我通过引用自行托管了一个 SignalR 服务器

“未调用 Signalr Owin 简单示例 javascript 客户端”和“ https://github.com/SignalR/SignalR/wiki/Self-host ”

链接，但是当我尝试从 javascript 调用该集线器时，出现以下错误

“错误：SignalR：加载集线器时出错。确保您的集线器引用正确，例如。”

我的自托管服务器如下所示：

集线器类

using Microsoft.AspNet.SignalR; 
using System; 
using System.Collections.Generic;
using System.Linq; 
using System.Text;
using System.Threading.Tasks;
using Microsoft.Owin.Hosting;
using Owin; 
namespace SignalrWorker { 
  public class Chat:Hub
    {
       public void Send()
       {
           Clients.All.send("Hi");
       }
    } 
  }

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; 
using System.Threading.Tasks;
using Microsoft.AspNet.SignalR;
using Owin;

namespace SignalrWorker {
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // Turn cross domain on
            var config = new HubConfiguration { EnableCrossDomain = true ,EnableJavaScriptProxies=true,EnableDetailedErrors=true};

            // This will map out to http://localhost:8080/signalr by default
            app.MapHubs(config);
        }
    } 
}

using System.Net; 
using System.Threading; 
using Microsoft.WindowsAzure; 
using Microsoft.WindowsAzure.Diagnostics; 
using Microsoft.WindowsAzure.ServiceRuntime;

using Microsoft.AspNet.SignalR;
using Owin; 
using Microsoft.Owin.Hosting;

namespace SignalrWorker {
    public class WorkerRole : RoleEntryPoint
    {
        public override void Run()
        {
            // This is a sample worker implementation. Replace with your logic.
            Trace.TraceInformation("SignalrWorker entry point called", "Information");
            try
            {


                using (WebApp.Start<Startup>("http://127.0.0.1:82/"))
                {
                    Trace.TraceInformation("Working", "Server running at http://127.0.0.1:82/");
                }


                while (true)
                {
                    Thread.Sleep(10000);
                    Trace.TraceInformation("Working", "Information");

                }
            }
            catch (Exception ex)
            {
                Thread.Sleep(1000);
                Trace.WriteLine("Error", ex.Message);
            }
        }

        public override bool OnStart()
        {
            // Set the maximum number of concurrent connections
            ServicePointManager.DefaultConnectionLimit = 12;

            // For information on handling configuration changes
            // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.

            return base.OnStart();
        }
    } 
}
