如何在节点js中逐个下载文件？

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

function downloadFile(url, destination) {
  return new Promise((resolve, reject) => {
    const file = fs.createWriteStream(destination);
    https.get(url, (response) => {
      response.pipe(file);
      file.on('finish', () => {
        file.close();
        resolve();
      });
    }).on('error', (error) => {
      fs.unlink(destination);
      reject(error);
    });
  });
}

async function downloadFiles(urls, destinationFolder) {
  for (let i = 0; i < urls.length; i++) {
    const url = urls[i];
    const filename = `file${i}.txt`;
    const destination = `${destinationFolder}/${filename}`;
    try {
      await downloadFile(url, destination);
      console.log(`File ${filename} downloaded successfully.`);
    } catch (error) {
      console.error(`Error downloading file ${filename}: ${error}`);
    }
  }
}

const urls = [
  'https://example.com/file1.txt',
  'https://example.com/file2.txt',
  'https://example.com/file3.txt'
];
const destinationFolder = './downloads';

downloadFiles(urls, destinationFolder);
