我一直在努力设置我的Omniauth for facebook我不知道我做错了什么.
我无法收到用户的电子邮件.返回的哈希只包含“name”和“uid”,甚至不包含“first_name”和“last_name”
devise.rb：
config.omniauth :facebook,"KEY","SECRET"
omniauth_callbacks_controller.rb：
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def facebook
logger.info request.env["omniauth.auth"]
@user = User.from_omniauth(request.env["omniauth.auth"])
sign_in_and_redirect @user
end
end
user.rb：
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable,:lockable,:timeoutable and :omniauthable
devise :database_authenticatable,:registerable,:recoverable,:rememberable,:trackable,:validatable,:omniauthable,:omniauth_providers => [:facebook]
has_many :authentications
def self.from_omniauth(auth)
logger.info auth
user = where(email: auth.info.email).first
if(user != nil)
user.authentications.where(provider: auth.provider,uid: auth.uid).first_or_create do |l|
user.authentications.create!(user_id: user.id,provider: auth.provider,uid: auth.uid)
end
else
user = User.create!(email: auth.info.email,password: Devise.friendly_token[0,20],first_name: auth.info.first_name,last_name: auth.info.last_name)
user.authentications.create!(user_id: user.id,uid: auth.uid)
end
user
end
end
registrations_controller.rb：
class RegistrationsController < Devise::RegistrationsController
private
def sign_up_params
params.require(:user).permit(:first_name,:last_name,:email,:password,:password_confirmation)
end
def account_update_params
params.require(:user).permit(:first_name,:password_confirmation,:current_password)
end
end
routes.rb中：
devise_for :users,:controllers => { registrations: 'registrations',omniauth_callbacks: 'omniauth_callbacks' }
返回哈希：
#<OmniAuth::AuthHash credentials=#<OmniAuth::AuthHash expires=true expires_at=1444504014 token="TOKEN"> extra=#<OmniAuth::AuthHash raw_info=#<OmniAuth::AuthHash id="1506781179612589" name="Ayman Salah">> info=# <OmniAuth::AuthHash::InfoHash image="http://graph.facebook.com/1506781179612589/picture" name="Ayman Salah"> provider="facebook" uid="1506781179612589">
解决方法
确保你没有在信息字段请求中放置空格(另一个答案可能是错误的).
您需要特别要求从info字段哈希返回电子邮件,因为它不是默认情况下.
如果您在没有Devise的情况下使用Omniauth-Facebook,请在config / initializers / omniauth.rb文件中进行设置,如下所示：
Rails.application.config.middleware.use OmniAuth::Builder do provider :facebook,Rails.application.secrets.omniauth_provider_key,Rails.application.secrets.omniauth_provider_secret,:scope => 'email',:display => 'popup',:info_fields => 'name,email' end
这个信息有点隐藏在omniauth-facebook gem的GitHub自述文件的Configuring部分的最后.
但是,使用Devise plus Omniauth,你可以在config / initializers / devise.rb中设置它(如果字符串中没有空格！)：
config.omniauth :facebook,'app_id','app_secret',scope: 'email',info_fields: 'name,email'
