嗨，我使用Wso2身份服务器创建了策略。此策略基于主题，即电子邮件utsav@domain.com。同时评估其给出结果为不适用。请帮我做同样的..。

Answer 1

在您的策略中，它正在查找名为"http://wso2.org/claims/emailaddress“的属性id，并且它在您的请求中不可用。

请检查您的请求，如下所示，您正在发送具有不同属性id的电子邮件地址。

另外，如果您希望只使用XACML请求发送用户名，并且希望使用PIP属性查找器检索电子邮件。您可以在策略中使用"http://wso2.org/claims/emailaddress“属性id。这是从WSO2标识服务器用户存储中检索策略的属性id。您可以使用用户配置文件创建用户并将电子邮件地址设置为"utsav@domain.com“。然后，一旦发送只有用户名PIP的请求，PIP就会从用户存储中检索相应的属性值。
