Hello everyone, for akka-http when handling a POST request, if I have my
entity as a Multipart.FormData ,
and I POST some JSON and a binary file, how can I split the two when I
parse the formData ?
This is what I come up with so far
path("upload") { /* uploads a file to the database */
post {
entity(as[Multipart.FormData]) { (formData) =>
val uploadedUrlsFuture = formData.parts.map(_.entity.dataBytes
).mapAsync(parallelism = 1)(part =>
part
.map(_.toArray)
.runFold(ByteString())((totalBytes, bytes) => totalBytes
++ bytes)
.map(_.toArray[Byte]).map(ResourceManager.saveFile(_)) /*
TODO update this to a service */
).grouped(100).runWith(Sink.head)
complete(OK)
}
}
}
So if I have an Content-Length of 2 in a scenario where I post an JSON
Object and a binary file,
is there a way to split that up and handle the two separately?
And is this a good way to provide an upload functionality to a backend
trough akka-http and akka-streams (are there better ways to achieve this)?
