WSO2身份，XACML简单编辑器，尝试工具-规则评估

Question

我使用Simple Editor工具用XACML编写了一个基本的测试用例。

我的规则:"只有医生可以访问医疗记录"

当使用角色名"admin"时，一切正常，请求的答案是"permit"。如果我在策略和请求中更新角色，并将其设置为值:"doctor"，那么规则引擎将返回错误的"deny"。为了进行测试，我还记录了一个用户角色名，其值为"doctor"，这是所需的值，并在WSO2控制台下添加了一个ID。

为什么在WSO2下XACML在使用其他角色而不是"医生"时不断拒绝任何评估请求?(参见下面的策略和请求语句)

感谢您的反馈和支持。

Answer 1

既然您已经添加了http://wso2.org/claims/role作为主题的AttributeId，下面应该是您的XACML请求

<?xml version="1.0" encoding="UTF-8"?>
<Request xmlns="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17" CombinedDecision="false" ReturnPolicyIdList="false">
   <Attributes Category="urn:oasis:names:tc:xacml:3.0:attribute-category:action">
      <Attribute AttributeId="urn:oasis:names:tc:xacml:1.0:action:action-id" IncludeInResult="false">
         <AttributeValue DataType="http://www.w3.org/2001/XMLSchema#string">update</AttributeValue>
      </Attribute>
   </Attributes>
   <Attributes Category="urn:oasis:names:tc:xacml:1.0:subject-category:access-subject">
      <Attribute AttributeId="http://wso2.org/claims/role" IncludeInResult="false">
         <AttributeValue DataType="http://www.w3.org/2001/XMLSchema#string">doctor</AttributeValue>
      </Attribute>
   </Attributes>
   <Attributes Category="urn:oasis:names:tc:xacml:3.0:attribute-category:resource">
      <Attribute AttributeId="urn:oasis:names:tc:xacml:1.0:resource:resource-id" IncludeInResult="false">
         <AttributeValue DataType="http://www.w3.org/2001/XMLSchema#string">MedicalRecords</AttributeValue>
      </Attribute>
   </Attributes>
</Request>

XAML值中的

与AttributeId匹配，您必须使用相同的AttributeId。但是您在请求中使用了urn:oasis:names:tc:xacml:1.0:subject:subject-id作为AttributeId
