[akka-user] Make HTTPS request using akka-http to jenkins server

[Ajinkya Shukla]

How can i make the following HTTPS request using akka-http to a jenkins 
server?

curl -v -k --user "$USERNAME:$API_TOKEN" https://HOSTNAME.com/api/json

The curl produces the following HTTPS request:

Connected to HOST.com
* TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
* Server certificate: Default Company Ltd
* Server auth using Basic with user 'USERNAME'
> GET /api/json HTTP/1.1
> Host: HOSTNAME
> Authorization: Basic API_TOKEN
> User-Agent: curl/7.43.0
> Accept: */*

However I am not able to make the above request using akka-http. I get a 
SSL certificate error. Here is my code:


import javax.net.ssl.SSLContext

import akka.actor.{Actor, ActorLogging, ActorSystem}
import akka.http.scaladsl.model._
import akka.http.scaladsl.model.headers.{Authorization, 
BasicHttpCredentials}
import akka.http.scaladsl.{Http, HttpsConnectionContext}
import akka.stream.{ActorMaterializer, ActorMaterializerSettings, 
Materializer}
import akka.util.ByteString
import com.typesafe.sslconfig.akka.AkkaSSLConfig
import com.typesafe.sslconfig.ssl.{SSLConfigSettings, SSLParametersConfig}

import scala.concurrent.Future

class Main extends Actor
  with ActorLogging {

  import akka.pattern.pipe
  import context.dispatcher

  implicit val system = ActorSystem("HelloSystem")

  final implicit val materializer: ActorMaterializer = 
ActorMaterializer(ActorMaterializerSettings(context.system))

  val modernHttpsConnectionContext: HttpsConnectionContext = new 
HttpsConnectionContext(
    SSLContext.getDefault,
    enabledProtocols = Some("TLSv1.2" :: "TLSv1.1" :: Nil)
  )

  class HttpClientSingleCustomHttps(connectionContext: 
HttpsConnectionContext)
                                   (implicit val system: ActorSystem, val 
mat: Materializer) {
    def sendHttpReq(req: HttpRequest): Future[HttpResponse] =
      Http().singleRequest(req, connectionContext = 
connectionContext).pipeTo(self)
  }

  override def preStart() = {
    log.info("Making request")
    val client = new 
HttpClientSingleCustomHttps(modernHttpsConnectionContext)
    val jenkinsRequest: HttpRequest = HttpRequest(
      uri = "https://HOSTNAME.com/api/json";,
      headers = List(
        Authorization(BasicHttpCredentials("USERNAME","PASSWORD"))
      )
    )
    client.sendHttpReq(jenkinsRequest)
  }

  def receive = {
    case HttpResponse(StatusCodes.OK, headers, entity, _) =>
      log.info("Got response, body: " + 
entity.dataBytes.runFold(ByteString(""))(_ ++ _))
    case HttpResponse(code, _, _, _) =>
      log.info("Request failed, response code: " + code)
  }

}
