Specifying a request body doing a Gatling POST

Question

I'm a fresh newbie to Gatling. I'm trying to send a POST message to an HTTP API using Gatling. I tried the following:

package app.basic
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._

class basicPost extends Simulation {
  val headers_10 = Map("Content-Type" -> """application/json""")
  object Post {
      // repeat is a loop resolved at RUNTIME
      val post = repeat(50) { 
      exec(http("Post Data")
          .post("/data")
          .queryParam("""size""", "10"))
          .headers(headers_10)
          .body("""{"id1":"0000000000"}""")
          .pause(1)
  }
  }
  val httpConf = http.baseURL("http://amazonperf-env.elasticbeanstalk.com")   
  val users = scenario("Users").exec(Post.post)
  setUp(
    users.inject(rampUsers(1000) over (10 seconds))
  ).protocols(httpConf)
}

However, I get this error when compiling: value body is not a member of io.gatling.core.structure.ChainBuilder possible cause: maybe a semicolon is missing before `value body'?

How do I specify the body of the message that I want to send?

Answer 1

This is old Gatling 1 syntax (Gatling 1 is deprecated and no longer maintained).

Please read the documentation.

In you case, you'd get something like:

.body(StringBody("""{"id1":"0000000000"}"""))
