如何在nodejs上下载大量文件

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

const fileUrls = [
  'http://example.com/file1.txt',
  'http://example.com/file2.txt',
  'http://example.com/file3.txt'
];

function downloadFile(url, destination) {
  return new Promise((resolve, reject) => {
    const file = fs.createWriteStream(destination);

    http.get(url, (response) => {
      response.pipe(file);
      file.on('finish', () => {
        file.close(resolve);
      });
    }).on('error', (error) => {
      fs.unlink(destination, () => {
        reject(error);
      });
    });
  });
}

async function downloadFiles(urls) {
  for (const url of urls) {
    const fileName = url.split('/').pop();
    await downloadFile(url, fileName);
    console.log(`File ${fileName} downloaded.`);
  }
}

downloadFiles(fileUrls)
  .then(() => {
    console.log('All files downloaded successfully.');
  })
  .catch((error) => {
    console.error('Error downloading files:', error);
  });
