Hi Ujjwala,
An image is binary data, so you should not transform your bytes into
strings. What you probably want is to get your image bytes from "another
api"
as either one ByteString (it will then all be in your server memory at
once, so
this might be bad) or a stream of chunks, a Source[ByteString, Any] which
you
send back as http resonse body.
Maybe this is enough to lead you in the right direction?
def getImageBytesFromOtherApi(): Source[ByteString, Unit] = ??? // call
your other api and get the bytes
val route =
pathEndOrSingleSlash {
get {
complete(HttpResponse(
StatusCodes.OK,
// media type needs to be the type of the image of course!
entity = HttpEntity(MediaTypes.`image/jpeg`,
getImageBytesFromOtherApi())
))
}
}
