Question

本地一切正常，所以我将代码推送到heroku但是当我尝试使用Twitter验证用户时出现此错误。我正在使用omniauth进行身份验证。

schema.db

create_table "users", :force => true do |t|
    t.string    "name"
    t.string    "email"
    t.timestamp "created_at",                         :null => false
    t.timestamp "updated_at",                         :null => false
    t.string    "password_digest"
    t.string    "remember_token"
    t.string    "image"
  end

我将每个用户的个人资料图片网址拉到“图片”

下的字符串中

在user.rb内部

 def apply_omniauth(omniauth)
 authentications.build(:provider => omniauth['provider'],
 :uid => omniauth['uid'],
 :token => omniauth['credentials'].token,
 :secret => omniauth['credentials'].secret)
 @called_omniauth = true
 self.email = SecureRandom.urlsafe_base64(6)+"@testemail.com"
 self.name = omniauth['info']['nickname']
 self.password = self.password_confirmation = SecureRandom.urlsafe_base64(8)
 self.image = omniauth['info']['image']
 end

这是上面的self.image代码行。

这是heroku日志

身份验证控制器

 def create
  omniauth = request.env['omniauth.auth']
  authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
  if authentication
     user = User.find(authentication.user_id)
     sign_in_and_redirect user
  elsif current_user
   token = omniauth['credentials']['token']
   secret = omniauth['credentials']['secret']
   current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'], :token => token, :secret => secret)
   current_user.update_attribute(:image, omniauth['info']['image'])
   sign_in_and_redirect current_user
   else
    user = User.new
    user.apply_omniauth(omniauth)
    if user.save!
    sign_in_and_redirect User.find(user.id)
   else
    session[:omniauth] = omniauth.except('extra')
    redirect_to '/signup'
   end
end
end
