[GATLING-2.0.0M3A] Reading and setting Cookies

Hello

I have a web site that set a cookie with a path “/access”. But I would like this cookie to be used on path “/”.

I tried this code, to read the cookie’s value but it doesn’t work. I have an exception.

.exec(http(“request_Login”)
.post("/access")
.queryParam(“action”, “login”)
.body(StringBody("""{“login”:“adm”,“password”:“adm”}"""))
.headers(headers_json)
)
.pause(1)
.exec( session => {
import io.gatling.http.cookie._
import java.net.URI

val ck = session(“gatling.http.cookies”).as[CookieJar].get(URI.create("//bdist")).find(
_.getName == “session-id”
)
session.set(“test”, ck.getOrElse(null).getValue)
})

Well

Unless there is a mean to change the thread title we may better continue on this one … (sorry for this)

So in the mean time, I found that my domain was wrong: using

val ck = session(“gatling.http.cookies”).as[CookieJar].get(URI.create(“http://bdist/access”)).find(
_.getName == “session-id”
)
session.set(“test”, ck.getOrElse(null).getValue)
worked !

Now I found out about the https://github.com/excilys/gatling/wiki/Gatling-2#wiki-http-misc
But honestly I have no idea how to use this:
exec(addCookies(url: Expression[String], cookie: Cookie, cookies: Cookie*))

To sum up the discussion about Cookie in 2.0.0
First do not use 2.0.0M3a.
Use M4 if available: https://github.com/excilys/gatling/wiki/Downloads
Or this Snapshot: https://oss.sonatype.org/content/repositories/snapshots/io/gatling/highcharts/gatling-charts-highcharts/2.0.0-SNAPSHOT/

You may have to:

  • Add the libraries: logback- classic and core from previous Gatling lib.
  • Remove the examples (compilation errors)

The DSL has changed a bit (simply start with the recorder to get a valid example):

Then the code example:

.exec(http(“request_Login”)
.post("/access")
.queryParam(“action”, “login”)
.body(StringBody("""{“login”:“adm”,“password”:“adm”}"""))
.headers(headers_json)
)
.pause(1)
.exec( session => {
import io.gatling.http.cookie._
import java.net.URI

val ck = session(“gatling.http.cookies”).as[CookieJar].get(URI.create(“http://bdist/access”)).find(
_.getName == “session-id”
)
session.set(“test”, ck.getOrElse(null).getValue)
})
.exec(
addCookie(“session-id”, “${test}”) // Default to path=/
)

The missing Logback dependencies in the bundle was a bug, now fixed :slight_smile:
Grab the latest bundle from Sonatype snapshots repository and you’ll get a fully working bundle !
