我想添加一个策略集,以便使用目标依次运行一系列策略,该目标根据输入字段“resource”定义给定策略是否适用。为了开始测试,我编写了一个包含一个策略的policySet。
WSO2 PAP的评估未能显示“NotApplicable”的结果,而我希望收到“许可证”。
这里以XML格式创建名为“cfatest0”的策略:

低于PAP下的WSO2“Try-It”工具生成的请求:
<Request xmlns="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17" CombinedDecision="false" ReturnPolicyIdList="false">
<Attributes Category="urn:oasis:names:tc:xacml:1.0:subject-category:access-subject">
<Attribute AttributeId="urn:oasis:names:tc:xacml:1.0:subject:subject-id" IncludeInResult="false">
<AttributeValue DataType="http://www.w3.org/2001/XMLSchema#string">claudef@br.red.com</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">TPS_AE_REST_Policy</AttributeValue>
</Attribute>
</Attributes>
</Request>
决定是:NotApplicable
我是否会错过使用方式向PolicySet发送请求的方式?使用WSO2高级策略编辑器时,我在响应时得到相同的错误。在测试PAP“Try-It”工具中隔离的策略时,我会收到正确的值,对于此策略,该值为:“Permit”。
