无法连接集线器

Question

在我的服务器端，我只有一个简单的MVC服务器端。

和

public class Chat : Hub
{
    public void Send(string platform, string message)
    {
        Clients.All.messageReceived(platform, message);
    }
}

和

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

我的windows客户端

public class Client
{
    private readonly string _platform;
    private readonly HubConnection _connection;
    private readonly IHubProxy _proxy;

    public event EventHandler<string> OnMessageReceived;

    public Client(string platform)
    {
        _platform = platform;
        _connection = new HubConnection("http://localhost");
        _proxy = _connection.CreateHubProxy("Chat");

    }

    public async Task Connect()
    {
         await _connection.Start();

        _proxy.On("messageReceived", (string platform, string message) =>
        {
            if (OnMessageReceived != null)
                OnMessageReceived(this, string.Format("{0}: {1}", platform, message));
        });

        await Send("Connected");
    }

    public Task Send(string message)
    {
        return _proxy.Invoke("Send", _platform, message);
    }
}

在我的MainWindow.xaml.cs里

_client = new Client("Windows");

当我在部署Connect之后调用Hub时，它会抛出一个异常，其响应为

{StatusCode: 404, ReasonPhrase: '', Version: 0.0, Content: System.Net.Http.StreamContent, Headers: { Content-Length: 0 }}

我是不是漏掉了什么？我还检查了参考文献如何解决问题，但我似乎对他们的指导原则很满意。

Windows 8模拟器是一台虚拟机。这意味着"localhost“引用的是VM/phone，而不是运行IIS/IISExpress的主机。

您可以使用主机名或IP地址连接到主机。

如果您决定坚持使用IIS Express，则需要配置Windows防火墙，以便在IIS Express运行的任何端口上接受入站请求。

关于如何从Windows 8模拟器连接到本地web服务的指南侧重于WCF，但同样适用于SignalR。
