Gatling switch protocols during scenario - gatling

Question

I'm trying to create a Gatling scenario which requires switching the protocol to a different host during the test. The user journey is
https://example.com/page1
https://example.com/page2
https://accounts.example.com/signin
https://example.com/page3
so as part of a single scenario, I need to ether switch the protocol defined in the scenario set up, or switch the baseUrl defined on the protocol but I can't figure out how to do that.
A basic scenario might look like
package protocolexample
import io.gatling.core.Predef._
import io.gatling.http.Predef._
class Example extends Simulation {
val exampleHttp = http.baseURL("https://example.com/")
val exampleAccountsHttp = http.baseURL("https://accounts.example.com/")
val scn = scenario("Signin")
.exec(
http("Page 1").get("/page1")
)
.exec(
http("Page 2").get("/page2")
)
.exec(
// This needs to be done against accounts.example.com
http("Signin").get("/signin")
)
.exec(
// Back to example.com
http("Page 3").get("/page3")
)
setUp(
scn.inject(
atOnceUsers(3)
).protocols(exampleHttp)
)
}
I just need to figure out how to ether switch the host or protocol for the 3rd step. I know I can create multiple scenarios but this needs to be a single user flow across multiple hosts.
I've tried directly using the other protocol
exec(
// This needs to be done against accounts.example.com
exampleAccountsHttp("Signin").get("/signin")
)
which results in
protocolexample/example.scala:19: type mismatch;
found : String("Signin")
required: io.gatling.core.session.Session
exampleAccountsHttp("Signin").get("/signin")
and also changing the base URL on the request
exec(
// This needs to be done against accounts.example.com
http("Signin").baseUrl("https://accounts.example.com/").get("/signin")
)
which results in
protocolexample/example.scala:19: value baseUrl is not a member of io.gatling.http.request.builder.Http

Answer 1

You can use an absolute URI (inclusive protocol) as a parameter for Http.get, Http.post and so on.
class Example extends Simulation {
val exampleHttp = http.baseURL("https://example.com/")
val scn = scenario("Signin")
.exec(http("Page 1").get("/page1"))
.exec(http("Page 2").get("/page2"))
.exec(http("Signin").get("https://accounts.example.com/signin"))
.exec(http("Page 3").get("/page3"))
setUp(scn.inject(atOnceUsers(3))
.protocols(exampleHttp))
}
see: https://gatling.io/docs/current/cheat-sheet/#http-protocol-urls-baseUrl
baseURL: Sets the base URL of all relative URLs of the scenario on which the configuration is applied.

Answer 2

I am currently working in gatling.
SOLUTION:
=> WHAT WE USE IF WE HAVE ONE HTTPBASE:
var httpConf1= http.baseUrl("https://s1.com")
=>FOR MULTIPLE HTTPBASE:
var httpConf1=http.**baseUrls**("https://s1.com","https://s2.com","https://s3.com")
You can use baseUrls function which takes a list of httpBase urls.
ANOTHER METHOD:
Reading from csv file all httpbase and storing it in list buffer in scala language and then converting it into list while passing it in http.baseUrls
var listOfTenants:ListBuffer[String] = new ListBuffer[String] //buffer
var httpConf1=http.**baseUrls**(listOfTenants.toList) //converting buffer to list.
Hope it helps!.
Thank you.😊
