Problem

I'm getting the following error:

"error": {
      "message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration.",
      "type": "OAuthException",
      "code": 191
   }

It is very known and I found many different solutions to adress it and unfortunatelly any of them worked for me.

I'm trying to make it run locally in the localhost:3000, but can't make it work.

My configuration is a common configuration:

config/initializers/devise.rb

config.omniauth :facebook, '396783260390829', 'a504939e60c3410ed1becc44f41d4b94', {client_options: {ssl: {ca_file: Rails.root.join('lib/assets/cacert.pem').to_s}}}

Facebook config:

enter image description here

Routes.rb

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

devise_scope :user do
  get '/users/auth/:provider' => 'users/omniauth_callbacks#passthru'
end

I already tried the following approaches:

Approach 1:

OmniAuth.config.full_host = '`http://localhost:3000/`'

This one was the closest I got, because it redirect me back, but the adress was http://localhost:3000//users/auth/facebook/callbacks?xxx

I already tried without the last slash OmniAuth.config.full_host = 'http://localhost:3000', but then I got the 191.

Approach 2

Normal initializer, without the hack.

Approach 3

Set the domain in the Facebook configuration page.

Approach 4

Set App Domains to localhost

Approach 5

Set the Web Site in Facebook configuration to http://localhost:3000/users/auth/facebook

Approach 6

Tryied with my ip adress instead of localhost and got the same error, but pnot in the failure of OmniauthCallbacksController, but in the graph.facebook.com/oauth/authorize?

redirect_uri=http://localhost:3000/users/auth/facebook/callback

Result for all approaches

In all the cases except the ones I explained inline I got

OAuthException 191

in the failure method of OmniauthCallbackController I created to handle the callback.

Please if you know other alternatives or want to see anything else to try to help me, feel free to ask or answer.

    You must be following some really old tutorials as the omniauth configuration with devise is done in a completely different way. Take a look at the wiki of the project, if you follow it to the letter you'll get the job done. https://github.com/plataformatec/devise/wiki/OmniAuth%3A-Overview – Ashitaka Nov 09 '12 at 02:09
  • Actually I took my configuration exactly from the wiki you linked, the only difference is OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE that i use to ignore ssl – felipeclopes Nov 09 '12 at 02:12
  • But you have an `omniauth.rb` file! That does not appear on that wiki and you shouldn't need that. – Ashitaka Nov 09 '12 at 02:16
  • If you want to post as an answer I'll accept it. Thank you, it worked. – felipeclopes Nov 09 '12 at 03:13
  • The solution should be posted as an answer, not as part of the question. You can post answers to your own questions and accept them. – Rimian Mar 31 '13 at 16:56

Facebook does not allow the redirect address to be localhost. You must use a real IP address or named address. See answer to similar question: Facebook app - login through omniauth - OAuthException 191

Solution

As mentioned by @AshitakaI had to remove my old and deprecated omniauth.rb, so my final and working configuration is the following one:

config/initializers/devise.rb

In order to make authentication works I copied the cacert to my assets and referenced in the devise.rb

config.omniauth :facebook, 'xxxxxxxxxxxxxxx', 'a504xxxe60cxxxxed1bexxxxf41d4b94', {client_options: {ssl: {ca_file: Rails.root.join('lib/assets/cacert.pem').to_s}}}

Facebook config:

Link to Facebook auth

/users/auth/facebook

Thank you for the help, this issue took me 5 hours to solve.
