New submission from arexus <asweene...@gmail.com>:
When following the 2-legged flow example provided I am experiencing the
following error:
TypeError: character mapping must return integer, None or unicode
This is caused by a unicode string being passed to the HMAC(...) function. I
have
traced everything back to the root of the problem and it turns out that this is
caused by using a sqlite database with sqlalchemy.
http://www.sqlalchemy.org/docs/dialects/sqlite.html#unicode
What happens is:
cons = Consumer()
cons.key = 'test'
cons.secret = 'test'
cons.name = 'test'
Session.add(cons)
Session.commit()
type(cons.key) will become unicode.
A really poor workaround is to add the following to to the
get_consumer_by_key()
function:
cons = self.DBSession.query(self.Consumer).filter_by(key=key).first()
cons.key.encode('ascii')
cons.secret.encode('ascii')
A better solution may be to store the key and string as binary.
