Issue when trying to pass parameter from response to header of next service

Gatling (Open-Source)

Facing issue while trying to pass parameter from first request to the header of the next. Could someone please let me know what am I doing wrong here?

Code:

`
package computerdatabase

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._

class Test1 extends Simulation {

val httpProtocol = http.baseUrl(“https://tabc.com”)

val httpProtocol_1 = http.baseUrl(“https://services.com”)

val header = Map(
“Content-Type” → “application/soap+xml;charset=UTF-8”,
“Connection” → “alive”,
“User-agent” → “Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0”)

val header_1 = Map(
“Authorization”->"${authToken}",
“actor”->“ISET”,
“log_token”->“LOG”,
“scope”->“read”,
“timestamp”->“123456789”
)

object pl{
val layer7 = scenario(“getauth”).exec(http(“GetAuthToken”)
.post("/oauth/token")
.body(StringBody("""{“client_id” : “123456”,
“client_secret” : “abc123456”,
“grant_type” : “client_credentials”}
“”")).asJSON.check(status.is(200)).check(jsonPath("$.access_token").saveAs(“authToken”)))

val pl1 = exec(http(“dental”)
.post("/dental/search")
.headers(header_1)
.body(StringBody("""<?xml version="1.0" encoding="utf-8"?>

123456

“”")))
}

val auth = scenario(“getauth”).exec(pl.layer7)
val pl1_1 = scenario(“claimsummary”).exec(pl.pl1)

setUp(auth.inject(rampUsers(1) during (1 seconds)).protocols(httpProtocol_1),
pl1_1.inject(nothingFor(10 seconds),
rampUsers(10) during (5 seconds)).protocols(httpProtocol))
}
`

Error:

value asJSON is not a member of io.gatling.http.request.builder.HttpRequestBuilder possible cause: maybe a semicolon is missing beforevalue asJSON’?

“”")).asJSON.check(status.is(200)).check(jsonPath("$.access_token").saveAs(“authToken”)))

Thank you Stephane! Could you please take a look at the following issue too, that’s second part of the problem statement where I need to pass auth token to a set of requests which need to run in parallel but auth token need to be executed only once. Appreciate all your help!

I noticed that in the new versions of Gatling, there are some errors on over or asJSON. Then, I got that they’ve renamed.

You’re really coming from a very old version, this renaming happened in Gatling 3.0, more than 2 years ago.
See https://gatling.io/docs/current/migration_guides/2.3-to-3.0/

Yes, now I got that. I was following an old course about Gatling and faced some problems like:

  • value over is not a member of io.gatling.core.controller.inject.open.RampBuilder
  • value asJSON is not a member of io.gatling.http.request.builder.HttpRequestBuilder
