Rails，Devise＆Omniauth - 設置問題

Question

我想（再次）使用Rails 4，devise和omniauth設置身份驗證。

我試圖按照這篇文章的例子：Rails 4, Devise, Omniauth (with multiple providers)

我已經安裝了這些寶石：

gem 'devise' 
gem 'omniauth-google-oauth2' 
gem 'omniauth-facebook' 
gem 'omniauth-twitter' 
gem 'omniauth-linkedin-oauth2' 
gem 'oauth2' 

我有一個用戶模型，以及模型認證。

我：

User.rb：

has_many :authentications 

def disapprove 
    self.approved = false 
    end 

    def approve 
    self.approved = true 
    end 

社交= { Facebook的：「Facebook的， google_oauth2： '谷歌'， LinkedIn： 'LinkedIn' }

def self.from_omniauth(auth, current_user) 
    authentication = Authentication.where(:provider => auth.provider, 
            :uid => auth.uid.to_s, 
            :token => auth.credentials.token, 
            :secret => auth.credentials.secret).first_or_initialize 
    authentication.profile_page = auth.info.urls.first.last unless authentication.persisted? 
    if authentication.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 
    authentication.user = user 
    authentication.save 
    end 
    authentication.user 
end 

def fetch_details(auth) 
    self.first_name = auth.info.first_name 
    self.last_name = auth.info.last_name 
    self.email = auth.info.email 
    self.image = URI.parse(auth.info.image) 
end 

Authentication.rb

belongs_to :user 

的routes.rb

devise_for :users, 
      :controllers => { 
:registrations => "users/registrations", 


      :omniauth_callbacks => 'users/omniauth_callbacks', 
      } 

用戶/ registrations_controller

class Users::RegistrationsController < Devise::RegistrationsController 
    #before_filter :check_permissions , :only => [ :new, :create, :cancel ] 
    #skip_before_filter :require_no_authentication 

    def check_permissions 
    authorize! :create, resource 
    end 

    def index 
    if params[:approved] == "false" 
     @users = User.find_all_by_approved(false) 
    else 
     @users = User.all 
    end 
    end 

    def create 
     @user = User.new(user_params) #(params[:user]) 

     respond_to do |format| 
      if resource.save 
      # Tell the UserMailer to send a welcome email after save 
      # {@user.send_admin_mail 
      # @user.send_user_welcome_mail} 

      format.html { redirect_to(profile_path(@user.profile))} 
      #, notice: 'We have received your registration. We will be in touch shortly.') } 
      #format.json { render json: root_path, status: :created, location: @user } 
      else 
      #format.html { redirect_to(root_path, alert: 'Sorry! There was a problem with your registration. Please contact us to sort it out.') } 
      format.html { render action: 'new' } 
      format.json { render json: @user.errors, status: :unprocessable_entity } 
      end 
     end 
     end 

     private 
     def user_params 
      params.require(:user).permit(:first_name, :last_name, :email, :password) 
     end 



     # protected 
     # def after_sign_up_path_for(resource) 
     #  'subscribers/new' 
     # end 
end 

用戶/ Omniauth_callbacks控制器

類用戶:: OmniauthCallbacksController <設計:: OmniauthCallbacksController

# try again following https://stackoverflow.com/questions/21249749/rails-4-devise-omniauth-with-multiple-providers 

    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 profile_path(@user.profile) 
     else 
     redirect_to root_path 
     end 
    else 
     session['devise.user_attributes'] = user.attributes 
     redirect_to root_path 
    end 
    end 

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

的色器件/新註冊的觀點說：

我有一個名爲profile.rb另一種模式。

profile belongs_to user 

問題：

1. 這一切都不工作。當我點擊每個社交媒體登錄鏈接時，頁面就會跳轉到通過電子郵件形式註冊。

Heroku的記錄錯誤消息指出：

(facebook) Authentication failure! invalid_credentials: OAuth2::Error, : 
2015-11-03T07:05:48.237549+00:00 app[web.1]: {"error":{"message":"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request","type":"OAuthException","code":100,"fbtrace_id":"HD3mnzmSTEw"}} 

當我與電子郵件和密碼完成註冊通過電子郵件形式，用戶名被識別（在導航欄說你好，但是當我進入軌道控制檯，用戶沒有列出。

此外，當我點擊用戶名，我得到它說，配置文件不存在的錯誤。Heroku的日誌說：

(Couldn't find Profile with 'id'=3) 

有沒有讓社交媒體註冊工作，以創建一個新用戶需要另一步？

我的一次新的嘗試：

我已經改變了上述所有的，並試圖再次，在Railscasts視頻的方法如下。

我現在使用用戶模型和身份驗證模型。

在user.rb，我有：

has_many :authentications, :dependent => :delete_all 

def apply_omniauth(omniauth) 
     authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'], :token => auth['credentials']['token']) 

end 

authentication.rb

belongs_to :user 

def self.from_omniauth(auth) 
    where(auth.slice(:provider, :uid)).first_or_create do | user | 
     authentication.provider = auth.provider 
     authentication.uid = auth.uid 
     authentication.user.first_name = auth.first_name 
     authentication.user.last_name = auth.last_name 
     authentication.user.image = auth.info.image 

    end 
    end 

Authentications_controller：

class AuthenticationsController < ApplicationController 
    before_action :set_authentication, only: [:destroy] 

