Is it possible to parse an environmental variable as a response for a REST API?-CodePudding

I have a REST API created on integration studio, I send back a response using the following tag:

 <format> "Some response" </format>

Is is possible to set an environmental variable as the response? So that I can change my response without having to redeploy the API.

CodePudding user response：

You can use the get-property expression in the Payload factory to read the response from an environment variable as follows,

<payloadFactory media-type="text">
    <format>"$1"</format>
    <args>
        <arg evaluator="xml" expression="get-property('env', 'property_name')"/>
    </args>
</payloadFactory>

Depending on your requirement you may need to change the media-type as well.
