1.cookie localStorage sessionStorafe的区别

1 cookie中  2 localStorage  3 sessionStorage

cookie 可以设置过期时间，借助于第三方模块，vue-cookies
    -cnpm install vue-cookies -S
    -main.js中
        import cookies from 'vue-cookies'
        Vue.prototype.$cookies = cookies;
localStorage：永久存储
sessionStorage：关闭浏览器就失效

2.下载vue-cookie

cnpm install vue-cookies -S

3.main.js

import cookies from 'vue-cookies'
Vue.prototype.$cookies = cookies;
