關于如何搶到半佛仙人的支付寶紅包方法？✔

0x01 前言

每次打開b站發現半佛老師發的神秘代碼都早已被搶完，于是氣不過，看了一下半佛老師以往發的動态，尋求規律。emmmm，我看用腳本去擷取神秘代碼應該可行。

是以接着看下面具體分析。

0x02 具體分析

每次看到半佛老師發送的神秘代碼都是這樣的格式：【這段文本表示神秘代碼的音譯】

是以，我們首要的問題就是如何擷取這個神秘代碼呢？

我通過簡單的抓包，搜尋關鍵詞：代碼，找到疑似B站的Api。

輕按兩下打開這個連結，如下圖，找到神秘代碼的位置

确定該接口為擷取Bilibili動态消息的Api無誤。

于是，這個接口為:

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

(中間的半佛仙人的UID可以替換成任意B站賬号的UID)

以上接口都有了，傳回的資料格式是json。

那麼最後的問題就是，如何把半佛老師的發的神秘代碼轉換為數字呢？

畢竟大家都是從老婆手裡拿零花錢的人（🐶）

是以一頓操作猛如虎，結果非常amazing啊，找到了一個現成庫

pypinyin

（其實就是面向搜尋引擎程式設計，霧）

是以最後胡亂操作一下，就有了以下代碼。
