No Attribute named "authToken" is defined - parameter properly passed though

Gatling (Open-Source)
1

I am capturing auth token as part of first request and trying to use it in the second, but getting the same error “failed to execute: No attribute named ‘authToken’ is defined”. Can someone tell me what am i doing wrong? Because in the execution results, i can see authToken being captured in the session data.

pl1.inject(nothingFor(10 seconds),

Layer7 and p11 are in 2 different chains. So “authToken” captured in layer7 will not be visible in p11 requests. Combine these in 1 scenario and inject the requests.

3

Unfortunately, I can’t combine the two scenarios as I need to execute the second set of scenarios in parallel. Also, layer7 needs to be executed only one in the beginning and not for every single user.

4

If it is only once, one approach is to make a “curl” request to get authToken from shell script and pass it as system property to gatling test.

Then you can read in gatling test like this
val authToken = System.getProperty(“authToken”)

5

It’s hacky, but you can do this by storing the access token from layer7 in a scala variable and then setting it into the session in p11.

so have a var like…

var authToken=""

then in layer7 have a final exec to set the scala var…

`
.exec(session =>{
authToken = session(“authToken”).as[String]
session
}

`

then in p11 have an initial exec to put it in the session…

exec(session=>{ session.set("authToken", authToken) }

note that your call to layer7 will have to complete within the 10 seconds you’ve specified

Thank you, it worked!

Hi Santosh,
Can you please give a code example of curl request and way of setting access token.

Hi Vikram,
Can you please give a code example of the curl request you are making to get the authToken
