Solved: Extract Variable : Xpath for Soap request not work... - Page 2

Report Inappropriate Content · 12-05-2017 11:09 PM

I created one soap pass through proxy and the default Extract Operation name policy is not working when deployed on our on-premise private cloud. The same proxy is resolving the xpath functions in our public cloud instance.

On Premise private cloud version - 4.17.09.00

Any help appreciated .

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="Extract-Operation-Name">
    <DisplayName>Extract Operation Name</DisplayName>
    <Properties/>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
    <Source clearPayload="false">request</Source>
    <XMLPayload stopPayloadProcessing="false">
        <Variable name="envelope" type="String">
            <XPath>local-name(/*)</XPath>
        </Variable>
        <Variable name="body" type="String">
            <XPath>local-name(/*/*[local-name() = 'Body'])</XPath>
        </Variable>
        <Variable name="envelopeNamespace" type="String">
            <XPath>namespace-uri(/*)</XPath>
        </Variable>
        <Variable name="operation" type="String">
            <XPath>local-name(//*[local-name() = 'Body']/*[1])</XPath>
        </Variable>
    </XMLPayload>
</ExtractVariables>

ok thanks.

From the screenshots, here is what I see. In the request you are sending to the API Proxy running on Edge SaaS :

you are using POST.
SOAP is being sent into the Apigee Edge API Proxy
You are running the ExtractVariables on the SOAP provided
the ExtractVariables is working as expected.

In the request sent to the API Proxy for othe customer-managed (aka on-prem) Edge install

You are using GET
No payload is sent (because it's a GET request)
The ExtractVariables is doing nothing. This is expected, correct behavior, because the payload is empty!

Somehow there is a difference between the request you are making to the Edge SaaS and the request you are sending to the customer-managed installation of Edge.

Resolve that difference, and I bet you'll solve your mystery!
