如何获得验证码的图片链接? [英] How to attain link of images of CAPTCHA?

问题描述

有什么方法可以获取CAPTCHA的图像链接?
我有一个使用WebBrowser控件的C#程序，该程序可在整个Web中工作，而我只能访问其中的HTML TextDocument.面对验证码时，它必须将图像重定向到表单中的用户.问题是我找不到图像链接.
有什么方法可以在不从浏览器输出屏幕的整个或特殊矩形中拍照的情况下抓取图像吗?

Hi,
Is there any way to attain link of images of a CAPTCHA?
I have a C# program using WebBrowser control that works through the web in which I have access just to HTML TextDocument of it. When it faces a CAPTCHA, it has to redirect the image to the user in a form.The problem is that I can not find the image link.
Is there any way to grasp the image without taking photo from the whole or special rectangle of browser output screen?

A CAPTCHA is just an image link, so, not really. And you''d need a browser plug in to intercept the image, a web browser control will still just download it.

好，
在哪里可以找到浏览器插件来拦截图像?

OK,
Where can I find the browser plug in to intercept the image? And does it work on a WebBrowser as a control?
