Type mismatch error when trying to pass a string as parameter to .body for a POST request

[uguduru]

Hi Everyone,

    I am new to Gatling and I am trying to fire a basic POST request with a single parameter. It is throwing me an type mismatch error when I passed a string as parameter to the '.body' method. I also tried using '.param' but got a  '406 Not acceptable'  as response from the server. Any help is greatly appreciated. I was able to successfully test the same scenario with JMeter.

URL to test: https://uat.servicegateway.com/api/FindServiceProviderBySPID?authtoken=MFxnKqyKgcQqBPrT93OJOGqgJs/qOadikDvBY5bEk8GGoMMPhqrp

POST body or param : {"ServiceProviderIdentifier":2108231}

My Simulation:

import io.gatling.core.Predef._

import io.gatling.core.session.Expression

import io.gatling.http.Predef._

import io.gatling.jdbc.Predef._

import io.gatling.http.Headers.Names._

import io.gatling.http.Headers.Values._

import io.gatling.http.request._

import scala.concurrent.duration._

import bootstrap._

import assertions._

class ServiceGatewayRequest extends Simulation {

val httpProtocol = http

.baseURL("https://uat.servicegateway.com:443")

.connection("keep-alive")

val header = Map(

"""Access-Control-Allow-Origin""" -> """*""",

"""Access-Control-Allow-Headers""" -> """Origin, X-Requested-With, Content-Type, Accept""",

"""Content-Type""" -> """application/json""")

.headers(header))

val scn = scenario("Servive Gateway Request")

.exec(http("Fetch SP Details and Categories")

.post("""https://uat.servicegateway.com/api/FindServiceProviderBySPID?authtoken=MFxnKqyKgcQqBPrT93OJOGqgJs/qOadikDvBY5bEk8GGoMMPhqrp""")

.headers(header)

.body("""{ "ServiceProviderIdentifier":"2108231" }""").asJSON)

// .param("ServiceProviderIdentifier","2108231"))

setUp(scn.inject(atOnce(1 user))).protocols(httpProtocol)

The error I am getting when i ran the above simulation is: 

13:38:52.555 [ERROR] i.g.a.ZincCompiler$ - C:\Users\uguduru\Desktop\Work\rapid-fire-master\user-files\simulations\ServiceGatewayRequest.scala:35: type mismatch;

 found   : String("{ \"ServiceProviderIdentifier\":\"2108231\" }")

 required: io.gatling.http.request.Body

You can try the following : 

.body(BodyString("""{ "ServiceProviderIdentifier":"2108231" }""")).asJSON

A bit more detailed: I'd say you're using Gatling 2 (which is a work in progress) with the Gatling 1 syntax. As mentioned on every page, the wiki is about Gatling 1, except for the page named Gatling 2: https://github.com/excilys/gatling/wiki/Gatling%202#wiki-bodies
