OmniAuth Deezer

Deezer API V2 Strategy for OmniAuth 1.0.

Supports the OAuth-like Deezer API V2 server-side flow. Read the Deezer docs for more details: http://www.deezer.com/en/developers/simpleapi/oauth

Installing

Add to your Gemfile:

gem 'omniauth-deezer'

Then bundle install.

Usage

OmniAuth::Strategies::Deezer is a plugin to OmniAuth 1.0. See Omniauth docs for more information : https://github.com/intridea/omniauth.

Add to your Gemfile:

gem 'omniauth-facebook'

Then run bundle install.

Create an app on Deezer website and save your app id and app secret.

In your Rack application, for instance in your Rails application, add the following lines in config/initializers/omniauth.rband use your app id and secret.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :deezer, ENV['DEEZER_APP_ID'], ENV['DEEZER_APP_SECRET'], :perms => 'basic_access,email'
end

Like omniauth-facebook, if you get the following error when redirected back from Deezer :

OpenSSL::SSL::SSLError (SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed)

You need to point your app to your SSL certificates directory :

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :deezer, ENV['DEEZER_APP_ID'], ENV['DEEZER_APP_SECRET'], :perms => 'basic_access,email', :client_options => {:ssl => {:ca_path => '/etc/ssl/certs'}}
end

Then change your routes in your application config/routes.rb

OmniauthTest::Application.routes.draw do
  match 'auth/deezer/callback' => 'sessions#create'
  match 'auth/failure' => 'errors#login_failed'
end

Then start your app and point your browser to /auth/deezer

Configuring

You can only configure :

• perms: A comma-separated list of permissions you want to request from the user. See the Deezer docs for a full list of available permissions: http://www.deezer.com/en/developers/simpleapi/oauth. Default: basic_access
