如何在WSO2自定义中介内获取HTTP_SC？

我正在尝试以下代码：

@Override
public boolean mediate(MessageContext context)
{
    Log log = LogFactory.getLog(InfaAccessLogMediator.class);

    Map<String,Object> axis2Properties = ((Axis2MessageContext)context).getAxis2MessageContext().getProperties();

    for (String prop : axis2Properties.keySet()) {
        log.info(String.format("AXIS2 Property: %s", prop));
    }

    return true;
}

以下是序列XML：

<sequence name="WSO2AM--Ext--Out" xmlns="http://ws.apache.org/ns/synapse">
<log level="custom">
    <property name="TRY_LOG_IT" expression="get-property('axis2','HTTP_SC')" />
</log>
<class name="com.informatica.apimanager.wso2_plugins.InfaAccessLogMediator"/>

</sequence>

以下是日志文件中的结果

如您所见，日志介体从axis2上下文（日志的第一行）记录了HTTP_SC，但它没有出现在我的介体内的属性映射中。

我找到的解决方法是使用属性介体将MY_HTTP_SC设置为axis2的值：HTTP_SC并在我的介体中使用MY_HTTP_SC，但不确定为什么当我直接尝试访问HTTP_SC时这不起作用。

<property name="MY_HTTP_SC" action="set" expression="get-property('axis2','HTTP_SC')" />
<class name="com.informatica.apimanager.wso2_plugins.InfaAccessLogMediator"/>

Answer 1

HTTP_SC位于axis2消息上下文中。因此，您需要访问Axis2消息上下文，如下所示：

Map<String,Object> axis2Properties = ((Axis2MessageContext)context).getAxis2MessageContext().getProperties();

在WSO2自定义处理程序中以语法方式获取HTTP_SC
