使用htmlunit登录vbulletin论坛

我正在尝试使用htmlunit登录vbulletins论坛

i am trying to login vbulletins forum using htmlunit

我可以连接到我的论坛并设置我的用户名和密码，但是当单击登录按钮时，我无法登录我的用户

i can connect to my forum and set my username and password but when click in login button i can not login into my user

这是我的代码:

try{

        final WebClient webClient = new WebClient();

        webClient.getOptions().setJavaScriptEnabled(false);
        webClient.getOptions().setCssEnabled(false);        



        final HtmlPage page1 =(HtmlPage) webClient.getPage("http://mysite.com/forum.php");

        final HtmlForm form1 = (HtmlForm) page1.getElementById("navbar_loginform"); 

        final HtmlSubmitInput button= form1.getInputByValue("login"); 
        final HtmlTextInput username = form1.getElementById("navbar_username");

        final HtmlTextInput password = form1.getElementById("navbar_password_hint");


        username.setValueAttribute(txtusername.getText());
        password.setValueAttribute(String.valueOf(txtpasswd.getPassword()));


       final HtmlPage page2 =button.click();


        webClient.closeAllWindows();

    }
    catch(Exception x)
    {
        JOptionPane.showMessageDialog(null, "can not connect");
    }

当我得到page2的网址时，结果就像 "http://mysite.com/login.php?s=36401731df153421f06a8497b3b859df&do=登录"

when i get url of page2 result is like "http://mysite.com/login.php?s=36401731df153421f06a8497b3b859df&do=login"

请帮助我解决我的问题，谢谢
