騾子 - 變量未發現

Question

我試圖用這個流程

<flow name="SOAPWebService" > 

    <http:inbound-endpoint address="http://localhost:8088/" exchange-pattern="request-response">   
    </http:inbound-endpoint> 

    <set-variable value="#[message.inboundProperties['id']]" variableName="paramId"></set-variable> 
    <set-variable value="#[message.inboundProperties['type']]" variableName="paramType"></set-variable> 

    <component class="com.example.components.SampleComponent" ></component> 

    <mule-xml:xslt-transformer 
     maxIdleTransformers="2" maxActiveTransformers="5" 
     xsl-file="C:\WorkSpace\MyProject\src\main\resources\xslt\PrepareRequestXML.xsl"> 
     <mule-xml:context-property key="paramId" 
      value="#[flowVars['paramId']]" /> 
     <mule-xml:context-property key="paramType" 
      value="#[flowVars['paramType']]" /> 
    </mule-xml:xslt-transformer> 

    <cxf:proxy-client payload="body" 
     enableMuleSoapHeaders="true">   
    </cxf:proxy-client> 
    <http:outbound-endpoint exchange-pattern="request-response" 
     address="http://localhost:8080/ClientsDB/douane" doc:name="HTTP"> 
    </http:outbound-endpoint> 

    <byte-array-to-string-transformer doc:name="Byte Array to String" />  
    <file:outbound-endpoint ....... .. /> 
</flow> 

這裏找回從GET HTTP請求的一些變量，如

http://localhost:8088/?id=xxx&type=yyyy 

是XSLT樣式表

<xsl:stylesheet version="2.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:wsd="http://wsdouane/"> 
    <xsl:output method="xml" indent="yes" /> 
    <xsl:param name="paramType"></xsl:param> 
    <xsl:param name="paramId"></xsl:param> 

    <xsl:template match="*" > 
     <xsl:element name="wsd:find" namespace="http://wsdouane/"> 
     <xsl:element name="entity"> 
     <xsl:element name="id"> 
      <xsl:value-of select="$paramId"/> 
     </xsl:element> 
     <xsl:element name="type"> 
      <xsl:value-of select="$paramType"/> 
     </xsl:element> 
     </xsl:element>   
     </xsl:element> 
    </xsl:template> 

    <xsl:template match="text()|processing-instruction()|comment()"> 
     <xsl:copy> 
      <xsl:apply-templates select="@*|node()" /> 
     </xsl:copy> 
    </xsl:template> 
</xsl:stylesheet>  

但是當我運行流程時出現以下錯誤：

它給出一個空值而不是通過http傳遞的值。

任何想法？

Answer 1

使用以下http入站。

<http:inbound-endpoint address="http://localhost:8088" exchange-pattern="request-response">   
</http:inbound-endpoint> 

這應該與你的

http://localhost:8088/?id=xxx&type=yyyy
