I've tried a variety of ways to send "raw multipart data" to twitter's
update_background_image REST api.
specs:
http://apiwiki.twitter.com/REST+API+Documentation#updateprofilebackgroundimage
The problem is that I get back a server error. I'd appreciate any
help. I'm probably misunderstanding "raw multipart data", so feel free
to offer resources that might help.
Currently I'm using python with the urllib and urllib2 standard
libraries. I looked at pycurl but that would be a pain to integrate
because everyone on the project uses different platforms (for which
pycurl doesn't provide binaries) and possess varying levels of
'install-fu'.
I found this to be a useful tutorial on urllib and urllib2:
http://www.voidspace.org.uk/python/articles/urllib2.shtml
I've tried sending the image opened, eg "open(imgname, 'rb'), and
mime'd, according to this resource:
http://www.python.org/doc/2.2.3/lib/node397.html
Here is some python code and errors. Be sure to provide a twitter
username and password instead of XXX.
>>> username = XXX
>>> password = XXX
>>> url = 'http://twitter.com/account/update_profile_background_image.json'
>>> imgname = 'media/tcal/img/twitter_icon.jpg'
>>> fp = open(imgname, 'rb')
>>> img = MIMEImage(fp.read())
>>> fp.close()
>>> values = {'image':img }
>>> data = urllib.urlencode(values)
>>> auth = urllib2.HTTPPasswordMgrWithDefaultRealm()
>>> auth.add_password(None, 'http://twitter.com/account/', username, password)
>>> authHandler = urllib2.HTTPBasicAuthHandler(authHandler)
>>> opener = urllib2.build_opener(authHandler)
>>> opener.open(url, data)
