我正在使用fb_graph rails gem将消息发布到用户的Facebook提要中。
我已请求以下权限：
:scope => 'email, publish_actions, offline_access, publish_stream'
我可以发布到用户的提要。但我无法摧毁它。
当我在 Rails 控制台中执行以下命令时，您可以看到错误：
me = FbGraph::User.me( user.access_token )
@facebookpost = me.feed!( :message => "sample feed message", :description => 'sample message')
post = me.feed.find(@facebookpost.identifier).first
post.destroy # this generates the following error

我是否错过了任何权限？我该怎么做才能解决此问题？
您可以使用以下方法删除帖子
FbGraph::Post.new(fb_post_id).destroy(access_token: "access_token")
虽然不是最好的API...
v2.4 要求您将fb_post_id与客户端 ID 组合在一起。
FbGraph2::Post.new("#{client_id}_#{fb_post_id}", access_token: "access_token").destroy
