omniauth OAuthException & OAuth::Unauthorized - ruby-on-rails

Question

I have installed omniauth 1.0. Also I have oauth-0.4.5, oauth2-0.5.1, omniauth-facebook-1.0.0, omniauth-twitter-0.0.6.
omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
provider :developer unless Rails.env.production?
provider :facebook, ENV['167257285348131'], ENV['c8c722f697scb2afcf1600286c6212a9'], :scope => 'email,offline_access,read_stream', :display => 'popup'
provider :twitter, ENV['fma2L22ObJCW52QrL7uew'], ENV['4aZfhCAOdiS7ap8pHJ7I1OZslFwVWWLiAMVpYUI']
end
session_controller.rb
class SessionsController < ApplicationController
require 'omniauth-facebook'
require 'omniauth-twitter'
require 'omniauth'
def create
#user = User.find_or_create_from_auth_hash(auth_hash)
self.current_user = #user
redirect_to '/'
end
def auth_hash
request.env['omniauth.auth']
end
end
Also I add
'omniauth'
'omniauth-facebook'
'omniauth-twitter' gems to gemfile
There are two problems:
When I go http://localhost:3000/auth/facebook I get
{
"error": {
"message": "Missing client_id parameter.",
"type": "OAuthException"
}
}
And the link graph.facebook.com/oauth/authorize?response_type=code&client_id=&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Ffacebook%2Fcallback&parse=query&scope=email%2Coffline_access%2Cread_stream&display=popup
And there is no client_id!!!
When I go to http://localhost:3000/auth/twitter I get OAuth::Unauthorized
401 Unauthorized
Any ideas?

Answer 1

Alex D. is correct in that the ENV[] breaks it. To create omniauth.rb so that it uses different keys in different environments just put:
provider :twitter, TWITTER_KEY, TWITTER_SECRET
in omniauth.rb
and then in your environment config files (config/environments/development.rb, etc.) put the key you want to use for that environment.
config/environments/development.rb:
TWITTER_KEY = 'aaaaaaa'
TWITTER_SECRET = 'aaaabbbbbb'
config/environments/production.rb:
TWITTER_KEY = 'ccccccc'
TWITTER_SECRET = 'ccccdddddd'

Answer 2

ENV['something']
looks into your environment vars for "something", so it would expect
something='12345'
so you should do it like that
export AUTH_FB_KEY='....'
export AUTH_FB_SECRET='...'
check with
env
and update your config
provider :facebook, ENV['AUTH_FB_KEY'], ENV['AUTH_FB_SECRET']
if you use heroku
heroku config:add AUTH_FB_KEY='....'

There have been breaking changes made in omniauth 1.0 - https://github.com/intridea/omniauth
OmniAuth 1.0 has several breaking changes from version 0.x. You can
set the dependency to ~> 0.3.2 if you do not wish to make the more
difficult upgrade. See the wiki for more information.
I would try reverting omniauth to 0.3.2:
gem install omniauth --version '~> 0.3.2'
or if you're using bundler, in your Gemfile:
gem omniauth, '~> 0.3.2'
