File upload by urllib2

[Michael Foord]

Does anyone know how to do a 'file upload' using urllib2 ?
There is an example of doing file upload using httplib - on
activestate python cookbook.

I have code that uses a request object to make requests using
urllib2.urlopen (including cookie handling via ClientCookie) - which
means it would be extremely incovenient (including probably not
working without the cookie handling) to have to use httplib. It would
also mean duplicating the code...

I had thought of just adding the headers manually using add_header -
but for multipart data we need boundaries and the suchlike...... Has
anyone done this or know the right incantations to do it ?

Actually, more relevant than my previous post:

Modifying the recipe that's pointed to from that thread very slightly
for urllib2 (untested!):

def post_multipart(url, fields, files):
content_type, body = encode_multipart_formdata(fields, files)
headers = {'Content-type': content_type,
'Content-length': str(len(body))}
req = urllib2.Request(selector, body, headers)
r = urllib2.urlopen(req)
return r.file.read()
If you get trouble, note my comment in that thread about bad servers.

Interesting, I'll give it a try.
