用騾子發送HTTP參數使用輪詢

Question

第一次使用Mule。我有下面列出的流量，它正在嘗試每15秒將參數發佈到URL。

我搜集的URL參數必須被定義爲有效載荷，像

Mule ESB - How to call a API via HTTP POST method (sending parameters along)

<set-payload value="#[['xxx':'yyy']]"/> 

，但我無法找出如下使用輪詢元素時把這個， 。我在它當前位置得到的錯誤是

找到的元素'poll'開始的內容無效。

我已經在民意調查之前嘗試過，內部和http：outbound-endpoint。有任何想法嗎？

感謝 奧利弗

Answer 1

您需要出站端點前設置有效載荷。然而，輪詢僅節選一個消息處理器，以便他們需要鞋有角的使用processor-chain或sub-flow或類似：

<poll doc:name="Poll"> 
      <fixed-frequency-scheduler frequency="15" 
       timeUnit="SECONDS" /> 
      <processor-chain> 
       <set-payload value="#[['xxx':'yyy']]" /> 
       <http:outbound-endpoint exchange-pattern="request-response" 
        method="POST" address="http://myurl.com" doc:name="HTTP" 
        transformer-refs="Message_Properties"> 
       </http:outbound-endpoint> 
      </processor-chain> 
     </poll>
