web.py在SAE中的Session問題解決方法（使用mysql存儲(chǔ)）

這篇文章主要介紹了web.py在SAE中的Session問題解決方法（使用mysql存儲(chǔ)）,本文直接給出實(shí)現(xiàn)代碼,代碼中包含詳細(xì)注釋,需要的朋友可以參考下

這段時(shí)間一直想嘗試著在SAE中使用Python，初步選擇了Web.py框架做為開發(fā)框架，但是可憐SAE上的資料少的可憐，有點(diǎn)問題基本上解決不了，今天解決一個(gè)Session在Session的存儲(chǔ)問題,在SAE中不能直接用本地文件存儲(chǔ)，好像是權(quán)限的原因，我現(xiàn)在采用的是保存在mysql中，效果也不錯(cuò)。希望對(duì)大家有幫助。直接上代碼了。
