Question

我正在使用Microsoft Graph api尝试从Outlook同步日历事件。我正在查看有关Outlook API的this article，建议我将标头odata.track-changes添加到我的请求中，我会收到一个deltaToken，我可以在以后的请求中使用它来获取自上次同步以来已更新或创建的那些事件。

我成功获取了一些事件，但我没有收到deltaToken：/

这只在Outlook API中支持吗？图表的响应有Preference-Applied: odata.track-changes，因此它会确认我的标题。这是我的样本请求：

GET /v1.0/me/calendar/calendarView
    ?startDateTime=2016-09-01T00:00:00.0000000
    &amp;endDateTime=2099-01-01T00:00:00.0000000
    HTTP/1.1
Host: graph.microsoft.com
Authorization: Bearer XXX
Prefer: odata.track-changes
Prefer: odata.maxpagesize=3  //for testing
Cache-Control: no-cache

我的样本回复：

我编辑了任何我认为可能有点敏感的东西。最终，我的Laravel应用程序试图在4个月后开始同步事件，并永远进入未来。

如果有更有效/更好的方法，我可以接受建议。如果重要，这些结果是由Postman生成的。对此有任何帮助或明确表示赞赏。

我最终使用了odata filter，如此：

https://graph.microsoft.com/beta/me/calendar/calendarView?startDateTime=2016-05-01T00:00:00Z&endDateTime=2099-01-01T00:00:00Z&$filter=type eq 'singleInstance' and lastModifiedDateTime eq '2016-09-20T07:30:00+00:00'

这将获取在2016-05-01T00:00:00Z (May 1st, 2016, midnight, UTC和2099-01-01T00:00:00Z (January 1st, 2099, midnight, UTC)之间安排的所有日历活动，其中事件类型为singleInstance（不是定期事件），lastModifiedDateTime位于上次同步之后（在此示例中，2016-09-20T07:30:00+00:00）。

有一些陷阱：

显然，这不是网址编码。你需要这样做。
确保 lastModifiedDateTime示例中的+已正确编码为%2B，否则图谱API会将其视为空格并拒绝它。
如果您没有过滤掉重复出现的事件，那么从现在起到2099年，您将收到每个定期事件。这是获取calendarViews列表而不是events的性质。< / LI>
如果我能再次这样做，我可能会回去完成日历同步，Graph支持（我相信）。我只是不想同步整个日历，只是一个日期范围，但似乎这是一个注定要失败的努力。

但是，尽管缺乏重复发生的事件，但它确实有效。

<强>更新

我最终废弃了这个实现，主要是因为我在维护数据同步完整性，缺少重复性事件等方面遇到了持续的陷阱。相反，我实时提取日历事件，并维护缓存。只是一些建议，以防其他人在我的情况下结束。

我可以使用Microsoft Graph API同步日历活动吗？
