Compilation failure - HTTP DELETE on body

Gatling (Open-Source)

Either write a feeder that generates random data: https://github.com/excilys/gatling/wiki/Inject-User-Specific-Data

or instead of passing a String, pass a function: https://github.com/excilys/gatling/wiki/Session#functions

Thanks, Will this work with gatling 1 also?

23

Absolutely.

Hi All,

I am calling a java api to get the post pody in my scenario exec method. But when I run it it just picks the value of the body only once. But I would like it to call the exec everytime so that it fetches me a new body.

Code below.

package custom.protocol.test

import com.excilys.ebi.gatling.core.scenario.configuration.Simulation
import com.excilys.ebi.gatling.core.Predef._
import com.excilys.ebi.gatling.http.Predef._
import bootstrap._
import assertions._
import scala.concurrent.duration._
import com.inmobi.crypto.getMessageBody
import com.inmobi.crypto.CarbEncodingWrapper

class GetPromotedAppsSimulation_lh1_postencryption_new extends Simulation {

val httpConf = httpConfig
.baseURL(“http://usignal01.app.vip.lhr1.inmobi.com/carb/v1/app_relevance_get”)
.acceptHeader(“text/javascript, text/html, application/xml, text/xml, /”)
.acceptEncodingHeader(“gzip,deflate,sdch”)

b = new CarbEncodingWrapper
val headers_1 = Map(“Keep-Alive” → “200000”)
val scn = scenario(“Gatling GetPromotedApps”)
.during(43200) {
exec(http(“request_1”)
.post("") .body(b.getEncodedbody(getMessageBody.getRandomBody()))
.check(status.is(200)))
.pause(0)
}

setUp(scn.users(10).ramp(5).protocolConfig(httpConf))
;assertThat(global.responseTime.max.lessThan(100))

}

You hâve

26

You have to pass a session function or your method will be called only once on start up

I am facing issues in running my simulation where I just want to pass body for a post request to an URL. Please help me resolving this.

My simulation:

val headers_10 = Map(“Content-Type” → “”“application/x-www-form-urlencoded”"")

val scn = scenario(“Gatling GetConfig”)

.exec(http(“request_1”)
.post("")
.headers(headers_10)
.body(“sm=QAAAAAAAAABWiH61n2_zbRRChYLHhKLSdDjoIegGNuP8VdQo-Xp-KJfBPeaYMefz7IikVkKc-Ls8%0Aj448dImG7axFov1trLcAUAAAAAAAAACwWzbUw7Ws7s0AM-CTI2O4yzOlCg36tG8WqCB8_S_YIxhh%0Azc83oikwpM-7NQCuXUYZFeTTp9vnZyJSVGllmgiYB4Ts3YIfdQilIERAQB0LORQAAAAAAAAAc5Cn%0Ac6quLeHrpaQGwyoM0R_5g5A%3D%0A&sn=1”)
.check(status.is(200)))

.pause(0)

// setUp(scn.users(10).protocolConfig(httpConf))
//;assertThat(global.responseTime.max.lessThan(100))

setUp(
scn.inject(
nothingFor(0 seconds), // 1

constantUsersPerSec(1000) during (100 seconds) // 4
)).assertions(global.responseTime.max.lessThan(50), global.successfulRequests.percent.greaterThan(95))
}

I get an error:

Gatling 1 is no longer supported. Please upgrade.

29

I am using gatling 2, But I am not sure how to fix the error in the above sent snippet.

30

I want to pass the string as a body in a http post call and I am using the below scn: Using gatling 2

val scn = scenario(“Gatling GetConfig”)

.exec(http(“request_1”)
.post("")
.headers(headers_10)
.body(StringBody("""{ “myContent”: “sm=QAAAAAAAAABWiH61n2_zbRRChYLHhKLSdDjoIegGNuP8VdQo-Xp- KJfBPeaYMefz7IikVkKc-Ls8%0Aj448dImG7axFov1trLcAUAAAAAAAAACwWzbUw7Ws7s0AM-CTI2O4yzOlCg36tG8WqCB8_S_YIxhh%0Azc83oikwpM-7NQCuXUYZFeTTp9vnZyJSVGllmgiYB4Ts3YIfdQilIERAQB0LORQAAAAAAAAAc5Cn%0Ac6quLeHrpaQGwyoM0R_5g5A%3D%0A&sn=1” }"""))

.check(status.is(200)))

.pause(0)

But I am not able to produce the correct body, I want the following string in the body:
sm=QAAAAAAAAABWiH61n2_zbRRChYLHhKLSdDjoIegGNuP8VdQo-Xp- KJfBPeaYMefz7IikVkKc-Ls8%0Aj448dImG7axFov1trLcAUAAAAAAAAACwWzbUw7Ws7s0AM-CTI2O4yzOlCg36tG8WqCB8_S_YIxhh%0Azc83oikwpM-7NQCuXUYZFeTTp9vnZyJSVGllmgiYB4Ts3YIfdQilIERAQB0LORQAAAAAAAAAc5Cn%0Ac6quLeHrpaQGwyoM0R_5g5A%3D%0A&sn=1
