Python影象識別參考：http://www.th7.cn/Program/Python/201602/768304.shtml

指令碼思路：瀏覽器頁面到達驗證碼輸入頁面，針對驗證碼圖片進行另存為儲存到本地，然後將圖片複製到pytesser資料夾下（只有指令碼和圖片都在該資料夾下才能完成識別），然後呼叫Python圖片識別處理驗證碼圖片函式並返回驗證碼，然後就可以完成驗證碼輸入操作！

運用到的模組：python圖片識別、Python模擬鍵盤、Selenium滑鼠事件

第一步：在C:\Python27\Lib\site-packages\pytesser路徑下建立該Python檔案，用作圖片識別的方法

第二步：實際場景呼叫圖片識別

PS：登入驗證碼無需通過該方法處理，可以直接通過新增Cookie來繞過登入驗證碼，然後該方法只能識別一些簡單的圖片驗證碼！
