Question

在我的服务器端，我只有一个由MVC构成的简单服务器端

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手机客户端

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

中

_client = new Client("Windows");

在我部署Connect之后调用Hub时，它会抛出一个异常，但响应为

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

我在这里遗漏了什么吗？我还检查了reference如何解决问题，但我似乎对他们的指导方针没问题。

Windows Phone 8模拟器是一个虚拟机。这意味着“localhost”引用VM / phone，而不是运行IIS / IISExpress的主机。

您可以使用其主机名或IP地址连接到主机。

如果您决定坚持使用IIS Express，则需要将Windows防火墙配置为接受运行IIS Express的任何端口上的入站请求。

How to connect to a local web service from the Windows Phone 8 emulator上的指南侧重于WCF，但同样适用于SignalR。

无法连接到Hub
