vue使用keep-alive后退还是会刷新页面？

Question

App.vue

<template>
  <keep-alive>
    <router-view />
  </keep-alive>
</template>

components/comHeader

<i class="iconfont icon-back" @click="goBack"></i>

import { useRouter, useRoute } from 'vue-router'

const router = useRouter()
const goBack = () => {
  router.back()
}

使用vue3的vue-cli框架，页面后退都首页总是会刷新页面，加了keep-alive，依然还是一样是什么情况？

改版了，哥们

    <keep-alive :include="['A']">
      <component :is="Component"></component>
    </keep-alive>

你把需要缓存的组件放到 :include 数组中
