Window Client does not properly convert special character "[" & "]"

Question

User1336195024 posted

I'm using service fabric and reverse proxy for the server side.

While connecting through my window client to the reverse proxy, the connection keep failing with Error FABRIC_E_INVALID_ADDRESS. After investigate using fiddler, I notice my window client is sending this http request: 

http://xxx/signalr/negotiate?clientProtocol=1.4&connectionData=[%7B"Name":"SignalRHub"%7D]%20HTTP/1.1

I had google around and notice it is a known issue where service fabric having problem to handler these special character "[" & "]". 

Is there any work around for this to change the "[" to "%5B" ?

I just figured myself that I can overwrite class the HubConnection to encode the connectionData. :)

public class CustomHubConnection: HubConnection
  {
      public CustomHubConnection(string url) : base(url) { }
 
      protected override string OnSending()
      {
          var connectionData = base.OnSending();
          connectionData = WebUtility.UrlEncode(connectionData);
          return connectionData;
      }
  }
