I want to use socket.io client Post My topic to my website.

I find nodebb post code:

	if (parseInt(postData.cid, 10) > 0) {
		socket.emit('topics.post', {
			title: titleEl.val(),
			content: bodyEl.val(),
			topic_thumb: thumbEl.val() || '',
			category_id: postData.cid
		}, done);

How I do get cookies(login user info). use by socket.io client.

1、Can I get data format？
2、websocket use port 80？
3、Can I write a test example to send topic by websocket ?

When we send new topic to server. We send title,content to (server) http://commiunity.nodebb.org/topic/xxxx/ .
The server receive the POST and save it.

Generic request ,Chrome can capture it. but nodebb send topic request. chrome can't capture.
Chrome capture demo:

I can't get network request when I use Chrome and firebug(In firefox) send a New Topic.
