nodejs获取和返回数据
1、nodeJs
let http = require('http'); let url = require('url'); let fs = require('fs'); let querystring=require('querystring');//操作参数模块 let str='{"id":"1",name:"zhangSan",age:30,sex:"men"}'; function onRequest(request, response){ let urlStr = url.parse(request.url); let param=querystring.parse(urlStr.query); console.log("收到请求."); response.writeHead(200,{"Content-Type":'text/plain','charset':'utf-8','Access-Control-Allow-Origin':'*','Access-Control-Allow-Methods':'PUT,POST,GET,DELETE,OPTIONS'});//可以解决跨域的请求 console.log(param); //输出 { name: '鲁班大师', iq: '250' } //str=fs.readFileSync('json.txt');//读取文件内容 response.write(str); response.end(); } http.createServer(onRequest).listen(8888);
