Public bug reported:
tornado.auth.FacebookGraphMixin crashes when receiving the access token
from facebook.
On Ubuntu 17.04, tornado version 4.4.2-1ubuntu1
The problem seems to be at line 983 of
/usr/lib/python2.7/dist-packages/tornado/auth.py.
Replacing urlparse.parse_qs with escape.json_decode seems to fix the
problem:
- args = urlparse.parse_qs(escape.native_str(response.body))
+ args = escape.json_decode(escape.native_str(response.body)) #bug:
response is a json string!!
Here's the traceback:
