1、重定向 redirect

const routes = [{ path: '/', redirect: '/index'},{ path: '/index', component: index }
]

2、嵌套路由

const routes = [{ path: '/index', component: index,children: [{ path: 'info', component: info}]}
]

通过/index/info就可以访问到info组件了

3、懒加载

const routes = [{ path: '/index', component: () => import('@/views/index.vue')},{ path: '/hello', component: () => import('@/views/hello.vue') }
]
