二级路由,由叫嵌套路由

一、配置

{
            path: '/city',
            name: 'city',
            component: City,
            children:[
                {
                    path:'hotCity',
                    component:()=>import('@/components/HotCity')
                },{
                    path:'newCity',
                    component:()=>import('@/components/NewCity')
                }
            ]
}

二、在city.vue组件中配置router-view

<template>
  <div>
      <router-view></router-view>
    <p>city</p>
  </div>
</template>
