OmniAuth Seznam.cz Strategy

Strategy to authenticate with Seznam.cz in OmniAuth.

Get your API key at: https://vyvojari.seznam.cz/oauth/admin Note the Client ID and the Client Secret.

For more details, read the Seznam.cz docs: https://vyvojari.seznam.cz/oauth

Add to your Gemfile:

gem 'omniauth-seznam-cz'

Then bundle install.

Here's an example for adding the middleware to a Rails app in config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :seznam_cz, ENV['SEZNAM_CLIENT_ID'], ENV['SEZNAM_CLIENT_SECRET']
end

You can now access the OmniAuth Seznam.cz URL: /auth/seznam_cz

NOTE: While developing your application, if you change the scope in the initializer you will need to restart your app server.

You can configure several options, which you pass in to the provider method via a hash:

• scope: A comma-separated list of permissions you want to request from the user.

• redirect_uri: Override the redirect_uri used by the gem.

Here's an example of an authentication hash available in the callback by accessing request.env['omniauth.auth']:

}
