import { reactive, ref } from 'vue';
import { useRoute,useRouter } from 'vue-router';
const router = useRouter()
const query = reactive(router.currentRoute.value.query)
const params = reactive(router.currentRoute.value.params)
console.log('页面参数：', query, params)

import { useRoute } from 'vue-router'; 
const { query, params } = useRoute();
