Facebook驗證碼

我試圖在c＃中獲取Facebook的驗證碼圖像，然後將其顯示在我的應用程序中，並將回覆發送回Facebook。我的應用程序工作正常，基本上與Facebook通信，但過了一段時間它要求驗證碼。我加入了輸入驗證碼的功能，當我使用webclient將它發送到Facebook時，我得到了它的響應。但是，當我再次嘗試查詢數據時，我又被引導至驗證碼鏈接，並且循環繼續。Facebook驗證碼

我只是無法弄清楚我是如何在隨後的請求中附加信息的，我已經輸入了captcha或從captcha響應頭返回了哪些信息，我應該附加到我的新請求中。

對不起，我英文很差。我希望我傳達了這個信息。

您應該比較您正在發送的數據與手動在瀏覽器中進行比較的情況。我會特別檢查HTTP請求的頭字段。

這就是我正在做的。我在檢查標題的同時提出了請求，然後將響應標題附加到我的下一個請求中。我正在通過firefox中的TemperData檢查標題。如果我發佈我的代碼給你，它會幫助你嗎？ –

是的，當然不是！ –

我已將代碼添加到原始帖子中。我基本上編寫了一個方法，它將一個數字作爲輸入，然後在Facebook上對其進行查詢，如果滿足'sometext'條件則返回true，如果我獲得了驗證碼，我將驗證碼圖像讀取，然後將驗證碼放入文件中我的程序讀取它並傳遞到Facebook。然後我再次發送驗證碼請求。我知道代碼太臃腫了。但現在我不想寫一個完整的應用程序，我現在只是在爲我的任務做一個PoC。 –
