OmniAuth拒绝回电

标签： ruby-on-rails omniauth

当我在Rails 3应用程序中使用OmniAuth启动登录过程时，如果我在提供商的页面上取消，我会收到一个类似于以下内容的URL：

http://example.com/auth/twitter/callback?denied=aUho....

我的应用程序抛出一个500，我可以看到它是OAuth :: Unauthorized：401 Unauthorized，没有触及任何控制器操作。

堆栈跟踪是我在计算机中重现的时间：

如果我继续登录（没有在Twitter的页面上点击取消），那么一切都按预期正常工作。对于Facebook来说，我可以很好地登录，但如果我按下“取消”＃39;在Facebook的页面上，我被重定向回来，我扔了500。

有没有办法更好地处理这个问题？我希望能够展示一个漂亮的页面。

当出现故障时，大多数时间取决于故障类型，OmniAuth会调用OmniAuth.config.on_failure，默认设置为OmniAuth::FailureEndpoint。默认情况下，它应该在开发模式下引发异常并以其他方式重定向：

def call
  raise_out! if ENV['RACK_ENV'].to_s == 'development'
  redirect_to_failure
end

根据the docs，默认端点为/auth/failure。

如果这不能按预期工作，那么即使在开发模式下，您也可以通过将其添加到初始化程序来强制重定向始终发生：

class SafeFailureEndpoint < OmniAuth::FailureEndpoint
  def call
    redirect_to_failure
  end
end

OmniAuth.config.on_failure = SafeFailureEndpoint

来自https://github.com/intridea/omniauth/issues/616

的更简洁的解决方案 
# Added to config/initializers/omniauth.rb
OmniAuth.config.on_failure = Proc.new { |env|
  OmniAuth::FailureEndpoint.new(env).redirect_to_failure
}

我有同样的问题，（facebook取消点击）

添加

后

# Added to config/initializers/omniauth.rb
OmniAuth.config.on_failure = Proc.new { |env|
  OmniAuth::FailureEndpoint.new(env).redirect_to_failure
}

将auth回调路由实现为

在config / routes.rb

中 
match '/auth/failure' => 'sessions#failure'

会话控制器看起来像

class SessionsController < ApplicationController
  def failure
    redirect_to #route that you want redirect
  end
end

我遇到了同样的问题，使用Pramod的解决方案我得到了一个“未知操作”错误，但是在我将回调路由更改为

之后工作了

配置/ routes.rb中

devise_scope :user do
  get '/users/auth/failure' => 'sessions#failure'
end

Rails 3.2.14
设计3.1.1
Omniauth 1.1.4

答案 3 :(得分：0)

对于那些使用omniauth_facebook和类似Users :: OmniauthCallbacksController的人使用：

配置/ routes.rb中

devise_scope :user do
  get '/omniauth/failure' => 'users/omniauth_callbacks#failure'
end

应用程序/控制器/用户/ omniauth_callbacks_controller.rb 

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    ...
  end
  def failure
    redirect_to root_path
  end
end

如果您正在使用FB弹出窗口

应用程序/控制器/用户/ omniauth_callbacks_controller.rb 

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    ...
  end
  def failure
    if request.env['HTTP_REFERER'] == "https://www.facebook.com/"
      render 'failure', :layout => false
    else
      redirect_to root_path
    end
  end
end
