无法通过Koala & Rails订阅Facebook页面源

Question

有谁能通过Koala订阅网页源到Facebook呢？我可以订阅用户的喜好，朋友，提要等和网页照片，检查。但我无法让Facebook订阅并在Page上发布更新。下面是我在Rails控制台中运行的内容(修改了回发url )

updates.subscribe("page", "feed", "http://domain.com/facebook_updates", FacebookUpdatesController::VERIFY_TOKEN)
Koala::Facebook::APIError: OAuthException: (#100) "feed" is an invalid field name
    from /opt/ruby/lib/ruby/gems/1.9.1/gems/koala-1.2.1/lib/koala/graph_api.rb:217:in `block in graph_call'
    from /opt/ruby/lib/ruby/gems/1.9.1/gems/koala-1.2.1/lib/koala.rb:69:in `api'
    from /opt/ruby/lib/ruby/gems/1.9.1/gems/koala-1.2.1/lib/koala/graph_api.rb:215:in `graph_call'
    from /opt/ruby/lib/ruby/gems/1.9.1/gems/koala-1.2.1/lib/koala/realtime_updates.rb:62:in `subscribe'
    from (irb):66
    from /opt/ruby/lib/ruby/gems/1.9.1/gems/railties-3.1.0/lib/rails/commands/console.rb:45:in `start'

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

Ok...once，我想我又想通了。以下是我更正的内容：

1. 正确地设置您的Facebook应用程序，使其可供Facebook页面访问。参见教程http://www.hyperarts.com/blog/tutorial-add-an-iframe-application-to-your-facebook-fan-page-fall-2012/
2. You必须订阅“用户”、“提要”才能访问页面的提要数据。示例：

FacebookUpdatesController::VERIFY_TOKEN)

• Omniauth (“updates.subscribe”、" Feed“、"http://domain.com/facebook_updates"”、“http://domain.com/facebook_updates"”)必须具有接收Feed实时更新的适当权限。特别是，我必须将'read_stream‘添加到范围参数中。下面是devise.rb文件中的一个示例：

'/usr/lib/ssl/certs/ca-certificates.crt'}}} :facebook，'APP_ID'，‘APP_ config.omniauth’，{:scope => 'publish_stream，email，offline_access，user_location，user_likes，user_interests，read_stream，manage_pages'，:client_options => {:ssl => {:ca_file => =>

我希望这能帮助像我这样挣扎的人。
