1、主页面

• Home.vue

<template>
  <div class="home">
    <div><h1>管理主页</h1></div>
    <div>
          <el-tabs v-model="activeName" type="card" @tab-click="handleClick">
            <el-tab-pane label="商家列表" name="first"></el-tab-pane>
            <el-tab-pane label="产品列表" name="second"></el-tab-pane>
            <el-tab-pane label="重置密码" name="third"></el-tab-pane>
            <el-tab-pane label="管理员列表" name="fourth"></el-tab-pane>
          </el-tabs>
    </div>
    <div>
        <router-view/>
    </div>

  </div>
</template>

<script>
// @ is an alias to /src

export default {
  name: 'Home',
  data() {
      return {
        user: null,
        activeName: 'first',

      }
  },
  mounted() {
      let token = window.sessionStorage.getItem('token')
      if(token == null) {
          this.$router.push('/login')
          return
      }
      // 保存当前登录用户信息
      this.user = window.sessionStorage.getItem('user')
      

  },
  methods: {
        handleClick(tab, event) {
            console.log(this.activeName, tab, event);
            if(this.activeName == 'first') {
                this.$router.push('/index/seller')
            }
            else if(this.activeName == 'second') {
                console.log('second');
                this.$router.push('/index/product')
            }
            else if(this.activeName == 'third') {
                console.log('third');
                this.$router.push('/index/reset')
            }
            else if(this.activeName == 'fourth') {
                console.log('second');
                this.$router.push('/index/admin')
            }
        }
  }

}
</script>

2、子页面

• AdminList.vue

<template>
    <div>
        <h3>admin list</h3>
    </div>
</template>

<script>
</script>

<style>
</style>

• ResetPass.vue

<template>
    <div>
        <div><h3>reset password</h3></div>
    </div>
</template>

<script>
</script>

<style>
</style>

3、路由配置

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'Home',
    component: Home
  },
  {
    path: '/about',
    name: 'About',
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
  },
  {
    path: '/login',
    name: 'Login',
    component: () => import('../views/Login.vue')
  },
  {
    path: '/index',
    name: 'Index',
    component: Home,
    children: [
        {
          path: 'seller',
          component: () => import('../views/SellerList.vue')
        },
        {
          path: 'admin',
          component: () => import('../views/AdminList.vue')
        },
        {
          path: 'product',
          component: () => import('../views/ProductList.vue')
        },
        {
          path: 'reset',
          component: () => import('../views/ResetPass.vue')
        },
    ]
  },
]

const router = new VueRouter({
  routes
})

// 挂载路由导航守卫
router.beforeEach((to, from, next)=>{
	console.log("to="+to.path)
	console.log("from="+from.path)
	// to 要访问的路径
	// from 从哪个页面而来
	// next 是一个函数,表示放行
	// next() 放行, next('/Login')强制跳转
	// if(to.path === '/login') return next()
	// if(to.path === '/regist') return next()
    
	// 获取登录的状态
	// let token = window.sessionStorage.getItem("token")
	// if(!token) {
	// 	return next({path:'/login'})
	// }

	next()
})

export default router

4、文档结构
