Google日历v3错误“所请求的最短修改时间过去太过分了。 [410]"

问题描述

我们使用Google Calendar v3 API返回自某时间点以来已更新的用户的活动列表。

在v2 API中在过去设定这个日期方面没有限制。

如果我们将UpdatedMin设置得太早（例如2个月），那么就会抛出错误

请求的最短修改时间过去太过分了[410]

如果我们将ShowDeleted设置为false，那么我们就不会收到错误信息。

我在这里找不到任何限制。有人知道这个限制的细节吗？不幸的是，当同步日历时，当同步没有运行一段时间的日历时（除了运行我们希望避免的完整列表之外），这是一个显示限制器。

  EventsResource.ListRequest lr = new EventsResource.ListRequest（service，c.uc.calendar）; 
 
 lr.UpdatedMin = c.primaryModTime.ToLocalTime（）; 
 lr.ShowDeleted = true; 
 Events el = lr.Execute（）; 
 if（el.Items.Count> 0）
 {
  

以下也讨论这个问题，但没有任何解决。

有一些解释：

它表示在410应该擦除存储并执行完全同步。

同时考虑按照上一段中的建议切换到同步令牌。

We are using the Google Calendar v3 API to return a list of events for a user that have been updated since a point in time.

In the v2 API there was no limitation on setting this date in the past.

If we set the UpdatedMin to a date too far back (like 2 months) then the error is thrown

"The requested minimum modification time lies too far in the past. [410]"

If we set ShowDeleted to false then we do not get the error.

I cannot find any reference to a limitation here. Does anybody know the details of this limit. Unfortunately when synchronising calendars this is a show stopper when synchronisation has not run for a period of time for a calendar (other than running a full list which we would prefer to avoid)

EventsResource.ListRequest lr = new EventsResource.ListRequest(service, c.uc.calendar);

lr.UpdatedMin = c.primaryModTime.ToLocalTime();
lr.ShowDeleted = true;
Events el = lr.Execute();
if (el.Items.Count > 0)
{

the following also discusses this issue but without any resoluton.

解决方案

There is some explanation at:

https://developers.google.com/google-apps/calendar/v3/sync

It says that on 410 you should wipe your storage and perform a full sync instead.

Also consider switching to sync tokens as recommended in the last paragraph.
