Node.js基本数据处理

const http = require('http');
const querystring = require('querystring');//将name=test&id=5解析为{name:test,id:5}
const server = http.createServer((req,res)=>{
   let [url,query] = req.url.split('?')
   let get = querystring.parse(query);
   console.log(get.name)//test
   res.end('hello')

})
server.listen(8080,()=>{
    console.info('server start')
})

const http = require('http');
const querystring = require('querystring');
const url = require('url')
const server = http.createServer((req,res)=>{
   let {query} =url.parse(req.url,true)//节气query
   console.log(query) //{name:test,id:5}
   res.end('hello')

})
server.listen(8080,()=>{
    console.info('server start')
})

const http = require('http')
const querystring = require('querystring')
const url = require('url')
const server = http.createServer((req,res)=>{
    let arr = [];
        //有数据过来时(二进制)
    req.on('data',buffer=>{
        //拼接数据
        arr.push(buffer)
    });
    req.on('end',()=>{
        //数据接收完成连接buffer
        let buffer = Buffer.concat(arr)
        let post = querystring.parse(buffer.toString())
        console.log(post)//{name:test}
        
    });//数据结束

   res.end('hello')

})
server.listen(8080,()=>{
    console.info('server start')
})
