Most clever way to parse a Facebook OAuth 2 access token string
- by RyOnLife
It's a bit late, but I'm disappointed in myself for not coming up with something more elegant. Anyone have a better way to do this...
When you pass an OAuth code to Facebook, it response with a query string containing access_token and expires values.
access_token=121843224510409|2.V_ei_d_rbJt5iS9Jfjk8_A__.3600.1273741200-569255561|TxQrqFKhiXm40VXVE1OBUtZc3Ks.&expires=4554
Although if you request permission for offline access, there's no expires and the string looks like this:
access_token=121843224510409|2.V_ei_d_rbJt5iS9Jfjk8_A__.3600.1273741200-569255561|TxQrqFKhiXm40VXVE1OBUtZc3Ks.
I attempted to write a regex that would suffice for either condition. No dice. So I ended up with some really ugly Ruby:
s = s.split("=")
@oauth = {}
if s.length == 3
@oauth[:access_token] = s[1][0, s[1].length - 8]
@oauth[:expires] = s[2]
else
@oauth[:access_token] = s[1]
end
I know there must be a better way!
