只有当PhoneGap应用程序在前台使用节点推送通知时，Android中的推送通知才能工作。

Question

在我的PhoneGap / Cordova应用程序(使用Framework7)中，我使用<plugin name="phonegap-plugin-push" source="npm" spec="2.3.0" />来启用推送通知。在项目文件夹的根目录中，我已经将google-services.json文件放入其中。当用户登录到我的应用程序时，设备令牌将在我的服务器上注册。接下来，我使用node-pushnotifications模块向这些令牌发送推送通知。

对于iOS设备，一切正常工作，但安卓只有在应用程序处于前台时才能工作。当我发送推送通知时，应用程序在后台，似乎什么都没有发生。当应用程序被打开(带回前台)时，会显示丢失的通知(更准确地说，弹出消息显示“新消息已经到达”，对于每个“遗漏”的推送通知，就像应用程序处于前景模式时的预期行为一样)。

我在StackOverflow上找到了几个相关的问题和答案，但它们并没有解决我的问题，但也许我在这些答案中遗漏了什么？例如，有人建议您需要指定一个message变量。但是，当我在服务器代码中包含这一点时，就会出现一个解析错误。另外，根据我阅读的node-pushnotifications模块的说明，这应该是不必要的。

更新1

当我使用Firebase控制台向Android设备发送推送消息时，一切正常工作(当应用程序处于后台时，将显示推送消息)。我怀疑原因在于node-pushnotifications模块。

到目前为止，我在模块设置中尝试了，我有：

1. 将icon设置为默认值；
2. 将sound设置为默认值；
3. 将ID设置为SenderID (导致失败->通知未发送)；H 222H 123Set phonegap到phonegap(导致失败->通知未发送)H 226G 227

更新2

当应用程序处于后台时(但当应用程序关闭时)，使用node-gcm模块正确地传递推送通知。

欢迎使用node-pushnotifications进行此工作的任何帮助。我很高兴在需要的时候给出更多的解释和细节。

应用程序中的代码

基于http://macdonst.github.io/push-workshop/提供的代码

请注意。对于SenderID，我使用在/by Firebase中生成的发送者id键。

var message = {
    // Application Constructor
    initialize: function() {
        this.bindEvents();
    },
    // Bind Event Listeners
    //
    // Bind any events that are required on startup. Common events are:
    // 'load', 'deviceready', 'offline', and 'online'.
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
        document.getElementById("toggleBtn").addEventListener('click', this.toggle, false);
    },
    // deviceready Event Handler
    //
    // The scope of 'this' is the event. In order to call the 'receivedEvent'
    // function, we must explicitly call 'app.receivedEvent(...);'
    onDeviceReady: function() {
      message.push = PushNotification.init({
           "android": {
             "senderID": "**********"
           },
           "ios": {
             "sound": true,
             "vibration": true,
             "badge": false
           },
           "windows": {}
       });

       message.push.on('registration', function(data) {
           var oldRegId = localStorage.getItem('registrationId');
           if (oldRegId !== data.registrationId) {
               // Save new registration ID
               localStorage.setItem('registrationId', data.registrationId);
               // Post registrationId to your app server as the value has changed
               var uname= window.localStorage.getItem('uname');
               var pwd= window.localStorage.getItem('pwd');
               var devicetoken=localStorage.getItem('registrationId');
               
               var dataString="uname="+uname+"&pwd="+pwd+"&devicetoken="+devicetoken+"&updateregistration=yes";
            
                $.ajax({
                    type:"POST",  
                    url:"******************", data: dataString,
                    crossDomain: true,
                    cache: false, 
                    success:function(data)  
                    {  
                    }  
                });  
   
           }
       });

       message.push.on('error', function(e) {
           console.log("push error = " + e.message);
       });

        message.push.on('notification', function(data) {
          console.log('notification event');
            
          app.dialog.alert("You have a new message", function () {
              
                        app.views.main.router.navigate('/messages/');

            });
        
        });
    }
};

message.initialize();

    },

};
const push = new PushNotifications(settings);

// Step 2 create the notification
const data = {
    title: 'New push notification', // REQUIRED for Android
    topic: '**********', // REQUIRED for iOS (apn and gcm)
    /* The topic of the notification. When using token-based authentication, specify the bundle ID of the app.

--这是我实现的解决方案(目前正在安卓10和iOS 13.6上运行和测试)

它可以帮助您轻松显示定制推送通知的背景，前景，何时使用，当手机被锁定。

My配置在CLI:中

android 8.0.0

ios 4.5.5

cordova plugins

我正在使用的JS应用程序代码

document.addEventListener("deviceready", registrarDevice, false);

function registrarDevice() {
    try {
        var push = PushNotification.init({
            android: {
                senderID: "YOUR_SENDER_ID_FROM_FIREBASE"
            },
            browser: {
                pushServiceURL: 'http://push.api.phonegap.com/v1/push'

                sound: "true"
            },
            windows: {}

        push.on('registration', function (data) {
            // data.registrationId
