facebook - 无法在Facebook上添加/发布订阅以进行实时更新

我正在尝试通过Graph API Explorer添加/发布real time updates订阅。这是我要求的POST网址

https://graph.facebook.com/v2.2/ {APP_ID} /订阅/对象=用户安培;字段=朋友＆安培; verify_token = thisisaverifystring＆安培;的access_token = my_app_token＆安培; callback_url = http://mydomain/auth/facebook/callback/

但我收到了错误回复：

{ “错误”：{ “message”：“（＃2200）回调验证失败：”， “type”：“OAuthException”， “代码”：2200 } }

此外，我在路由中两次定义了相同的回调URL，以处理GET和POST请求。我上面提到的API请求正在点击我的回调网址，但我在服务器日志中也遇到错误

在2015-02-12 19:24:12 +0530开始GET“/auth/facebook/callback/?hub.mode=subscribe&hub.challenge=246450618&hub.verify_token=thisisaverifystring”for 66.220.158.118 我，[2015-02-12T19：24：12.530395＃18960] INFO - omniauth：（facebook）回调阶段已启动。 E，[2015-02-12T19：24：12.530916＃18960]错误 - omniauth：（facebook）身份验证失败！ no_authorization_code：OmniAuth :: Strategies :: Facebook :: NoAuthorizationCodeError，必须传递code（通过网址或fbsr_XXX已签名的请求Cookie）

我假设验证令牌有问题，但我不知道如何获得此令牌。
