SignalR 2.0.0.0：$ .connection is undefined

我想運行我的第一個SignalR v2項目，但沒有運氣，$ .connection是未定義的。

下面是從Web控制檯錯誤：

遺漏的類型錯誤：無法讀取未定義（匿名函數）的特性 'chatHub'

我的樞紐：

using Microsoft.AspNet.SignalR; 

namespace InstantMessage 
{ 
    public class ChatHub : Hub 
    { 
     public void Hello() 
     { 
      Clients.All.hello(); 
     } 
    } 
}

Startup.cs

using Microsoft.Owin; 
using Owin; 

[assembly: OwinStartup(typeof(InstantMessage.Startup))] 
namespace InstantMessage 
{ 
    public class Startup 
    { 
     public void Configuration(IAppBuilder app) 
     { 
      app.MapSignalR(); 
     } 
    } 
}

      $('#message').focus(); 
      // Start the connection. 
      $.connection.hub.start().done(function() { 
       $('#sendmessage').click(function() { 
        // Call the Send method on the hub. 
        chat.server.send($('#displayname').val(), $('#message').val()); 
        // Clear text box and reset focus for next comment. 
        $('#message').val('').focus();

好像在/ signalr /集線器的js代碼是正確的，chathub是存在的，文件工作的自動生成精細。

$.hubConnection.prototype.createHubProxies = function() { 
     var proxies = {}; 
     this.starting(function() { 
      // Register the hub proxies as subscribed 
      // (instance, shouldSubscribe) 
      registerHubProxies(proxies, true); 

      this._registerSubscribedHubs(); 
     }).disconnected(function() { 
      // Unsubscribe all hub proxies when we "disconnect". This is to ensure that we do not re-add functional call backs. 
      // (instance, shouldSubscribe) 
      registerHubProxies(proxies, false); 
     }); 

     proxies.chatHub = this.createHubProxy('chatHub'); 
     proxies.chatHub.client = { }; 
     proxies.chatHub.server = { 
      hello: function() { 
       return proxies.chatHub.invoke.apply(proxies.chatHub, $.merge(["Hello"], $.makeArray(arguments))); 
      } 
     }; 

     return proxies; 
    };

還應該提一下，我從nuget安裝Signalr，我使用VS2012。

是你的腳本中的元標記包括以正確的順序？ – davidfowl

在app.MapSignalR（）上設置調試斷點，看看是否實際上生成了「/ signalr/hubs」路徑 –

是的，它們全部包含在內，如下所示：是的，當我在app.MapSignalR（）上添加一個斷點我在應用程序啓動時點擊它。但它仍然拒絕工作.. –
