Omniauth Facebook 不返回电子邮件和性别栏 4

我需要从 Facebook 获取姓名、电子邮件、图像和性别。我正在获取姓名和图像，但电子邮件和性别不是从 Facebook 获取的。我这两天都在苦苦挣扎，谁能帮帮我。

用户模型：

def self.from_omniauth(auth)
  where(provider: auth.provider, uid: auth.uid).first_or_initialize.tap do |user|       
    user.provider = auth.provider
    user.uid = auth.uid
    user.name = auth.info.name
    user.email = auth.info.email
    user.gender = auth.extra.raw_info.gender #if user.gender.blank?
    user.image = auth.info.image        
    user.save!
  end
end

Omniauth.rb

OmniAuth.config.logger = Rails.logger    
Rails.application.config.middleware.use OmniAuth::Builder do

if Rails.env.production?
  provider :facebook, 'APP_ID', 'APP_SEC'
elsif Rails.env.development?
  provider :facebook, 'APP_ID', 'APP_SEC', {:scope => 'publish_actions,email', :client_options => { :ssl => { :ca_file => "#{Rails.root}/config/ca-bundle.crt" }}}
else  
  provider :facebook, 'APP_ID', 'APP_SEC'
end  
end

如果我使用user.gender = auth.extra.raw.gender if user.gender.blank?它返回一个空值。

即使我已经检查过我的 Facebook 隐私设置，它也仅在公开个人资料中。有人可以帮我吗

添加这些更改以获取数据：

provider :facebook, 'APP_ID', 'APP_SEC_KEY', {:scope => 'email', :info_fields => 'email,name,first_name,last_name,gender', :client_options => { :ssl => { :ca_file => "#{Rails.root}/config/ca-bundle.crt" }}}
