Execute same scenario with multiple multiple specific authorizationHeaders

[Craz1Cadr1ca]

Hi guys, 

I wrote very simple scenario, 

package placeBet


import scala.concurrent.duration._


import io.gatling.core.Predef._
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._


class placeBet extends Simulation {


 val httpProtocol = http
 .baseURL("http://localhost:49815")
 .proxy(Proxy("localhost", 49815).httpsPort(49815))
 .inferHtmlResources()
 .acceptHeader("*/*")
 .authorizationHeader("Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJQbGF5ZXJJZCI6IjQ5MzE0NTQiLCJTZXNzaW9uSWQiOiIzZWNmOGQyMS04NjVhLTQ1OTQtOGQyZS00MDBhNjU4YTAwOWMiLCJTaXRlSWQiOiIxIiwibmJmIjoxNTA3NjQ4Njc0LCJleHAiOjE1MDgyNTM0NzQsImlhdCI6MTUwNzY0ODY3NH0.j3ID6egSwaFcQ-u8Sa8Qu40fNPAJIA7GWFoSBhBV98U")
 .contentTypeHeader("application/json")


 val headers_1 = Map(
 "Postman-Token" -> "cdc4e6fc-4198-41c6-bf0d-3b7b51a99d6b",
 "accept-encoding" -> "gzip, deflate",
 "cache-control" -> "no-cache",
 "content-length" -> "242")


 val scn = scenario("placeBet")
 .exec(http("request_1")
 .post("/betting/placeBets")
 .headers(headers_1))


 setUp(
   scn.inject(
 nothingFor(4 seconds), // 1
 atOnceUsers(10), // 2
 rampUsers(10) over(5 seconds), // 3
 constantUsersPerSec(20) during(15 seconds), // 4
 constantUsersPerSec(20) during(15 seconds) randomized, // 5
 rampUsersPerSec(10) to 20 during(10 minutes), // 6
 rampUsersPerSec(10) to 20 during(10 minutes) randomized, // 7
 splitUsers(1000) into(rampUsers(10) over(10 seconds)) separatedBy(10 seconds), // 8
 splitUsers(1000) into(rampUsers(10) over(10 seconds)) separatedBy atOnceUsers(30), // 9
 heavisideUsers(1000) over(20 seconds) // 10
   ).protocols(httpProtocol)
 )
}

but now the business from me whats to execute this scenario with multiple different users ( a.k.a different tokens in authorizationHeader), I've searched in the internet and I couldn't find anything helpful.

Do you know how to do this without multiplying the scenario itself?
