NPE while connecting to netty-socketio 1.7.3 from Java Socketio Client using socket.io-1.x #179

Hi,

I am using Gottox/socket.io-java-client to connect to netty-socketio server (v1.7.3), but it is throwing a NPE as shown below. I am using the socket.io version 1.x for the connection and the URL which is sent from the client is http://localhost:9332/socket.io/1/?EIO=2&transport=polling as you can see below, an extract from log file.

Can you please let me know in case we need to send some extra parameter from the client to get it working?

Gottox/socket.io-java-client is not compatible with 1.0 protocol. Use netty-socketio 1.6.6

SharathChandraB commented 10 years ago

There is a commit on java-client which supports the socket.io 1.0 and I have tested it with node socket io server 1.0 and it works well. The issue is with connecting to this server, if you can just let me know in case we need to pass any extra parameter that would be great.

Could you watch in debug has you passed the AuthorizeHandler.authorize method?
