threez / node-http-parser.js

Created January 23, 2014 07:42

	var HTTPParser = process.binding('http_parser').HTTPParser;
	var parser = require("http").parsers.alloc();
	parser.reinitialize(HTTPParser.RESPONSE);

	parser.onBody = function(body) {
	console.log(body.toString());

	parser.onIncoming = function(response) {
	console.log(response.headers);
	console.log(response.statusCode);
