我按照 Omniauth 演练中的所有说明进行操作。
请注意,我的用户模型没有名称或图像属性。
我按照 Rails 教程中的说明进行操作。但是,我确实必须改变这一点:
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]
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
user.name = auth.info.name # assuming the user model has a name
user.image = auth.info.image # assuming the user model has an image
end
end
def self.new_with_session(params, session)
super.tap do |user|
if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["raw_info"]
user.email = data["email"] if user.email.blank?
end
end
end
end
对此:
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]
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
# user.name = auth.info.name # assuming the user model has a name
# user.image = auth.info.image # assuming the user model has an image
end
end
def self.new_with_session(params, session)
super.tap do |user|
if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["raw_info"]
user.email = data["email"] if user.email.blank?
end
end
end
end
- 因为用户没有
name
或image
属性而引发错误。这导致了一个新错误:在 Omniauth_callbacks_controller 中创建的 @user 没有持久化,因此我没有登录,而是被重定向回用户注册页面。
omniauth_callbacks_controller.rb:
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def facebook
# You need to implement the method below in your model (e.g. app/models/user.rb)
@user = User.from_omniauth(request.env["omniauth.auth"])
puts "BEFORE IF STATEMENT"
puts @user.inspect
if @user.persisted?
puts "INSIDE IF STATEMENT"
sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
puts "AFTER ELSE STATEMENT"
session["devise.facebook_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
end
服务器读出,其中包括puts
语句和@user 对象。你会看到它的大部分字段都是 nil:
