node_url模块_querystring模块

//引入模块
let http = require('http')
let fs = require('fs')
//引入url模块
let url = require('url')
// 引入querystring模块
let querystring = require('querystring')

let server = http.createServer((req, res)=>{
  //将url地址解析成url对象
  //pathname：返回url地址
  //query：返回参数字符串(从?后面开始截取字符串)
  let urlObj = url.parse(req.url)
  console.log('urlObj',urlObj)

  //将query参数解析成obj对象
  //count=1&name=jack&age=18 ==> {count: '1',name: 'jack', age:'18'}
  let querystringObj = querystring.parse(urlObj.query)
  // 等同于letlet querystringObj = querystring.decode(urlObj.query)
  console.log('querystringObj',querystringObj)
  // 反解析，将对象解析成字符串
  let parmsString = querystring.stringify(querystringObj)
  // 等同于let parmsString = querystring.encode(querystringObj)
  console.log('parmsString',parmsString)
  //数据接口监听
  if (urlObj.pathname == '/interface') {res.end("{name: 'jack', age: 18, job: 'web'}")}

      if (err) return err
      else res.end(data)
    })
