How to get value from Cookie returned by server

[Jordi Medina Andreu]

Hi there,

I'm trying to get value from a cookie returned by the server in header to a GET request. I would like to use such value to next request (POST).

So far I was focused to print and save the value from the cookie, but I'm not able because uses CookieKey and StoredCookie objects and despite I read some of the email chains from the group, I couldn't find the solution to my problem.

Some support would be really appreciated!  :)

val allSteps = 

exec(getRequestTime)

 

.exec( session => {

    import io.gatling.http.cookie._

    import java.net.URI

      session("gatling.http.cookies").validate[CookieJar].map{

      cookieJar =>

println(cookieJar)

}

    session

  }) 

  

  

  

The result of the println(cookieJar),  is:
  
CookieJar(Map(
CookieKey(bwcfst,cc-test.sagecat.es,/cc/time) -> StoredCookie(BWCFST=wYTtx6HUbUPsUDMiwzBBmgaxKJqWcMn0JDd5lqLWBLA; path=/catc/time; secure; HTTPOnly,true,false,1468232405357), 
CookieKey(bwclocale,sagecat.es,/) -> StoredCookie(bwCurrentLocale=en_US; domain=.sagecat.es; path=/,false,false,1468232405357), 
CookieKey(jsessionid,catc-test.sagecat.es,/cc/time) -> StoredCookie(JSESSIONID=vSxmpOMTLphT8SyOSMs9ScMwGMBlUV3Ku2IvdhKm.cca; path=/catc/time; secure; HTTPOnly,true,false,1468232405357), 
CookieKey(jsessionid,catc-test.sagecat.es,/cc/access) -> StoredCookie(JSESSIONID=V8Xk36hK5ocnDZ9YSwOgggm_xaMYPhhzbJ7SW38o.cca; path=/catc/access; secure; HTTPOnly,true,false,1468232405357), 
CookieKey(csrftoken,sagecat.es,/) -> StoredCookie(csrftoken=1877ad7e80abfb99442d736495a3aa89; domain=.sagecat.es; path=/; secure,false,false,1468232405357)

))

I would like to get value from 'csrftoken' (i.e: 1877ad7e80abfb99442d736495a3aa89), and store in session in order to be used by next request (POST request)

any ideas, please?

thanks a lot!!

Finally I find the way to get the value from the cookie. I'm sharing here:

.exec(session => {

import io.gatling.http.cookie._

        

val ck = session("gatling.http.cookies").as[CookieJar].get(org.asynchttpclient.uri.Uri.create("https://sagecat.es")).find(_.getName == "csrftoken")

//println("X-CSRFToken: " + ck.getOrElse(null).getValue)

session.set("myCookieValue", ck.getOrElse(null).getValue)

})

One question: why do you want to access the cookies in the first place?

Thank you very much for sharing this!

@Stéphane Landelle: the need to get/validate token does exist. In my case, the XSRF token is modified and the following POST requests have to be manually tuned. 

Also my approach is shared as follows, with a regex to extract the token:

val URL = "http://example.com"

val XSRF_COOKIE_NAME = "XSRF-TOKEN"

val cookiePattern = "[A-Za-z-]+=([A-Za-z0-9-]*).*".r  // "xsrf-token=abcd-efgh-ijkl; path=/"

...

exec(session => {

   val token = session("gatling.http.cookies").as[CookieJar]

    .get(Uri.create(URL))

    .find(_.getName == XSRF_COOKIE_NAME) match {

      case None => ""

      case Some(cookie) => match {

        cookie.toString match {

          case cookiePattern(token) => token

          case _ = ""

        }

      }

    }

    session.set("xsrfToken", token)

})

.exec(http("A following request with latest token")

  .post("http://foo.com")

  .header("X-XSRF_TOKEN", "${xsrfToken}")

  .check(status.in(200))

)

Enjoy!

@pythonhicom What you're doing is very wrong. You're hacking a Gatling internal and will be sorry if we change it someday.

So what you're doing is definitively NOT A RECOMMENDED SOLUTION.

There's a built-in for extracting a cookie value from the cookie jar, please use the official way: https://gatling.io/docs/current/http/http_helpers/?highlight=getcookievalue#getting-a-cookie-value

Hi Jordi, glad you made this work. I am wrestling with exactly the same problem for three days already without any luck.

I tried your solution too, but I cannot get your solution to work for me. I get an error message: class CookieJar in package cookie cannot be accessed as a member of package io.gatling.http.cookie

Maybe something has changed since you wrote this. Do you have any idea why I get this message or how to make it work?

Thank you in advance!
