config.js

(function() {
	'use strict';

	angular
	.module('app')
	.config(config);

	config.$inject = ['$httpProvider'];

	/** @ngInject */
	function config($httpProvider) {
		$httpProvider.defaults.transformRequest = function(data){
			if (data === undefined)
			return data;

			return $.param(data);
		};

		$httpProvider.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded; charset=UTF-8;";
