preface

Today, we will develop a small effect for you. The length is short, mainly to show you the effect.

In actual combat

  1. First we initialize a Node project

    npm init -y
Copy the code

  2. Create an app.js file

    'use strict';

const nodemailer = require('nodemailer');

let transporter = nodemailer.createTransport({
  // host: 'smtp.ethereal.email',
  service: 'qq'./ / use the built-in email transmission check the support list: https://nodemailer.com/smtp/well-known/
  port: 465./ / SMTP port
  secureConnection: true.// SSL is used

    pass: 'kzudmlwerknibejc'.// SMTP authorization code}});let mailOptions = {
  from: '"xxx" <[email protected]>'.// sender
  to: '[email protected]'.// receivers
  subject: 'Hello'.// Subject line
  // Send text or HTML
  // text: 'Hello world? ', // plain text body
  html: 'Hello world? ' // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, (error, info) = > {
  if (error) {
    return console.log(error);
  }
  console.log('Message sent: %s', info.messageId);
  // Message sent: <[email protected]>
});
Copy the code
