+楼层是越翻越小的, 所以 `next` 也要越来越小.

 看到了傻吊网友们的评论是不够的, 我们还想看到杠精与其隔着屏幕对喷的场景, 因此我们要获取评论的子评论, 即评论的评论

 ## 获得一个视频的弹幕
 看评论自然不够刺激, 我们想看到弹幕!

-//TODO
+获取弹幕非常简单
+
+```kotlin
+val danmakuFile = bilibiliClient.danmakuAPI.list(aid = 810872, oid = 1176840).await()
+```
+
+弹幕是一个文件, 可能非常大, 里面是二进制内容.
+
+为了解析弹幕, 我们要用到另一个类
+
+```kotlin
+val (flagMap, danmakuList) = DanmakuParser.parser(danmakuFile.byteStream())
+```
+
+`flagMap` 类型为 `Map<Long, Int>` 键和值分别表示 弹幕ID 与 弹幕等级.
+
+弹幕等级在区间 \[1, 10\] 内, 低于客户端设置的 "弹幕云屏蔽等级" 的弹幕将不会显示出来.
+
+`danmakuList` 类型为 `List<Danmaku>`, 内含所有解析得到的弹幕.
+
+使用以下代码来输出全部弹幕的内容
+
+```kotlin
+danmakuList.forEach {
+    println(it.content)
+}
+```
+
+客户端的弹幕屏蔽设置是对弹幕中的 `user` 属性做的. 而实际上 `danmaku.user` 是一个字符串.
+
+这个字符串是 用户ID 的 `CRC32` 的校验和.
+
+众所周知, 一切 hash 算法都有冲突的问题. 这也就意味着, 屏蔽一个用户的同时可能屏蔽掉了多个与该用户 hash 值相同的用户.
+
+在另一方面, 通过这个 `CRC32` 校验和进行用户 ID 反查, 将查询到多个可能的用户, 因此无法确定一条弹幕到底是哪个用户发送的.
+
+番剧的弹幕同理.
