axios

btn3.onclick = function (){
       axios({
           method: "get",
           url: "http://127.0.0.1:3000/student",

       }).then((res) => {
           console.log(res);
           console.log(res.data);
       }).catch((err) => {
           console.log(err);
       })
   }

axios会自动设置请求头Application和对对返回做promise处理
