token保存方法第一步安装

npm i js-cookie //安装

第二步在main.js引入

import cookie from 'js-cookie';
Vue.prototype.$cookie = cookie; 

第三步赋值调用

var $cookie = this.$cookie;
//赋值
this.$cookie.set('token',$result.data.token)
//调用
headers:{
       Authorization:this.$cookie.get('token')
      }
//删除token
this.$cookie.remove("token")      

localStorage保存方法赋值

localStorage.setItem("key_token", result.data.token);

删除localStorage指定键对应的值

localStorage.removeItem('token');

删除localStorage所有值

localStorage.clear('token');
