Parsing a Json response returned to Gatling

Question

I am trying to parse a json response returned to gatling by the server.

My response from server is:

SessionAttribute(
  Session(
    GetServices,
    349

It might be easiest to use a little bit more jsonPath to pull out the id you need, storing that in its own variable for later use. Remember that jsonPath is still a CheckBuilder, so you can't just access the result directly - it might have failed to match.

Converting it to an Option[String] seems like a reasonable thing to do though.

So your final few lines would become:

    ...
    .check(
      jsonPath("$.id").saveAs("myresponseId")
    )
  )
).exec(session => {
  val maybeId = session.get("myresponseId").asOption[String]
  println(maybeId.getOrElse("COULD NOT FIND ID"))
  session
})
