在Vue2.7中使用useRouter 和useRoute

在路由文件中添加下面两个函数替代，等官方相应API完成

export function useRouter() {
  return  router;
}

export function useRoute() {
  return router.currentRoute;
}

const router = new Router({
  mode: "hash",
  routes: [
    {
      path: "/",
      // component: () => import("@/pages/home/Home.vue"),
      component: Home
    },
  ],
});
