WSO2。如何在XML中轉換SOAP消息並將其發送到服務？

Question

美好的一天！

最近，我開始學習WSO ESB

我的服務接收請求，並以XML格式的響應，例如：

<!--The query in my service --> 
POST/HTTP/1.1 
Content-Type: text/xml; charset=utf-8 
Content-Length: 109  
<req> 
    <Value>How are you?</Value> 
</req> 

<!--The response from the service --> 
HTTP/1.1 200 OK 
Content-Length: 120 
Content-Type: text/xml; charset=utf-8  
<res> 
<Value>Very good!!!</Value> 
</res> 

我需要通過代理從客戶端轉換SOAP請求SOAP客戶端中的XML服務的示例

示例SOAP請求和代理服務中的響應

<!--The request from the client to proxy service--> 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <soap:Body> 
    <Question xmlns="http://MyTestService"> 
     <Value>How are you?</Value> 
    </Question> 
    </soap:Body> 
</soap:Envelope> 

<!--Answer the service proxy to the client--> 
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> 
    <s:Body> 
    <QuestionResponse xmlns="http://CyberPlatService"> 
     <Fun1Result>Very good!!!</Fun1Result> 
    </QuestionResponse> 
    </s:Body> 
</s:Envelope> 

這裏是我的代理服務

<proxy xmlns="http://ws.apache.org/ns/synapse" name="CyberPlatProxy" transports="https http" 
     startOnLoad="true" trace="disable"> 
    <target> 
    <inSequence> 
     <payloadFactory media-type="xml"> 
     <format> 
      <req> 
      <Value>$1</Value> 
      </req> 
     </format> 
     <args> 
      <arg xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
      expression="//Question/Value"/> 
     </args> 
     </payloadFactory> 
     <property name="messageType" value="text/xml" scope="axis2" type="STRING"/> 
     <property name="DISABLE_CHUNKING" value="true" scope="axis2" type="STRING"/> 
     <log level="custom"/> 
     <send> 
     <endpoint> 
      <http method="post" uri-template="http://localhost:2009/"/> 
     </endpoint> 
     </send> 
    </inSequence> 
    <outSequence> 
     <payloadFactory media-type="xml" description="res"> 
     <format> 
      <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> 
      <s:Body> 
       <GetStaysResponse xmlns="http://CyberPlatService"> 
       <GetStaysResult>$1</GetStaysResult> 
       </GetStaysResponse> 
      </s:Body> 
      </s:Envelope> 
     </format> 
     <args> 
      <arg expression="//Value"/> 
     </args> 
     </payloadFactory> 
     <property name="messageType" value="application/soap+xml" scope="axis2" type="STRING"/> 
     <send/> 
    </outSequence> 
    <faultSequence/> 
    </target> 
</proxy> 

什麼也沒有發生，我究竟做錯了什麼？

的 「問題」 節點屬於http://MyTestService空間中，因此，您的XPath //Question/Value不能工作，你應該改變：

<arg xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" expression="//Question/Value"/> 

到：

<arg xmlns:test="http://MyTestService" expression="//test:Question/test:Value/text()"/>
