Angularjs：添加服务angular.module [英] Angularjs: add service to angular.module

问题描述

我想在angular.module使用服务。

I want use a service in a angular.module.

我有一个 record.js 为 RecordCtrl ，我想用 requestCurrentUser 中存在的 sessionService.js 。我使用会话控制器和服务之间传递数据。我送从记录，JS 按 requestCurrentUser 功能的请求象下面这样：

I have a record.js for RecordCtrl and I want use requestCurrentUser fnction that exist in sessionService.js. I use Session for pass data between controller and service. I send a request from record,js by requestCurrentUser function like below:

'use strict';
var app = angular.module('app');
app.controller('RecordCtrl',['$scope','Session','Records',function($scope, Session, Records){
    $scope.user = Session.requestCurrentUser();
}]);

和我收到这在 sessionService.js 象下面这样：

and I recieve this in sessionService.js like below:

  'use strict';
   angular.module('sessionService', [])
    .factory('Session', function($location, $http, $q) {
        var service = {

            requestCurrentUser: function() {
                    return $http.get('/api/users').then(function(response) {
                        service.currentUser = response.data.user;
                        return service.currentUser;
                    );
                }
            },
            currentUser: null,
        return service;
    });

我可以在 requestCurrentUser 正确地获取数据，但我不能接受她在 record.js 此数据。当我回响在 sessionService.js 的数据，我可以看到下面的数据：

I can get data correctly in requestCurrentUser, but I cannot recieve this data in record.js. When I echo data in sessionService.js, I can see below data:

Object {id: 2, email: "[e-mail]", created_at: "2014-08-11T08:37:59.981Z", updated_at: "2014-08-26T08:03:27.702Z"} 

但我不能接受她在 record.js 这个数据，我得到一个空的对象，象下面这样：

But I cannot recieve this data in record.js and I get an empty object like below:

[object Object] 

我觉得code的问题是关于会话我在2 JS 文件（使用 record.js 和 sessionService.js ）。对于添加的依赖，我有一个 app.js 包含在这个依赖。

I think the problem of code is about Session that I use in 2 js file(record.js and sessionService.js). For add dependency, I have a app.js that include dependencies on this.

app.js ：

'use strict';
angular.module('app',['ngRoute', 'ngResource', 'sessionService', 'recordService'])

我找不到这个问题，我想补充 sessionService.js 到 record.js 按低于code

app.service('sessionService');

但问题没有解决。我不知道我怎么能解决这个问题呢？任何一个有想法解决这个问题？

But the problem isn't fix. I don't know how can I resolve this problem? Any one have idea for fix this problem?

推荐答案

它可以固定如下：

'use strict';
var app = angular.module('app');
app.controller('RecordCtrl',['$scope','Session','Records',function($scope, Session, Records){
    Session.requestCurrentUser().then(function(data) {
        $scope.user = data;
    });

}]);
