How to see ping pong in web socket in iOS

问题

I am doing websocket between webview in iOS and Socketserver.

But I am unable to watch ping-pong that happens because javascript does not have any call back methods for it.

回答1:

Use Charles Proxy

It has a tab called WebSocket that shows all web socket related conversations including frames such as Ping,Pong and Close.
