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!!
+ - session = {
+ - "access_token": args["access_token"][-1],
+ - "expires": args.get("expires")
