我认为更好的方式是这样的:

服务:

app.service('FruitsManager',function($q){

    function getAllFruits(){
        var deferred = $q.defer();

        ...

        // somewhere here use: deferred.resolve(awesomeFruits);

        ...

        return deferred.promise;
    }

    return{
        getAllFruits:getAllFruits
    }

});

在控制器中，你可以简单地使用:

$scope.fruits = FruitsManager.getAllFruits();

Angular会自动把解析后的awesomfruits放到$scope.fruits中。

Tosh shimayama有一个解决方案，但你可以简化很多，如果你使用$http返回承诺，承诺可以返回一个值:

app.factory('myService', function($http, $q) {
  myService.async = function() {
    return $http.get('test.json')
    .then(function (response) {
      var data = reponse.data;
      console.log(data);
      return data;
    });
  };

  return myService;
});

app.controller('MainCtrl', function( myService,$scope) {
  $scope.asyncData = myService.async();
  $scope.$watch('asyncData', function(asyncData) {
    if(angular.isDefined(asyncData)) {
      // Do something with the returned data, angular handle promises fine, you don't have to reassign the value to the scope if you just want to use it with angular directives
    }
  });

});

请尝试下面的代码

你可以分离控制器(PageCtrl)和服务(dataService)

'use strict'; (function () { angular.module('myApp') .controller('pageContl', ['$scope', 'dataService', PageContl]) .service('dataService', ['$q', '$http', DataService]); function DataService($q, $http){ this.$q = $q; this.$http = $http; //... blob blob } DataService.prototype = { getSearchData: function () { var deferred = this.$q.defer(); //initiating promise this.$http({ method: 'POST',//GET url: 'test.json', headers: { 'Content-Type': 'application/json' } }).then(function(result) { deferred.resolve(result.data); },function (error) { deferred.reject(error); }); return deferred.promise; }, getABCDATA: function () { } }; function PageContl($scope, dataService) { this.$scope = $scope; this.dataService = dataService; //injecting service Dependency in ctrl this.pageData = {}; //or []; } PageContl.prototype = { searchData: function () { var self = this; //we can't access 'this' of parent fn from callback or inner function, that's why assigning in temp variable this.dataService.getSearchData().then(function (data) { self.searchData = data; }); } } }());

我读过http://markdalgleish.com/2013/06/using-promises-in-angularjs-views/ [AngularJS允许我们通过直接在作用域上放置承诺来简化我们的控制器逻辑，而不是在成功回调中手动处理已解析的值。]

如此简单和方便:)

var app = angular.module('myApp', []);
            app.factory('Data', function($http,$q) {
                return {
                    getData : function(){
                        var deferred = $q.defer();
                        var promise = $http.get('./largeLoad').success(function (response) {
                            deferred.resolve(response);
                        });
                        // Return the promise to the controller
                        return deferred.promise; 
                    }
                }
            });
            app.controller('FetchCtrl',function($scope,Data){
                $scope.items = Data.getData();
            });

希望这对你有所帮助

简单点。这很简单

在您服务期间退货承诺(在您服务期间无需使用) 在你的控制器中使用then

演示。http://plnkr.co/edit/cbdG5p?p=preview

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

app.factory('myService', function($http) {
  return {
    async: function() {
      return $http.get('test.json');  //1. this returns promise
    }
  };
});

app.controller('MainCtrl', function( myService,$scope) {
  myService.async().then(function(d) { //2. so you can use .then()
    $scope.data = d;
  });
});

我也有同样的问题，但当我在互联网上冲浪时，我明白$http返回默认的承诺，然后我可以在返回“数据”后使用“然后”。看看代码:

 app.service('myService', function($http) {
       this.getData = function(){
         var myResponseData = $http.get('test.json').then(function (response) {
            console.log(response);.
            return response.data;
          });
         return myResponseData;

       }
});    
 app.controller('MainCtrl', function( myService, $scope) {
      // Call the getData and set the response "data" in your scope.  
      myService.getData.then(function(myReponseData) {
        $scope.data = myReponseData;
      });
 });
