我是 Rails 新手...我正在尝试设置使用 facebook 登录以获取演示应用程序。我正在使用 OmniAuth 并遵循本教程
https://github.com/plataformatec/devise/wiki/OmniAuth:-概述
重定向到 fB 时出现此错误:
Routing Error:
uninitialized constant Users
Try running rake routes for more information on available routes.
环境
Windows 7
Rails version :3.2.9.rc2
omniauth-1.1.1
devise-2.1.2
我的 routes.rb 看起来像这样:
root :to => 'static_pages#home'
resources :users
get "static_pages/home"
match '/auth/facebook' => 'omniauth#passthru'
match '/users/auth/facebook' => 'users/omniauth_callbacks#passthru'
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } , :strategy_class => OmniAuth::Strategies::Facebook
devise.rb 包含:
require 'devise/orm/active_record'
require 'omniauth-facebook'
config.omniauth_path_prefix = "/users/auth"
config.omniauth :facebook, "ABC", "XYZ",{:client_options => { :ssl => { :verify => false } }}
而OmniAuthController包含:即app/controllers/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.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)
if @user.persisted?
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
session["devise.facebook_data"] = request.env["omniauth.auth"]
#redirect_to new_user_registration_url
redirect_to "static_pages_home"
end
end
def passthru
render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false
# Or alternatively,
# raise ActionController::RoutingError.new('Not Found')
end
end
模型 User.rb 包含:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me
attr_accessible :date_of_birth, :firstName, :lastName, :mailId, :phone, :provider, :uid
devise :omniauthable
protected
def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
user = User.find(:provider => auth.provider, :uid => auth.uid).first
unless user
user = User.create(name:auth.extra.raw_info.name,
provider:auth.provider,
uid:auth.uid,
email:auth.info.email,
password:Devise.friendly_token[0,20]
)
end
user
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
痕迹:
在 2012-11-23 22:39:32 -0800 (facebook) 开始为 127.0.0.1 获取“/users/auth/facebook”(facebook)回调阶段已启动。
开始 GET "/users/auth/facebook/callback?
state=XYZ&code=ABC" for 127.0.0.1 at 2012-11-23 22:39:33 -0800
