如何根据环境设置Facebook身份验证密钥? [英] How to set facebook authentication keys depending on environment?
问题描述
我有一个Rails应用，该应用使用omniauth通过Facebook验证访问者身份.
I have a rails app which uses omniauth to authenticate visitors via facebook.
在Facebook中注册应用程序时，您必须注册一个回调网址，一旦他们完成身份验证过程，它们就会重定向到该网址.
When you register an app with facebook, you have to register a callback url which they will redirect to once they have completed their authentication process.
由于我的生产站点托管在与开发环境不同的服务器上，因此我需要在Facebook中注册2个不同的URL.为此，我注册了两个应用程序，一个是实时应用程序，另一个是开发版本.
Since my production site is hosted on a different server than my development environment, I need to register 2 different urls with Facebook. I've done this by registering two apps, a live one and a dev version.
当然，现在我有两个app_id和两个app_secrets，它们是我的Rails应用程序需要使用的.
Now of course I have two app_ids and two app_secrets which my Rails application needs to use.
如何设置OmniAuth在开发环境中使用一组密钥，而在生产环境中使用另一组密钥?
How do I set OmniAuth to use one set of keys in the development environment and another in production?
我试图像下面这样在/config/environments目录中设置密钥:
I've tried to set my keys in my /config/environments directory like so:
# development.rb
SampleApp::Application.configure do
config.omniauth_keys.facebook.app_id = "32423423"
config.omniauth_keys.facebook.api_key = "324234324234324"
config.omniauth_keys.facebook.app_secret = "242343424234324324234324"
end
# production.rb
SampleApp::Application.configure do
config.omniauth_keys.facebook.app_id = "7657566"
config.omniauth_keys.facebook.api_key = "7756765765756757"
config.omniauth_keys.facebook.app_secret = "65756767567567567757"
end
，然后在/config/initializers/omniauth.rb
and then in /config/initializers/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
keys = SampleApp::Application.config.omniauth_keys
# ==> OmniAuth Provider Credentials
# APP_ID SECRET_ID
provider :facebook, keys.facebook.app_id, keys.facebook.app_secret
end
但我知道
`method_missing': undefined method `omniauth_keys'
当我尝试启动开发服务器时，我在猜测是因为omniauth.rb是在/emvironments/*之前加载的?
when I try to start the development server, I'm guessing because omniauth.rb is loaded before /emvironments/* ?
我该如何设置?

推荐答案
在/config/initializers/omniauth.rb
In /config/initializers/omniauth.rb
if Rails.env.production?
# set the app parameter
elsif Rails.env.development?
# set the app parameter
else
# test env
# set the app parameter
end
注意:Rails.env.production?是Rails 3的方法.我认为对于2.x版本，您可能必须使用RAIL [ENV]或类似的东西.
Note: Rails.env.production? is a Rails 3 method. I think for 2.x versions you might have to use RAIL[ENV] or something like that.
