【问题描述】：
我到处寻找，我遵循了 Ryan Bates 的传奇 360 Facebook 身份验证，但我仍然无法弄清楚为什么会得到这个：
The parameter app_id is required.
我不知道如何设置这些：ENV['FACEBOOK_APP_ID'] 和 ENV['FACEBOOK_SECRET']
设置这些的最简单方法是什么，以便当我点击服务时，它成功地从应该读取的任何内容中读取这些变量？我尝试将我从 Facebook 获得的值粘贴到 config.ru，但似乎没有从这里读取这些值（应用程序 ID 和应用程序密码），我仍然遇到同样的错误。
我不知道我错过了什么。
这是我目前所拥有的：
omniauth.rb:
OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET']
end
config.ru:
# This file is used by Rack-based servers to start the application.
require ::File.expand_path('../config/environment', __FILE__)
use Rack::Session::Cookie, :secret => '<my secret is here>'
use OmniAuth::Builder do
provider :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET'], :scope => 'email,read_stream'
end
run Rails.application
application.html.erb:

// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.

// These three cases are handled in the callback function.
