findAll() and saveAs() then iterate over List of elements

Gatling (Open-Source)

Hi guys,

I’m new to Scala + Gatling and I’m struggling to iterate over a list of elements. I’m currently using Gatling 2.2.2

Here is what I’m trying to do:

I’m hitting an URL that returns 3 cookie values in this format (it could return more than 3 too):

I’d like to do a forEach() to iterate over each of these 3 values and use the values to make a request for each of them.

I’m able to save this data using findAll() + saveAs() but I’m struggling to break it into 3 different parts. Basically, when I try to iterate over the elements, I keep getting the whole element instead of just each piece. I did some research and it seems I may have to use map() + mkString() + transform() to convert the data structure above in a simpler format that I can iterate, but not really sure how to do it.

Here is how my code looks like (short version of it):

val scn0 = scenario(“FetchCookies”)

.exec(http(“fetch_cookies”).get(“https://myurl.com/getloadtestcookies”).check(regex(".*").findAll.saveAs(“allCookies”)))

.foreach("${allCookies}", “cookie”) {
exec(session => {
println(“Print ALL cookies below:”)
println(session(“allCookies”))

println(“Print INDIVIDUAL cookie below”)
println(session(“cookie”))

session})
}

This is what I get when I print “all cookies” (3 values, as I was expecting):

check(regex(“.*”).findAll.saveAs(“allCookies”))

This regex is too broad. Its not telling the check to capture those three cookies separately.
