我正在开发一个登录系统，用于检查用户是否在特定用户组中。
如果用户在“访问”用户组中，那么我想向他们显示下一个表单。如果他们在用户组“注册用户”中，它将显示“抱歉，您没有访问权限”
这是我目前的代码：这将使用表单上显示的2个文本框登录。
我知道我不应该叫“gettext（）;”在密码字段但我不知道如何编码它所以htmlunit理解字符而不是放入数组的字符如果我写“getpassword（）”

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，以便您自己登录并查看。
（以此身份登录“您将进入用户组（”注册用户“）”）
用户名：stackoverflow
（测试用户信息）
答案 0 :(得分：1)
成功登录后，使用锚点击配置文件链接，然后使用span获取用户组。 代码的更改将是：
