How do I check if a file on http exists, using Python/Django?

开发者_运维问答I try to check if file in http://hostname/directory/file.jpg exist

Try urllib2.urlopen:

import urllib2
ret = urllib2.urlopen('http://hostname/directory/file.jpg')
if ret.code == 200:
    print "Exists!"

Note that you don't check if file exists - you check if resource exists

EDIT: The other answer by user Geo is better in that HEAD request can be much more efficient as it doesn't fetch resource content.

You could do it with a HEAD request. Check this question for more info. If you get a status code of 200, it should be ok, but you could check for content type as well.
