This gem contains the mixi strategy for OmniAuth.

mixi uses the OAuth2 server flow, you can read about it here: http://developer.mixi.co.jp/en/connect/mixi_graph_api/api_auth/

So let's say you're using Rails, you need to add the strategy to your Gemfile:

gem 'omniauth-mixi'

You can also pull them in directly from Github e.g.:

gem 'omniauth-mixi', git => 'https://github.com/mixi-inc/omniauth-mixi.git'

Then bundle install to install dependencies.

Once these are in, you need to add the following to your config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :mixi, 'consumer_key', 'consumer_secret'
end

You will obviously have to put in your key and secret, which you get when you register your app with Partner Dashboard.

When you define like the Builder above, you will retrieve basic user's informations. If you want to retrieve minimum information set only, the parameter :info_level can be used:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :mixi, 'consumer_key', 'consumer_secret', :info_level => :min
end

Now just follow the README at: https://github.com/intridea/omniauth

Here's an example Auth Hash available in request.env['omniauth.auth']:

{
  :provider => 'mixi',
  :uid => '1234567',
  :info => {
    :name => 'Yoichiro Tanaka',
    :first_name => 'Yoichiro',
    :last_name => 'Tanaka',
    :description => 'I am an engineer. And, ...',
    :location => 'Hasuda-shi, Saitama pref.',
    :nickname => 'Yoichiro',
    :urls => {
      :profile => 'http://mixi.jp/show_friend.pl?uid=1234567'
    },
    :image => 'https://profile.img.mixi.jp/1234567.jpg'
  },
  credentials => {
    :token => 'ABCDEFG...', # OAuth 2.0 access_token, which you may wish to store
    :refresh_token => 'HIJKLMN...',
    :expires_at => 1353854879, # when the access token expires (it always will)
    :expires => true
  },
  :extra => {
    :raw_info => {
      :addresses => [{
        :region => 'Saitama pref.',
        :type => 'location',
        :locality => 'Hasuda-shi'
      }],
      :thumbnailUrl => 'https://profile.img.mixi.jp/1234567.jpg',
      :aboutMe => 'I am an engineer. And, ...',
      :name => {
        :givenName => 'Yoichiro',
        :familyName => 'Tanaka'
      },
      :id => '1234567',
      :profileUrl => 'http://mixi.jp/show_friend.pl?uid=1234567',
      :displayName => 'Yoichiro'
    }
  }
}

The precise information available may depend on the permissions which you request.

This project includes an example application to try OmniAuth-mixi quickly. You can launch the example by the following commands:

$ cd example
$ bundle install
$ CLIENT_ID=[consumer_key] CLIENT_SECRET=[consumer_secret] rackup

Of course, you have to replace the two parameters [consumer_key] and [consumer_secret] to them issued for your application.

And, open http://localhost:9292/ in your browser, then you will see the authentication and authorization page of mixi.

OmniAuth mixi is tested under 1.8.7, 1.9.2, 1.9.3, 2.0.0, 2.1, 2.2 and JRuby.
