[web2py] Re: 'Morsel' object has no attribute 'split' ?
Hey web2py_tn,
I don't know if you still need this but I recently battled this problem
myself and here is a solution I'd like to leave here so others don't need
to battle with this too.
If you're using the web2py_multiauth first apply this patch:
http://code.google.com/p/cfhowes/issues/detail?id=2
Then overwrite these 2 functions in facebook.py to:
def parse_signed_request(signed_request, application_secret_key):
"""Parse a signed request, returning a dictionary describing its
payload."""
def decode(encoded):
padding = '=' * (len(encoded) % 4)
return base64.urlsafe_b64decode(encoded + padding)
try:
encoded_signature, encoded_payload = (str(string) for string in
signed_request.split('.', 2))
signature = decode(encoded_signature)
signed_request_data = json.loads(decode(encoded_payload))
except (TypeError, ValueError):
raise Exception("Signed request had a corrupt payload")
if signed_request_data.get('algorithm', '').upper() != 'HMAC-SHA256':
raise Exception("Signed request is using an unknown algorithm")
expected_signature = hmac.new(application_secret_key,
msg=encoded_payload, digestmod=hashlib.sha256).digest()
if signature != expected_signature:
raise Exception("Signed request signature mismatch")
return signed_request_data
def get_user_from_cookie(cookies, app_id, app_secret):
"""Parses the cookie set by the official Facebook JavaScript SDK.
cookies should be a dictionary-like object mapping cookie names to
cookie values.
If the user is logged in via Facebook, we return a dictionary with the
keys "uid" and "access_token". The former is the user's Facebook ID,
and the latter can be used to make authenticated requests to the Graph
API.
If the user is not logged in, we return None.
Download the official Facebook JavaScript SDK at
http://github.com/facebook/connect-js/. Read more about Facebook
authentication at http://developers.facebook.com/docs/authentication/.
"""
cookie = cookies.get("fbsr_" + app_id, "")
if not cookie:
return None
response = parse_signed_request(cookie.value, app_secret)
if not response:
return None
args = dict(
code = response['code'],
client_id = app_id,
client_secret = app_secret,
redirect_uri = '',
)
file = urllib.urlopen("https://graph.facebook.com/oauth/access_token?";
+ urllib.urlencode(args))
try:
token_response = file.read()
finally:
file.close()
access_token = cgi.parse_qs(token_response)["access_token"][-1]
return dict(
uid = response["user_id"],
access_token = access_token,
)
The key change here is in get_user_from cookie where
"parse_signed_request(cookie, app_secret)" changed to
"parse_signed_request(cookie.value, app_secret)"

Hey Ben- Can you share your version of facebook.py?

[web2py] Re: 'Morsel' object has no attribute 'split' ?
It seemed that version of facebook.py that I was using is just incompatible and/or outdated get_user_from_cookie() was trying to parse a cookie variable out that did not exist from facebook. I ended up passing the correct cookie variable directly in and changing a couple lines to prove that that was the problem. When I ran into other issues it seemed best just to write my own version of facebook.py as I needed certain functions.

Cant't you just modify the interface code to get the expected string
input? It seems that the input data is stored in the Morsel instance.
