0x01 前言

每次打开b站发现半佛老师发的神秘代码都早已被抢完，于是气不过，看了一下半佛老师以往发的动态，寻求规律。emmmm，我看用脚本去获取神秘代码应该可行。

因此接着看下面具体分析。

0x02 具体分析

每次看到半佛老师发送的神秘代码都是这样的格式：【这段文本表示神秘代码的音译】
因此，我们首要的问题就是如何获取这个神秘代码呢？
我通过简单的抓包，搜索关键词：代码，找到疑似B站的Api。

双击打开这个链接，如下图，找到神秘代码的位置

确定该接口为获取Bilibili动态消息的Api无误。
于是，这个接口为:

https://api.vc.bilibili.com/dynamic_svr/v1/dynamic_svr/space_history?host_uid=半佛仙人的UID&offset_dynamic_id=0&need_top=1

(中间的半佛仙人的UID可以替换成任意B站账号的UID)
以上接口都有了，返回的数据格式是json。
那么最后的问题就是，如何把半佛老师的发的神秘代码转换为数字呢？

毕竟大家都是从老婆手里拿零花钱的人（🐶）

所以一顿操作猛如虎，结果非常amazing啊，找到了一个现成库pypinyin（其实就是面向搜索引擎编程，雾）
所以最后胡乱操作一下，就有了以下代码。
