Question

我刚刚交了一个新项目，大部分工作已经完成，但我需要为项目更改一些内容。我在consoleapp中有一个这样的自托管服务器设置：

        using (var server = new HttpSelfHostServer(config))
        {
            server.OpenAsync().Wait();
            Console.WriteLine("Press enter to exit");
            Console.ReadLine();
        }

和这样配置的路线：

        private static HttpSelfHostConfiguration CreateWebServerConfiguration()
    {
        var config = new HttpSelfHostConfiguration(string.Format("http://{0}:{1}", Environment.MachineName, 80));

        config.Routes.MapHttpRoute("Api", "api/{controller}/{id}/{value}", new {id = RouteParameter.Optional, value = RouteParameter.Optional });
        config.Routes.MapHttpRoute("Defect", "defect/{action}/{id}", new { controller = "Defect", action = RouteParameter.Optional, id = RouteParameter.Optional });
        config.Routes.MapHttpRoute("Content", "content/{action}/{file}", new { controller = "Content"});
        config.Routes.MapHttpRoute("Default", "{controller}/{action}/{id}/{date}", new { controller = "Home", action = "Index", id = RouteParameter.Optional, date = RouteParameter.Optional });

        var templateConfig = new TemplateServiceConfiguration { Resolver = new DelegateTemplateResolver(name => ReadFileContent("Views", name))};

        Razor.SetTemplateService(new TemplateService(templateConfig));
        return config;
    }

这很好用，但我遇到了一种情况，我不希望前端用服务器上的计时器拉（当前每5分钟自动刷新一次）。当需要更新新内容时，我希望服务器更新前端。我找到了解决方案，这将是websockets，但我有很多问题使用它们。

我的.js文件：

        (function() {
        if ("WebSocket" in window) {
            alert("WebSocket is supported by your Browser!");
        } ws://' + window.location.hostname + window.location.pathname.replace('index.htm', 'ws.ashx') + '?name=' 
        var socket = new WebSocket("ws://localhost:80/WebsocketServer.cs");

        socket.onmessage = function(event) {
            alert("message recv.");
            alert(event.data);
        };
        socket.onopen = function() {
            alert("open");
        }
        socket.onerror = function(errorEvent) {
            alert("Error");
            alert(errorEvent);
        };
        socket.onclose = function(closeEvent) {
            alert(closeEvent.code);
        }
    })();

我找到了多个像这样的例子：https://blog.simpleisbest.co.uk/2012/05/01/websockets-with-asp-net-4-5-and-visual-studio-11/但它似乎对我不起作用，这是我的文件：

WebsocketServer.cs

    public class WebsocketServer : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        if (context.IsWebSocketRequest)
        {
            context.AcceptWebSocketRequest(new WebSocketManager());
        }
    }

    public bool IsReusable
    {
        get { return false; }

    }
}

WebSocketManager.cs

    public class WebSocketManager : WebSocketHandler
{
    public static WebSocketCollection clients = new WebSocketCollection();
    public override void OnClose()
    {
        clients.Remove(this);
    }
    public override void OnError()
    {

    }
    public override void OnMessage(string message)
    {

    }
    public override void OnOpen()
    {
        clients.Add(this);
        clients.Broadcast("Connected");
    }
}

前端返回结束代码1006或CLOSE_ABNORMAL。我的猜测是没有创建后端的链接？
