flask-mwoauth 0.4.82

Flask blueprint to connect to a MediaWiki OAuth server

flask-mwoauth

Flask blueprint to run OAuth against MediaWiki's extension:OAuth.

Note: The python-mwoauth library is more actively maintained, and also contains basic flask support. Please consider using python-mwoauth directly if it supports your use case.

The blueprint adds these uris:

• /login - runs the OAuth handshake and returns the user to /
  • /login?next=/someurl will return the user to /someurl
• /logout - clears the users' access tokens
  • /logout?next=/someurl will return the user to /someurl
• /oauth-callback - callback from MW to finish the handshake

The users' OAuth key and secret are stored in the session.

In addition, flask-mwoauth adds a few convenience functions:

1. get_current_user(cached=True) reports who the current user is. To confirm the user is still logged in (e.g. tokens have not been revoked), call it with cached=False.

2. request(api_query) submits an request through the API, using the users' access tokens. For instance,

result = request({'action': 'query', 'meta': 'userinfo'})

fetches https://www.mediawiki.org/w/api.php?action=query&meta=userinfo and returns the result as Python dict, e.g.

{u'batchcomplete': u'', u'query': {u'userinfo': {u'id': 31344, u'name': u'Valhallasw'}}}

If you are authorized to access other wikis (e.g. en.wikipedia.org, although you authorized via mediawiki.org), you can run a request there using

result = request({'action': 'query', 'meta': 'userinfo'}, url='https://en.wikipedia.org/w/api.php')

For more information on using the api, please check the api documentation at https://www.mediawiki.org/wiki/API:Main_page

The example app

An example app is implemented in demo.py.

1. Go to https://meta.wikimedia.org/wiki/Special:OAuthConsumerRegistration/propose and fill in the following values:

• Application name: test app
• Application description: test app for flask-mwoauth
• OAuth "callback" URL: http://localhost:5000/oauth-callback
• Contact email address:
• Leave all other values default.

2. Click 'Propose consumer'. You now get a message stating

Your OAuth consumer request has been received.

You have been assigned a consumer token of and a secret token of . Please record these for future reference."

3. Then

   $ python setup.py develop
   $ python demo.py
   NOTE: The callback URL you entered when proposing an OAuth consumer
   probably did not match the URL under which you are running this development
   server. Your redirect back will therefore fail -- please adapt the URL in
   your address bar to http://localhost:5000/oauth-callback?oauth_verifier=...etc
   
   Consumer key: <the consumer key you got>
   Consumer secret: <the consumer secret you got>
   

   You may need to re-enter the key and secret if the app reloads.

4. Go to http://localhost:5000/ and click 'login'.
