Question

我正在尝试在使用fb_graph（2.6.0）gem创建内容时分享facebook，

我在尝试时遇到以下错误：

app = FbGraph::Application.new(APP_ID, :secret => APP_SECRET)
app.get_access_token
user = FbGraph::User.me(access_token).fetch

在开发控制台中

从您的问题看来，您似乎正在使用应用程序访问令牌来访问用户信息。

中的重新开始

FbGraph::InvalidRequest: OAuthException :: An active access token must be used to query information about the current user.

您应该使用用户的访问令牌来获取个人资料信息或在墙上发帖。

如果您尝试使用Facebook进行omniauth登录，这里有一个很好的入门教程http://blog.yangtheman.com/2012/02/09/facebook-connect-with-rails-omniauth-devise/

使用fb_graph时您应该拥有用户的访问令牌来执行任何进一步的操作，例如更新状态（墙贴）

这需要一个访问令牌，在为该用户验证应用时，您应该保存该访问令牌。

您可以

me = FbGraph::User.me(ACCESS_TOKEN)
me.feed!(
  :message => 'Updating via FbGraph',
  :picture => 'https://graph.facebook.com/matake/picture',
  :link => 'https://github.com/nov/fb_graph',
  :name => 'FbGraph',
  :description => 'A Ruby wrapper for Facebook Graph API'
)

注意：这需要您可以在范围属性

中指定的扩展权限

Rails.application.config.middleware.use OmniAuth::Builder do
  # The following is for facebook
  provider :facebook, [APP ID], [SECRET KEY], {:scope =&gt; 'email, read_stream, read_friendlists, friends_likes, friends_status, offline_access'}

  # If you want to also configure for additional login services, they would be configured here.
end

使用fb_graph gem在facebook中分享内容
