Mule 3.1.2のProxy HTTP POSTフォームデータ

Question

いくつかの投稿データをmule 3.1.2の別のサーバに送信する必要があります。ここに私のミュール設定ファイルがあります：

私はhttp://localhost:5678/httpHelloへの投稿要求を行い、いくつかのパラメータを送信します。 http://localhost:8080/webproj/index.jspページでは、受信したパラメータを調べますが、パラメータは空です。 index.jspページの最初に送信されたパラメータを受け取って、mule-configファイルを変更する方法を教えてください。どうもありがとう！

application/x-www-form-urlencodedがであると仮定すると、ここでは必要なことを行う設定が行われます（つまり、ペイロードを記録してプレゼンスに基づいて別の応答を選択するパラメータ：of

<flow name="webFormFlow"> 
    <!-- Accept a http request from the specific address --> 
    <http:inbound-endpoint address="http://localhost:5678/httpHello"> 
     <http:body-to-parameter-map-transformer /> 
    </http:inbound-endpoint> 

    <!-- This logger is just set to show the message accepted from the request --> 
    <logger level="INFO" message="#[payload]" /> 

    <choice> 
     <when expression="payload.size() &gt; 0" evaluator="groovy"> 
      <http:outbound-endpoint address="http://localhost:8080/webproj/index.jsp" 
       method="POST" contentType="application/x-www-form-urlencoded" /> 
     </when> 
     <otherwise> 
      <message-properties-transformer> 
       <add-message-property key="Content-Type" value="text/plain" /> 
      </message-properties-transformer> 
      <expression-transformer> 
       <return-argument expression="no parameter is given!" 
        evaluator="string" /> 
      </expression-transformer> 
     </otherwise> 
    </choice> 
</flow>
