omniauth twitter

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET']
end
出現 http 400 錯誤 ， 結果

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter, 'TWITTER_KEY', 'TWITTER_SECRET'
end
這樣就過了.........................................................................
