Grails, getting InputStream from Controller (or even Servlet)

I'm trying to get inputStream from request, but it's always empty. Any idea how to get the contents of it? I'm trying to make a DataInputStream from it.

For me it works when I request the controller method with "application/octet-stream" MIME and send some data within the request. Than in the controller I can simply do:

import org.apache.commons.io.IOUtils

def test() {
   byte[] requestData = IOUtils.toByteArray(request.getInputStream())
}

That's it :-)

Are you uploading multipart requests? The request may have already been processed into a Spring MultipartRequest by Grails in which case you can use getFile() to get the upload contents.

If not, then request.inputStream should work fine.
