 <nuxt-link :to="{name:'about',query:{id:123}}">about</nuxt-link>

pages/
--| news/
-----| _id.vue
-----| index.vue
在index.vue中要根据不同的id跳到新闻详情页，这里有2种跳转方式，通过path和name
<nuxt-link :to="{path:'/news/123'}">news-1</nuxt-link>
<nuxt-link :to="{name:'news-id',params:{newdetail:'fff'}}">news-32</nuxt-link>
在_id.vue中可以接收到参数{{$route.params.newdetail}}

export default {
 validate ({ params，query}){
  // 必须是number类型
  return /^\d+$/.test(params.id)
 }
}

module.exports = {
  router:{
  middleware: 'check-auth'
 }
}
