Scala: InputStream to Array[Byte]

Question

With Scala, what is the best way to read from an InputStream to a bytearray?

I can see that you can convert an InputStream to char array

Source.fromInput         


        

Answer 1

How about:

Stream.continually(is.read).takeWhile(_ != -1).map(_.toByte).toArray

Update: Use LazyList instead of Stream (since 2.13.x deprecated)

LazyList.continually(is.read).takeWhile(_ != -1).map(_.toByte).toArray
