nodejs基于nodemailer插件实现发送邮箱

官网地址：https://nodemailer.com/about/

项目中添加插件nodemailer:

npm install nodemailer

发送邮件例子：

"use strict";
const nodemailer = require("nodemailer");

// async..await is not allowed in global scope, must use a wrapper
async function main() {
  // Generate test SMTP service account from ethereal.email
  // Only needed if you don't have a real mail account for testing
  let testAccount = await nodemailer.createTestAccount();

  // create reusable transporter object using the default SMTP transport
  // // 创建发送邮件的对象
  let transporter = nodemailer.createTransport({
    host: "smtp.qq.com",
    port: 456,
    secure: true, // true for 465, false for other ports
    auth: {
      user: '你的邮箱', // generated ethereal user 发送方QQ邮箱
      pass: '你的  mtp 验证码', // generated ethereal password
    },
  });

  // send mail with defined transport object
  let info = await transporter.sendMail({
    from: '"Fred Foo 👻" <foo@example.com>', // sender address
    to: "bar@example.com, baz@example.com", // list of receivers
    subject: "Hello ✔", // Subject line
    text: "Hello world?", // plain text body
    html: "<b>Hello world?</b>", // html body
  });

  console.log("Message sent: %s", info.messageId);
  // Message sent: <b658f8ca-6296-ccf4-8306-87d57a0b4321@example.com>

  // Preview only available when sending through an Ethereal account
  console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));
  // Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou...
}

main().catch(console.error);

注解：

1. 上面的 mtp 验证码，（以qq邮箱为例）在 “设置”》“账户”》 里面找
   

2.其它邮箱 host 在 services.json
相对路径：\node_modules\nodemailer\lib\well-known\services.json
截图一些：

3.报错 “no function … ”
有没有安装 node.js, nodemail

4.在运行文件时报Error: self signed certificate in certificate chain 错误

解决办法，运行时候先把本电脑的防护先关了（防火墙，360，金山毒霸等）
