[web2py] `auth.login_bare` doesn't work with Unicode?

[Alec Taylor]

I have written a very simple function for testing auth; via REST:

@service.jsondef login():
    try:
        args = json.loads(request.body.read())
        username = HTMLParser.unescape.__func__(HTMLParser, args['user'])
        password = HTMLParser.unescape.__func__(HTMLParser, args['pass'])
        return dict(auth_succeeded=str(auth.login_bare(username, password)))
    except ValueError, KeyError:
        raise HTTP(400, 'Invalid data received')


Unfortunately this gives me the following traceback:

Traceback (most recent call last):
  File "web2py\gluon\restricted.py", line 212, in restricted

    mac = hmac.new(data, None, hashfunc)

    return HMAC(key, msg, digestmod)
  File "C:\usr\bin\Python27\lib\hmac.py", line 72, in __init__
    self.outer.update(key.translate(trans_5C))
TypeError: character mapping must return integer, None or unicode

How do I get this simple test-case working?

Thanks for all suggestions,

Alec Taylor
