我按照本指南尝试将Devise放入另一个可安装的宝石中: How To: Use devise inside a mountable engine
除了omniauth部分外,一切似乎都正常。我正试图让omniauth-google-oauth2工作。我发现it's a known issue in Devise,但除了没有提出的解决方案有效之外,我注意到该问题中提到的解决方案has already been implemented inside Devise。
这是我到目前为止所做的:
my_engine / my_engine.gemspec
s.add_dependency 'omniauth'
s.add_dependency 'devise'
s.add_dependency 'omniauth-google-oauth2'
my_engine / LIB / my_engine.rb
require 'omniauth-google-oauth2'
require 'devise'
my_engine /配置/初始化/ devise.rb
config.omniauth :google_oauth2, ENV['GOOGLE_OAUTH2_API_KEY'], ENV['GOOGLE_OAUTH2_SECRET'], scope: 'email, profile'
my_engine /配置/ routes.rb中
devise_for :users, controllers: {omniauth_callbacks: 'my_engine/omniauth_callbacks'}, class_name: "MyEngine::User", module: :devise
my_engine /应用/控制器/ my_engine / omniauth_callbacks_controller.rb
class MyEngine::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def all
auth = request.env["omniauth.auth"]
user = MyEngine::User.from_omniauth(request.env["omniauth.auth"])
user.update_attributes(name: auth.info.name)
if user.persisted?
flash.notice = 'Signed in!'
sign_in_and_redirect user
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_url
end
end
alias_method :google_oauth2, :all
end
当我点击“使用Google OAuth2登录”时,它会直接转到MyEngine::OmniauthCallbacksController#passthru
并输出“未找到。身份验证passthru”。我一直在挖掘源代码,但我无法弄清楚Devise如何通过提供程序方法而不是#passthru
。我在这里错过了什么吗?我正在运行rails 4.1,Ruby 2.0,设计3.2.4和omniauth-oauth2 1.2.0。

我也有这个问题。我工作的版本与您链接到的github问题页面上讨论的解决方案非常相似,但不完全相同(我已经调整了我在下面的代码中稍微做了些什么,因为我还有一个自定义{{1}在我的:path
中指定的。此外,我目前正在设计3.1.2但希望这与以下内容完全相似,为你工作。
在 my_engine / config / routes.rb :
devise_for
my_engine / config / initializers / devise.rb 中的:
devise_for :users, :class_name => 'MyEngine::User', :module => :devise, :controllers => { :omniauth_callbacks => "my_engine/omniauth_callbacks" }
devise_scope :user do
# Had to add routes for callbacks here because otherwise the routes get
# messed up -- prepending an extra "/my_engine" in one case.
providers = Regexp.union(Devise.omniauth_providers.map(&:to_s))
path_prefix = '/users/auth'
match "#{path_prefix}/:provider",
:constraints => { :provider => providers },
:to => "omniauth_callbacks#passthru",
:as => :user_omniauth_authorize,
:via => [:get, :post]
match "#{path_prefix}/:action/callback",
:constraints => { :action => providers },
:to => 'omniauth_callbacks',
:as => :user_omniauth_callback,
:via => [:get, :post]
end
其中一些可能是不必要的,但是我花了一些时间通过调试器逐步完成流程并且没有时间回去尝试使其更优雅/精益任何东西。

我找到了更好的解决方案。更新您的lib / MyEngine / engine.rb。 使用此解决方案,您不必添加设计范围部分(我的示例仅适用于facebook)
module MyEngine
require 'omniauth'
require 'omniauth-facebook'
class Engine < ::Rails::Engine
isolate_namespace SimpleUser
middleware.use OmniAuth::Builder do
provider :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET'], :scope => ENV['FACEBOOK_SCOPE']
end
end
