I'm stuck.
path("myPath") {
post {
decodeRequest {
entity(as[String]) {jsonStr => //could not find implicit value
for... FromRequestUnmarshaller[String]
complete {
val json: JsObject = Json.parse(jsonStr).as[JsObject]
val jsObjectFuture: Future[JsObject] = MyDatabase.addListItem(
json)
jsObjectFuture.map(_.as[String])
}
}
}
}
}
How can I unmarshall the request into a string? I found there's a package
import akka.http.scaladsl.unmarshalling.PredefinedFromEntityUnmarshallers
which has a stringUnmarshaller and PredefinedFromStringUnmarshallers but I
can't find how to use this in my code. The stringUnmarshaller implicits
return FromEntityUnmarshaller not FromRequestUnmarshaller, I assume this is
the problem but how to I get a FromRequestUnmarshaller?
Thanks in advance,
Ivan
