How to encode the password in Gatling? - base64

Question

I have a requirement in my project to encode the password being sent in the login request. What is the best way to do it?

Answer 1

You can store the credentials in a file as key-value pair. Read the file in vector and then decode the value. The value can be stored in a session and can be used in your Gatling request as below:
import scala.concurrent.duration._
import io.gatling.core.Predef._
import io.gatling.core.structure.ChainBuilder
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._
import io.gatling.jsonpath._
import Headers._
import scala.collection._
import java.time.format.DateTimeFormatter
import java.time.LocalDateTime
import java.time.LocalDate
import io.gatling.core.feeder._
import java.util.Base64
import java.nio.charset.StandardCharsets
import scala.util.matching.Regex
object TestClass {
//Now you can use below code to read the credential file,
val recordsByEnv: Map[String, Seq[Record[Any]]] =
csv("/User/sandy/data/userdetails.csv").readRecords.groupBy { record =>
record("env").toString
}
val passwordByEnv: Map[String, Seq[Any]] = recordsByEnv.mapValues { records =>
records.map { record =>
record("password")
}
}
val password_v = (passwordByEnv.get("env_name").toString)
val password_encoded = password_v.substring(12, (password_v.length - 2))
val credentials = new String(Base64.getDecoder.decode(password_encoded))
//Store the decoded value in session variable
.exec(session => session.set("password", credentials))
.exec(
http("Authorization")
.post("https://XXXX.xxxxxx.com")
.header("Content-Type", "application/x-www-form-urlencoded")
.formParam("password", "${password}")
.formParam("username", "USERNAME")
)
//Below is user details file look like below
//env_name,encoded_password
}
