Rails 4，Devise，Omniauth（与多个提供者）

Question

我花了几天在devise和omniauth上观看RailsCasts，然后通过相关教程来设置使用这些gem的认证系统。我认为RailsCasts已经过时了，并且试图用其他教程来弥补差距正在创造各种问题。

请任何人都可以提出一个当前的教程，我可以用它作为实现这个系统的基础。我有单独的用户和身份验证模型（用户具有许多身份验证）。

我真的很喜欢在rails 4上使用devise和omniauth（CanCan的能力），但在试图找到一个基本设置（使用psql作为数据库）时，我的头发已经褪去。

在你初始化

Answer 1

东西要使用设计不同，需要1多个模型的多个身份验证提供者 - 授权

#authorization.rb 

# == Schema Information 
# 
# Table name: authorizations 
# 
# id   :integer   not null, primary key 
# user_id  :integer 
# provider  :string(255) 
# uid   :string(255) 
# token  :string(255) 
# secret  :string(255) 
# created_at :datetime 
# updated_at :datetime 
# profile_page :string(255) 
# 

class Authorization < ActiveRecord::Base 
    belongs_to :user 
end 

有代码用户模型

#user.rb 

SOCIALS = { 
    facebook: 'Facebook', 
    google_oauth2: 'Google', 
    linkedin: 'Linkedin' 
} 


has_many :authorizations 

def self.from_omniauth(auth, current_user) 
    authorization = Authorization.where(:provider => auth.provider, :uid => auth.uid.to_s, 
             :token => auth.credentials.token, 
             :secret => auth.credentials.secret).first_or_initialize 
    authorization.profile_page = auth.info.urls.first.last unless authorization.persisted? 
    if authorization.user.blank? 
    user = current_user.nil? ? User.where('email = ?', auth['info']['email']).first : current_user 
    if user.blank? 
     user = User.new 
     user.skip_confirmation! 
     user.password = Devise.friendly_token[0, 20] 
     user.fetch_details(auth) 
     user.save 
    end 
    authorization.user = user 
    authorization.save 
    end 
    authorization.user 
end 

def fetch_details(auth) 
    self.name = auth.info.name 
    self.email = auth.info.email 
    self.photo = URI.parse(auth.info.image) 
end 

，并在结束时，你需要重写为设计控制器

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController 

    def all 
    user = User.from_omniauth(env['omniauth.auth'], current_user) 
    if user.persisted? 
     sign_in user 
     flash[:notice] = t('devise.omniauth_callbacks.success', :kind => User::SOCIALS[params[:action].to_sym]) 
     if user.sign_in_count == 1 
     redirect_to first_login_path 
     else 
     redirect_to cabinet_path 
     end 
    else 
     session['devise.user_attributes'] = user.attributes 
     redirect_to new_user_registration_url 
    end 
    end 

    User::SOCIALS.each do |k, _| 
    alias_method k, :all 
    end 
end 

方法，如果你需要一些对供应商，例如Twitter你需要重写twitter方法，因为它不提供用户邮件，你应该以其他方式保存它的credentails。

你也应该在路线

devise_for :users, 
      :controllers => { 
      :omniauth_callbacks => 'users/omniauth_callbacks', 
      }

尝试做这样的

#config/initializers/devise.rb 
    #provider1 
    config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET'], 
    :site => 'https://graph.facebook.com/', 
    :authorize_path => '/oauth/authorize', 
    :access_token_path => '/oauth/access_token', 
    :scope => 'email, user_birthday, read_stream, read_friendlists, read_insights, read_mailbox, read_requests, xmpp_login, user_online_presence, friends_online_presence, ads_management, create_event, manage_friendlists, manage_notifications, publish_actions, publish_stream, rsvp_event, user_about_me, user_activities, user_birthday, user_checkins, user_education_history, user_events, user_groups, user_hometown, user_interests, user_likes, user_location, user_notes, user_photos, user_questions, user_relationships, user_relationship_details, user_religion_politics, user_status, user_subscriptions, user_videos, user_website, user_work_history' 

    #provider2 
    config.omniauth :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET'], 
    :scope => { 
    :secure_image_url => 'true', 
    :image_size => 'original', 
    :authorize_params => { 
     :force_login => 'true' 
    } 
    } 

    #provider3 
    config.omniauth :google_oauth2, ENV["GOOGLE_KEY"], ENV["GOOGLE_SECRET"]

一些变化，您应该给这个宝石一试。 https://github.com/AlexanderZaytsev/domp 快速且易于集成。我在30米左右有一个工作设置。
