首先需要安装一下nodemailer
#nmp nodemailer install --save
然后就参照官方文档的例程改写一下就行了，代码如下：
‘use strict‘;const nodemailer = require(‘nodemailer‘);// Generate test SMTP service account from ethereal.email// Only needed if you don‘t have a real mail account for testingnodemailer.createTestAccount((err, account) => { ???// create reusable transporter object using the default SMTP transport ???let transporter = nodemailer.createTransport({ ???????host: ‘smtp.163.com‘, ???????port: 465, ???????secure: true, // true for 465, false for other ports ???????auth: { ???????????user: ‘abc@163.com‘, // generated ethereal user ???????????pass: ‘PASSWORD‘ // generated ethereal password ???????} ???}); ???// setup email data with unicode symbols ???let mailOptions = { ???????from: ‘abc@163.com‘, // sender address ???????to: ‘abc@163.com,def@163.com‘, // list of receivers ???????subject: ‘标题：这是一封来自Nodejs发送的邮件‘, // Subject line ???????text: ‘你好吗?‘, // plain text body ???????html: ‘<b>北京欢迎你</b>‘ // 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); ???????// Preview only available when sending through an Ethereal account ???????console.log(‘Preview URL: %s‘, nodemailer.getTestMessageUrl(info)); ???????// Message sent: <b658f8ca-6296-ccf4-8306-87d57a0b4321@example.com> ???????// Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou... ???});});赘述一下：nodemailer的官网在 https://nodemailer.com/about/ ，一般看原文比网文靠谱。
