Wso2 Identity Server是否通过JSON支持MDP？

我有一个XML XACML请求，其中包含多个决策概要文件（MDP）元素——同一类型的多个类别，以及可选的MultipleRequest元素。 此请求在Wso2 IS 5.3.0中正常工作

但是，如果我尝试以JSON形式重写此请求，对应于XACML JSON概要文件，WSO2将无法按预期处理它：

• 若我使用多请求对象，服务器返回错误（40020）“请求解析异常”
• 若我只是将几个类别对象枚举为数组，而并没有显式的MultiRequest，那个么服务器在这些类别中找不到任何属性值

使用wso2is 5.3.0正确处理JSON中的单个决策请求

wso2is的这种行为是由于当前的设计限制，还是我编写了一个错误的JSON MDP请求

我的XML XACML请求（具有显式多请求的情况）：

根据你的测试，简短的回答是不，不是

我针对测试了您的XACML请求，效果很好。以下是JSON格式的响应：
