WSO2中JSON有效负载的base64编码

如何解决WSO2中JSON有效负载的base64编码

我试图做一个POC，以便在WSO2中将json有效负载编码为base64格式。我已经使用有效负载工厂来形成一个json有效负载，如下所示：

}

现在，我已使用以下代码行对上述有效负载进行base64编码。

<property name="FinalEncodedResponse" scope="default" expression="base64Encode($body)"/>

上面的行对数据进行编码，但是当我解码时，它显示如下（仅包含值），而不是我在上面指定的实际json。

我想知道我们如何像在WSO2中一样将json有效负载编码为base64格式？需要帮助。

解决方法

您可以尝试以下方法吗？

 <property expression="json-eval($)" name="messageBody" scope="default"/>
 <property expression="base64Encode(get-property('messageBody'))"
                  name="FinalEncodedResponse"/>
