一、nodeJshtml

let http = require('http');
let url = require('url');
let fs = require('fs');
let querystring=require('querystring');//操做參數模塊

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("收到請求.");
  response.writeHead(200,{"Content-Type":'text/plain','charset':'utf-8','Access-Control-Allow-Origin':'*','Access-Control-Allow-Methods':'PUT,POST,GET,DELETE,OPTIONS'});//能夠解決跨域的請求
  console.log(param);  //輸出  { name: '魯班大師', iq: '250' }
  //str=fs.readFileSync('json.txt');//讀取文件內容
  response.write(str);
  response.end();
}
http.createServer(onRequest).listen(8888);
