Java: da un InputStream ad un array di byte
Questa semplice funzione prende in ingresso un InputStream e restituisce un array di byte.
public static byte[] readBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); try { byte[] b = new byte[1024]; int len = 0; while ((len = inputStream.read(b, 0, b.length)) != -1) { outputStream.write(b, 0, len); } } finally { if (inputStream != null) { try { inputStream.close(); } catch (Throwable t) { } } try { outputStream.close(); } catch (Throwable t) { } } return outputStream.toByteArray(); } |
