如何使用node_mailer发送gzip文件

npm install nodemailer zlib

const nodemailer = require('nodemailer');
const zlib = require('zlib');

const transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false,
  auth: {
    user: 'your_email@example.com',
    pass: 'your_password'
  }
});

function sendGzipFile() {
  const filePath = '/path/to/your/file.txt'; // 替换为你的文件路径
  const gzipFilePath = '/path/to/your/file.txt.gz'; // 替换为你的压缩文件路径

  // 使用zlib模块进行gzip压缩
  const gzip = zlib.createGzip();
  const input = fs.createReadStream(filePath);
  const output = fs.createWriteStream(gzipFilePath);

  input.pipe(gzip).pipe(output);

  // 添加压缩后的文件作为附件
  const attachment = {
    filename: 'file.txt.gz',
    path: gzipFilePath
  };

  // 邮件选项
  const mailOptions = {
    from: 'your_email@example.com',
    to: 'recipient@example.com',
    subject: 'Sending a Gzip File',
    text: 'Please find the attached gzip file.',
    attachments: [attachment]
  };

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

sendGzipFile();
