我如何解压一个文件并在Node.js中发送它作为响应？

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

const readStream = fs.createReadStream('path/to/compressed/file');

const writeStream = fs.createWriteStream('path/to/uncompressed/file');

const unzip = zlib.createGunzip();
readStream.pipe(unzip).pipe(writeStream);

response.setHeader('Content-Type', 'application/octet-stream');
response.setHeader('Content-Disposition', 'attachment; filename=uncompressed_file');
writeStream.pipe(response);

const http = require('http');
const fs = require('fs');
const zlib = require('zlib');

http.createServer((request, response) => {
  const readStream = fs.createReadStream('path/to/compressed/file');
  const writeStream = fs.createWriteStream('path/to/uncompressed/file');
  const unzip = zlib.createGunzip();

  response.setHeader('Content-Type', 'application/octet-stream');
  response.setHeader('Content-Disposition', 'attachment; filename=uncompressed_file');

  readStream.pipe(unzip).pipe(writeStream).pipe(response);
}).listen(3000);
