我将我的问题分享到*@developer.gserviceaccount.com，
和我添加了 http://www.google.com/calendar/feeds/ 请求范围。

I solved my problem sharing the calendar to the *@developer.gserviceaccount.com, and I added http://www.google.com/calendar/feeds/ to scope of the request.

我正在使用的日历也来自Google Apps用户，所以我也添加了我的帐户* .apps.googleusercontent.com - > http://www.google.com/calendar/feeds/ 从Google管理API客户端访问应用程序控制面板。

The calendar that I'm using is also from a google apps user so I add also my account *.apps.googleusercontent.com -> http://www.google.com/calendar/feeds/ to Manage API client access from google apps control panel.
