Hi all,
I'm trying to use Akka http for large files (300MB is what I'm currently
testing) coming in as multi-part form data. The file gets written straight
to disk. The file ends up being a few MB short of complete and the upload
hangs indefinitely. I had a look at the files and the top and bottom match
so it must have missed a chunk somewhere in between? How would I prevent
this?
The code of interest is below:
val file = new File(localPath)
val sink = SynchronousFileSink(file)
entity(as[Multipart.FormData]) { (formdata: Multipart.FormData) =>
val fileNamesFuture = formdata.parts.mapAsync(1) { p =>
if (p.filename.isDefined) {
println(s"Got part. name: ${p.name} filename: ${p.
filename}")
p.entity.dataBytes.runWith(sink).map { bytesWritten
=>
"""{"result":"Finished upload"}""".parseJson
}
}
Thanks
