Need help on Parameterization in Gatling!!

Hi Team,

I am a starter on Gatling.
I have configured and written a few basic Scala files with Simulations using
.setUp. I have the below problem to overcome.

I have Webservice requests which are having lengthy bodies so i am passing body from resources.
Ex: .body(RawFileBody(“mobileapp/serviceRequest.dat”))).
If i want to parameterize few things in webservice body i.e in request.dat, i couldn’t figure out how.

Thanks in advance,

Have you read the official documentation or joined the Gatling Academy?
