vue3.0之如何获取当前路由地址

三种方式

import { defineComponent, ref, reactive, watch, toRaw, getCurrentInstance } from 'vue';

const { proxy }: any = getCurrentInstance();
    console.log(proxy.$router.currentRoute.value);
    const router = useRouter();
    console.log(router.currentRoute.value);
    watch(
      () => router,
      (newValue, oldValue) => {
        console.log(newValue.currentRoute.value, '新的路由');
        console.log(newValue.currentRoute.value, '旧的路由');
      },
      { immediate: true }
    );
