Node.js GET/POST请求的使用小结

const http = require('http');

const server = http.createServer((req, res) => {
  if (req.method === 'GET') {
    // 处理GET请求
    const url = req.url;
    const query = require('url').parse(url, true).query;

    // 响应数据
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end(`GET请求，URL: ${url}，Query: ${JSON.stringify(query)}`);
  } else {
    // 处理其他请求
    res.writeHead(404, { 'Content-Type': 'text/plain' });
    res.end('404 Not Found');
  }
});

server.listen(3000, () => {
  console.log('服务器运行在http://localhost:3000');
});

const http = require('http');
const { StringDecoder } = require('string_decoder');

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    // 处理POST请求
    const decoder = new StringDecoder('utf-8');
    let body = '';

    req.on('data', (chunk) => {
      body += decoder.write(chunk);
    });

    req.on('end', () => {
      body += decoder.end();

      // 响应数据
      res.writeHead(200, { 'Content-Type': 'text/plain' });
      res.end(`POST请求，Body: ${body}`);
    });
  } else {
    // 处理其他请求
    res.writeHead(404, { 'Content-Type': 'text/plain' });
    res.end('404 Not Found');
  }
});

server.listen(3000, () => {
  console.log('服务器运行在http://localhost:3000');
});
