Question

我的问题是让我的WCF websocket服务正常运行。到现在为止，我找不到如何建立连接。客户端和服务器端都非常简单。所以我觉得我错过了一些明显的东西。

我目前在我的解决方案中有一个正常运行的WCF服务。 Web服务托管在IIS下，使用https和使用基本身份验证正确处理连接。

这是我的web.config文件：

现在我正在尝试使用WebSocketHost将WebSocket服务器托管为WCF服务。

这是我的工厂：

public class TRWebSocketServiceFactory: ServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            try
            {
                WebSocketHost host = new WebSocketHost(serviceType, baseAddresses);

                host.AddWebSocketEndpoint();
                return host;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                throw ex;
            }
        }
    }

这是服务：

public class EchoWSService : WebSocketService
    {
        public override void OnOpen()
        {
            this.Send("Welcome!");
        }

        public override void OnMessage(string message)
        {
            string msgBack = string.Format(
                "You have sent {0} at {1}", message, DateTime.Now.ToLongTimeString());
            this.Send(msgBack);
        }

        protected override void OnClose()
        {
            base.OnClose();
        }

        protected override void OnError()
        {
            base.OnError();
        }
    }

这是我的Global.asax文件：

public class Global : System.Web.HttpApplication
    {
        protected void Application_Start(object sender, EventArgs e)
        {
            RouteTable.Routes.Add(new ServiceRoute(
                "Echo", new TRWebSocketServiceFactory(), typeof(EchoWSService)));
        }
    }

以下是尝试建立连接的客户端：

    <script type="text/javascript" src="Scripts/jquery-2.0.2.js"></script>

        $().ready(function () {
            $("#btnConnect").click(function () {
                $("#spanStatus").text("connecting");
                ws = new WebSocket("wss://MyServer/Echo");
                ws.onopen = function () {
                    $("#spanStatus").text("connected");
                };
                ws.onmessage = function (evt) {
                    $("#spanStatus").text(evt.data);
                };
                ws.onerror = function (evt) {
                    $("#spanStatus").text(evt.message);
                };
                ws.onclose = function () {
                    $("#spanStatus").text("disconnected");
                };
            });
            $("#btnSend").click(function () {
                if (ws.readyState == WebSocket.OPEN) {
                    ws.send($("#textInput").val());
                }
                else {
                    $("#spanStatus").text("Connection is closed");
                }
            });
            $("#btnDisconnect").click(function () {
                ws.close();
            });
        });
    </script>
</head>

</html>

在线：

host.AddWebSocketEndpoint();

我总是得到错误：

找不到与绑定CustomBinding的端点的scheme http匹配的基址。注册的基地址方案是[https]。

我对以下几点感到困惑：

如何解决此错误？
我应该将web.config文件中的EchoWSService作为其他服务吗？
如何使用网络套接字管理基本身份验证？

谢谢！

我失踪了：

Binding binding = WebSocketHost.CreateWebSocketBinding(true);

之前：

host.AddWebSocketEndpoint();

现在端点是正确的。
