vue3: Get the current routing address

// router的 path: "/user/:uid"
<template>
  <div>user</div>
  <p>uid: {
   
   { uid }}</p>
</template>
 
<script>
import { defineComponent } from "vue";
import { useRouter } from "vue-router";
 
export default defineComponent({
  name: "User",
  setup() {
    const router = useRouter();
    const uid = router.currentRoute.value.params.uid;
    return {
      // 返回的数据
      uid,
    };
  },
});
</script>

useRouter()What is returned is objectsimilar to that of vue2this.$router

router.currentRouteIt's RefImplan object, that is, we use refthe returned object to .valueaccess the current route, similar to vue'sthis.$route
