OmniAuth YahooJp

These notes are based on master, please see tags for README pertaining to specific releases.

This is the official OmniAuth strategy for authenticating to Yahoo! JAPAN( YConnect ). To use it, you'll need to sign up for a YConnect Client ID and Secret on the Yahoo! JAPAN Developer Network.

Supports OAuth 2.0 Authorization Code flows. Read the Yahoo!JAPAN docs for more details: https://developer.yahoo.co.jp/yconnect/v2/

Add to your Gemfile:

gem 'omniauth-yahoojp'

Then bundle install.

OmniAuth::Strategies::YahooJp is simply a Rack middleware. Read the OmniAuth docs for detailed instructions: https://github.com/intridea/omniauth.

YConnect API v2 lets you set scopes to provide granular access to different types of data:

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :yahoojp, ENV['YAHOOJP_KEY'], ENV['YAHOOJP_SECRET'], 
    {
        scope: "openid profile email address"
    }
end

You can also set :display, :prompt, :scope, :bail parameter to specify behavior of sign-in and permission page. More info on YConnect.

For example, to request openid, profile, and email permissions and display the authentication page in a popup window:

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :yahoojp, ENV['YAHOOJP_KEY'], ENV['YAHOOJP_SECRET'], 
    {
        scope: "openid profile email",
        display: "popup"
    }
end

OmniAuth YahooJp uses versioned API endpoints by default (current v2). You can configure a different version via client_options hash passed to provider, specifically you should change the version in the site and authorize_url parameters. For example, to change to v1:

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :yahoojp, ENV['YAHOOJP_KEY'], ENV['YAHOOJP_SECRET'], 
    {
        scope: "openid profile email address",
        client_options: {
            authorize_url: '/yconnect/v1/authorization',
            token_url: '/yconnect/v1/token'
        }
    }
end
