[Socket.IO] socket io server cannot receive message from cocos2dx client side

This is the code of my server side:
Capture

And I programmed the client side as below:
cocos2d::network::SIOClient* _sioClient = SocketIO::connect(“xxx.xxx.xx.xx:3000”, *this);
_sioClient->emit(“KKK”, “Test”);

But the server side cannot show the console log. Please help. Thanks.

Anyone help?

Do anyone know the issue? This is very critical to me… Please help, thanks!

Did you look in cpp-tests or search these forums for working example?
