我有一个应用程序，我正在尝试使用twitter，linkedin和facebook添加身份验证以及使用设计我的自定义身份验证
我的 Gemfile 如下
gem 'devise'
gem 'omniauth'
gem 'omniauth-facebook'
gem 'omniauth-linkedin'
gem 'omniauth-twitter'
gem 'oauth2'
gem 'figaro'
我正在使用设计3.2.4
我有一个 user.rb 模型，如下所示
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, :twitter, :linkedin]
TEMP_EMAIL_PREFIX = 'change@me'
TEMP_EMAIL_REGEX = /\Achange@me/
validates_format_of :email, :without => TEMP_EMAIL_REGEX, on: :update
def self.find_for_oauth(auth, signed_in_resource = nil)
# Get the identity and user if they exist
identity = Identity.find_for_oauth(auth)
# If a signed_in_resource is provided it always overrides the existing user
# to prevent the identity being locked with accidentally created accounts.
# Note that this may leave zombie accounts (with no associated identity) which
# can be cleaned up at a later date.
user = signed_in_resource ? signed_in_resource : identity.user
# Create the user if needed
if user.nil?
# Get the existing user by email if the provider gives us a verified email.
# If no verified email was provided we assign a temporary email and ask the
# user to verify it on the next step via UsersController.finish_signup
email_is_verified = auth.info.email && (auth.info.verified || auth.info.verified_email)
email = auth.info.email if email_is_verified
user = User.where(:email => email).first if email
# Create the user if it's a new registration
if user.nil?
user = User.new(
username: auth.extra.raw_info.name,
#username: auth.info.nickname || auth.uid,
email: email ? email : "#{TEMP_EMAIL_PREFIX}-#{auth.uid}-#{auth.provider}.com",
password: Devise.friendly_token[0,20]
)
user.skip_confirmation!
user.save!
end
end
# Associate the identity with the user if needed
if identity.user != user
identity.user = user
identity.save!
end
user
end
def email_verified?
self.email && self.email !~ TEMP_EMAIL_REGEX
end
end
我的 identity.rb 如下
class Identity < ActiveRecord::Base
belongs_to :user
validates_presence_of :uid, :provider
validates_uniqueness_of :uid, :scope => :provider
def self.find_for_oauth(auth)
identity = find_by(provider: auth.provider, uid: auth.uid)
identity = create(uid: auth.uid, provider: auth.provider) if identity.nil?
identity
end
end
users_controller.rb
class UsersController < ApplicationController
before_action :set_user, :finish_signup
before_filter :ensure_signup_complete, only: [:new, :create, :update, :destroy]
def finish_signup
if request.patch? && params[:user] #&& params[:user][:email]
if current_user.update(user_params)
current_user.skip_reconfirmation!
sign_in(current_user, :bypass => true)
redirect_to current_user, notice: 'Your profile was successfully updated.'
else
@show_errors = true
end
end
end
private
def set_user
@user = User.find(params[:id])
end
def user_params
accessible = [ :username, :email ] # extend with your own params
accessible << [ :password, :password_confirmation ] unless params[:user][:password].blank?
params.require(:user).permit(accessible)
end
end
omniauth_callbacks_controller.rb
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def self.provides_callback_for(provider)
class_eval %Q{
def #{provider}
@user = User.find_for_oauth(env["omniauth.auth"], current_user)
if @user.persisted?
sign_in_and_redirect @user, event: :authentication
set_flash_message(:notice, :success, kind: "#{provider}".capitalize) if is_navigational_format?
else
session["devise.#{provider}_data"] = env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
}
end
[:twitter, :facebook, :linked_in].each do |provider|
provides_callback_for provider
end
def after_sign_in_path_for(resource)
if resource.email_verified?
super resource
else
finish_signup_path(resource)
end
end
end
/config/routes.rb
devise_for :users, :controllers => { omniauth_callbacks: 'omniauth_callbacks' }
match '/profile/:id/finish_signup' => 'users#finish_signup', via: [:get, :patch], :as => :finish_signup
get 'home/index'
root to: "home#index"
配置/初始化/ devise.rb
Devise.setup do |config|
config.omniauth :facebook, ENV["FACEBOOK_KEY"], ENV["FACEBOOK_SECRET"]
config.omniauth :twitter, ENV["TWITTER_KEY"], ENV["TWITTER_SECRET"]
config.omniauth :linked_in, ENV["LINKEDIN_KEY"], ENV["LINKEDIN_SECRET"]
...
end
application_controller.rb
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
def ensure_signup_complete
# Ensure we don't go into an infinite loop
return if action_name == 'finish_signup'
# Redirect to the 'finish_signup' page if the user
# email hasn't been verified yet
if current_user && !current_user.email_verified?
redirect_to finish_signup_path(current_user)
end
end
end
我尝试将 routes.rb 更改为
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
从我的应用程序的根目录
mkdir app / controllers / users mv app / controllers / omniauth_callbacks_controller.rb app / controllers / users
然后我从
更改了omniauth_callbacks_controller.rbclass OmniauthCallbacksController < Devise::OmniauthCallbacksController
到
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
在我的routes.rb中，我改变了
devise_for :users, :controllers => { omniauth_callbacks: 'omniauth_callbacks' }
devise_for :users, :controllers => { omniauth_callbacks: 'users/omniauth_callbacks' }
然后我重新启动了我的服务器，当我尝试使用linkedin登录时，我收到了错误，
The action 'linkedin' could not be found for Users::OmniauthCallbacksController
我错过了什么？

答案 0 :(得分：4)
您必须指定正确的提供商名称。在您的代码中，我可以看到您使用的名称linked_in不正确，您必须将所有这些名称更改为linkedin
