在WSO2自定義處理程序中以語法方式獲取HTTP_SC

Question

如何在WSO2自定義中介程序中獲取HTTP_SC？

我嘗試下面的代碼：

@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; 
} 

下面是序列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> 

以下是結果的日誌文件

INFO {org.apache.synapse.mediators.builtin.LogMediator} - TRY_LOG_IT = 200

正如你所看到的，日誌調解器從axis2上下文（來自日誌的第一行）記錄了HTTP_SC，但它沒有出現在m我的調解員內有一些屬性。

我找到了一種解決方法，通過使用屬性中介將MY_HTTP_SC設置爲axis2的值：HTTP_SC，並在我的介體中使用MY_HTTP_SC，但不知道爲什麼當我直接嘗試訪問HTTP_SC時不起作用。

<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位於axis2消息上下文中。所以你需要像下面這樣訪問Axis2消息上下文：

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