Sending binary data with the Restlet client

Question

I'm trying to send a byte[] (using PUT) with Restlet but I can't find any info on how to do it. My code looks like this:

Request request = new Request(Method.PUT, url);
request.setEntity( WHAT DO I PUT HERE?, MediaType.APPLICATION_OCTET_STREAM);

I had expected to find something along the lines of ByteArrayRepresentation, just like there's a JsonRepresentation and a a StringRepresentation but I couldn't find anything.

Answer 1

I believe you want to use an InputRepresentation, like so:

Representation representation = new InputRepresentation(new ByteArrayInputStream(bytes), MediaType.APPLICATION_OCTET_STREAM);
request.setEntity(representation);

Answer 2

I'm not familiar with restlet, but one way to do it would be to base64 encode the data. Then you could handle it like a regular string.

Answer 3

you can try subclassing WritableRepresentation that is especially designed for large representations
