Best practice to receive binary data

[Ori S]

Hi all.

I'm working on a REST API and arrived now to the point where I need to receive binary uploads (request), like images. The response will be JSON.

Is there a best practice of how this should be done in RestExpress?

Do I need a serializer to parse incoming data or Netty/RestExpress does that for me?

An example would be very welcome, thanks in advance.

I'll be replying to my own question in favor of anyone wondering the same. It was straightforward.

// The request's input stream.
InputStream is = null;


// The output stream to save uploaded data.
OutputStream os = null;


try {
  // Get the upload as a binary file.
  is = request.getBodyAsStream();
  if(null == is) {
    throw new BadRequestException("Request data is invalid");
  }


  // Save to output stream.
  os = new BufferedOutputStream(new FileOutputStream(file));


  byte[] buffer = new byte[8192];
  int readBytes;
  while(-1 != (readBytes = is.read(buffer))) {
    if(0 < readBytes) {
      os.write(buffer, 0, readBytes);
    }
  }
} finally {
  if(null != is) {
    try { is.close(); } catch(Exception ignored) { }
    is = null;
  }
  if(null != os) {
    try { os.close(); } catch(Exception ignored) { }
    os = null;
  }
}
