如何在节点js中附加带有电子邮件的.ics文件？

const fs = require('fs');

const icsData = `BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//My Calendar//EN
BEGIN:VEVENT
UID:1234567890
DTSTAMP:20220101T000000Z
DTSTART:20220101T090000Z
DTEND:20220101T100000Z
SUMMARY:Meeting
DESCRIPTION:This is a meeting invitation.
LOCATION:Office
END:VEVENT
END:VCALENDAR`;

fs.writeFileSync('event.ics', icsData);

npm install nodemailer

const nodemailer = require('nodemailer');

// 创建一个SMTP传输对象
const transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false,
  auth: {
    user: 'your-email@example.com',
    pass: 'your-password'
  }
});

// 邮件选项
const mailOptions = {
  from: 'your-email@example.com',
  to: 'recipient@example.com',
  subject: 'Meeting Invitation',
  text: 'Please see the attached calendar event.',
  attachments: [
    {
      filename: 'event.ics',
      path: './event.ics',
      contentType: 'text/calendar'
    }
  ]
};

// 发送邮件
transporter.sendMail(mailOptions, (error, info) => {
  if (error) {
    console.log('Error:', error);
  } else {
    console.log('Email sent:', info.response);
  }
});
