JAVA模拟登录内网某个网页，一直接无法成功，求助！

1.网页源文件代码如下：

    <script type="text/javascript">
    var floatReload = function(){
        var maxHeight = document.getElementsByTagName("HTML")[0].offsetHeight;
        var maxWidth = document.getElementsByTagName("HTML")[0].offsetWidth;
        fBox = document.getElementById("box02");
        var marginTop = maxHeight - fBox.offsetHeight;
        fBox.style.marginTop = (marginTop > 340)?marginTop + "px":"340px"
        
        var messageBG = document.getElementById("messageBG");
        if(messageBG){

    }
    //window.onresize = floatReload;
    //floatReload()
    //设置透明
    new (function(){

        if(messageBG){
            var opacityPercent = 80;
            messageBG.style.filter = "alpha(opacity="+opacityPercent+")";
            messageBG.style.opacity = opacityPercent / 100;
        }
    })();
    </script>    </form>
</body>2.以下是我写的JAVA代码：
//package demo; import org.apache.commons.httpclient.*;import org.apache.commons.httpclient.cookie.*;import org.apache.commons.httpclient.methods.*; /**
 * 用来演示登录表单
 */public class FormLoginDemo2 {     static final String LOGON_SITE = "10.243.167.3";    static final int    LOGON_PORT = 80;        public static void main(String[] args) throws Exception{        HttpClient client = new HttpClient();        client.getHostConfiguration().setHost(LOGON_SITE, LOGON_PORT);              //模拟登录页面
        PostMethod post = new PostMethod("/login.aspx?ReturnUrl=%2f");        NameValuePair STATE = new NameValuePair("__VIEWSTATE", "/wEPDwULLTEyMDc3OTEzMTYPZBYEAgMPFgIeB1Zpc2libGVoZAIFD2QWBmYPFgIfAGgWBAIBDw8WAh4EVGV4dAUt6Lqr=");  NameValuePair ATION = new NameValuePair("__EVENTVALIDATION", "/wEWBAKA1rmsBgKpwK/OBgK1qbSRCwKC3IeGDA==");         NameValuePair name = new NameValuePair("txtLoginName", "nature");     
        NameValuePair pass = new NameValuePair("txtPassword", "12345678");             post.setRequestBody(new NameValuePair[]{STATE,ATION,name,pass});       int status = client.executeMethod(post);        System.out.println(post.getResponseBodyAsString());        post.releaseConnection();                //查看cookie信息        CookieSpec cookiespec = CookiePolicy.getDefaultSpec();        Cookie[] cookies = cookiespec.match(LOGON_SITE, LOGON_PORT, "/", false, client.getState().getCookies());       if (cookies.length == 0) {           System.out.println("None");           } else {           for (int i = 0; i < cookies.length; i++) {               System.out.println(cookies[i].toString());               }       }           }}
3.程序编译没有问题，用户名密码没有问题，但是执行的时候出现以下错误提示：

解决方案 »

  1.   

    粗略看了下，
    估计不能这么写，
    这个网页肯定是某框架的mvc自动生成的
    你程序里面的nameandpair是变动的而非固定
    所以弄成那个不行
      

  2.   

     value="/wEPDwULLTEyMDc3OTEzMTYPZBYEAgMPFgIeB1Zpc2libGVoZAIFD2QWBmYPFgIfAGgWBAIBDw8WAh4EVGV4dAUt6Lqr="value="/wEWBAL1s7SnCAKpwK/OBgK1qbSRCwKC3IeGDA=="这2个东东直接复制可能不行的，你可以看看每次打开那个登陆页面时不是一样的，如果不一样就不能以这种方式解决建议跟那个内网系统的开发者接触，了解其相关验证机制
      

  3.   

    呵，没办法跟开发者接触，这本身就是想利用程序做个自动回复，不能让他们知道的value="/wEPDwULLTEyMDc3OTEzMTYPZBYEAgMPFgIeB1Zpc2libGVoZAIFD2QWBmYPFgIfAGgWBAIBDw8WAh4EVGV4dAUt6Lqr="value="/wEWBAL1s7SnCAKpwK/OBgK1qbSRCwKC3IeGDA=="
    上面这两个的确是会变化的，如果能够实时抓取它们的值 就好了
      

  4.   

    你应该先用Getmethod方法登陆到这个网站上,然后用读取response信息,然后分析response获得hidden域的名字和值,然后加入到你post的参数中,提交就可以登陆了.
    但是我在执行一个类似的网站的时候,post登陆成功了,但是后续的redirect失败,你如果解决了,麻烦根我分享一下,谢谢.
