嵌套路由就是路由里面嵌套他的子路由，可以有自己的路由导航和路由容器（router-link、router-view），通过配置children可实现多层嵌套

//mine组件
<template>
    <div class="content">
        在mine的组件里面嵌套路由
        <router-link to="/mine/c">去到Cpage</router-link>
        <router-link to="/mine/d">去到Dpage</router-link>
        <div class="child">
            <router-view></router-view>
        </div>
    </div>
</template>

//router.js
//引入需要的组件，下是我的路径
import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/components/home'
import Mine from '@/components/mine'
import Cpage from '@/page/mine/c'
import Dpage from '@/page/mine/d'
Vue.use(Router)

export default new Router({
  routes: [
    {   
        path: '/',
        redirect: 'home'
    },
    {
      path: '/home',
      name: 'home',
      component: Home
    },
    {
      path: '/mine',
      name: 'Mine',
      component：Mine,
      children:[
        {
            path:'/',
            component:Cpage,
        },
        {
            path:'/mine/c',
            component:Cpage,
        },
        {
            path:'/mine/d',
            component:Dpage,
        }
      ]
      //children这是嵌套的部分
    },

//c.vue
<template>
    <div class="top-80">
        c.vue
        <p>这里Cpage文件</p>
    </div>
</template>


//d.vue
<template>
    <div class="top-80">
        d.vue
        <p>这里Dpage文件</p>
    </div>
</template>

嵌套路由通过配置children可实现多层嵌套，其它规则写法一样；
