android - 在 ionic 应用程序中实现推送通知

Question

我正在尝试在适用于 Android 的 ionic 应用程序中实现推送通知。我已按照 http://docs.ionic.io/v1.0/docs/push-from-scratch 中的分步指南进行操作.当我在 Android 手机上运行我的应用程序时，注册用户会列在 apps.ionic.io 中。所以用户注册工作正常。但是设备注册不起作用。它给出了错误无法读取未定义的属性“pushNotification”

这是我在 app.js 顶部的代码

angular.module('starter', ['ionic','ngCordova',
    'ionic.service.core',
    'ionic.service.push',
    'starter.controllers',
    'starter.services'])

    .config(['$ionicAppProvider', function($ionicAppProvider) {
        // Identify app
        $ionicAppProvider.identify({
            // The App ID (from apps.ionic.io) for the server
            app_id: '',
            // The public API key all services will use for this app
            api_key: '',
            // Set the app to use development pushes
           // dev_push: true
            gcm_id: ''
        });
    }])

这是我的 Controller 中的代码

 .controller('DashboardCtrl', function($scope,$localstorage, WildfireService, CommonUtilityService,PushNotificationService,$ionicPopup, $ionicLoading) {      
      PushNotificationService.identifyUser();
      PushNotificationService.pushRegister();

    })

这是我的 services.js

 .service('PushNotificationService', function($q, $ionicUser, $ionicPush) {
        var PushNotificationService = this;
        PushNotificationService.identifyUser  = function(){
            var user = $ionicUser.get();
            if(!user.user_id) {
                // Set your user_id here, or generate a random one.
                user.user_id = $ionicUser.generateGUID();
            };

            // Add some metadata to your user object.
            angular.extend(user, {
                name: 'Technews',
                bio: 'Hardcoded for now'
            });

            // Identify your user with the Ionic User Service
            $ionicUser.identify(user).then(function(){
                //alert('Identified user ' + user.name + '\n ID ' + user.user_id);
                return true;
            });
        },

        PushNotificationService.pushRegister = function(){
            // Register with the Ionic Push service.  All parameters are optional.
            $ionicPush.register({
                canShowAlert: true, //Can pushes show an alert on your screen?
                canSetBadge: true, //Can pushes update app icon badges?
                canPlaySound: true, //Can notifications play a sound?
                canRunActionsOnWake: true, //Can run actions outside the app,
                onNotification: function(notification) {
                    // Handle new push notifications here
                    // console.log(notification);
                    alert(notification);
                    return true;
                }
            });
        }
    })

任何人都可以告诉我错误在哪里或我遗漏了什么吗？

我已经在 index.html 中添加了这些

<script src="lib/ionic/js/ionic.bundle.js"></script>
    <script src="lib/ngCordova/dist/ng-cordova.js"></script>
    <script src="lib/ionic-service-core/ionic-core.js"></script>
    <script src="lib/ionic-service-push/ionic-push.js"></script>

推送通知终于对我有用了。我将 pushRegister 的函数调用从 Controller 移到了 identifyUser 函数。所以这是我的新工作代码。 Controller 代码

.controller('DashboardCtrl', function($scope,$localstorage, WildfireService, CommonUtilityService,PushNotificationService,$ionicPopup, $ionicLoading) {      
      PushNotificationService.identifyUser();


    })

这是新的 services.js

 .service('PushNotificationService', function($q, $ionicUser, $ionicPush) {
            var PushNotificationService = this;
            PushNotificationService.identifyUser  = function(){
                var user = $ionicUser.get();
                if(!user.user_id) {
                    // Set your user_id here, or generate a random one.
                    user.user_id = $ionicUser.generateGUID();
                };

                // Add some metadata to your user object.
                angular.extend(user, {
                    name: 'Technews',
                    bio: 'Hardcoded for now'
                });

                // Identify your user with the Ionic User Service
                $ionicUser.identify(user).then(function(){
                    //alert('Identified user ' + user.name + '\n ID ' + user.user_id);
PushNotificationService.pushRegister();
                    return true;
                });
            },

            PushNotificationService.pushRegister = function(){
                // Register with the Ionic Push service.  All parameters are optional.
                $ionicPush.register({
                    canShowAlert: true, //Can pushes show an alert on your screen?
                    canSetBadge: true, //Can pushes update app icon badges?
                    canPlaySound: true, //Can notifications play a sound?
                    canRunActionsOnWake: true, //Can run actions outside the app,
                    onNotification: function(notification) {
                        // Handle new push notifications here
                        // console.log(notification);
                        alert(notification);
                        return true;
                    }
                });
            }
        })
