  </div>
</template>  
  
<script setup lang="ts">  
import { ref } from 'vue';
import Avatar from '@/components/Avatar/index.vue'  
interface DataFace {
	img: string
	[propName: string]: any
}
const dataInfo = ref<DataFace>({ 
  img: 'https://img1.baidu.com/it/u=3717210657,1724010864&fm=253&fmt=auto&app=138&f=PNG?w=500&h=500'
})

</script>
<style lang="scss" scoped>
.avatar-box {
  width: 300px;
  display: flex;
  justify-content: center;
}
</style>
