Java HtmlUnit用户名和密码登录返回登录页

Question

我想用有效的用户名和密码使用HtmlUnit执行登录。成功登录后，我想在结果页面上执行一些操作。问题是我无法通过登录阶段 - 我一直在同一页面。奇怪的是，我记录了HtmlUnit Scripter Firefox插件的成功登录，然后重播了结果代码 - 同样的问题。有任何想法吗？

下面是代码：

<pre> 
import com.gargoylesoftware.htmlunit.BrowserVersion; 
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException; 
import com.gargoylesoftware.htmlunit.WebClient; 
import com.gargoylesoftware.htmlunit.html.HtmlElement; 
import com.gargoylesoftware.htmlunit.html.HtmlPage; 
import com.gargoylesoftware.htmlunit.html.HtmlPasswordInput; 
import com.gargoylesoftware.htmlunit.html.HtmlTextInput; 

import java.io.IOException; 
import java.net.MalformedURLException; 
<code> 
public class LoginSimulation 
{ 
    public static void main(String args[]) 
    { 
      HtmlPage page = null; 
      String url = "http://www.ravmilim.co.il/naerr.asp"; 

      WebClient webClient = new WebClient(BrowserVersion.FIREFOX_3_6); 
      webClient.setThrowExceptionOnScriptError(false); 

      try 
      { 
       page = webClient.getPage(url); 

       HtmlTextInput userInput = (HtmlTextInput) page.getElementById("txtUser"); 
       userInput.setValueAttribute("[email protected]"); 

       HtmlPasswordInput passwordInput = (HtmlPasswordInput) page.getElementById("txtPass"); 
       passwordInput.setValueAttribute("5750201"); 

       HtmlElement theElement2 = (HtmlElement) page.getElementById("submitButton"); 
       page = theElement2.click(); // the login does not work. Login page is displayed again 

       System.out.println(page.asText()); 
       webClient.closeAllWindows();    
      } 
      catch (FailingHttpStatusCodeException e1) 
      { 
       System.out.println("FailingHttpStatusCodeException thrown:" + e1.getMessage()); 
       e1.printStackTrace(); 
      } 
      catch (MalformedURLException e1) 
      { 
       System.out.println("MalformedURLException thrown:" + e1.getMessage()); 
       e1.printStackTrace(); 
      } 
      catch (IOException e1) 
      { 
       System.out.println("IOException thrown:" + e1.getMessage()); 
       e1.printStackTrace(); 
      } 
      catch(Exception e) 
      { 
       System.out.println("General exception thrown:" + e.getMessage()); 
       e.printStackTrace(); 
      } 
    } 

}

看起来你的代码就可以了。我已经手动尝试过，有时会记录，有时候不会。问题出在登录操作后出现的弹出窗口中。 你可以看到它从页面上的JavaScript：

if ($("#ErrorDuplicationLogin").text() != '') 
    {  
    $(".PopUpContent").show(); 
    $(".pagePopBackground").show();      

    } 

}); 

所以尝试登录和注销手动，之后启动程序。另外不要忘记使用HtmlUnit注销。谢谢。
