Angular module to make $http behave like jQuery AJAX

http-provider.js

angular.module('http-provider', [], function($httpProvider) {
	// http://victorblog.com/2012/12/20/make-angularjs-http-service-behave-like-jquery-ajax/
	// Use x-www-form-urlencoded Content-Type
	$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
 
	var param = function(obj) {
		var query = '', name, value, fullSubName, subName, subValue, innerObj, i;
      
		for(name in obj) {
    value = obj[name];
			if(value instanceof Array) {
				for(i=0; i<value.length; ++i) {
					subValue = value[i];
					fullSubName = name + '[' + i + ']';
					innerObj = {};

    }

	};
	// Override $http service's default transformRequest
	$httpProvider.defaults.transformRequest = [function(data) {
		return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
	}];
});
