就useRoute和 useRouter分别对应vue2中的this.$route和this.$router其他的使用方法都一样

import { useRoute, useRouter, onBeforeRouteUpdate } from "vue-router";

setup(){
const route = useRoute();
const router = useRouter();
console.log(route.query)
router.push({path:'/home'})
onBeforeRouteUpdate((to: any) => {
      console.log(to, "=====");
 });
}
