Gatling & Scala : How to split values in loop? - scala

Question

I want to split some values in loop. I used split method in check and it works for me. But, there are more than 25 values of two different types.
So, I am implementing loop in scala and struggling.
Consider the following scenario:
import scala.concurrent.duration._
import io.gatling.core.Predef._
import io.gatling.http.Predef._
class testSimulation extends Simulation {
val httpProtocol = http
.baseURL("https://website.com")
.doNotTrackHeader("1")
.disableCaching
val uri1 = "https://website.com"
val scn = scenario("EditAttribute")
.exec(http("LogIn")
.post(uri1 + "/web/guest/")
.headers(headers_0)
.exec(http("getPopupData")
.post("/website/getPopupData")
.check(jsonPath("$.data[0].pid").transform(_.split('#').toSeq).saveAs("pID"))) // Saving splited value
.exec(http("Listing")
.post("/website/listing")
.check(jsonPath("$.data[*].AdId").findAll.saveAs("aID")) // All values are collected in vector
// .check(jsonPath("$.data[*].AdId").transform(_.split('#').toSeq).saveAs("aID")) // Split method Not working for batch
// .check(jsonPath("$.data[*].AdId").findAll.saveAs("aID")) // To verify the length of array (vector)
.check(jsonPath("$.data[0].RcId").findAll.saveAs("rID")))
.exec(http("UpdatedDataListing")
.post("/website/search")
.formParam("entityTypeId", "${pId(0)}") // passing splited value, perfectly done
.formParam("action_id", "${aId(0)},${aId(1)},${aId(2)},..and so on) // need to pass splitted values which is not happening
.formParam("userId", "${rID}")
// To verify values on console (What value I m getting after splitting)...
.exec( session => {
val abc = session("pID").as[Seq[String]]
val xyz = session("aID").as[Seq[String]]
println("Separated pId ===> " +abc(0)) // output - first splitted value
println("Separated pId ===> " +abc(1)) // split separater
println("Separated pId ===> " +abc(2)) // second splitted value
println("Length ===> " +abc.length) // output - 3
println("Length ===> " +xyz.length) // output - 25
session
}
)
.exec(http("logOut")
.get("https://" + uri1 + "/logout")
.headers(headers_0))
setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
}
I want to implement a loop which performs splitting of all (25) values in session. I do not want to do hard coding.
I am newbie to scala and Gatling as well.

Since it is a session function the below snippet will give a direction to continue ,use split just like you do in Java :-
exec { session =>
var requestIdValue = new scala.util.Random().nextInt(Integer.MAX_VALUE).toString();
var length = jobsQue.length
try {
var reportElement = jobsQue.pop()
jobData = reportElement.getData;
xml = Configuration.XML.replaceAll("requestIdValue", requestIdValue);
println(s"For Request Id : $requestIdValue .Data Value from feeder is : $jobData Current size of jobsQue : $length");
} catch {
case e: NoSuchElementException => print("Erorr")
}
session.setAll(
"xmlRequest" -> xml)
}
