用omniauthable设计twitter电子邮件

Question

我可以使用devise :omniauthable获取params twitter电子邮件吗?

我可以用这个方法获得facebook的电子邮件和创建用户:

def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
  data = access_token['extra']['user_hash']
  if user = User.find_by_email(data["email"])
    user
  else # Create a user with a stub password.
    User.create!(:email => data["email"], :password => Devise.friendly_token[0,20])
  end 
end

控制器:

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    @user = User.find_for_facebook_oauth(env["omniauth.auth"], current_user)
    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook"
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.facebook_data"] = env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
  def twitter
    @user = User.find_for_twitter_oauth(env['omniauth.auth'])
    if @user.persisted?
      flash[:notice] = I18n.t 'devise.omniauth_callbacks.success', :kind => 'Twitter'
      sign_in_and_redirect @user, :event => :authentication
    else
      flash[:notice] = I18n.t 'devise.omniauth_callbacks.failure', :kind => 'Twitter', :reason => 'User not found'
      redirect_to new_user_session_path
    end
  end
end

如果我在传入参数中使用像这样的twitter验证，我得到user_id, uid, credentials, secret等…但是没有电子邮件。我可以这样拿吗?我不想为用户表添加新字段，也不想添加带有用户id、oauth提供者和oauth id的新表。

twitter是否存在更干净的方法?

Twitter API 不返回电子邮件，所以这取决于你如何处理
