  • 1.  how response code will work in dp:url-open

    Posted 05/27/25 02:49 AM

    Dears,

    I am using dp:url-open in my XSLT to call MQ and ACE. However, one thing is not clear to me regarding setting a response.

    response="xml | binaryNode | ignore | responsecode | responsecode-binary | responsecode-ignore"

    If set response ="responsecode" as below, and if I receive 500 or any other from the target URL, will the flow be stopped or continue?

    <dp:url-open target="URL" response="responsecode"

    </dp:url-open>

    The exception in this case will be reported on system log but processing will continue.

    Kumar,
    You must check the response code from the returned nodeset and issue the apigw:reject to stop processing if that is your requirement.

    HI Kumar, 

    if the response code returned as 500, it will not stop the process.
    However you can log the report and stop the process by following the code:
     
    <dp:variable name="responsecode" />
    <dp:url-open target="http://example.com/api" response="responsecode">
        <!-- Request setup if needed -->
    </dp:url-open>
     
    <!-- Check the response code -->
    <xsl:if test="$responsecode = 500">
        <!-- Log the error -->
        <dp:log level="error" category="apigw" xmlns:dp="http://www.datapower.com/extensions">
            HTTP 500 error received from http://example.com/api
        </dp:log>
     
        <!-- Raise a fault to stop processing -->
        <dp:raise-fault
            name="HTTP500Error"
            xmlns:dp="http://www.datapower.com/extensions"
            description="Remote server returned HTTP 500 - Internal Server Error"/>
    </xsl:if>
     
    <!-- Continue with processing only if not error -->
     
     
    If you want to play with the response code then you can use xsl:choose like below
    <dp:variable name="responsecode" />
    <dp:url-open target="http://example.com/api" response="responsecode">
        <!-- Request setup if needed -->
    </dp:url-open>
     
    <!-- Check if response is 500 -->
    <xsl:choose>
        <xsl:when test="$responsecode = 500">
            <!-- Log error -->
            <!-- Raise fault and exit -->
            <dp:raise-fault
                name="HTTP500Error"
                xmlns:dp="http://www.datapower.com/extensions"
                description="Remote server returned HTTP 500 - Internal Server Error"/>
        </xsl:when>
     
        <xsl:otherwise>
            <!-- Response is NOT 500: continue processing -->
            <!-- Continue with your processing -->
            <!-- e.g., transform, route, or respond -->
        </xsl:otherwise>
    </xsl:choose>
