如何通过推送通知标头数据查找事件列表(在第 4 行中提到.)
How can I find event list by push notification headers data (mentioned in line 4.)
推荐答案
标头数据中没有更改的资源/事件列表.谷歌只是让你知道你的日历发生了一些变化.
There is no changed resource/event list in header data. Google just lets you know that something has changed in your calendar.
要在每次 Google Post 请求后获取更改的资源，您需要使用 syncToken 从 google 列出您的日历事件并保存新的事件，该事件将显示为 nextSyncToken回复.如果您在请求中提供 syncToken 参数，您将只能获得从 syncToken 到现在的更改.Google 将此过程称为 增量同步.
To get changed resources after every Google Post request, you need to list events of your calendar from google with syncToken and save the new one which will appear as nextSyncToken in response. If you provide syncToken parameter in your request, you will only get the changes from syncToken to now. Google calls this process incremental sync.

请从此处阅读 syncToken 和 nextSyncToken 参数:https://developers.google.com/google-apps/calendar/v3/reference/events/list
