创建文件 /layouts/shortcodes/douban.html ，代码如下：

  <div id="db{{ .Get 0 }}" date-dbid="{{ .Get 0 }}" class="douban_item post-preview"></div>
</div>

            var url = "https://api.douban.com/v2/movie/subject/" + id + "?apikey=0dad551ec0f84ed02907ff5c42e8ec70";

{{</* douban id */>}}

补充说明 {#补充说明}

关于添加 js, css 代码，一般 hugo 主题都有 customJS 或 customCSS 选项（比如我的主题），我们可以添加到其中。

我不确定有几个人需要这个 douban shortcode ，因此，暂时没有整合到 hugo-theme-jane 中，如果有人需要，欢迎在此文章下留言。

最后，感谢原创作者林小沐！
