javascript - 使 Angular HTTP 调用可重用

Question

在我的 controller.js 中，我有一个 HTTP GET 请求，当我的页面加载和用户拉取刷新时，我必须调用该请求。

我现在的做法是复制 $http 代码。有没有办法让它更可重用？我不知道如何将其移动到我的 services.js 文件并在我的 Controller 中引用它以便它运行。

.controller('GamesCtrl', function ($scope, $http) {
  $http(
  {
      method: 'GET',
      url: 'https://www.kimonolabs.com/api/dc6n4edu?apikey=U4SNiysE89aaLXSWRJgHKDZOByqSLM0p',
      headers: {
          'authorization': 'Bearer PW8V4OesZ61tCqSRNpXYtRn5ahcLdclU'
      }
  }).
  success(function (data) {
      $scope.data = data['results']['collection1'];
  });

  $scope.doRefresh = function() {
    $http(
          {
              method: 'GET',
              url: 'https://www.kimonolabs.com/api/dc6n4edu?apikey=U4SNiysE89aaLXSWRJgHKDZOByqSLM0p',
              headers: {
                  'authorization': 'Bearer PW8V4OesZ61tCqSRNpXYtRn5ahcLdclU'
              }
          }).
          success(function (data) {
              $scope.data = data['results']['collection1'];
          })
     .finally(function() {
       $scope.$broadcast('scroll.refreshComplete');
     });
  };
})

简单的答案是，创建一个私有(private)函数:

.controller('GamesCtrl', function ($scope, $http) {
  var doLoad = function() {
      $http(
      {
          method: 'GET',
          url: 'https://www.kimonolabs.com/api/dc6n4edu?apikey=U4SNiysE89aaLXSWRJgHKDZOByqSLM0p',
          headers: {
              'authorization': 'Bearer PW8V4OesZ61tCqSRNpXYtRn5ahcLdclU'
          }
      }).
      success(function (data) {
          $scope.data = data['results']['collection1'];
      }).finally(function() {
       $scope.$broadcast('scroll.refreshComplete');
     });;
  };

  $scope.doRefresh = function() {
    doLoad();
  };

  doLoad();
})

更详细的答案可能是将其提取到服务中:

.service('KimonoSvc',function($http) {
    return {
      get: function() {
         return $http(
         {
             method: 'GET',
             url: 'https://www.kimonolabs.com/api/dc6n4edu?apikey=U4SNiysE89aaLXSWRJgHKDZOByqSLM0p',
             headers: {
                 'authorization': 'Bearer PW8V4OesZ61tCqSRNpXYtRn5ahcLdclU'
             }
         });
      }
    };
})
.controller('GamesCtrl', function ($scope, KimonoSvc) {
  var doGet = function() {
    KimonoSvc.get().
         success(function (data) {
             $scope.data = data['results']['collection1'];
         }).finally(function() {
          $scope.$broadcast('scroll.refreshComplete');
        });
  };
  $scope.doRefresh = function() {
    doGet();
  };

  doGet();
})
