Class StrictForm

  • public abstract class StrictForm
extends java.lang.Object
    Read-only abstraction on top of application/x-www-form-urlencoded and multipart form data, allowing joint unmarshalling access to either kind, **if** you supply both, a akka.http.scaladsl.unmarshalling.FromStringUnmarshaller as well as a akka.http.scaladsl.unmarshalling.FromEntityUnmarshaller for the target type T. Note: In order to allow for random access to the field values streamed multipart form data are strictified! Don't use this abstraction on potentially unbounded forms (e.g. large file uploads).

    If you only need to consume one type of form (application/x-www-form-urlencoded *or* multipart) then simply unmarshal directly to the respective form abstraction (FormData or Multipart.FormData) rather than going through StrictForm.

    Simple usage example: 

    
 val strictFormFuture = Unmarshal(entity).to[StrictForm]
 val fooFieldUnmarshalled: Future[T] =
   strictFormFuture flatMap { form =>
     Unmarshal(form field "foo").to[T]
   }
