通过node.js搭建服务器 来处理post或者get请求

node.js读取数据

const http = require("http")

const url = require("url")

const queryString = require("querystring")

const server= http.createServer((req,res)=>{

    //req.url 请求的URL

    // GET QUERY params

    res.setHeader("Access-Control-Allow-Origin", "*");

    let methods = req.method;

    console.log("当前的访问方式是:"+ methods);

    if(methods == "GET"){

        let params = url.parse(req.url,true,true);

        console.log(params)

        //req.method

        console.log(req.method)

        res.setHeader("content-type","text/html;charset=UTF-8")

        res.end("hello server! 当前需要查询的id:"+params.query.id)

    }else {

        let datas = "";

        req.on("data",(chunk)=>{

            datas+=chunk;

            console.log(datas)

        })

        req.on("end",()=>{

                         如果是ajax post请求这里换成JSON.parse

            let postData= queryString.parse(datas.toString())

            console.log(postData)

        })

        res.setHeader("content-type","text/html;charset=UTF-8")

        res.end("当前请求方式为post")

    }

})

server.listen(3000,()=>{

    console.log("server is ready on port 3000")

})
