Send a query to phabricator using node.js

conduit.apiquery.js

var ApiQuery = function() {
	this.http = require('http');
	this.q = require('q');
	this.Connect = require('./conduit.connect');

	this.initialize();
};

ApiQuery.prototype = {
	initialize: function() {
		this.connect = new this.Connect();
	},

	send: function(api, params) {
		params = params || {};
		var deferred = this.q.defer();

		console.log('Received send:', api, params);

		this.connect.toFirst().then(function(attrs) {
			console.log('Succesfully authed');
			params.__conduit__ = {
				connectionID: attrs.connectionID,
				sessionKey: attrs.sessionKey
			};
			
			var	formData = 'params='+JSON.stringify(params)+'&output=json&__conduit__=1',
				postOptions = {
					host: attrs.host.host,
					port: 80,
					path: '/api/' + api,
					method: 'POST',
					headers: {
						'Content-Type': 'application/x-www-form-urlencoded',
						'Content-Length': Buffer.byteLength(formData)
					}
				},
				postReq = this.http.request(postOptions, function(res) {
					console.log('Send response:', res);
					res.setEncoding('utf8');

					res.on('error', function(e) {
						console.log('Error sending post:', e);
					});

					res.on('data', function(data) {
						console.log('Received send data:', data);
						deferred.resolve(data);
					});
				});

			postReq.end(formData, 'utf8');
		});

		return deferred.promise;
	}
};

module.exports = ApiQuery;

Note: formData doesn't use something like qs.stringify on the whole object as Phabricator strangely expects only the stuff in params to be in quotes.
