HtmlUnit单击submitinput，但页面未更新

Question

第一篇文章。 我正在尝试解决使用dvwa的HtmlUnit问题。 当我尝试单击代码的doFormPost部分中的Submit按钮时，它向我显示的是文本字段仍为满的旧页面，而不是新页面。 从字面上的等待直到页面更改到让它等待3分钟，然后重新检查，但我并未尝试找出一切可能的解决方法。 我希望这里的人可能知道发生了什么事。 先感谢您。

只需单击提交按钮即可使用：

HtmlSubmitInput submit = (HtmlSubmitInput) form.getFirstByXPath("//input[@value='Submit']");
HtmlPage myPage = submit.click();

如果没有，您可以尝试以编程方式发出POST请求。 此处的示例： https : //colinhowe.wordpress.com/2009/06/24/htmlunit-how-to-do-a-post/

Final WebClient webClient = new WebClient();

// Instead of requesting the page directly we create a WebRequestSettings object
WebRequestSettings requestSettings = new WebRequestSettings(
  new URL("URL GOES HERE"), HttpMethod.POST);

// Then we set the request parameters
requestSettings.setRequestParameters(new ArrayList());
requestSettings.getRequestParameters().add(new NameValuePair("name of value to post", "value"));

// Finally, we can get the page
HtmlPage page = webClient.getPage(requestSettings);
