angularjs $http - why not get json?

I use the ionic framework why not get json?

.controller('SearchCtrl', function($scope,$http) {
    $http({method: 'GET', url: 'dwz.cn/create.php?url=www.qq.com'}).success(function(data)
    {
        $scope.= myUrl; // response data 
    });
})

view：

<ion-view title="url">
  <ion-content class="has-header padding">
           {{myurl}}
  </ion-content>
</ion-view>

but This can be

.controller('SearchCtrl', function($scope,$http) {
    $http({method: 'GET', url: 'new.json'}).success(function(data)
    {
        $scope.= myUrl; // response data 
    });
})
