如何从http请求运行节点localhost子进程？

const http = require('http');
const { exec } = require('child_process');

const server = http.createServer((req, res) => {
  // 检查请求路径和方法
  if (req.url === '/runcmd' && req.method === 'POST') {
    // 从请求中读取命令
    let command = '';
    req.on('data', (chunk) => {
      command += chunk;
    });

    req.on('end', () => {
      // 执行子进程命令
      exec(command, (error, stdout, stderr) => {
        if (error) {
          res.statusCode = 500;
          res.end(`Command execution failed: ${error.message}`);
        } else {
          res.end(stdout);
        }
      });
    });
  } else {
    res.statusCode = 404;
    res.end('Not Found');
  }
});

server.listen(3000, 'localhost', () => {
  console.log('Server running at http://localhost:3000/');
});
