  SignalR Connection Refused

  Mar 29, 2018 12:23 PM|CSHARPER___|LINK

  Hello Everybody

  I'm using signalr for first time,

  I have a c# console application (server) and an mvc application (client)

  My Client Side Connection Code;

  <script type="text/javascript" src="~/Scripts/jquery.signalR-2.2.3.js"></script>
          <script src="http://localhost:53453/signalr/hubs"></script>
          <script>
              var sure = 2000;
              $(document).ready(function () {
  
                  $.connection.hub.url = "http://localhost:53453/signalr";
                  var chat = $.connection.Server;
                  $.connection.hub.start().done(function () {
                      chat.server.baglan("@Session["id"]");
                  });
              });
  </script>

  My server side code block

              string url = "http://localhost:53453";
              using (WebApp.Start(url))
              {
                  Console.WriteLine("SignalR Server running on {0}", url);
                  Console.Read();
              }

  Startup.cs

  public void Configuration(IAppBuilder app)
          {
              app.UseCors(CorsOptions.AllowAll);
              app.MapSignalR();
          }

  Server.cs(HUB)

  [HubName("Server")]
      public class Server:Hub
      {
          public void baglan(string uid)
          {
              string userid = uid;
  
          }
      }

  When I run the website I get these errors.Please help me to fix it.

  GET http://localhost:53453/signalr/hubs net::ERR_CONNECTION_REFUSED

  jquery.signalR-2.2.3.js:247 Uncaught Error: SignalR: Error loading hubs. Ensure your hubs reference is correct, e.g. <script src='/signalr/js'></script>.

  Is your hub really named "Server"?    var chat = $.connection.Server;

  Even if so, note that unless you decorated it with the HubName attribute, specifying the name as "Server", the first letter will be made lowercase "server" in the JS proxy.  And that's how you would reference it there.

  It will behave the same way with any server methods you might be trying to call as well.

  Thanks for your help.

  I've fixed my error with changing this

  using (WebApp.Start(url))
              {
                  Console.WriteLine("SignalR Server running on {0}", url);
                  Console.Read();
              }

  to

  WebApp.Start(url)
  
  Console.WriteLine("SignalR Server running on {0}", url);
  
  Console.Read();
