1.參考權(quán)限token校驗(yàn)
router.beforeEach((to, from, next) => {

   if (to.meta.requireAuth) {
       if (store.state.token) {
            next();
        }
    }else {
        next({
            path: '/login',
            query: {redirect:to.fullPath}  
        })
    }
}
else {
    next();
}

})

const router = new VueRouter({ ... })

router.beforeEach((to, from, next) => {
// ...
})

使用beforeRouteUpdate ，傳送門：https://router.vuejs.org/zh-c...

const User = {
  template: '...',
  beforeRouteUpdate (to, from, next) {
    // react to route changes...
    // don't forget to call next()
  }
}
