SocketIO.State is always None about socket.io-client-csharp

[doghappy]

SocketIO.State is always None, the possible reason is: not connected to the server yet

When the data returned by the server starts with 40, it indicates that the connection is successfully established.

Our socket URI is http://<my_ip>:<my_port>/notification

When the data returned by the server starts with 40, the ConnectHandler method is not called because ctx.Namespace is '/Notification,'

[bpcuong2013]

We also received data that starts with '40/notification', but ConnectHandler is still not called because of missing common character.

[doghappy]

you got 40/notification instead of 40/notification, ?

[bpcuong2013]

Exactly, I got 40/notification

You can change the code, add .TrimEnd(",")

 class ConnectedParser : Parser 
 { 
     public override void Parse(ParserContext ctx, ResponseMessage resMsg) 
     { 
         if (resMsg.Text == "40" + ctx.Namespace.TrimEnd(",")) 
         { 
             ctx.ConnectHandler(); 
         } 
         else if (Next != null) 
         { 
             Next.Parse(ctx, resMsg); 
         } 
     } 
 } 

I need to do some related research
