您如何在Rails 2.2上实现OmniAuth? [英] How do you implement OmniAuth on Rails 2.2?

问题描述

我正在尝试使用Omniauth为现有的Rails 2.2应用程序实现Facebook和Twitter身份验证.到目前为止，我还无法找到有关如何在Rails 2.2中执行此操作的任何建议-因此出现了这个问题.我有两个问题要问-

I am trying to implement Facebook and Twitter authentication using Omniauth for an existing Rails 2.2 application. So far I have been unable to find any advise on how to do this in Rails 2.2 - hence this question. I have two questions to ask -

1. 我了解从2.3开始引入了对Rails的Rack支持，并且我认为OmniAuth需要Rack.那么甚至可以在Rails 2.2网站上使用OmniAuth，为什么?

1. I understand Rack support for Rails was introduced from 2.3 and I believe Rack is needed for OmniAuth. So is it even possible to use OmniAuth on a Rails 2.2 website and why ?

如果可以实现OmniAuth-您将如何实现?

If it is possible to implement OmniAuth - how would you do it ?

推荐答案

您不能使用默认的config.gem"omniauth" ...使其正常工作，我做了以下工作:

You can't use the default config.gem "omniauth" ... to get it working i did the following:

1. 手动安装omniauth

sudo gem install omniauth

2.在config/environment.rb文件中的 Rails初始化程序之前进行此操作.

2.Require it before the Rails Initializer in the config/environment.rb file.

require 'omniauth'
Rails::Initializer.run do |config| ....

3.在development.rb文件中，我添加了以下配置

3.In development.rb file i've added the following configuration

config.middleware.use OmniAuth::Builder do
 provider :facebook, "XXx", "YYYY", :scope => % (email user_birthday publish_stream offline_access)
end

在此处添加任意数量的提供程序....其他所有功能都应按预期运行.

Add as many providers as you want here .... everything else should work as expected.
