我试过部署一个firebase函数，但由于ESLint的一些问题，它总是失败。我也试过在谷歌上搜索答案，但我看到的一切对我来说都是希腊语。
我也偶然发现了this和this的答案，但它们似乎不适用于我的场景。

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
// exports.helloWorld = functions.https.onRequest((request, response) => {
//  response.send("Hello from Firebase!");
// });

//import firebase functions modules
const functions = require("firebase-functions");
//import admin module
const admin = require("firebase-admin");
admin.initializeApp(functions.config().firebase);

// Listens for new messages added to messages/:pushId
exports.pushNotification = functions.database.ref("/Message").onWrite( event => {
    //  Grab the current value of what was written to the Realtime Database.
    var valueObject = event.data.val();
    // Log the event
    console.log("Push notification event triggered for " + valueObject.title);

    //if(valueObject.title != null) {
      //valueObject.photoUrl= "Sent you a photo!";
   // }

  // Create a notification
    const payload = {
        data: {
            body:valueObject.body,
            imgUrl: valueObject.imgUrl,
            postUrl: valueObject.postUrl,
            title: valueObject.title
        },
    };

  //Create an options object that contains the time to live for the notification and the priority
    const options = {
        priority: "high",
        timeToLive: 60 * 60 * 24
    };

    return admin.messaging().sendToTopic("Posts", payload, options);
});
