我的博客地址：博客地址，点击访问可以查看评论区。
- 效果图如下
支持评论和多级回复
废话不多说，vue代码如下：
- 评论组件

- 如果需要使用评论组件只需要在指定位置引入即可，代码如下：
- 在当前vue中要先引入该评论组件。才能使用！！
<Comment :commentList="commentList" :blogId="blogId" @on-comment="showCommentById"></Comment>
- showCommentById
//根据id查询该博客的评论信息
async showCommentById(id) {
const {data: result} = await this.$http.get("getListByBlogId/" + id)
if (result.code === 200) {
this.commentList = result.data
} else {
this.$Message.success(result.message)
}
},
