Hi Lucian,
As discussed on gitter, I believe this is doable using the formFields
directive for example:
formFields('json, 'file.as[StrictForm.FileData]) { case (json: String,
file: StrictForm.FileData) => // not tested though...
I agree that this should be a) very simple and b) well documented, which it
isn't currently, thus I opened a ticket to improve this, please let us know
of your progress or comments in there:
https://github.com/akka/akka/issues/18471
As for limiting the maximal size of an upload, it’s currently already
possible as you can use this cookbook pattern:
http://doc.akka.io/docs/akka-stream-and-http-experimental/1.0/scala/stream-cookbook.html#Limit_the_number_of_bytes_passing_through_a_stream_of_ByteStrings
We’re contemplating if it can be made available as a simple to use
directive, here’s the ticket (feel free to voice your opinion there or jump
in and help us out :-)):
