使用fb_graph gem共享facebook中的东西

我试图在使用fb_graph(2.6.0)创业板创建内容时共享facebook，
在尝试时，我会发现以下错误：
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

从您的问题来看，您似乎正在使用应用程序访问令牌来访问用户信息。重新进入
FbGraph::InvalidRequest: OAuthException :: An active access token must be used to query information about the current user.然而，您应该使用用户的访问令牌获取配置文件信息或在您的墙上张贴。
如果您正尝试使用Facebook进行全方位登录，下面是一个很好的入门教程：http://blog.yangtheman.com/2012/02/09/facebook-connect-with-rails-omniauth-devise/
当使用图表时，您应该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(墙帖)
这需要一个访问令牌，您应该在为该用户验证应用程序时保存该令牌。
你可以做
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:这需要扩展权限，您可以在作用域属性中指定这些权限。
Rails.application.config.middleware.use OmniAuth::Builder do
# The following is for facebook
provider :facebook, [APP ID], [SECRET KEY], {:scope => '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.
