Hi there,
here is my simple scenario with a StringBody

val scn = scenario(“get topic scenario”)

.feed(ssv(“gabriel/devices.ssv”).circular)

.exec(

http(“getTopic”)

.post(ServiceEndpoints.profile+"/device/subscriptions")

.headers(HeaderMapHelper.createHeaderMap(“POST”, null , “${deviceId}”, “${deviceInfo}”, “${userAgent}”))

.body(StringBody("""{ “id”: “001B1D25-D31C-453B-85D2-D00DB5A19F25”, “type”: 2, “label”: “KATWARN Dev”, “topic_id”: “katwarn-dev-topic”, “provider_id” : “kwrn_de”, “enabled”: true }""")).asJSON

.signatureCalculator(ProfileHmacSignatureCalculator)

.check(status.saveAs(“status”), status.is(200)))

When i try to access the requests body by request.getStringData() i get null.

What’s wrong

Thanks in advance

signaturecalCulator now uses request.getCompositeByteData() ro access the body.

Problem solved

Hi,

Actually, it depends on what kind of body you pass, but indeed, when passing an EL string, there’s a good chance you now get a composite. Beware to duplicate if you read it in the signature calculator so the positions are right when finally sending the body.
