Mosts FB Requests broken after upgrade to 0.5.0 #68

One of the main problems is that the automatic parser is not working anymore. The key :automatic does not exist from what I see making access_token requests pretty broken.

Line 127 in client.rb cannot work now from what I understand as the parsing is busted.
raise unless response.parsed.is_a?(Hash) && response.parsed['access_token']

This makes integration with Facebook much more verbose than needed.

Secondly it seems as most token_url's now have to be added while calling which was not the case before.

Any updates on when these can be fixed?


I have same problems, when trying to access users's data recieve following trace:

/home/deteam/.rvm/rubies/ruby-1.8.7-p302/lib/ruby/gems/1.8/gems/oauth2-0.5.0/lib/oauth2/client.rb:107:in `request'
/home/deteam/.rvm/rubies/ruby-1.8.7-p302/lib/ruby/gems/1.8/gems/oauth2-0.5.0/lib/oauth2/client.rb:127:in `get_token'
/home/deteam/.rvm/rubies/ruby-1.8.7-p302/lib/ruby/gems/1.8/gems/oauth2-0.5.0/lib/oauth2/strategy/auth_code.rb:28:in `get_token'

I concur with this. I get the same error as DeTeam


Also seeing this


Dug a bit deeper:

OAuth2 is still a draft specification (right now at v22), and changes over time. One of the changes made was that the Authorization header containing the bearer token should not start with "OAuth " but with "Bearer ". See (note: this article doesn't discuss any of Facebook specific stuff, just OAuth2 in general). The default name was changed in the gem in 5493f20 . Facebook however has not updated (yet) and still expects the header to start with "OAuth "

So basically this is not a bug.

To fix, simply pass the correct format to the AccessToken#initialize method, access_token_string, {:header_format => 'OAuth %s'})

One other thing I ran into, is that in 0.3.0 it was possible to do:

response_body_string = token.request(*args)

In 0.5.1, one needs to explicitly request the body

response_body_string = token.request(*args).body

@reinhrst this ok for me when I use:


But when I try to use:'/me/feed', :message => "hi, I'm posting a message from ruby")

Receive the same error:

OAuth2::Error: OAuth2::Error
from /Users/willywg/.rvm/gems/ruby-1.9.3-p0/gems/oauth2-0.5.2/lib/oauth2/client.rb:107:in `request'

OK, I don't think I ever tried it with posts... I don't have access to my facebook code anymore, so can't test it for you.

If I were you I would check if post indeed sends the correct header now (with OAuth in stead of Bearer).

Also, there are about a million other reasons why you may get an OAuth2::Error. Make sure you see what Facebook is actually sending you back (it may just be that your token is not allowed to post...)


Is this fixed in the latest version?
