Firebase Functions - FCM Push Message

Firebase 서비스 계정

: node.js 에서 FCM Push 를 보내기 위해서 필요한 계정

 

index.js

const functions = require("firebase-functions");
const admin = require("firebase-admin");

const express = require("express");
const cors = require("cors");

const app = express();

app.use(cors({ origin: true }));
app.use(require("./routes/sendmessage.routes"));
exports.app = functions.https.onRequest(app);

/**
router 사용하지 않고 index.js 에서 바로 구현 시
exports.sendPushMessage = functions.https.onRequest(async (req, res) => {
    const registrationTokens = 'Firebase Token';

    const message = {
        notification: {
            title : "제목 : 메세징 테스트",
            body : "내용 : 11:14"
        },
        token: registrationTokens
    };

    admin.messaging().send(message)
        .then((response) => {
            console.log('Successfully sent message: : ', response)
        }).catch(function (err) {
            console.log('Error Sending message!!! : ', err)
