"""Create an OAuth10aDance object to negotiatie OAuth 1.0a credentials.
The first set of parameters are the URLs to the OAuth 1.0a service
you wish to authenticate against.
:param req_token: Request token URL
:param authorize: User authorization URL
:param acc_token: Access token URL
These parameters (and the others) may also be provided by subclassing
the OAuth10aDance class, eg:
:Example:
>>> class OAuthDanceTwitter(beanbag.OAuth10aDance):
... req_token = "https://api.twitter.com/oauth/request_token"
... authorize = "https://api.twitter.com/oauth/authorize"
... acc_token = "https://api.twitter.com/oauth/access_token"
The second set of parameters identify the client application to
the server, and need to be obtained outside of the OAuth protocol.
:param client_key: client/consumer key
:param client_secret: client/consumer secret
The final set of parameters identify the user to server. These
may be left as None, and obtained using the OAuth 1.0a protocol
via the ``obtain_creds()`` method or using the ``get_auth_url()``
and ``verify_user()`` methods.
:param user_key: user key
:param user_secret: user secret
Assuming OAuthDanceTwitter is defined as above, and you have
obtained the client key and secret (see https://apps.twitter.com/
for twitter) as ``k`` and ``s``, then putting these together
looks like:
:Example:
>>> oauthdance = OAuthDanceTwitter(client_key=k, client_secret=s)
>>> oauthdance.obtain_creds()
Please go to url:
https://api.twitter.com/oauth/authorize?oauth_token=...
Please input the verifier: 1111111
>>> session = requests.Session()
>>> session.auth = oauthdance.oauth()
