Download and save a picture - urllib
Hi all, in order to download an image. In order to correctly retrieve the image I need to set the referer and handle cookies. opener = urllib.request.build_opener(urllib.request.HTTPRedirectHandler (), urllib.request.HTTPCookieProcessor()) urllib.request.install_opener(opener) req = urllib.request.Request(http://myurl/image.jpg;) req.add_header(Referer, http://myulr/referer.jsp;) r = urllib.request.urlopen(req) with open(image.jpg, w ) as fd: print(r.read(), file=fd) I'm not able to correctly save the image. In fact it seems that it it saved in hex format. Any suggestion? -- http://mail.python.org/mailman/listinfo/python-list

It sure isn't - either the request fails because the website doesn't allow it due to missing cookies or similar stuff - or you get the binary data. But you should be aware that in the interpreter, strings are printed out with repr() - which will convert non-printable characters to their hex-representation to prevent encoding/binary-data-on-teriminal-issues.

You were right, the problem was with the print function, using a normal write everythong works fine. Il Thu, 10 Sep 2009 18:56:07 +0200, Diez B.
