如何在nodejs中下载文件( http和https)并实时查看/显示下载进度？

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

// 下载文件的URL
const fileUrl = 'http://example.com/file.zip';

// 下载文件保存的路径
const filePath = './downloads/file.zip';

// 发送HTTP请求并下载文件
const downloadFile = (url, path) => {
  const protocol = url.startsWith('https') ? https : http;

  protocol.get(url, (response) => {
    const totalSize = parseInt(response.headers['content-length'], 10);
    let downloadedSize = 0;

    const fileStream = fs.createWriteStream(path);

    response.on('data', (chunk) => {
      downloadedSize += chunk.length;
      const progress = (downloadedSize / totalSize) * 100;
      console.log(`Downloaded ${progress.toFixed(2)}%`);

      fileStream.write(chunk);
    });

    response.on('end', () => {
      fileStream.end();
      console.log('File downloaded successfully');
    });
  });
};

// 调用下载函数
downloadFile(fileUrl, filePath);
