如果有 则生成一条uuid相册信息 插入其中
如果没有 则代表新建相册 需要将生成的uuid 存入redis里缓存起来 等待相册创建提交

AddComment 添加评论

func (ArticleService) ArticleMaintainQuery 

func (articleservice ArticleService) ArticleMaintainQuery(query *data.ArticleMaintainQuery) ([]*data.ArticleMaintainResponse, *data.PageInfo, error)

ArticleMaintainQuery 文章大概查询 逻辑: 如果 category name 和 content都为空 直接从redis里查热门数据article id再查mongo 如果只有category name的话 从redis里查出该分类的集合 剩下的就直接查mongo #issue 这里有一个Bug 当用户新增文章时 缓存没更新的话 是查不到才添加的数据的 所以在添加文章时再掉一次重新排序这种临时的方法来解决这一问题
