我试图在c＃中获取facebook验证码图像，然后将其显示在我的应用中并将回复发送回Facebook。我的应用程序工作正常，基本上与Facebook通信，但过了一段时间，它要求验证码。我合并了输入验证码的功能，当我使用webclient将其发送到Facebook时，我得到了它有效的响应。但是，当我再次尝试查询数据时，我再次定向到验证码链接并继续循环。
我无法弄清楚如何在我后来的请求中附加信息，我已经输入了验证码，或者我应该附加到我的新请求中的验证码响应标头返回的信息。
抱歉我的英语不好。我希望我传达了这个信息。

您应该准确地比较您发送的数据与手动在浏览器中执行此操作时的数据。 我会特别检查HTTP请求的标头字段。
