Question

我正在尝试使用MVC设置一个示例Angular.js项目。

我让项目只是从控制器返回一条消息。但是，当我尝试从WebApi读回工厂时，我在运行时收到以下错误。

 AngularTutorial?v=exNgsrzkUJRjHARMvxI_00QqlywTra533io1LcIemD81:1 Uncaught ReferenceError: HomeFactory is not defined(anonymous function) @ AngularTutorial?v=exNgsrzkUJRjHARMvxI_00QqlywTra533io1LcIemD81:1

以下是似乎导致此问题的文件。

AngularTutorial.js

var AngularTutorial = angular.module('AngularTutorial', []);

AngularTutorial.controller('HomeController', HomeController);

AngularTutorial.factory('HomeFactory', HomeFactory);

HomeFactory.js

var HomeFactory = function($http, $q) {
    return function() {
        var deferredResult = $q.defer();

        $http.get('http://localhost:52506/api/message/get')
            .success(function(data) {
                deferredResult.resolve(data);
            });
        return deferredResult.promise;
    }
}
HomeFactory.$inject = ['$http', '$q'];

的HomeController

var HomeController = function ($scope, HomeFactory) {

    HomeFactory().then(function(response) {
        $scope.message = response;
    });
}
HomeController.$inject = ['$scope', 'HomeFactory'];

如果有任何帮助，我已经包含了整个解决方案的链接。

参见以下示例

＆＃13;

var AngularTutorial = angular.module('AngularTutorial', []);

AngularTutorial.factory('HomeFactory', [
  '$http',
  '$q',
  function($http, $q) {
    return function() {
      return $http.get('http://localhost:52506/api/message/get');
    }
  }
]);


AngularTutorial.controller('HomeController', [
  '$scope',
  'HomeFactory',
  function($scope, HomeFactory) {
    HomeFactory().then(function(response) {
      $scope.message = response;
    });
  }
]);

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="AngularTutorial">
  <div ng-controller="HomeController">
    {{message}}
  </div>
</div>

无需在工厂中创建deferred对象。 $http.get也只返回承诺所以，您只需返回$http.get(/*URL*/)即可。
