serverDatastatusDivws;    //var SERVER_URL = ""/Dou/T"";    window.onload = function () {        ws = new WebSocket(""ws://"" + window.location.host  + ""/Sun/T"");        serverData = document.getElementById(""serverData"");        statusDiv = document.getElementById(""statusDiv"");        startlistenServer();    }    function startlistenServer() {        statusDiv.innerHTML=""Start Connect Server..."";        //var es = new EventSource(SERVER_URL);        ws.onopen = openHandler;        ws.onerror = errorHandler;        ws.onmessage = messageHandler;    }    function openHandler(e) {        statusDiv.innerHTML = ""Server Open<br>"";    }    function errorHandler(e) {        statusDiv.innerHTML = ""Error<br>""+e.message;    }    function messageHandler(e) {        serverData.innerHTML = e.data;    }</script>

解决方案
