A suite of scala libraries for building and consuming RESTful web services on top of Akka: lightweight, asynchronous, non-blocking, actor-based, testable
and i do have
import com.konga.order.models.OrderJsonSupport._
import DefaultJsonProtocol._
but now .. nothing matched .. that was very confusing
How spray process actorRef as a response?
please ask on gitter.im/akka/akka btw :)
it won’t compile, exactly because the question you ask can’t be answered statically — akka http enforces these things
Curious if this is a known thing before I open up a ticket.
RouteTest in the testkit appears to eagerly create and start the actor system. While this normally wouldn't be an issue, we use ScalaTest's tagging to include/exclude tests. The eager loading slows things down considerably as the actor system will be initialized even though no tests are actually run.
thanks!
although, looks like it's still eager in akka-http, but will upgrade first
@shankarshastri you can use spray-json.
import spray.json._
val jsonString: String = ???
val json: JsObject = jsonString.parseJson.asJsObjector you can declare a class describing this json and declare format for it and then convert to it directly:
class JsonRepr(???)
implicit object ReprFormat extends RootJsonFormat[JsonRepr]{
???
}
import spray.json._
val jsonString: String = ???
jsonString.parseJson.convertTo[ReprFormat]
to specify them in case class
you can then get Map[String, JsValue] of the fields of the JsObject
jsonString.parseJson.asJsObject.fields will return Map[String, JsValue]
I meant code.
@VladislavRybin in akka-http you can use
concat instead of ~ which might be less prone to confusing IntelliJ - not sure if that was in Spray already though (https://doc.akka.io/docs/akka-http/current/routing-dsl/directives/index.html)
please upgrade to akka-http; spray has been end-of-life for years
the upgrade is rather straight forward
@vito-c most people have moved to akka-http and discuss it in akka/akka or https://discuss.akka.io I think
@vito-c for marshalling case classes in akka-http I think both spray-json and play-json are still popular
I'm not sure about websockets specifically but still https://doc.akka.io/docs/akka-http/current/common/json-support.html#json-support might help?
@raboof how would one marshal to a just a Message? I can do it automatically to a MessageEntity
could not find implicit value for parameter m: akka.http.scaladsl.marshalling.Marshal
ler[eneovim.EnMessage,akka.http.scaladsl.model.ws.Message]
[error] val outgoing = Source.fromFuture(Marshal(myMsg).to[Message])
[error] ^
@vito-c do you mean
HttpEntity? It works for those because of the implicit conversion at https://github.com/akka/akka-http/blob/master/akka-http-marshallers-scala/akka-http-spray-json/src/main/scala/akka/http/scaladsl/marshallers/sprayjson/SprayJsonSupport.scala#L65, you might want to introduce a similar one for Message
(you're writing a Scala plugin for neovim? that sounds pretty cool)
@vito-c not really... not sure I understand exactly what you need but something like
implicit def sprayJsonToWsMessageMarshaller[T](implicit writer: RootJsonWriter[T], printer: JsonPrinter = CompactPrinter): Marshaller[T, Message] =
Marshaller.strict(t => Marshalling.Opaque(() => TextMessage(writer.write(t)))) might work?
Hi. The spray testkit doesn't seem to work with contentType. I have an example here: https://github.com/JoeCordingley/spray-marshallersExample where if you hit localhost:8080 with either application/json or application/myJson in the running service it returns the correct contentType but testing the route using spray testkit it always returns application/json
