在nodejs中从post请求发送数据到get请求

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

const server = http.createServer((req, res) => {
  // 处理请求
});

const port = 3000;
server.listen(port, () => {
  console.log(`Server running on port ${port}`);
});

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    // 处理POST请求
  } else if (req.method === 'GET') {
    // 处理GET请求
  }
});

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let postData = '';

    req.on('data', chunk => {
      postData += chunk;
    });

    req.on('end', () => {
      // 处理完整的POST数据
      const parsedData = querystring.parse(postData);
      // 继续处理GET请求
      handleGetRequest(parsedData, res);
    });
  } else if (req.method === 'GET') {
    // 处理GET请求
  }
});

function handleGetRequest(data, res) {
  const query = querystring.stringify(data);
  const url = `http://example.com/?${query}`;

  http.get(url, getRes => {
    let getResult = '';

    getRes.on('data', chunk => {
      getResult += chunk;
    });

    getRes.on('end', () => {
      // 处理GET请求的结果
      res.writeHead(200, { 'Content-Type': 'text/plain' });
      res.end(getResult);
    });
  });
}
