javascript - 在 Angularjs 的响应中获取 Promise 数据

Question

我有如下一项服务

getServices.js

angular
    .module('adminsuite')
    .service('getAllSurveyService', getAllSurveyService);
    getAllSurveyService.$inject = ['$http', '$cookieStore', '$rootScope', '$timeout', '$q'];
     function getAllSurveyService($http,$cookieStore,$rootScope,$timeout,$q){
        var deferred = $q.defer();
        var session = $cookieStore.get('globals');
        var data = {
            sessionId : session.currentUser.session
        }
        var surveyData = {
            'Data' : JSON.stringify(data)
        }
        var requestData = JSON.stringify(surveyData)
        //console.log(requestData);

        this.surveyList = function () {
            //return session;
            return $http.post('http://apidev.1pt.mobi/V3.0/api/Survey/Surveys',  requestData, {headers: { 'Content-Type': 'application/json'}})
            .then(function(response){
                        var sendData = deferred.resolve(response.data);
                        //console.log(JSON.stringify(response.data));
                        return response.data;
                    }, function(error){
                        return error;
                    });
        }

    };

下面的 Controller 我用来获取数据

controller.js

angular.module("adminsuite").controller("surveyController",['getAllSurveyService', '$scope', function(getAllSurveyService, $scope){
    $scope.header = "Header";
    $scope.allSurveys = getAllSurveyService.surveyList();
    console.log($scope.allSurveys);
    //console.log($scope.getSession);
 }]);

在控制台中得到这样的响应

在此之后，我尝试获取 Promise 对象内的数据，但无法获取该数据。

getAllSurveyService.surveyList() 返回一个 promise ，因此您需要获取如下数据(在您的 Controller 中):

getAllSurveyService.surveyList().then(
    function( data ) {
        $scope.allSurveys = data;
        console.log($scope.allSurveys);
    }
);
