Angular Js：'$ q.defer不是函数'错误

After Refering this Link , I am trying to get JSON data into my angular service.

在引用此链接之后，我正在尝试将JSON数据放入我的角度服务中。

Service:

服务：

.factory('restservice', ['$rootScope','$http', '$q', '$log',
function($rootScope,$q, $http) {
return {
    getData: function() {
        var defer = $q.defer();
        $http.get('xyz.com/abc.php', { cache: 'true'})
        .success(function(data) {
            defer.resolve(data);
        });

        return defer.promise;
      }
};
}])

Controller:

控制器：

.controller('RestaurantsCtrl', function ($scope,$http, restservice,restViewservice){

      restservice.getData().then(function(data) {
      $scope.Restaurants = data;
    });

})

After Implementing this console says '$q.defer is not a function'.

实现此控制台后说'$ q.defer不是函数'。

What's the issue here? Please Help ...!! Am new to Angular Js so forgive if something is wrong.

You have wrong service definition:

您的服务定义错误：

factory('restservice', ['$rootScope','$http', '$q', '$log',
function($rootScope,$q, $http) {

Should be:

应该：

factory('restservice', ['$rootScope','$http', '$q', '$log',
function($rootScope,$http, $q, $log) {

_{Common mistake :)}
