I have the response in a HTTP Response object named 'response'.

Now, how do I extract the following from the HTTPResponse object??--

(1) Response content as byte[] (2) Content length (3) Mime type (4) Charset

Answer 1

HttpEntity entity = response.getEntity();
InputStream instream = entity.getContent();
instream.read();

That's the main codes. You can see the examples in:httpcomponents-client-4.1.3\examples\org\apache\http\examples\client
