WSO2 身份服务器 XACML PAP 和义务

Question

按照 OASIS XACML 版本 3 语法说明中所述，使用 WSO2 XML Web 编辑器将一组义务添加到现有 XACML 策略时，WSO2 编辑器抛出以下错误：

Entitlement policy is not updated. Error is :Invalid Entitlement Policy. Policy is not valid according to XACML schema

以下语句位于策略定义末尾的标记之前，请参阅添加的行：

其他，符合第 3 版的语法也会引发相同的错误。是否需要任何进一步的配置，一些 .xml 或模式文件调整，以使编辑器将 Obligation 语句识别为有效语法？这是 WSO2 IS 版本 5。

更新： 语句错误：

<Obligations>
  <Obligation ObligationId="send-email" FulfillOn="Deny">
    <AttributeAssignment AttributeId="email" DataType="http://www.w3.org/2001/XMLSchema#string">myid@red.com</AttributeAssignment>
  </Obligation>
</Obligations>

更新： 在更正 Obligations 语句的语法后，您可以在下面找到有效的 XACML V3 兼容策略：

Answer 1

在查看了OASIS XACML version 3 的手册后，我发现这个错误是由于缺少语法一致性引起的。我已将语句更新为最新规范，我的非常简单的示例（如下所示）开始执行，向结果添加一个带有注释字符串的属性。

下面是一个代码示例：

  <ObligationExpressions>
      <ObligationExpression FulfillOn="Permit" ObligationId="citycheck">
         <AttributeAssignmentExpression AttributeId="urn:oasis:names:tc:xacml:3.0:example:attribute:text">
            <AttributeValue DataType="http://www.w3.org/2001/XMLSchema#string">The validation passed sucessfully</AttributeValue>
         </AttributeAssignmentExpression>
      </ObligationExpression>
   </ObligationExpressions>

下面是从 WSO2 "Try It" 控制台复制的结果：

                     <Response xmlns="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17">
<Result>
<Decision>Permit</Decision>
<Status>
<StatusCode Value="urn:oasis:names:tc:xacml:1.0:status:ok"/>
</Status>
<Obligations>
<Obligation ObligationId="citycheck">
<AttributeAssignment  AttributeId="urn:oasis:names:tc:xacml:3.0:example:attribute:text" DataType="http://www.w3.org/2001/XMLSchema#string">
The validation passed successfully</AttributeAssignment>
</Obligation>
</Obligations>
<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="true">
<AttributeValue DataType="http://www.w3.org/2001/XMLSchema#string">ldap</AttributeValue>
</Attribute>
</Attributes>
