一、二级路由
```
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
const router = new VueRouter({
//配置路由
routes: [
{ path: '', component: },
{ path: '/', component: },
{ path: '/', component: },
{ path: '/', component: },
{ path: '/', name: '', component: },
{ path: '/', redirect: '/' },
{ path: '/', component: ,children:{path:'/',component:}},
]
})
//路由守卫
router.beforeEach((to, from, next) => {
if (to.path === '/login') {
next()
} else {
let res = localStorage.getItem('login')
if (res) {
let isLogin = JSON.parse(res).isLogin
if (isLogin === 1) {
next()
} else {
next('/login')
}
} else {
next('/login')
}
}
})
export default router
```
