javascript - 错误: Not a function - Angular Service

Question

我尝试调用服务中定义的函数。

var app = angular.module('title', ['flash', 'ngAnimate', 'ngRoute'], 
    function ($interpolateProvider) {

        $interpolateProvider.startSymbol('[[');
        $interpolateProvider.endSymbol(']]');
    })

.service('getWidgets', function (globalServices, $http) {

    var getData = function() {

        var getWidgetUrl = globalServices.baseUrl + "admin/widget/list-text-widget";
        return $http({method:"GET", url:getWidgetUrl})
            .then(function(result){

                return result.data;
            });
    };

    return { getData: getData };
});

调用部分

var widget = getWidgets.getData()
    .then(function (result) {

        $scope.widgets = result;
        $scope.$apply();
    });

但它返回错误getWidgets.getData不是函数。

根本原因是什么？

更改如下:

angular.module('dss')
  .controller('widgetCtrl', 
    ['$scope', '$compile', '$window', '$location', '$http', 'globalServices', 'getWidgets', 'Flash', '$timeout', '$sce', '$routeParams', widgetCtrl]); 

   function widgetCtrl($scope, $compile, $window, $location, $http, globalServices, getWidgets, Flash, $timeout, $sce, $routeParams) { 

   var widget = getWidgets.getData(); 
   widget.then(
      function (result) { 
          $scope.widgets = result; $scope.$apply(); 
      });     
}

编辑:如果您需要建议，请使用以下语法:

widgetCtrl.$inject = ['$scope', '$compile', '$window', '$location', '$http', 'globalServices', 'getWidgets', 'Flash', '$timeout', '$sce', '$routeParams'];

angular.module('dss').controller('widgetCtrl', widgetCtrl);

function widgetCtrl($scope, $compile, $window, $location, $http, globalServices, getWidgets, Flash, $timeout, $sce, $routeParams) { 

    var widget = getWidgets.getData(); 
    widget.then( 
        function (result) { 
            $scope.widgets = result; $scope.$apply(); 
        });     
}
