Ajax uses Token to verify identity

success:function(dat){
          console.log(dat);
            if(dat.code==1){
              sessionStorage.setItem('token',dat.data.access_token);
              //这里设置缓存存储Token
              sessionStorage.setItem('user',userName);
              location.href = "index.html";
            }else{
              $(".tip2").html("用户名或密码错误");
            }
        }

function edit(obj,obj1,url){//要关闭的弹框类名 form表单id 编辑接口
  var token1 ='basic '+ window.sessionStorage.token;
  //这里的格式是按后台要求的 通过缓存读取Token
  var url = browerUrl+url;
  var obj1 = "#"+obj1;
  var formData = new FormData($(obj1)[0]);
  for(var x of formData){
    console.log(x)
  }

    beforeSend: function(request) {
            request.setRequestHeader("Authorization", token1);
          },
    //或者直接设置请求头
