Question

我有两个带有Windows身份验证的asp.net应用程序 应用A：有SignalR中心

[HubName("docHub")]
public class DocumentHub : Hub
{
    private static IHubContext hubContext = GlobalHost.ConnectionManager.GetHubContext<DocumentHub>();

    public void ReloadMenu()
    {
        Clients.All.ReloadMenu();
    }

    public void Reload()
    {
        Clients.All.Reload();
    }
}

应用B：使用App A调用SignalR client的中心方法

public void CallHub()
{
    var url = string.Format("http://{0}/signalr/", HttpContext.Current.IsDebuggingEnabled ? "localhost:2051" : "kms.local");
    var hubConn = new HubConnection(url, false);
    hubConn.Credentials = System.Net.CredentialCache.DefaultCredentials;
    var hubProxy = hubConn.CreateHubProxy("docHub");
    hubConn.Start().Wait();
    hubProxy.Invoke("Reload");
    hubProxy.Invoke("ReloadMenu");
}

我的问题是hubConn.Start().Wait();行问题，我得到Unauthorized例外。堆栈跟踪：

   at Microsoft.AspNet.SignalR.TaskAsyncHelper.TaskRunners`2.<>c__DisplayClass3_0.<RunTask>b__0(Task`1 t)

由于这两个应用都有Windows身份验证方法，我不知道如何授权应用b的请求。

从另一个应用程序使用SignalR hub
