【中文标题】Android 中的推送通知仅在 PhoneGap 应用程序在前台使用 node-pushnotifications 时有效【英文标题】：Push notifications in Android only work when PhoneGap app is in foreground using node-pushnotifications 【发布时间】：2020-11-18 18:30:52 【问题描述】：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，我放置了google-services.json 文件。当用户登录我的应用程序时，设备令牌会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，一切都按预期运行，但对于 android，它仅在应用处于前台时才有效。当我在应用程序处于后台时发送推送通知时，似乎什么都没有发生。当应用程序打开（回到前台）时，显示已错过的通知（更准确地说，弹出消息显示“新消息已到达”，对于每个“错过”的推送通知，这是预期的行为当应用程序处于前台模式时）。
我在 *** 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一些东西？例如，有人建议您需要指定一个message 变量。但是当我将它包含在服务器代码中时，会发生解析错误。另外，根据我对node-pushnotifications 模块说明的阅读，这应该没有必要。
===
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（当应用处于后台时，推送消息会显示）。我怀疑原因在于node-pushnotifications 模块。
到目前为止我所尝试的
在node-pushnotifications 模块设置中，我有：
-
将
icon设置为默认值；
将sound设置为默认值；
将ID设置为SenderID（导致失败-->通知未发送）；
将phonegap 设置为false（导致失败 --> 未发送通知）
===
更新 2
当应用程序处于后台时（但不是在应用程序关闭时），使用 node-gcm 模块正确传递推送通知。
===
欢迎任何帮助使用node-pushnotifications 完成这项工作。我很乐意在需要时提供更多解释和细节。
应用中的代码
基于http://macdonst.github.io/push-workshop/提供的代码
注意。对于SenderID，我使用了 Firebase 中/由 Firebase 生成的发件人 ID 密钥。
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();
服务器上的代码
基于https://github.com/appfeel/node-pushnotifications提供的代码
注意。对于gcm id，我使用了由 Firebase 生成的服务器密钥。
// Step 1: configure push notification settings
var PushNotifications = require('node-pushnotifications')
const settings =
gcm:
id: '*******',
phonegap: true, // phonegap compatibility mode, see below (defaults to false)
,
apn:
token:
key: '*******', // optionally: fs.readFileSync('./certs/key.p8')
keyId: '*******',
teamId: '*******',
,
production: true // true for APN production environment, false for APN sandbox environment,
//...
,
isAlwaysUseFCM: false, // true all messages will be sent through node-gcm (which actually uses FCM)
;
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.
* When using certificate-based authentication, the topic is usually your app's bundle ID.
* More details can be found under https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/sending_notification_requests_to_apns
*/

【问题讨论】：
【参考方案1】：这是我实施的解决方案（目前在 Android 10 和 iOS 13.6 上运行和测试）
它可以帮助您轻松地在后台、前台、使用时、手机锁定时显示自定义推送通知。
我在 CLI 中的配置：
cordova -v
7.1.0
cordova platforms
安卓 8.0.0
iOS 4.5.5
cordova plugins
phonegap-plugin-push 2.3.0 "PushPlugin"
phonegap-plugin-multidex 1.0.0 "Multidex"
我正在使用的 JS 应用代码
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'
,
ios:
alert: "true",
badge: "true",
sound: "true"
,
windows:
);
push.on('registration', function (data)
// data.registrationId
console.log(data);
);
push.on('notification', function (data)
console.log(data);
// data.message,
// data.title,
// data.count,
// data.sound,
// data.image,
// data.additionalData
);
push.on('error', function (e)
// e.message
console.log(e);
);
catch (err)
console.log("Error registrarDevice: ", err.message);
我服务器上的 PHP 代码

$url = 'https://fcm.googleapis.com/fcm/send';
if($device_type == "Android")
$fields = array(
'to' => $registatoin_ids,
'data' => $notification
);
else
$fields = array(

// Your Firebase Server API Key
$apikey = "YOUR_FIREBASE_SERVER_API_KEY";
$headers = array('Authorization:key='.$apikey,'Content-Type:application/json');

$fcm = new FCM();
$retresult = $fcm->send_push_notification($xdevice_destino, $NotificationArray, "Android");
return $retresult;

echo "<br>".notificaciones_android_base("YOUR_DEVICE_ID","NotificationTitle2021",$info_test);
【讨论】：
谢谢！该应用程序目前正在生产中，我会在一段时间内尝试您的解决方案（然后删除此评论）。 不客气。您目前正在使用 iOS 推送通知吗？以上是关于Android 中的推送通知仅在 PhoneGap 应用程序在前台使用 node-pushnotifications 时有效的主要内容，如果未能解决你的问题，请参考以下文章
当我的应用程序打开时，我需要推送通知显示，如 Android 中的 whatsapp、Viber（Phonegap）
