我正在制作一个离子3应用程序。我希望即使应用在前景时也会出现通知。我尝试使用FCM插件,仅在应用程序在后台时才收到通知。
home.ts
import { AngularFireDatabase } from 'angularfire2/database';
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import firebase from 'firebase';
declare var FCMPlugin;
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
firestore = firebase.database().ref('/pushtokens');
firemsg = firebase.database().ref('/messages');
constructor(public navCtrl: NavController,public afd:AngularFireDatabase) {
this.tokensetup().then((token)=>{
this.storeToken(token);
})
}
ionViewDidLoad() {
FCMPlugin.onNotification(function (data) {
if (data.wasTapped) {
//Notification was received on device tray and tapped by the user.
alert(JSON.stringify(data));
} else {
//Notification was received in foreground. Maybe the user needs to be notified.
alert(JSON.stringify(data));
}
});
FCMPlugin.onTokenRefresh(function (token) {
alert(token);
});
}
tokensetup(){
var promise = new Promise((resolve,reject)=>{
FCMPlugin.getToken(function(token){
resolve(token);
},(err)=>{
reject(err);
});
})
return promise;
}
storeToken(token){
this.afd.list(this.firestore).push({
uid: firebase.auth().currentUser.uid,
devtoken: token
}).then(()=>{
alert('Token stored')
}).catch(()=>{
alert('Token not stored');
})
// this.afd.list(this.firemsg).push({
// sendername:'adirzoari',
// message: 'hello for checking'
// }).then(()=>{
// alert('Message stored');
// }).catch(()=>{
// alert('message not stored');
// })
}
}
通知的功能云
var functions = require('firebase-functions');
var admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var wrotedata;
exports.Pushtrigger = functions.database.ref('/messages/{messageId}').onWrite((event) => {
wrotedata = event.data.val();
admin.database().ref('/pushtokens').orderByChild('uid').once('value').then((alltokens) => {
var rawtokens = alltokens.val();
var tokens = [];
processtokens(rawtokens).then((processedtokens) => {
for (var token of processedtokens) {
tokens.push(token.devtoken);
}
var payload = {
"notification":{
"title":"From" + wrotedata.sendername,
"body":"Msg" + wrotedata.message,
"sound":"default",
},
"data":{
"sendername":wrotedata.sendername,
"message":wrotedata.message
}
}
return admin.messaging().sendToDevice(tokens, payload).then((response) => {
console.log('Pushed notifications');
}).catch((err) => {
console.log(err);
})
})
})
})
function processtokens(rawtokens) {
var promise = new Promise((resolve, reject) => {
var processedtokens = []
for (var token in rawtokens) {
processedtokens.push(rawtokens[token]);
}
resolve(processedtokens);
})
return promise;
}
仅在后台应用程序时起作用。但是,当我从应用程序退出时,它不在后台时,我没有收到任何通知。
您需要编辑FCM插件文件。我现在只为Android找到了解决方案。
我使用https://github.com/fechanique/cordova-plugin-fcm此FCM插件,用于Cordova的Android和iOS。
您需要编辑文件myfirebasemessagingservice.java Line 53(行否可能有所不同)。
在此文件中,该方法的末尾有一个方法onMessageReceived
,有一行评论,该行调用另一种方法,即sendNotification(....)
。
sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody(), data);
您必须从 remoteMessage.getData() to data
中取消注释并更改最后一个参数(代码中已经存在数据变量)。
并评论此行FCMPlugin.sendPushPayload( data );
现在你很好。现在,即使打开应用程序(前景),您也可以收到通知,您将收到横幅(浮动)通知。
如果您找到了iOS的任何东西,请让我知道!
我正在为离子3使用firebase插件。检查是否包含"通知数据"是否包含" Notification_foreground",并将其保存在可变的前景notification中。
if(data.containsKey("notification_foreground")){
foregroundNotification = true;
}
然后,它创建 showTification 变量,该变量决定我们是否需要显示通知并将其传递给sendmessage(显示通知功能)。
if (!TextUtils.isEmpty(body) || !TextUtils.isEmpty(title) || (data != null && !data.isEmpty())) {
boolean showNotification = (FirebasePlugin.inBackground() || !FirebasePlugin.hasNotificationsCallback() || foregroundNotification) && (!TextUtils.isEmpty(body) || !TextUtils.isEmpty(title));
sendMessage(data, messageType, id, title, body, showNotification, sound, vibrate, light, color, icon, channelId, priority, visibility);
}
您的有效载荷应包含Notification_foreground,Notification_Title和Notification_body。
