第一：带上CURLOPT_REFERER试试，对方是不是有可能判断了页面来源
第二：对方的登陆页是否有隐藏参数，如果有的话需要先访问登陆页获取隐藏值再提交
第三：没看见你什么地方提交了登录的账号和密码，就是自己这边POST过来的账号和密码
$url = "http://202.117.64.25/loginAction.do";
$fields = "dllx=dldl&zjh=201224080126&mm=201224080126";
这是提交账户和密码！
CURLOPT_REFERER 要加什么？
找到两个隐藏参数，但是貌似没什么用
第一：带上CURLOPT_REFERER试试，对方是不是有可能判断了页面来源
第二：对方的登陆页是否有隐藏参数，如果有的话需要先访问登陆页获取隐藏值再提交
第三：没看见你什么地方提交了登录的账号和密码，就是自己这边POST过来的账号和密码
帮你测试了一下，登录是没问题的，已经登录成功，主要问题出在你第二次请求的参数上，检查一下参数，抓取你第二个页面上所有的参数下来，另外JAVA的这个报错不是很懂！

大家帮忙看看，怎么回事？？？
你的流程和代码都有问题！正确的流程应该是：
1、访问 http://202.117.64.25/
获取 cookie。因为他的 sessionid 在这个页面发出的
2、访问 http://202.117.64.25/loginAction.do 并发送 post 表单数据
3、第2步返回的是一个框架页，你得根据需要进入某个框架
比如访问 http://202.117.64.25/menu/s_top.jsp 可以得到已登录信息：欢迎光临 黄小龙
