            var deferred = $q.defer();
            var url = config.basePath  + 'admins/1.html?act=login';
            $http({

                    for (var o in obj)
                        str.push(encodeURIComponent(o) + "=" + encodeURIComponent(obj[o]));
                    return str.join("&");

                data: params
            }).success(
                function (data, status, header, config) {
                    deferred.resolve(data);
                });
            return deferred.promise;
