In the following code, I am getting a token in the first Gatling request, saving it in a variable named auth. However, when I try to use it in the second request, it is sending empty string in place of auth variable. So for some reason, the auth string is not being updated till the time it is being used in the second request. Can anyone suggest any workaround so that I can use the value returned in one request into another request?
Code:
val headers_10 = Map("Content-Type" -> "application/x-www-form-urlencoded")
var a= "[email protected]"
var auth = ""
val scn = scenario("Scenario Name") // A scenario is a chain of requests and pauses
.exec(http("request_1") // Here's an example of a POST request
.post("/token")
.headers(headers_10)
.formParam("email", a)
.formParam("password", "password")
.transformResponse { case response if response.isReceived =>
new ResponseWrapper(response) {
val a = response.body.string
auth = "Basic " + Base64.getEncoder.encodeToString((a.substring(10,a.length - 2) + ":" + "junk").getBytes(StandardCharsets.UTF_8))
}
})
.pause(2)
.exec(http("request_2")
.get("/user")
.header("Authorization",auth)
.transformResponse { case response if response.isReceived =>
new ResponseWrapper(response) {
val a = response.body.string
}
})
You should store the value you need in the session. Something like this will work, although you'll have to tweak the regex and maybe some other details:
val headers_10 = Map("Content-Type" -> "application/x-www-form-urlencoded")
var a= "[email protected]"
var auth = ""
val scn = scenario("Scenario Name") // A scenario is a chain of requests and pauses
.exec(http("request_1") // Here's an example of a POST request
.post("/token")
.headers(headers_10)
.formParam("email", a)
.formParam("password", "password")
.check(regex("token: (\\d+)").find.saveAs("auth")))
.pause(2)
.exec(http("request_2")
.get("/user")
.header("Authorization", "${auth}"))
Here's the documentation on "checks", which you can use to capture values from a response:
http://gatling.io/docs/2.2.2/http/http_check.html
Here is the documentation on the gatling EL, which is the easiest way to use session variables (this is the "${auth}" syntax in the last line above):
