首先要清楚discuz論壇發帖的流程，簡單地說就是以下流程：

進入登錄頁 ->登錄 -> 進入版面 ->發帖

登錄和發帖時要獲取到頁面的formhash值，否則會失敗，如果啟用了驗證碼，還得去分析驗證碼，這就比較復雜了。這里只用python來描述這一系列過程，涉及到驗證碼還請大家自行去實現。

discuz類中只有一個公開方法
def post(self,subject,wysiwyg,content)
三個參數，分別是帖子標題、是否是可視化編輯、帖子內容。
類實例化時會進行登錄操作，并同時記錄下cookie以備用，post方法中會啟用多個線程執行私有方法__posttopic(self,**para)進行真正的發帖操作。
所以，基本上discuz生成的formhash就是一個雞肋 -_-
