Problems passing access token to authenticate with API

问题

I'm trying to get information from the Gimmebar API (redirects to the access token step) and having problems with the last step exchanging the access token for the data.

#getting access token successfully before this
post_url = '/tags'
headers = {'Authorization': 'Bearer %s' % access_token}
query = '/collections'
full_url = '%s%s%s' % (base_url, post_url, query)
req = urllib2.Request(full_url, headers=headers)
response = urllib2.urlopen(req)
the_page = response.read()

It breaks at the urllib2.Request and I'm getting an error that I'm not sure what to do with:

No exception supplied

Exception Location: /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib2.py in http_error_default, line 510

Here is the view so you can see how I got to step5...
