一、拆分
新建包：
Aside和Header都是组件
User为视图
Aside.vue：
<template>

active-text-color="#ffd04b"
:collapse-transition="false"
:collapse="isCollapse"
>
<div style="height: 60px; line-height: 60px; text-align: center">
<img src="../assets/logo.png" alt="" style="width: 20px; position: relative; top: 5px; right: 5px">

</div>
<el-menu-item index="/">
