如何在Mule ESB中通過UDP傳輸獲取客戶端IP？

Question

我試圖得到一個UDP包的客戶端IP和插座，並使用MEL代碼

#[message.inboundProperties.MULE_REMOTE_CLIENT_ADDRESS] 

但是這個變量總是空，我已經能夠使它發揮它保存在一個Flowvar變量在TCP傳輸上，有沒有人知道如何獲得UDP中的遠程客戶端地址？

這是我的XML文件：

<mule xmlns:metadata="http://www.mulesoft.org/schema/mule/metadata" xmlns:udp="http://www.mulesoft.org/schema/mule/udp" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

<set-payload value="#[flowVars.source] dice #[payload]" doc:name="Set Payload"/> 
<echo-component doc:name="Echo"/> 
</flow> 
</mule> 

更新： 我解決地址問題與MEL代碼

#[message.inboundProperties['packet.address']]: #[message.inboundProperties['packet.port']] 

感謝David Dossot對他的幫助。

用途：

#[message.inboundProperties['packet.address']]
