##### 3.7 router/index.js (路由模块代码)

```js
import Vue from 'vue'
import VueRouter from 'vue-router'
//导入前置路由地址数组
import Arrrouter from '@/router/router.js'

import Login from '@/components/MyLogin.vue'

Vue.use(VueRouter)

const router = new VueRouter({
  routes:[
    //路由重定向
    { path:'/',redirect:'/login'},
    //登录路由规则
    { path:'/login',component:Login},
    { 
      path:'/home',
      component:Home,
      //路由重定向
      redirect:'/home/users',
      children:[
        //路由重定向

##### 3.8 router (全局守卫路由路径)

```js
export default ['/home','/home/users','/home/orders','/home/rights','/home/setting']
```
