具有Mosync移动客户端应用程序的SignalR Server桌面应用程序

Question

现在，我正在使用SignalR在c＃（visual Studio 2012）中开发服务器桌面应用程序。

使用Mosync Mobile应用程序的客户端应用程序（独立于移动平台）

当服务器应用程序和客户端应用程序位于同一台计算机（本地主机）上时，通信已成功创建，并且从服务器到客户端的数据馈送正常运行。 但是，当我将服务器应用程序放在远程服务器中时，Mosync客户端应用程序无法与服务器通信。 有人可以帮我吗？

服务器端代码：

    public partial class Form1 : Form
    {
    private IDisposable signalR { get; set; }
    const string ServerURI = "http://localhost:8080";
    MyHub h = new MyHub();
    public Form1()
    {
        InitializeComponent();
    }

    private void btnServerStart_Click(object sender, EventArgs e)
    {
        writeToConsole("Starting server...");
        btnServerStart.Enabled = false;
        Task.Run(() => StartServer());
    }
    private void StartServer()
    {
        try
        {
            signalR = WebApp.Start(ServerURI);

        }
        catch (TargetInvocationException)
        {
            writeToConsole("Server failed to start. A server is already running on" + ServerURI);
            this.Invoke((Action)(() => btnServerStart.Enabled = true));
            return;
        }

        {

            return;
        }

    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)

    }
    private void btnSend_Click(object sender, EventArgs e)
    {
        string msg = txtMessage.Text;
        h.Receive(msg);
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        string message = "hi";
       // h.Receive(message);
    }


}
class Startup
{
    public void Configuration(IAppBuilder app)
    {
        app.UseCors(CorsOptions.AllowAll);
        app.MapSignalR();
    }
}
public class MyHub : Hub
{
    public void Send(string name, string message)
    {
        Clients.All.addMessage(name, message);
        Program.mainform.writeToConsole(name + " : " + message);
    }
    public void Receive(string msg)
    {
        var context = GlobalHost.ConnectionManager.GetHubContext<MyHub>();
        context.Clients.All.addMessage("Admin", msg);
    }
    public override Task OnConnected()
    {
        Program.mainform.writeToConsole("Client Connected:" + Context.ConnectionId);

        return base.OnConnected();
    }
    public override Task OnDisconnected(bool stopCalled)
    {
        Program.mainform.writeToConsole("Client DisConnected: " + Context.ConnectionId);
        return base.OnDisconnected(stopCalled);
    }

}

}

乍一看，假设您的代码可以，那么它可能是IIS或网络/基础结构问题。 您是否调查过这种可能性？

IIS 7.0和7.5支持SignalR，但必须添加对无扩展名URL的支持。 要添加对无扩展名URL的支持，请参阅http://support.microsoft.com/kb/980368
