「omniauth-twitter」電子郵件ID不是從軌道上的ruby中的twitter獲取的

Question

我使用omniauth-twitter gem在我的rails應用程序中啓用Twitter登錄。這裏是我的代碼...

的Gemfile -

gem 'omniauth', '~> 1.1.1' 
gem 'omniauth-twitter' 

的routes.rb -

match '/auth/twitter/callback', to: 'users#twitter_login' 
match 'auth/failure', to: 'static_pages#home' 

User_controller.rb -

 def twitter_login 
     auth = request.env['omniauth.auth'] 
     authentication = Authentication.find_by_provider_and_uid(auth['provider'],auth['uid']) 
     if authentication 
      sign_in authentication.user 
      redirect_to root_url 
     else 
     if(User.where(:email => auth['extra']['raw_info']['email']).exists?) 
      flash[:notice] = "You already have account in ibetter" 
      redirect_to root_url   
     else 
      user = User.new 
      user.apply_omniauth(auth)   
      if user.save(:validate => false)  
       sign_in user   
       flash[:notice] = "Welcome to Ginfy"   
       redirect_to root_url 
      else 
       flash[:error] = "Error while creating a user account. Please try again." 
       redirect_to root_url 
      end 
      end 
     end 
    end 

session_helper.rb -

def sign_in(user) 
    cookies.permanent[:remember_token] = user.remember_token 
    self.current_user = user 
    end 

User.rb模型 -

before_save { |user| user.email = email.downcase } 
    def apply_omniauth(auth) 
    self.email = auth['extra']['raw_info']['email'] 
    self.name = auth['extra']['raw_info']['name'] 
    authentications.build(:provider => auth['provider'], :uid => auth['uid'], :token => auth['credentials']['token']) 
    end 

ERB碼 -

<%= link_to image_tag("login-twitter.png", alt: "twitter"), "/auth/twitter",:class => "popup", :"data-width" => "600", :"data-height" => "400" %> 

電子郵件ID是不是從Twitter獲取。請幫助

Answer 1

Twitter不會通過API向您發送電子郵件。

如果您使用omniauth-facebook gem作爲例子，但是twitter不會爲您提供電子郵件，您就必須創建解決方法。

例如，請求用戶在第二步填寫他/她的電子郵件地址。

Answer 2

GEM工作正常，問題是Twitter因爲某些原因不需要return email。不像facebook ..

Answer 3

接受的答案已過時。 Twitter現在通過Special Permission Form提供電子郵件。填寫請求特殊權限的表單並等待批准。
