Gatling: How should I transform a binary response to json and then check it? -
i have page returns pretty big response body binary, when decoded plain text response in json format.
i want transform response can traversed json , checked.
for example:
import org.asynchttpclient.util.base64 import io.gatling.http.response._ import java.nio.charset.standardcharsets.utf_8 // .... val read = exec(http("get results") .get("/foo?bar=baz") // response in binary .transformresponse { case response if response.isreceived => new responsewrapper(response) { override val body = new bytearrayresponsebody(base64.decode(response.body.string), utf_8) } } .check( jsonpath("$.alpha.beta").exists.saveas("gamma") ) ) but throws error:
