## 今天我們要使用Firebase functions  推送 FCM 給昨天我們寫好的 APP 

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

/////is ok
exports.helloFCM = functions.region('asia-northeast1').https.onRequest(async (request, response) => {
  console.log('A new user signed in for the first time.');
  const fullName = 'Anonymous';
  const Ipad_token = "cTBvQaDOt1A:APAXXXXXXXX5U6K1zhNfw4FkKJ";

  var registrationToken = 'YOUR_REGISTRATION_TOKEN';
  var topic = 'highScores';
  var message = {
    data: {
      score: '850',
      time: '2:45'
    },
    notification: {
      title: "FCM D 加辣",
      body: "FCM D 加辣",
    },

    token: Ipad_token
  };
  

  await admin.messaging().send(message).then((response) => {
    console.log('Successfully sent message:', response);
    return null;

  })
   admin.messaging().send(message).then((response) => {
    console.log('Successfully sent message:', response);
    return null;

  })
    .catch((error) => {
      console.log('Error sending message:', error);
    });
