这个 cookie.txt

register.pandi.or.id    FALSE   /   FALSE   0   JSESSIONID  05CA8241C5B76F70F364CA244E4D1DF4

提交表单后显示

HTTP/1.1 200 OK Date: Wed, 27 Apr 2011 07:38:08 GMT Server: Apache-Coyote/1.1 X-Powered-By: Servlet 2.4; Tomcat-5.0.28/JBoss-4.0.0 (build: CVSTag=JBoss_4_0_0 date=200409200418) Content-Length: 0 Via: 1.1 register.pandi.or.id Content-Type: text/plain X-Pad: avoid browser bug

如果不是错误“验证码无效” 总是登录pandi失败 我的脚本有什么问题？
我不想破解验证码，但我想从我的网页上显示验证码和用户输入的验证码，这样用户就可以从我的网站上自动注册域 dotID

验证码旨在区分人类和机器人(程序)。似乎您正在尝试使用程序登录。验证码似乎完成了它的工作:)。

我看不到合法的解决方法。
