* 用法和 /threads/listPosts 相似，和 /threads/post 的区别也只有 include 字段不同
* 这个能够返回已删除评论，所以也不需要 include=deleted 了
* sort 字段提供三个取值：
* - desc （升序）
* - asc （降序）
* - desc （降序）
* - asc （升序）
* - popular（最热）
* 这个 API 的问题在于被嵌套的评论总是降序，看起来很不习惯
*
* 只获取一次使用 popular 排序的评论，之后在本地进行排序：
* 1. 将存在 parent 的使用 createdAt 进行升序并存放在 disqusjs.comment.popular
* 2. 将全部评论再进行升序排序，存放在 disqusjs.comment.desc
* 3. 将没有 parent 的条目进行升序排列存放在 disqusjs.comment.asc
* 每次加载翻页评论的时候 concat 并进行重排序
* 用户切换排序方式的时候直接取出进行重新渲染
