Alli,
Yes, I think your want to go with a DispatchPF to handle the destination of
the POST request from your Flash component.
DispatchPF {
case r @ Req("upload" :: "thing" :: Nil, "", PostRequent) if
r.uploadedFiles.exists(_.name == "upload") =>
() => {
val uploadedFile = r.uploadedFiles.find(_.name == "upload").get
val fileBytes = uploadedFile.file
... do stuff here
val newFileBytes: Array[Byte]
val headers: List[(String, String)]
Full(InMemoryResponse(newFileBytes, headers, Nil /* no cookies sent back
*/, 200))
}
}
Thanks,
David
