如何獲得WSO2 balana的義務

Question

我一直在使用WSO2 balana樣本，並且遇到了代碼以從XACML響應中獲取建議。

StringBuilder Advice = new StringBuilder(); 
       List<Advice> advices = result.getAdvices(); 
       for(Advice advice : advices){ 
        List<AttributeAssignment> assignments = advice.getAssignments(); 
        for(AttributeAssignment assignment : assignments){ 
         Advice.append("Advice : " + assignment.getContent() +"\n\n"); 
        } 
       } 
       obj1.Advice = Advice.toString(); 

以同樣的方式，我想取的義務，我該怎麼辦呢？

Answer 1

是的..你可以做到這一點。但在這裏，您需要將您的義務結果對象轉換爲相關義務類型（XACML 2或XACML 3）。你可以在那裏做一些「instanceof」檢查。當

  List<ObligationResult> obligations = result.getObligations(); 
      for(ObligationResult obligation : obligations){ 
       if(obligation instanceof org.wso2.balana.xacml3.Obligation){ 
        List<AttributeAssignment> assignments = ((org.wso2.balana.xacml3.Obligation)obligation).getAssignments(); 
        for(AttributeAssignment assignment : assignments){ 
         System.out.println("Obligation : " + assignment.getContent() +"\n\n"); 
        } 
       } 
      }
