        if (msg instanceof HttpResponse)
        {
            HttpResponse response = (HttpResponse) msg;
            System.out.println("CONTENT_TYPE:" + response.headers().get(HttpHeaders.Names.CONTENT_TYPE));
        }
        if(msg instanceof HttpContent)
        {
            HttpContent content = (HttpContent)msg;
            ByteBuf buf = content.content();
            System.out.println(buf.toString(io.netty.util.CharsetUtil.UTF_8));
            buf.release();
        }
    }
