# PLAYER Refresh Token

> App.vue[color=blue]

:baby_chick: 新增屬性 **created()**
:baby_chick: 讓每次進入網頁的時候都先 Refresh Token
:baby_chick: 使用vuex的dispatch去找actions來用

export default {
  components:{
    myHeader,
    myFooter
  },
  //在每次載入之前，先重置token
  created(){
    this.$store.dispatch('admin/refreshToken');
  }
}
