无法通过Java中的事件ID提取Google日历事件异常 [英] Trouble fetching Google calendar event exceptions by event id in Java
问题描述
我一直在使用Java的Gdata API(v2)，并弄清楚了如何通过事件ID来获取事件.但是，我在获取重复出现的事件的异常时遇到了麻烦.
I've been working with the Gdata API for Java (v2), and have figured out how to fetch events by their id. However, I'm having trouble fetching exceptions to recurring events.
对于常规活动，我会这样获取它:
For a regular event, I would fetch it as such:
CalendarEventEntry event = getCalendarService().getEntry(new URL("https://www.google.com/calendar/feeds/"+googleCalId+"/private/full/"+eventId), CalendarEventEntry.class);
，正在查询的网址看起来像这样:
and the url being queried would look something like this:
https://www.google.com/calendar/feeds/772olgd23vedk7cmvmqgcke5jps%40group.calendar.google.com/private/full/6qlnf002ge3kh6fmp3i6skbuk
它可以毫无问题地获取！
And it fetches with no issue!
轻松自在.
但是，当我尝试使用相同的方法获取重复发生的事件的例外事件时，我遇到了问题.重复事件的网址为
However, when I try to fetch an event that is an exception to a recurring event using the same method, I run into problems. The url of the repeating event would be
https://www.google.com/calendar/feeds/772olgd23vedk7cmvmqgcke5jps%40group.calendar.google.com/private/full/6qlnf002ge3kh6fmp3i6skbuk_20120112
相同的网址，附加了_20120112.问题的性质:
Same url, with _20120112 appended. The nature of the problem:

任何人都知道为什么会发生这种情况，或者有更好的方法来解决此问题?
Anybody have any ideas why this is happening or better ways to go about this?
推荐答案
经过大量的测试和开发，我得出的结论是，您可以重复事件的方式获取异常，就像获取正常事件的方式一样，但要注意:无法取消.
Well after much testing and development, I've concluded that you can fetch exceptions to repeating events in the same way one fetches normal events, with one caveat: they can't be canceled.
男人真是头疼:-P
