使用twython获取Direct Messages时“禁止”

Question

twitter = twython.Twython(oauth_token        = oauth_token,
                          oauth_token_secret = oauth_secret,
                          app_key            = oauth_consumer_key,
                          app_secret         = oauth_consumer_secret)
twitter.getDirectMessages()

TwythonError: 'Forbidden: The request is understood, but it has been refused. An accompanying error message will explain why. This code is used when requests are being denied due to update limits. -- An error occurred processing your request.'

我正在使用dev.twitter.com上“我的应用程序”页面上“详细信息”选项卡下显示的令牌，机密和密钥。我有点担心twython将其称为app_key，而twitter则将其称为consumer_key。也许我有困惑/倒退。

其他电话，例如twitter.getFriendsIDs（）成功。
