nodejs实现的简单web服务器功能示例

<script src="/UploadFiles/2021-04-02/jquery-1.12.1.js">

nodejs代码：


var http = require('http');
var url = require('url');
var qs = require('querystring');
http.createServer(function(req,res){
  res.writeHead(200,{'Content-Type':'text/plain;charset=UTF-8','Access-Control-Allow-origin':'*'});
  if(req.method.toUpperCase() == 'GET'){
    var query = url.parse(req.url, true).query;// 接受的数据
    res.end(JSON.stringify(query));
  }else if(req.method.toUpperCase() == 'POST'){
    var postData = '';
    req.on('data',function(data){
      postData += data; //接受的数据
    });
    req.on('end',function(){
      var query = qs.parse(postData);
      res.end(JSON.stringify(query));//返回的数据
    });
  }
}).listen('3000',function(){
  console.log('this is callback');
});
console.log('server is running');
