Hi Gatling team,
Here is my issue:
I use Gatling Expression Language with a body that I have in a file. The problem is that I need to encrypt it before sending it. Of course I want it to be encrypted AFTER Gatling replaces ${} values !
The SignatureCalculator doesn’t expose the body as a mutable variable inside the request and I don’t think there’s an easy way to change it (and I don’t really want to use gatling internals).
The only solution I got so far is :
val resolvedBody: Expression[String] = session => {
val newSession: Session = session.set(“foo”, “bar”).set(“fooz”, “baz”)
val myString = “${foo} and ${fooz}”.el[String]
myString(newSession).map(encryptAsString)
}
val request = exec(http(“Request name”)
.get(“url”)
.body(StringBody(resolvedBody))
)
(of course, the session will be filled with a feeder, and the myString will be the file content)
The problem with this solution is that I have to load all the files myself as string before the simulation.
Do you have an idea to perform what I want in a better way ?
Thanks in advance !
