Gatling session - get attribute as Long-CodePudding

I am a new in Scala and got some problems with casting from String to Long. I try to get Gatling session value as Long in request. Before in exec() part, I try to set the userId value

def setUserId(): ChainBuilder = {
    exec(session => session
      .set("userId", Random.nextLong())
    )
  }

Next, in request creator I want to use it like that because I need a new userId every call:

object UserRequestCreator {

  def sampleUserRequest(currency: String): Request = {

    Data data = new Data()

    data.setUserId("${userId}".toLong)
    data.setCurrency(currency)
  }
}

Test scenario:

exec(setUserId())
      .exec(http("postUser")
        .post(endpointUser).asXml
        .headers(headers)
        .body(StringBody(toXmlString(sampleUserRequest("EUR"), classOf[Request])))
        .check(status.is(200))

but receive error:

java.lang.NumberFormatException: For input string: "${userId}"

How to fix that in Scala? I also try Long.valueOf, JLong.parseLong("${userId"}, 16), Try(BigDecimal(...)) and more but nothing can help. I think the problem is with $ symbol, but I don't see any different way to get this value from the session. Maybe it is possible to store Long in the Gating session?

CodePudding user response：

From the documentation and based on your current code, one way to do it is like that:

// with a function payload
http("name").post("/")
  .body(StringBody(session => s"""{ "foo": "${session("dynamicValueKey").as[String]}" }"""))

Thus, in your case:

StringBody(session => toXmlString(sampleUserRequest(session)("EUR"), classOf[Request])

def sampleUserRequest(session: Session)(currency: String): Request = {
  //...
  data.setUserId(session("userId").as[Long])
}
