删除事件发生时从Microsoft Graph获取通知 [英] Get notification from Microsoft Graph when deleting event occurrence

问题描述

我已订阅事件(https://outlook.office.com/api/v2.0/me/events)推送通知.

I have subscribed to events (https://outlook.office.com/api/v2.0/me/events) push notification.

当我删除一个重复发生主事件的事件时，我收到具有主事件ID而不是特定发生事件ID的UPDATED通知.

When I delete one event of recurrence master event, I receive UPDATED notification with id of master event and not specific occurrence event id.

我怎么知道哪个事件被删除了而不与以前的所有重复事件进行比较?而且不会仅接收主ID事件.

How can I know which event was deleted without comparison with all previous recurrence events? And not receive only master id event.

推荐答案

删除"并出现时，从技术上讲，您并不是在删除实体.您实际上是在母版的重复模式中添加例外.这就是为什么您会收到有关主机已更新的通知，而不是有关事件已删除的通知的原因.

When you "delete" and occurrence, you're technically not deleting an entity. You're actual adding an exception to the master's recurrence pattern. This is why you're receiving a notification that the master was updated rather than a notification that an event was deleted.

您可以通过调用事件对象的集合(对于给定的主控).您可以通过查看type属性(可能的值为SingleInstance，Occurrence，Exception或SeriesMaster)来确定对象是发生还是异常.

You can see the list of event occurrences and exceptions by calling the /instances. This will return a collection of event objects for a given master. You can determine if an object is an occurrence or an exception by looking at the type property (possible values are SingleInstance, Occurrence, Exception, or SeriesMaster).
