Is it possible to pass the below json array as whole?

When using Stringbody, it requires to hardcode key and when using ElFileBody or RawFileBody, able to pass only on json.

I want to pass the below json array in body. Can someone pls help?

[
{“twitter”: “12”,
“fields”: {
“recent_note”: “asdasdasdasdaasdada”
}
},
{“twitter”: “11”,
“external_id”: 1212,
“last_login”: “2020-12-12”
},
{“twitter”: “11”,
“external_id”: 1212,
“first_login”: “2020-12-12”,
“fields”: {
“city”: “chennai”,
“state”: “tn”,
“phone_numbers”: ["+1221312","+1827981279"]
}
}
]

Try to give a List[Map[String, Any]]

Example:

exec(session => 
  session.set("data", List(
    Map(
      "twitter" -> "12",
      "fields" -> Map("recent_note" -> "asdasdasdasdaasdada")
    ),
    Map(
      "twitter" -> "11",
      "external_id" -> 1212,
      "last_login" -> "2020-12-12"
    ),
    Map(
      "twitter" -> "11",
      "external_id" -> 1212,
      "first_login" -> "2020-12-12",
      "fields" -> Map(
        "city" -> "chennai",
        "state" -> "tn",
        "phone_numbers" -> List("+1221312","+1827981279")
      )
    )
  ))).exec(http("My request").post("my URL").body(StringBody("""${data.jsonStringify()}""").asJson)

Sorry! Reframing the question again. I wanna pass the json object from the json array one at a time. Say

{“twitter”: “12”,
“fields”: {
“recent_note”: “asdasdasdasdaasdada”
}} for one user/ one req

{“twitter”: “11”,
“external_id”: 1212,
“last_login”: “2020-12-12”
} for next req/other consecutive user

setUp(
theScenarioBuilder.inject(atOnceUsers(3)) // in case 3 json objects
).protocols(theHttpProtocolBuilder)

Update: Able to pass the data for single user

val theScenarioBuilder: ScenarioBuilder = scenario(“Scenario1”)
.exec(session => session.set(“data”, List(
Map(
“twitter” → “12”,
“fields” → Map(“recent_note” → “asdasdasdasdaasdada”)
),
Map(
“twitter” → “11”,
“external_id” → 1212,
“last_login” → “2020-12-12”
))))
.foreach("${data}", “contact”) {
exec(
/* myRequest1 is a name that describes the request. */
http(“myRequest1”)
.post("/")
.header(“Content-Type”, “application/json”)
.body(StringBody("""${contact.jsonStringify()}"""))
.asJson)
}

setUp(
theScenarioBuilder.inject(atOnceUsers(1))
).protocols(theHttpProtocolBuilder)

Can you help me achieve this for multi users? I cannot repeat the same data for second user as I have unique fields.

I have figured something more like a hack. If there’s any better solution pls lmk.

val jsonNodes: Array[JsonNode] = new ObjectMapper().readValue(getClass.getResourceAsStream("/contactdata.json"), classOf[Array[JsonNode]])
var count = jsonNodes.length

def getMap(session: Session, jsonNode: Array[JsonNode], countVariable: SessionAttribute): String = {
val contactTocreate = session(“countVariable”).as[Int]
jsonNode.apply(contactTocreate).toString
}

val theScenarioBuilder: ScenarioBuilder = scenario(“Scenario1”)
.repeat(2, “n”) {
exec(session => {
count = count -1
session.set(“countVariable”, count)
})
.exec(session => {
session.set(“counter”, getMap(session, jsonNodes, session(“countVariable”)))
})
.exec(
/* myRequest1 is a name that describes the request. */
http(“myRequest1”)
.post("/")
.header(“Content-Type”, “application/json”)
.body(StringBody("""${counter}""")).asJson)
}

setUp(
theScenarioBuilder.inject(atOnceUsers(2))
).protocols(theHttpProtocolBuilder)

2 users 2 requests each, data obtained from the same file ( contains json array of json obj ) which is processed and stored in jsonNode

What I understand is that you want to feed your user with different data per user => use a feeder

Yeah but it is multiple user multiple requests. feeders work well for multi user single req in my case because I have unique fields in the json and if the same json is used for 2nd time 400 will be thrown
