Accessing session/feeder values when using perUserKeyManagerFactory

I am trying to use perUserKeyManagerFactory for using multiple key stores. For this i need the system name in each request.

I have created the method createKeyManagerFactory for this. But I can’t reach the values of the session in this method. How can I access the values of the session/feeder in this method?

I am also very new to Scala.

Thanks

My code looks like this :


val feeder = csv("servicesSecureTestData.csv").eager

val stringBody =
 """***"""

def createKeyManagerFactory(systemId: Long): KeyManagerFactory ={
 val keyStore = KeyStore.getInstance("PKCS12")

// here value session is not recognized !!! "Cannot resolve symbol session"
 val attribute: SessionAttribute = session("systemName")
 val systemName = session("systemName").as[String]
 keyStore.load(new FileInputStream("./"+ systemName+".p12"), "123456".toCharArray)
val keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm)
keyManagerFactory.init(keyStore,"123456".toCharArray)
keyManagerFactory}

val httpProtocol = http // 4
 .baseUrl("https://localhost:8443") // 5
 .acceptHeader("text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
 .doNotTrackHeader("1")
 .acceptLanguageHeader("en-US,en;q=0.5")
 .acceptEncodingHeader("gzip, deflate")
 .userAgentHeader("Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0").perUserKeyManagerFactory(createKeyManagerFactory)

val scn = scenario("RegisterSimulation").feed(feeder).exec(http("request_1")
 post("/serviceregistry/register").body(StringBody(stringBody)).asJson)

setUp( // 11
 scn.inject(atOnceUsers(1))
).protocols(httpProtocol)

It’s exactly that: you can’t use the Session when computing per user KeyManager. Find a different strategy.

Thanks for the answer. But what is the sense of giving the virtual user id to the method for perUserKeyManagerFactory? Can I use this virtual user id in my method to access these session attributes somehow?

This id is incremental, you can use it to pick the KeyManager you want, eg use a modulo to do a round-robin.

Ok I get it. It would be nice to have for the future releases, if we can access the session also in this method.
