如何知道已删除哪些重复发生的事件？
我的应用已订阅称为ConferenceRoom的office365日历。因此，当事件被创建/修改/删除时，office365服务器将向我的应用程序发送通知，告知这三个事件发生了。
在日历中，我为每个星期一（通过浏览器）创建定期活动站立会议。在此之后，我的应用会收到ChangeType: Created的通知，这是该通知事件的重复部分：
Recurrence:
{ Pattern:
{ Type: 'Weekly',
Interval: 1,
Month: 0,
DayOfMonth: 0,
DaysOfWeek: [Object],
FirstDayOfWeek: 'Sunday',
Index: 'First' },
Range:
{ Type: 'NoEnd',
StartDate: '2016-09-12',
EndDate: '0001-01-01',
RecurrenceTimeZone: 'FLE Standard Time',
NumberOfOccurrences: 0 } },
该事件的整个数据（id来自通知）：

这很好。当我在日历中删除该事件的一次出现时出现问题。我的应用会收到ChangeType: Updated的通知，该通知的正文与创建活动时的内容非常相似。没有关于该活动被取消的日期的信息。
eventId来自ChangeType: Updated通知时的事件数据：

这是图像，以清除我在日历中的确切做法：
您能告诉我如何知道哪个事件被删除了吗？
这似乎是死路一条，所以任何帮助都会受到赞赏。
仅供参考：周期性事件只有一个eventId并删除一次重复出现的事件并不会发送ChangeType: DELETED的通知
1 个答案:
答案 0 :(得分：1)
不幸的是，API目前不会让您知道哪个事件已被删除。当您删除单个事件时，它会触发SeriesMaster上的更新。当此更新进入时，您将必须计算何时应该发生所有会议，然后获取所有发生的事件。迭代事件后，您可以推断出已从先前计算中删除的事件。由于您的会议将永远每周重复一次，因此您需要限制您请求发生的时间范围。
如果使用Python，我强烈推荐使用方便的rrule类附带的dateutil包：https://dateutil.readthedocs.io/en/stable/rrule.html
