1. window.onload 来刷新页面, 页面会白一下，交互效果不好
2. router.go(0) 来刷新页面, 页面会白一下，交互效果不好
3. provide, inject配合router来刷新页面
   1.在app.vue中

<template>
  <router-view v-if="isRouterActive"></router-view>
</template>
<script lang="ts" setup>
import { ref, provide, nextTick } from 'vue-demi'
const isRouterActive = ref(true)
provide('reload', () => {
  isRouterActive.value = false
  nextTick(() => {
    isRouterActive.value = true
  })
})
</script>

在需要调用刷新的组件中

import {  inject } from 'vue-demi'

const reload = inject('reload')

const updateFun = () => {
  reload()
}
