vue如何实现权限控制路由(vue-router 动态添加路由)

用户登录后返回权限菜单，前端根据权限菜单动态添加路由，然后再动态生成菜单栏。

思路如下：

一、定义初始化默认路由。

二、动态配置路由，这里是把所有组件中相应的路由配置成一个个的对象，根据后台返回的菜单tree一个个去匹配。

三、通过匹配，把匹配好的路由数据addRoutes到路由中。

四、为了防止刷新页面后路由数据被清空，这里用判断是否登录的方式，再次加载动态路由。

具体代码如下：

router.js

import Vue from 'vue'
import {router} from './index'
import login from '@/views/login/login'
import layout from '@/views/layout/layout'
import home from '@/views/home/home.vue'
