Extract URL Variable

[#1]

Hi, My proxy base path is: /example/v1

My URI is : /example/v1/type

I need to extract the type how to give my pattern in extract variable policy.

My extract variable policy is:

<URIPath>
        <Pattern ignoreCase="true">/{type}</Pattern>
</URIPath>

That looks pretty close to me. I've just done the same. Here's my example policy:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="ExtractType">
    <DisplayName>ExtractType</DisplayName>
    <Properties/>
    <URIPath name="type">
        <Pattern>/{type}</Pattern>
    </URIPath>
</ExtractVariables>

Did it work?

[gsjurseth]

Yes, it worked perfectly with the policy I posted above. I was able pull the type variable and apply it later by adding a new header with the AssignMessage policy.

But It doesn't works for me. Can you share your API Bundle

Have you checked it inside a flow. Inside the flow, it is not working.

Check in flow with where the condition is defined like

<Condition>(proxy.pathsuffix MatchesPath "/account/{id}") and (request.verb = "GET")</Condition>

The Extract variable policy on flow request

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="Extract-Variables-1">
    <DisplayName>Extract Variables-1</DisplayName>
    <URIPath>
        <Pattern ignoreCase="true">/account/{id}</Pattern>
    </URIPath>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
    <Source clearPayload="false">request</Source>
</ExtractVariables>

works fine.
