SignalR Hub连接授权错误

Question

当尝试连接到在同一Web应用程序中运行的SignalR集线器时，我收到401错误（未经授权）。我可以在OnConnected（）方法中放置一个断点，看看我正在访问我的集线器。 Google Chrome中出现此错误。在IE中测试，它工作正常。

客户端代码（JS）：

    var connection = $.hubConnection();
    proxy = connection.createHubProxy('myHub');
    connection.start();  // error occurs here

服务器代码（C＃）

public class MyHub: Hub
{
    public override Task OnConnected()
    {
        return base.OnConnected();  // I hit this breakpoint
    }

    public void AddLogItem()
    {
        Clients.All.logItemReceived("Adding a log item @ " + DateTime.Now);
    }
}

错误：

WebSocket connection to 'ws://localhost:50303/signalr/connect?transport=webSockets&clientProtocol=1.4&connectionToken=gEGkgEb740vzdMSFcFIfNev1d%2BFP0A9tqPaXGRT84RNSZwLDDShUKFd36fdN1Xx1heMZT3d%2BO0EkvRFtkB%2BZIwh39qcekTn94tUPyrMfX1jiIHAdhHwvGVUUJkLHTUnLxvBBPhU1FIZEn0JuLjFHYQ%3D%3D&connectionData=%5B%7B%22name%22%3A%22jcsecurehub%22%7D%5D&tid=6' failed: Error during WebSocket handshake: Unexpected response code: 401 

其他启动代码：

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.MapSignalR();
    }
}
