How do I sniff wss (websocket) traffic that is handled in a swf?

Question

I've tried Wireshark and that doesn't show any of the wss traffic, nor do Chrome developer tools and Firefox firebug. I know for sure websocket traffic is occurring. So, how do I monitor the traffic that is occurring on my computer?

Answer 1

Run this script in Chrome's console

You can modify and send the frames to a server via ajax

(function() {
    WebSocket.prototype._send = WebSocket.prototype.send;
    WebSocket.prototype.send = function(data) {
        this._send(data);
        this.addEventListener('message', function(msg) {
            console.log('>> ' + msg.data);
        }, false);
        this.send = function(data) {
            this._send(data);
            console.log("<< " + data);
        };
    }
})();
