Ruby on rails Can'；t通过考拉&；轨道

有人能够通过考拉向Facebook订阅页面提要吗？我能够订阅用户喜欢的内容、朋友、订阅源等，以及页面照片、登录。但我无法让Facebook订阅并在页面提要上发回更新。这是我在这本书中读到的 Rails控制台（回发url已更改）

更新。订阅（“页面”、“提要”http://domain.com/facebook_updates，FacebookUpdatesController:：验证\u令牌）
考拉：：Facebook：：APIError:OAutheException:（#100）“提要”是无效的字段名

好的……我想我又一次明白了。以下是我更正的内容：

正确设置您的Facebook应用程序，使其可访问Facebook页面。请参见教程

您必须订阅“用户”、“提要”才能访问页面的提要数据。例如：

更新。订阅（“用户”、“提要”、”http://domain.com/facebook_updates，FacebookUpdatesController:：验证\u令牌）

Omniauth必须具有适当的权限才能接收提要实时更新。特别是，我必须将“read_stream”添加到scope参数中。我将designe与Omniauth一起使用designe.rb文件中的一个示例：

config.omniauth:facebook、'APP\u ID'、'APP\u SECRET'、{:scope=>'发布\u流、电子邮件、脱机\u访问、用户\u位置、用户\u喜好、用户\u兴趣、阅读\u流、管理\u页面'， ：client_options=>{:ssl=>{:ca_file=>'/usr/lib/ssl/certs/ca certificates.crt'}

我真的希望这能帮助其他像我一样挣扎的人

updates.subscribe("page", "feed", "http://domain.com/facebook_updates", FacebookUpdatesController::VERIFY_TOKEN)
