Converting an image from HTTP response into byte array in Grails?

Question

I have a Grails action inside a controller. In this action I use:

def url = "http://www.somedomain.com/image/test.jpg"
def requestFactory = new SimpleClientHttpRequestFactory()
def request = requestFactory.createRequest(uri, method)
...
def response = request.execute()
  if(statusCode == HttpStatus.OK) {
def responseImage = response.body.text
}

This returns a jpg image in my response.body.text object. I have no idea how I can handle this image. How can I convert this image to a byte array?

Please clarify, the question is unclear. Sending a http request to an image seems a bit odd.. — Marco

@Marco I updated the question. Do you have any idea what to do? — Michael

ClientHttpResponse.getBody() returns an InputStream, so you could just do response.body.bytes (using the Groovy-JDK InputStream.getBytes() extension) instead of response.body.text
