是否可以解码验证码? [英] Is it possible to decode captcha code?

问题描述

大家好，

我的问题是可以解码验证码吗?"我的意思是，验证码图片中显示的任何代码，我们都可以将其包含在变量中吗?

如果可以，请解释一下该怎么做?还是可以提供任何示例代码?

其次，我不愿意使用任何第三方dll或其他东西.

在此先谢谢您.

Hi all,

My question is "Is it possible to decode captcha code?" I mean whatever code is displayed in captcha image, can we take it in variable?

If yes can anyone please explain how is it be done? Or can provide any sample code?

Second, I dont wnat to use any third party dll or something else.

Thanks in advance.

推荐答案

如果您尝试将验证码图片反转为需要输入的文本，那么可能就不用了-它们的设计方式使OCR变得困难如果不是不可能的话.不仅如此，还有一种称为reCaptcha的验证码变体，它使用人工对OCR软件无法解码的文本进行OCR.这被用作各种项目的一部分，尤其是将整个《纽约时报》数字化.

如果有办法的话，Captchas将立即变得更加困难以阻止您的软件运行！ :laugh:

If you are trying to reverse a Captcha image to the text it needs entered, then probably not - they are designed that way to make OCR difficult if not impossible. Not only that, but there is a variant of Captcha called reCaptcha which uses humans to do the OCR of text that OCR software could not de-code. This is used as part of various projects, notably to digitize the whole of the New York Times.

If there was a way, Captchas would immediately become much harder to prevent your software from working! :laugh:

如果您不想使用任何第三方dll，则可能需要支付一些费用才能开发出如此复杂的内容，正如其他人所说的那样，一个简单的事实就是您试图击败验证码的用途，这意味着它旨在使您难受，因此您很可能至少在某些时候会失败.

If you don''t want to use any third party dll, you probably need to pay some one to develop something as complex as this, and as others have said, the simple fact that you''re trying to defeat what captcha is written for, means that it''s designed to make it hard for you, so you''re likely to fail, at least some times.

此问题有两个答案.

是，取决于图像实现.有些比其他的更容易解码.

绝对不！"出于显而易见的原因，您根本无法获得任何帮助，并且您将被其他数字化项目的准确性所困扰.

There are two answers to this question.

"Yes", depending on the image implementation. Some are easier to decode than others.

"Absolutely NOT!" You''re not getting any help with doing this at all, for obvious reasons, and that you''ll be screwing with the accuracy of other digitizing projects.
