Azure 웹 응용 프로그램 재시작 후 SignalR이 다시 연결됩니다.

Question

내 SignalR 허브를 호스팅하는 Azure 웹 응용 프로그램을 다시 시작한 후 이상한 재 연결 문제가 발생합니다. 다시 시작할 때 응용 프로그램이 DisconnectTimeout (2 분 테스트) 미만으로 다시 시작하더라도 클라이언트는 다시 연결하지 않습니다.

내가 잘못 했나요?

허브 코드

public class PingHub : Hub 
{ 
    public void Hello() 
    { 
     Clients.All.hello(); 
    } 

    public override Task OnReconnected() 
    { 
     Trace.WriteLine("Reconnect"); 
     return base.OnReconnected(); 
    } 

    public override Task OnConnected() 
    { 
     Trace.WriteLine("Connect"); 
     return base.OnConnected(); 
    } 

} 

클라이언트 코드

var hubConnection = new HubConnection("http://url/"); 


      hubConnection.TraceLevel = TraceLevels.All; 
      hubConnection.TraceWriter = Console.Out; 

      IHubProxy hubProxy = hubConnection.CreateHubProxy("PingHub"); 

      hubProxy.On("hello",() => Console.WriteLine($"Hello {DateTime.Now.ToString()}")); 

      hubConnection.Reconnected +=() => 
      { 
       Console.WriteLine("Reconnected"); 
      }; 

      hubConnection.Start().Wait();

16 : 56 : 56.7950186 - 6171c2d4-a9dd-4fa4-b710-0910af48132b -의 OnError (System.TimeoutException는 :. 분리, 0시 0분 30초 구성의 제한 내에서 다시 연결할 수있다)

한국인 아시다시피 기본값 인 DisconnectTimeout은 30 초입니다. 그리고 로그에 따르면 다시 연결하는 데 약 30 초가 걸리므로 set/change DisconnectTimeout setting in Application_Start인지 확인하십시오.

게다가 연결이 끊어진 후에도 허브에 계속 다시 연결하려면 연결이 끊긴 이벤트 처리기에서 Start 메서드를 호출 할 수 있습니다. 자세한 내용은 "How to continuously reconnect"을 참조하십시오.
