如何通过node.js获取POST参数

const http = require('http');

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

if (req.method === 'POST') {
  // 处理POST请求
}

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

req.on('end', () => {
  // POST参数获取完成，进行处理
});

const querystring = require('querystring');

const params = querystring.parse(postData);

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

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

    req.on('end', () => {
      const params = querystring.parse(postData);
      // 根据需要进行处理
      console.log(params);
      res.end('POST参数获取成功');
    });
  } else {
    res.end('只支持POST请求');
  }
});

server.listen(3000, () => {
  console.log('服务器已启动，监听端口3000');
});
