如何在站点报废工具中绕过CAPTCHA [英] How to Bypass CAPTCHA in site scrapping tool

问题描述

大家好，

我正在使用网站报废工具，我正在使用C＃类WebClient来下载网站内容。经过一段时间（通常是5-10分钟），一些网站用验证码图片回复，有没有办法绕过验证码。我试图使用不同的免费代理，但其中许多不工作。我也尝试在连续呼叫之间插入相当长的时间间隔，但都是徒劳的。



是否有任何解决方案可以解决该问题，或者我的问题存在一些问题方法？



谢谢

Hi All,
I am working on a site scrapping tool, I am using C# class "WebClient" to download site content. After some time(usually 5-10 minutes) some sites response with captcha image, Is there any way to bypass the captcha. I have tried to use different free proxies but many of them dont work. I have also tried to insert fair amount of time interval between consecutive calls but all in vain.

Is there any solution for that problem or there is some inherent problem in my methodology?

Thanks

推荐答案

不，这是你方法论中的一个固有问题



如果有的话，Captcha系统会很快更新，以防止你绕过它。



这正是验证码的用途：确保它是人类浏览的，而不是网络机器人。

No, it's is an inherent problem in your methodology

If there was, the Captcha system would quickly be updated to prevent you getting round it.

That is exactly what captcha is there for: to make sure it is a human being browsing, not a web bot.

您可以使用 KnowCaptcha 的API来解决问题。

You can use the API of KnowCaptcha to solve the problem.
