creating unmarshaller using circe

Question

I am playing with Akka Http client side. I have created a simple request but how can I unmarshal the respose? in the server side it is easy to use circe to marshal the response, but I have difficulties in the client side

import akka.actor.ActorSystem
import akka.http.scaladsl.Http
import akka.http.scaladsl.model.Uri.Query
import akka.http.scaladsl.model._
import akka.http.scaladsl.unmarshalling.Unmarshal
import akka.stream.Materializer

import scala.concurrent.ExecutionContext


class QuestionsFetcher {

  import de.heikoseeberger.akkahttpcirce.CirceSupport._
  import io.circe.generic.auto._

  val baseUrl = "https://somewhere.com"


 def fetch(tag: String)(implicit ac: ActorSystem, materializer: Materializer) = {

implicit val ec: ExecutionContext = ac.dispatcher

val fromDate = DateTime.now.minus(1000 * 60 * 60 * 24)
val uri = Uri(baseUrl).withQuery(Query("order"->"desc"))
val request = HttpRequest(HttpMethods.GET, uri)

Http().singleRequest(request)
    .map(r => Unmarshal(r.entity.withContentType(ContentTypes.`application/json`)).to[Items])

} }

When running the code I am getting ErrorFuture(io.circe.ParsingFailure: expected json value got (line 1, column 1))

Can you say a little more about your imports? Can you resolve an Encoder[Items] in the same scope? — Travis Brown