    def index 
    @authentications = current_user.authentications if current_user 
    end 


    def create 
    omniauth = request.env["omniauth.auth"] 
    authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid']) 
    if authentication 
     sign_in_and_redirect_user(:user, authentication.user.profile) 

    elsif current_user 
     current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid']) 
     redirect_to user.profile_url 
    else 
     user = User.new 
     user.omniauth(omniauth) 
     if user.save! 
     sign_in_and_redirect_user(:user, user.profile) 
     else 
     session[:omniauth] = omniauth.except('extra') 
     redirect_to new_user_registration_url 
     end 
    end 
    end 

    def destroy 
    @authentication.destroy 
    respond_to do |format| 
     format.html { redirect_to authentications_url } 
     format.json { head :no_content } 
    end 
    end 

    private 
    # Use callbacks to share common setup or constraints between actions. 
    def set_authentication 
     @authentication = current_user.authentications.find(params[:id]) 
    end 
end 

在routes.rb中，我有：

devise_for :users, 
      :controllers => { 
       :registrations => "users/registrations", 
      } 
patch '/auth/:provider/callback' => 'authentications#create' 

Omniauth.rb

需要 'omniauth Facebook的' 需要 'omniauth，谷歌-的oauth2'

OmniAuth.config.logger = Rails.logger

Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :facebook, ENV['FACEBOOK_ID'], ENV['FACEBOOK_KEY'], 
    :scope => 'public_profile', info_fields: 'id,first_name,last_name,link,email', 
    :display => 'popup', 
    :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}} 

後來，當我嘗試這，我得到這個錯誤：

(facebook) Authentication failure! invalid_credentials: OAuth2::Error, : 
2015-11-05T06:4839+00:00 app[web.1]: {"error":{"message":"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request","type":"OAuthException","code":100,"fbtrace_id":"CrvXN22Z"}} 

我找到錯誤消息奇的下一個部分，因爲它是指通話後退控制器，我不再使用（整個事情被註釋掉，沒有路線）。

Authentication failure! invalid_credentials: OAuth2::Error, :

進一步企圖

我一直在試圖建立現在omniauth超過1.5年設計。這是我最近的嘗試（在sitepoint.com/rails-authentication-oauth-2-0-omniauth上的Sitepoint教程之後）。我之前嘗試過使用本教程，但沒有取得任何成功，所以我做了一些調整，嘗試將其應用於有關此主題的其他教程的某些方面。

我現在有：

user.rb

has_many :authentications, :dependent => :delete_all 

def apply_omniauth(omniauth) 
     authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'], :token => auth['credentials']['token']) 

    end 

認證。RB

belongs_to :user 
    def self.from_omniauth(auth) 
    where(auth.slice(:provider, :uid)).first_or_create do | user | 
     authentication.provider = auth.provider 
     authentication.uid = auth.uid 
     authentication.user.first_name = auth.first_name 
     authentication.user.last_name = auth.last_name 
     authentication.user.image = auth.info.image 

    end 
    end 

認證控制器

class AuthenticationsController < Devise::OmniauthCallbacksController 
     before_action :set_authentication, only: [:destroy] 

     def index 
     @authentications = current_user.authentications if current_user 
     end 


     def create 
     omniauth = request.env["omniauth.auth"] 
     authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid']) 
     if authentication 
      sign_in_and_redirect_user(:user, authentication.user.profile) 

     elsif current_user 
      current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid']) 
      redirect_to user.profile_url 
     else 
      user = User.new 
      user.omniauth(omniauth) 
      if user.save! 
      sign_in_and_redirect_user(:user, user.profile) 
      else 
      session[:omniauth] = omniauth.except('extra') 
      redirect_to new_user_registration_url 
      end 
     end 
     end 

     def destroy 
     @authentication.destroy 
     respond_to do |format| 
      format.html { redirect_to authentications_url } 
      format.json { head :no_content } 
     end 
     end 

     private 
     # Use callbacks to share common setup or constraints between actions. 
     def set_authentication 
      @authentication = current_user.authentications.find(params[:id]) 
     end 
    end 

註冊控制器

    #before_filter :check_permissions , :only => [ :new, :create, :cancel ] 
    #skip_before_filter :require_no_authentication

    def check_permissions 
    authorize! :create, resource 
    end 

    def index 
    if params[:approved] == "false" 
     @users = User.find_all_by_approved(false) 
    else 
     @users = User.all

    end 

    def create

路線

我可以檢查這些路線：

rake routes | grep auth 
         user_omniauth_authorize GET|POST /users/auth/:provider(.:format)                 authentications#passthru {:provider=>/facebook|linkedin|twitter|google_oauth2/} 
         user_omniauth_callback GET|POST /users/auth/:action/callback(.:format)               authentications#:action 
               GET  /auth/:provider/callback(.:format)                authentications#create 

新登記的觀點

<%- if devise_mapping.omniauthable? %>

        <%= link_to "Join with Twitter", user_omniauth_authorize_path(:twitter) %> 
        </div>

部分我真的不知道這條道路是從哪裏來的。不知道它爲什麼被命名。

新的會話視圖部分

<%- if devise_mapping.omniauthable? %>

當前出錯：

AbstractController::ActionNotFound at /users/auth/twitter/callback 

The action 'twitter' could not be found for AuthenticationsController
