const nodemailer = require("nodemailer");

// 要使用await，必须在async函数中
async function main() {
  // 创建传输对象
  let transporter = nodemailer.createTransport({
	//填服务器主机
    host: "smtp.126.com",
    port: 25,
    secure: false, // true for 465, false for other ports
    auth: {
      user: 'nodemailer2022@126.com', // 邮箱账号
      pass: 'xxx', // 授权密码
    },
  });

  // 定义传输信息
  let info = await transporter.sendMail({
    from: 'nodemailer2022@126.com', // 发送邮件地址
    to: "bar@example.com, baz@example.com", // 接受邮箱列表
    subject: "Hello ✔", // 邮件主题
    text: "Hello world?", // 内容
    html: "<b>Hello world?</b>", // html内容
  });

  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...
