Omniauth的自定义策略

Question

我需要为Rails中的应用实施自定义策略，软件版本：Rails 5.0.7.2红宝石2.3.2p217（2016-11-15修订版56796）[x86_64-linux]Bundler版本1.16.6

这些是我添加的文件：

# config/initializers/omniauth.rb
module OmniAuth
  module Strategies
    # tell OmniAuth to load our strategy
    autoload :Platform, 'lib/strategies/platform.rb'
  end
end

Rails.application.config.middleware.use OmniAuth::Builder do
  # pass the 2 parameters to the constructor
  provider :platform, "Client Id", "Client Secret",
      client_options: {
        site: "https://my.auth.provider",
        user_info_url: "/connect/userinfo"
      }

end

现在，在我的lib / strategies /目录中，创建了我的策略文件：

# lib/strategies/platform.rb
require 'omniauth-oauth2'

module OmniAuth
  module Strategies
    class Platform < OmniAuth::Strategies::OAuth2
      option :name, :platform

      option :client_options, {
        :site => "https://my.auth.provider",
        :authorize_url => "/connect/authorize",
        :user_info_url => "/connect/userinfo"
      }

      uid { raw_info["id"] }

      info do
        {
          :email => raw_info["email"]
          # and anything else you want to return to your API consumers
        }
      end

      def raw_info
        @raw_info ||= access_token.get('/connect/userinfo/me.json').parsed
      end

      def callback_url
        full_host + script_name + callback_path
      end
    end
  end
end

并且我在config / routes.rb中注册了回调URL：

#OAuth2 Generic
get "/auth/:provider/callback" => "sessions#create"

现在，我正在尝试配置的该应用程序已经为Google，Twitter和Facebook设计并启用了omniauth，但由于某种原因，我的URL从未得到注册。我想念什么？我该怎么办？我想有

user_platform_omniauth_authorize_path and
user_platform_omniauth_callback_path

Answer 1

class User < ApplicationRecord
  devise :omniauthable, omniauth_providers: %i[platform]
end
