Java HTMLUnit登录不工作？

我有以下代码到我的网站，我想登录到如下所示。当我运行它时没有错误消息，但它在最后返回的HTML是原始登录页面的HTML，表明我没有登录。我曾在多个网站上尝试过，但同样的事情一直在发生，所以我不确定它是否在我想要的时候不让我登录，或者它是否与我转到另一个页面时没有记住cookies有关

任何帮助都将不胜感激

String html = Jsoup.connect("pagerequiringlogintoaccess.com").get().html();


System.out.println(html);
  }

我以前遇到过这个问题，为了解决这个问题，我创建了运行所有函数的方法：setText、getEid和click。它们是：

 public void click(HtmlElement el) throws Exception{
    page = el.click();
  }

  public void setText(HtmlElement el, String text){
    HtmlTextInput input = (HtmlTextInput)el;
    input.setText(text);
  }

 public HtmlElement getEid(String id){
    HtmlElement rval = null;
    boolean looking = true;
    int counter = 0;
    while(counter < elementRetryCount && looking){
      try{
        rval = page.getHtmlElementById(id);
        looking = false;
      } catch (Exception e){
        try {
          Thread.sleep(elementRetryTimer * 1000);
        } catch (InterruptedException e1) {
          e1.printStackTrace();
        }
      }
      counter ++;
    }
    return rval;
  }

希望这些改变能有所帮助

scraper.setText(scraper.getEid("txtFromDate"), startingDate);
scraper.click(scraper.getEid("btnSubmit"));
