使用节点js从其他链接呈现js文件

const http = require('http');

const server = http.createServer((req, res) => {
  // 处理请求和响应
});
const port = 3000; // 选择一个可用的端口号
server.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

const targetUrl = 'http://example.com/path/to/js/file.js'; // 替换为目标链接
http.get(targetUrl, (response) => {
  let data = '';
  response.on('data', (chunk) => {
    data += chunk;
  });
  response.on('end', () => {
    // 处理获取到的JavaScript文件数据
  });
}).on('error', (error) => {
  console.error(`Error: ${error.message}`);
});

// 保存到本地文件
const fs = require('fs');
const localFilePath = '/path/to/save/file.js'; // 替换为本地文件路径
fs.writeFile(localFilePath, data, (error) => {
  if (error) {
    console.error(`Error: ${error.message}`);
  } else {
    console.log('JavaScript file saved successfully');
  }
});

// 直接在服务器上呈现
res.setHeader('Content-Type', 'application/javascript');
res.end(data);
