小众豆瓣已成刚需，电影、图书看完都会标记下，写日志时常会提到，老想着在文章内「优雅」地展示，官方 API 已废，幸好还有给力的 @mufeng 兄，以下功能就使用其提供的轮子。
换用轮子：https://github.com/cxfksword/douban-api-rs
效果如下
2020 / 法国 比利时 / 剧情 悬疑 惊悚 / 雅恩·戈斯兰 / 皮埃尔·尼内 璐·德·拉格
使用方式
如果是md的话之间输入以下格式，其他输入a标签链接，注意链接以 / 斜杠结尾。
<https://movie.douban.com/subject/34953719/>
<https://book.douban.com/subject/35254632/>
