如何使用Node JS发送邮件

Question

我试图在nodemailer中使用node js发送邮件。但是我不确定如何不使用auth来使用node js发送邮件。

mail.js

const nodemailer = require('nodemailer');
const ejs = require('ejs');
const fs = require('fs');

let transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true,
    auth: {
        user: 'xxx@gmail.com',
        pass: 'xxx'
    }
});

let mailOptions = {
    from: '"xxx" <xxx@gmail.com>',
    to: 'yyy@gmail.com',
    subject: 'Teste Templete ✔',
    html: ejs.render( fs.readFileSync('e-mail.ejs', 'utf-8') , {mensagem: 'olá, funciona'})
};

transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
        return console.log(error);
    }
    console.log('Message %s sent: %s', info.messageId, info.response);
});
