如何在nodejs中将文件上传请求转发到其他域名？

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

// 创建一个HTTP服务器
const server = http.createServer((req, res) => {
  if (req.url === '/upload' && req.method === 'POST') {
    // 获取上传的文件数据
    const fileData = req.read();

    // 将文件数据转发到其他域名
    const options = {
      hostname: '其他域名',
      port: 80,
      path: '/upload',
      method: 'POST',
      headers: {
        'Content-Type': 'application/octet-stream',
        'Content-Length': fileData.length
      }
    };

    const request = http.request(options, (response) => {
      // 接收转发请求的响应数据
      let responseData = '';
      response.on('data', (chunk) => {
        responseData += chunk;
      });

      response.on('end', () => {
        // 将转发请求的响应数据返回给客户端
        res.end(responseData);
      });
    });

    // 将文件数据写入转发请求
    request.write(fileData);
    request.end();
  } else {
    res.statusCode = 404;
    res.end('Not Found');
  }
});

// 监听端口
server.listen(3000, () => {
  console.log('Server is running on port 3000');
});
