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的这篇文章odata.track-changes，该文章建议我将标头添加到我的请求中，我会收到一个deltaToken，我可以在以后的请求中使用它来仅获取自上次同步以来已更新或创建的那些事件。
我已经成功获取事件，但我没有得到 deltaToken 回来：/
这仅在 Outlook api 中支持吗？Graph 的响应有Preference-Applied: odata.track-changes，所以它承认我的标题。这是我的示例请求：
GET /v1.0/me/calendar/calendarView
?startDateTime=2016-09-01T00:00:00.0000000
&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
我的示例回复：

我编辑了我认为可能是轻度敏感的任何内容。最终，我的 Laravel 应用程序尝试同步 4 个月前开始的事件，并一直持续到未来。
如果有更有效/更好的方法来做到这一点，我愿意接受建议。如果重要的话，这些结果是由 Postman 生成的。对此的任何帮助或澄清表示赞赏。
