使用Firebase功能將實時數據庫中的數據發送到電子郵件

Question

如何通過電子郵件將某些數據發送到Firebase Functions？ 假設有一個授權用戶，我們將其一些數據（例如出生日期）放入了實時數據庫。 如何使用Firebase Functions在HTTP請求后如何將此字段發送到電子郵件？

Answer 1

要通過JS發送電子郵件，您需要連接nodemailer

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');

並創建運輸：

let mailTransportAuth = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 587,
    secure: false,
    requireTLS: true,
    auth: {
        user: 'email',  /
        pass: 'password'
    }
});

然后創建一個函數來監視實時數據庫中的更改（onUpdate）並發送字母：

exports.sendCodeOnEmail = functions.database.ref('/users/{userssId}/').onUpdate((snapshot, context) => {
    var newCode = generateCode()
    var key = Object.keys(snapshot.after.val())[0];

    const c = snapshot.after.child(key).toJSON().toString();
    const email = snapshot.after.child("email").exportVal();
    const code = snapshot.after.child("code").exportVal();

        snapshot.after.ref.update({'code': newCode});
        const mailOptions = {
            from: '"From me" <noreply@firebase.com>',
            to: email,
            text: "text"
        };
        mailOptions.subject = "Subject message";
        console.log(snapshot);

        try {
            mailTransportAuth.sendMail(mailOptions);
            console.log(`Email sent to:`, email);
        } catch (error) {
            console.error('There was an error while sending the email:', error);
        }

    console.log("Send code on email: " + email, " , code: " + code);

    return null;
});
