http - 骡子 - 找不到变量

Question

我正在尝试从 GET http 请求中检索一些变量，例如

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

使用这个流程

<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>  

这是xslt样式表

<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>    

但是当我运行流程时，出现以下错误:

它给出一个 null 而不是通过 http 传递的值。

有什么想法吗？？

Answer 1

使用以下 http 入站。

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

这应该符合您的要求

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