注册接口：
/register

else if(req.url == "/register" && req.method == "POST"){let str = ''; req.on('data',(chunk)=>{str += chunk; })req.on('end',()=>{let dataObj = querystring.parse(str); fs.readFile("./data.json","utf8",(err,data)=>{let obj = JSON.parse(data); for(let i = 0; i < obj.length; i++){if(obj[i].username == dataObj.username){return res.end('3'); }}obj.push(dataObj); fs.writeFile('./data.json',JSON.stringify(obj),'utf8',(err,result)=>{if(err){return res.end('2'); }return res.end('1'); })})})}

登录接口：
/login

else if(dataurl.pathname == "/login" && req.method == "GET"){console.log(dataurl); var userInput = querystring.parse(dataurl.query); fs.readFile("./data.json","utf8",(err,data)=>{let obj = JSON.parse(data); for(let i = 0; i < obj.length; i++){if(obj[i].username == userInput.username && obj[i].password == userInput.password){return res.end('1'); }else if(obj[i].username == userInput.username && obj[i].password != userInput.password){return res.end('3'); }}})}
