C# 获取新闻源引发异常

我正在尝试使用MVC中的以下代码从facebook获取新闻提要

public ActionResult Index()
{
   JsonObject Data = new JsonObject();
   var fb = new FacebookClient("my_accesstoken");
   dynamic parameters = new ExpandoObject();
   parameters.q = "SELECT created_time, updated_time, message, attachment, likes, share_count FROM stream WHERE filter_key in ( SELECT filter_key FROM stream_filter WHERE uid = me() ) AND created_time <= now() AND is_hidden=0"; 

   dynamic result = fb.Get("fql", parameters);

   retuen View();
}

---

任何帮助都会得到通知。

我不是此API的专家，但根据异常结束时的输出，它看起来像是应用程序权限错误。你读过这篇文章吗
