如何使用$ resource获取状态代码? [英] How can I get status code using $resource?

问题描述

我的提出要求的工厂在这里:

My factory for making request is here:

angular.module('myapp').factory('testResponse',
        ['$http', '$resource', 'AppConfig', '$routeParams', '$rootScope',
            function($http, $resource, $routeParams, $rootScope) {
                $http.defaults.headers.common['Authorization'] = authorizationHeader;
                $http.defaults.headers.post['Content-Type'] = 'application/json';
                return $resource('test.json'), {}, {
                    query: {method: 'GET'}
                };
            }]);

控制器中的代码在这里:

The code in controller is here:

angular.module('myapp').controller('TestCtrl',
        ['$http', '$scope', 'testResponse', 'AppConfig', function TestCtrl($http, $scope, testResponse) {
                testResponse.query(function(data) {
                    console.log(data.status);
                })
            }]);

理想情况下，它应该记录$ http请求中的状态，但我无法获得$ reource的状态

Ideally it should log the status as in $http request but I am unable to get it for $reource

推荐答案

我尝试对$ q使用诺言来处理这种情况，在这种情况下，我必须对失败或成功进行更多控制. 我像下面这样重构工厂:

I tried use promises with $q to handle this kind of scenario where I had to have more control on failure or success. I refactored the factory like here:

var defObj = $q.defer();
  var testResponse = $resource('https://jsonplaceholder.typicode.com/posts/1', {}, {
    query: {
      method: 'GET'
    }
  });
  testResponse.query().$promise.then(function(data) {
    //you can add anything else you want inside this function
    defObj.resolve(data);
    console.log(defObj, data);
  }, function(error) {
    //you can add anything else you want inside this function
    console.error("Service failure: " + error);
  });
  return defObj.promise;
}

这是这支笔中的完整解决方案(使用模拟json来模拟响应)

Here is the complete solution in this pen (uses mock json to simulate the response)
