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

def inputStreamToByteArray(is: InputStream): Array[Byte] = {
    val buf = ListBuffer[Byte]()
    var b = is.read()
    while (b != -1) {
        buf.append(b.byteValue)
        b = is.read()
    }
    buf.toArray
}
