在App.vue文件中添加provide ，isRouterAlive。在需要刷新的页面添加inject: [“reload”],

<template>
    <div id="app">
        <router-view v-if="isRouterAlive" />
    </div>
</template>

<script>
export default {
  name: 'App',
  provide () {
    return {
      reload: this.reload
    }
  },
  data () {
    return {
      isRouterAlive: true
    }
  },
  methods: {
    reload () {
      this.isRouterAlive = false
      this.$nextTick(function () {
        this.isRouterAlive = true
      })
    }
  }
}
</script>

<style lang="scss">
@media (max-width: 1920px) {
    body,
    html {
        font-size: 16px;
