（MODS：我查過我相似的其他線程，但這個問題是在更深的層次）騾子ESB：不能將傳入的JSON對象，通過「選擇」節點
我轉換一個Hello World流向接受JSON對象的流，我試圖使用'Choice'流控制節點將它路由到兩個'Set Payload'節點之一。
我的問題是我能得到的流量選擇節點路由到正確的目的地節點
（我懷疑這是一個JSON問題）
下面是我的流程
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns:json="http://www.mulesoft.org/schema/mule/json" version="EE-3.5.0" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:core="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.mulesoft.org/schema/mule/http http://www.mulesoft.org/schema/mule/http/current/mule-http.xsd

<otherwise>
<set-payload value="#['Default case, uid: ' + payload.uid + ', payload: ' + payload]" doc:name="Set Payload"/>
</otherwise>
</choice>
</flow>
</mule>
我正在發送以下JSON字符串流
{ "uid" : "ABC" }
所以流量應該能夠檢測到UID等於「ABC」
下面是我的測試程序

正如你所看到的，我送「ABC」的UID，但它還是到默認情況
，你可以在流中看到的，我打印出「設置有效載荷」節點相關的有效載荷信息：
＃[「默認情況下，UID：」 + payload.uid +」，有效載荷： '+有效載荷]
......，正如你可以從測試程序我從該聲明以下輸出看到：
Default case, uid: null, payload: org.apache.commons.httpclient.ContentLengthI
[email protected]
2個問題
我怎樣才能解決這個，所以我可以打「ABC '路線？

我知道它的輸入流，但如果是數據？
感謝
