vue-admin-template 动态路由步骤
api/user.js存放接口
import request from '@/utils/request'
// 登录
export function login(data) {
return request({
url: '/auth',
method: 'post',

})
}
// 用户信息
export function getInfo(token) {
return request({
url: '/api/v1/userInfo',
method: 'get',
params: {
token }
})
}
// 退出
export function logout() {
return request({
url: '/logout',
method: 'GET'
})
}
// 登录接口返回数据

"token":"eyJhbGciOiJIUzI1NiIsInR5...mdOL7Tjkqc-sY","type":"Bearer","user_info":{
"role":[],"user_id":1,"username":"admin"}},"msg":"ok"}
// 用户信息接口返回数据 userinfo

* alwaysShow: true if set true, will always show the root menu
* if not set alwaysShow, when item has more than one children route,
* it will becomes nested mode, otherwise not show the root menu
* redirect: noRedirect if set noRedirect will no redirect in the breadcrumb
* name:'router-name' the name is used by (must set!!!)
* meta : {
roles: ['admin','editor'] control the page roles (you can set multiple roles)
title: 'title' the name show in sidebar and breadcrumb (recommend set)

修改菜单循环渲染
全部代码如下：

<el-scrollbar wrap-class="scrollbar-wrapper">
<el-menu

:base-path="route.path"
