那个高手用JAVA实现过识别图片验证码的JAVA原程序？20分全部奉送！

[treeroot]

200分估计也没人写的出来

那倒也不一定,关系是看验证图片的复杂程序,我写了个CSDN的识图程序,方法很简单,比较图的像素值,因为CSDN的数字是不变的.

楼上的太小儿科了，

人家随便来点背景噪音，font的name, style, size每个都不一样，再来点英文，你怎么办？

别的不说，

我在这个生成这个图像的程序里面加上检查Http Request的header参数中的referer（也就是这个<img src>标签包含在哪个网页中），只有来自我自己网站的网页的img的请求，我才接受，你怎么办？

[yagumo]

我第一句话就说了要看图片的复杂程序,不晓得你是没看到还是故意无视.还有,referer才叫小儿科,这些东西一个setRequestProperty就搞定了.
