java - 使用java和htmlunit获取vbulletin中用户的用户组

Question

我正在开发一个登录系统，用于检查用户是否位于特定的用户组中。

如果用户位于用户组“Access”中，那么我想向他们显示下一个表单。如果他们位于“注册用户”用户组中，则会显示“抱歉，您没有访问权限”

这是我到目前为止的代码:这将使用表单上显示的 2 个文本框进行登录。

我知道我不应该调用“gettext();”在密码字段上，但我不知道如何编码，以便 htmlunit 理解字符，并且如果我写“getpassword()”，则不会放入数组的字符

如果登录成功，我想开始检查用户的用户组 ID。如果我登录，我的用户组是管理员。我将添加一个测试用户，以便您可以登录并亲自查看。

(使用“您将属于用户组(“注册用户”)”登录)

论坛网址:http://svergja.com/forum

用户名:stackoverflow

密码:stackit123

(测试用户信息)

Answer 1

登录成功后，使用anchor点击个人资料链接，然后使用span获取用户组。 代码的更改将是:

   private void Login() throws FailingHttpStatusCodeException, MalformedURLException, IOException
        {
            WebClient client = new WebClient();
            client.setJavaScriptEnabled(false);
            HtmlPage page = client.getPage("http://svergja.com/forum/");

            HtmlForm form = (HtmlForm) page.getElementById("navbar_loginform");

            HtmlTextInput username = (HtmlTextInput) page.getElementById("navbar_username");
                username.setValueAttribute("stackoverflow");
            HtmlPasswordInput password = (HtmlPasswordInput) page.getElementById("navbar_password");
                password.setValueAttribute("stackit123");
            HtmlSubmitInput button = form.getInputByValue("Log in"); 
            page = button.click();

            List<HtmlAnchor> anchorList = page.getAnchors();
                for (HtmlAnchor htmlAnchor : anchorList) {
                    if(htmlAnchor.getAttribute("href").contains("member.php?"))
                    {
                        page = htmlAnchor.click();
                    }
                }

                HtmlSpan span = (HtmlSpan) page.getElementById("userinfo");
                DomNodeList<DomNode> nodeList = span.getChildNodes();

                    for (DomNode domNode : nodeList) {

                        NamedNodeMap map = domNode.getAttributes();
                        Node node = map.getNamedItem("class");
                          if(node != null && node.getNodeValue() != null && node.getNodeValue().equals("usertitle"))
                          {
                                System.out.println("The usergroup is "+domNode.getTextContent());
                          }
                    }
            }
