当我在 Rails 3 应用程序中使用 OmniAuth 启动登录过程时，如果我在提供程序的页面上取消，我会被发送回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，我可以看到它是一个 OAuth::Unauthorized: 401 Unauthorized，而没有触及我的任何控制器操作。

当我在我的计算机中复制它时，堆栈跟踪是：

如果我继续登录（没有在 Twitter 页面上单击取消），那么一切都按预期正常工作。Facebook 也一样，我可以正常登录，但如果我在 Facebook 页面上按“取消”，我会被重定向回来并抛出 500。

有没有办法更好地处理这个问题？我希望能够显示一个不错的页面。

当出现故障时，大多数情况下取决于故障的类型，OmniAuth 将调用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，否则重定向：

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

根据文档，默认端点是/auth/failure.

如果这对您来说没有按预期工作，那么您可以通过将其添加到您的初始化程序来强制重定向始终发生，即使在开发模式下也是如此：

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
}

将身份验证回调路由实现为

在 config/routes.rb

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 的解决方案时，我遇到了“未知操作”错误，但在我将回调路由更改为

配置/路由.rb

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

Rails 3.2.14
设计 3.1.1
Omniauth 1.1.4

对于那些使用 omniauth_facebook 和类似 Users::OmniauthCallbacksController 的用户，请使用：

配置/路由.rb

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

如果您使用的是 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

:javascript
  window.close();
