I just looked at your code briefly, but I believe the problem is this line:
oauth_request = TwitpicOAuthRequest(http_method="POST", http_url=settings.TWITPIC_API_URL, The OAuth Request needs to be signed using the Twitter Endpoint (https://api.twitter.com/1/account/verify_credentials.json), not the Twitpic API URL. Try something like this: oauth_request = TwitpicOAuthRequest(http_method="GET", http_url="https://api.twitter.com/1/account/verify_credentials.json";, On Jun 3, 2:38 pm, yml <yann.ma...@gmail.com> wrote: > I would greatly appreciate any help. > Here it is the latest evolution of this piece of code : > > """ > class TwitpicOAuthRequest(OAuthRequest): > def to_header(self, realm='http://api.twitter.com/'): > headers = super(TwitpicOAuthRequest, > self).to_header(realm=realm) > return {'X-Verify-Credentials-Authorization': > headers['Authorization']} > > def post_photo(request): > if request.method == 'POST': > form = PhotoForm(request.POST, request.FILES) > if not request.session.get('twitter_access_token'): > return HttpResponse("Not authenticated") > if form.is_valid(): > access_token = request.session['twitter_access_token'] > > params = { > 'oauth_consumer_key': settings.TWITTER_CONSUMER_KEY, > 'oauth_signature_method':"HMAC-SHA1", > 'oauth_token':access_token.key, > 'oauth_timestamp':oauth.generate_timestamp(), > 'oauth_nonce':oauth.generate_nonce(), > 'oauth_version':'1.0' > } > > consumer = > oauth.OAuthConsumer(key=settings.TWITTER_CONSUMER_KEY, > > secret=settings.TWITTER_CONSUMER_SECRET) > token = oauth.OAuthToken(key=access_token.key, > secret=access_token.secret) > oauth_request = TwitpicOAuthRequest(http_method="GET", > > #http_url=settings.TWITPIC_API_URL, > > http_url=settings.TWITTER_VERIFY_CREDENTIALS, > parameters=params) > > signature=oauth_request.sign_request(OAuthSignatureMethod_HMAC_SHA1(), > consumer, > access_token) > > headers = oauth_request.to_header() > headers['X-Auth-Service-Provider'] = > settings.TWITTER_VERIFY_CREDENTIALS > > #with multipart_encode > values = [ > MultipartParam('key',value=settings.TWITPIC_API_KEY), > > MultipartParam('message',value=form.cleaned_data['message']), > MultipartParam('media', > filename='copine_moi.jpg', > filetype='image/jpeg', > fileobj=open("/home/yml/Desktop/ > copine_moi.jpg","rb")) > ] > > register_openers() > datagen, heads = multipart_encode(values) > headers.update(heads) > req = urllib2.Request(settings.TWITPIC_API_URL, datagen, > headers) > #
