在Azure Websites中使用Websockets - WebSocket握手期间出错

Question

我正在使用Azure网站。在我的ASP Net MVC项目中，我创建了一个websocket服务器和客户端。当我试图打电话给我的服务器时，我得到了

  

与'ws：//binfx.azurewebsites.net/WebSocketServer.ashx'的WebSocket连接失败：WebSocket握手期间出错：net :: ERR_CONNECTION_RESET

我的服务器类是：

WebSocketServer.ashx

public class WebSocketServer : IHttpHandler
{

    public void ProcessRequest(HttpContext context)
    {

        if (context.IsWebSocketRequest)
        {
            context.Response.ContentType = "text/plain";
            context.Response.Write("Hello World");
            context.AcceptWebSocketRequest(new MicrosoftWebSockets());
        }
        else
        {
            context.Response.ContentType = "text/plain";
            context.Response.Write("Not a websocket response!");
            context.Response.StatusCode=400;    
        }
    }
}

我的客户代码是：

Index.cshtml

 window.onload = function () {
    var conversation = $('body');
    var localHost = window.document.location.host;
    var url = "ws://" + localHost + "/WebSocketServer.ashx"; 
    if (window.WebSocket) {
        var ws = new WebSocket(url);
        ws.onmessage = function (response) {
            conversation.append(createSpan('Response:' + response.data));
        }
        ws.onopen = function (response) {
            ws.send('message!');
            conversation.append(createSpan('Azure CONNECTED'));
        }
        ws.onerror = function (e) {
            conversation.append(createSpan("There are connection issues"));
        }
    }
    else {
        alert("Your browser does not support instant messaging. You need to regularly refresh your browser in order to receive updates");
    }
}

我已启用在Azure门户中使用Websockets
