  SignalR authorization problem

  Dec 14, 2012 02:58 PM|LINK

  Hi,

  I have a scenario that I have a windows forms application that is using SignalR and a website. The client app is authenticated on the website using FormsAuthentication and the calls a Hubmethod with the [Authorize] attribute. Everything works find when I debug both application on same machines. Once I deploy website on one server and win app on another machine hub methods with authorized attribute do not work.

  Why is this happening. Is there any bug on this?

  Can you try looking at the HTTP requests to see what cookies are/aren't being passed? Also, what you're client code looks like.

  My code is the following.

  void Connect(Cookie authCookie)
          {
              string str = "Test";
              double Val = 1000;
  
              HubConnection hubConn = new HubConnection("http://10.10.10.10");
  
              CookieContainer cookieCont = new CookieContainer();
              hubConn.CookieContainer = cookieCont;
              hubConn.CookieContainer.Add(authCookie);
  
              IHubProxy Proxy = hubConn.CreateHubProxy("myHub");
  
              hubConn.Start().Start();
  
              Proxy.Invoke("getTheStuff", new JavaScriptSerializer().Serialize(new CustomModel()
                                  {
                                      Name = str,
                                      Value = Val
                                  }));
          }

  The Hub

   [Authorize]
          public void GetTheStuff(string Message)
          {
              JavaScriptSerializer jss = new JavaScriptSerializer();
              CustomModel cp = jss.Deserialize<CustomModel>(Message);
   
              if (cp != null)
                  Clients.All.sendTheStuff(cp);
   
          }

  Your code has a few issues:

  • The call to hubConn.Start().Start() should probably be hubConn.Start().Wait()
  • The second argument to Proxy.Invoke can just be your CustomModel instance, we'll serialize it for you.
  • On the Hub, GetTheStuff can simply accept a parameter typed as CustomModel, we'll deserialize it for you.

  Can you please take a look at the sample at https://github.com/davidfowl/MessengR

  This shows a WPF client talking to an ASP.NET app using Forms auth and SignalR.

  Sorry for this (syntax error)

  Serialization/Deserialization as you described it works only on my pc. When I take this on production server it does not work.

  When you say "it doesn't work on your production server". What exactly do you mean? What specific error message are you getting?

  It does not return any error. When the signalr sends the object, the event on the other end which is subscribed to listen simply does not get fired
