下载mp3而不是默认在浏览器中播放？

const express = require('express');
const app = express();

app.get('/download', (req, res) => {
  // 设置响应头，指定文件名为example.mp3
  res.setHeader('Content-Disposition', 'attachment; filename=example.mp3');
  // 设置响应内容的类型为audio/mpeg
  res.setHeader('Content-Type', 'audio/mpeg');

  // 读取mp3文件并发送给客户端
  const fs = require('fs');
  const fileStream = fs.createReadStream('path/to/example.mp3');
  fileStream.pipe(res);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
