I have a feeling that this topic comes up often, but I cannot seem to
Google a good solution to this. Essentially, I want users to be able to
login using either the built in Auth, or login via some Oauth provider,
like Twitter and Facebook. I have seen previous solutions using
ExtendedLoginForm and custom Twitter classes that inherit from
OAuthProvider, but they no longer seem to work. The Twitter code I find no
longer supports the newest Twitter API; the linkedin code from the web2py
book also does not work.
Here is sample code I have now, which only seems to constantly redirect me
to the logout page:
1) Created new web2py application by copying the welcome one to a folder
named 'oauth'
2) Added this code to db.py (taken from multiple examples online):
from gluon.contrib.login_methods.oauth10a_account import OAuthAccount
from oauth2 import Client, Consumer, Token
class TwitterAccount(OAuthAccount):
AUTH_URL = "http://twitter.com/oauth/authorize";
TOKEN_URL = "https://twitter.com/oauth/request_token";
ACCESS_TOKEN_URL = "http://twitter.com/oauth/access_token";
CLIENT_ID = "..."
CLIENT_SECRET = "..."
def __init__(self, g):
OAuthAccount.__init__(self, g, self.CLIENT_ID, self.CLIENT_SECRET,
self.AUTH_URL, self.TOKEN_URL, self.ACCESS_TOKEN_URL)
def get_user(self):
if self.accessToken() is not None:
consumer = Consumer(key=self.CLIENT_ID,
secret=self.CLIENT_SECRET)
client = Client(consumer, self.accessToken())
resp, content =
client.request('http://api.twitter.com/1/account/verify_credentials.json')
if resp['status'] != '200':
# cannot get user info. should check status
#redirect("http://google.com";)
return None
u = json.loads(content)
return dict(first_name = u['name'], username=u['screen_name'],
name=u['name'], registration_id=u['id'])
auth.settings.login_form=TwitterAccount(g=globals())
3) Going to 127.0.0.1/oauth/user/login redirects me to user/logout.
Besides my frustration in trying to find timely information about this, is
there working code out there that is *recent*, in that it works with latest
web2py and the latest Oauth implementations? I'd really appreciate any tips
or hints anyone has.
