Service Virtualization

DevTest Version - 10.1

I need to add an authorization header to a live invocation. So far, I've tried adding it to lisa.vse.request with a scriptable data protocol and added it to lisa.vse.http.current.transaction using a groovy script. In both cases, you can see that the header is added, but the live invocation step fails to pick up the authorization header. Is there another way to add in a header?

For reference, the scriptable data protocol is:

%groovy%

import com.itko.util.ParameterList;
import com.itko.util.Parameter;

ParameterList metadata = lisa_vse_request.getMetaData();
metadata.addParameter(new Parameter("Authorization", "Basic Password="));

lisa_vse_request.setMetaData(metadata);

The groovy script to set lisa.vse.http.current.transaction is:

import com.itko.util.ParameterList;

ParameterList metadata = testExec.getStateValue("lisa.vse.http.current.transaction").getRequestHeaders();
metadata.put("Authorization", "Basic Password=");

Did you try checking the option "Do not modify host header parameter received from client" in the Live Invocation step?

Prema,

Thanks, but I need to add an authorization header for the live invocation. It doesn't come in with the request.

As far as I can tell, the request object used in the Live Invocation step is immutable with the exception of headers added by the DevTest framework (per Prema's post).

This may require a custom approach whereby Live Invocation is replaced with a REST or WS Exec XML step. But, that means marshaling and unmarshaling data into the lisa_vse_response object so the Responder step can deal with it.

I’ve been working on calling the live service with a ws exec step, then marshaling the lisa.vse.response. Everything looked ok to me, but the responder step would exit without sending a reply. I added a prepare response step, but now it’s throwing an odd XML error from the responder –

If you have a few minutes to take a look at this, I could use some suggestions.

Thanks for your help

Hi Brian,

lisa.vse.response should be in Transient form. Did you set the Web Service step response to lisa.vse.response and made it Transient?

Could you open a support ticket and we can look into the issue in a WebEx?

Thanks,

Prema

I checked the raw SOAP request and web service execution step. The only place I've found to store the response is the utility filter to store the step response as a property. Is there a different step or filter to try?

You can store the Web service step response to a property. Then you have to convert the response to transient form and save it to lisa.vse.response and the HTTP Rsponder should return the response properly.
