Question

我试图通过wso2 esb序列从wso2数据服务获取一些数据，如下所示

<sequence xmlns="http://ws.apache.org/ns/synapse" name="ConcurGetSAEExtractFlow">
   <log level="custom">
      <property name="Debugging" value="ConcurGetSAEExtractFlow" />
   </log>
   <xslt key="GetConcurSAE_Extract_Transformation" />
   <property name="post-data-service-sequence" value="ConcurTransformSAEExtractFlow" />
   <property name="OUT_ONLY" value="false" />
   <send receive="DataServiceInvocationErrorFlow">
      <endpoint key="ConcurDataServiceEndpoint" />
   </send>
   <description />
</sequence>

xslt转换GetConcurSAE_Extract_Transformation如下

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dat="http://ws.wso2.org/dataservice" xmlns:fn="http://www.w3.org/2005/02/xpath-functions" version="1.0">
    <xsl:template match="/">
        <xsl:element name="dat:GetConcurSAEExtract">            
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

如图所示，没有提供服务和输出映射的输入映射。我已经在wso2 dss“尝试此服务”中测试了该服务，它运行良好。但是当我试图通过代理运行wso2 esb时，我会收到以下错误块

我无法找出导致此类错误的错误。如果有人对此有所了解。

您没有使用XSLT复制soap信封和标题。在<log level="full"/>来电之前和之后进行一次<xslt>，然后您会看到您的XSLT也会获得<soap:envelope><soap:body>...

所以你必须把它放在输出中。

伪代码：

<xsl:template match="envelope|body">
    <xsl:copy>
        <xsl:apply-templates/>
    </xsl:copy/>
</xsl:template>
