Question

我已经看到很多人问这个问题，我已经尝试了答案，我的有效负载中没有所谓的“通知”。

当页面处于前台时，将完全按预期接收消息。

客户代码：

var config = {
  apiKey: "<API_KEY>",
  authDomain: "AUTH_DOMAIN",
  databaseURL: "DATABASE",
  projectId: "PROJECT_ID",
  storageBucket: "STORAGE_BUCKET",
  messagingSenderId: "SENDER_ID"
};

firebase.initializeApp(config);

const messaging = firebase.messaging()

messaging.requestPermission()
.then(() => {
  console.log('Permission granted')
  return messaging.getToken()
})
.then((token) => {
  console.log(token)
})
.catch(() => {
  console.log('Permission denied')
})

messaging.onMessage((payload)=>{
  console.log("message: ", payload)
  // TODO: handle message
})

服务人员代码（与客户端相同的配置）

const messaging = firebase.messaging();
messaging.setBackgroundMessageHandler(function (payload) {
  console.log('Handling background message ', payload);
  return self.registration.showNotification(payload.data.title, {
    body: payload.data.body,
  });
});

服务器代码：

var express = require('express');
var router = express.Router();
var firebase = require('firebase');
var admin = require('firebase-admin');
var serviceAccount = require('./../../../web-quickstart-e2909-1896918629ac.json')

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: '<DB_URL>'
});

const registrationToken = <REGISTRATION_TOKEN>

var message = {
  data: {
    body: "Hello world!",
    title: "Hi",
    // icon: "<ICON_SOURCE>" 
  },
  token: registrationToken
};

const sendMessage = () => {
  admin.messaging().send(message)
  .then((response) => {
    // Response is a message ID string.
    console.log('Successfully sent message:', response);
  })
  .catch((error) => {
    console.log('Error sending message:', error);
  });
}

sendMessage()

/* GET home page. */
router.get('/', function(req, res, next) {
  sendMessage()
  res.json({ title: 'Express' });
});

module.exports = router;

在服务器代码中，我确实获得了一条日志，指出该消息已成功发送，但是客户端未收到任何消息，日志insetBackgroundMessageHandler从未被记录。

Firebase setBackgroundMessageHandler没有被调用
