vue路由可以强制携带参数吗？

Question

定义了路由规则
`{

path: '/app_article/:id',
name: 'App_article',
component: App_article

}
`

我想让用户进入app_article页面时，必须强制携带参数。如果发现没有ID参数，自动让返回上一页

Answer 1

{
    path: '/app_article/:id',
    name: 'App_article',
    component: App_article,
    beforeEnter: (to, from, next) => {
        // 处理ID
        ...
    } 
}

Answer 2

{
    path: '/app_article/:id',
    name: 'App_article',
    component: App_article,
    beforeEnter: (to, from, next) => {
        let params = to.params;
        if (params.id !== undefined) {
            next(true)
        } else {
            next(false);
        }
    } 
}

Answer 3

在页面内处理的方式
created() {

if (!this.$route.query.id) {
  this.$router.go(-1)
  return
}

}
