Google 应用脚本 - 日历更新触发 4 次
Google App Script - Calendar Update Trigger Firing 4 Times
目标：当 Google 工作区 1 中的辅助日历事件更新（新建、编辑、删除）时，更新 Google 工作区 1 中的主日历以添加新的、编辑现有事件，或删除现有事件。
注意：Google 工作区 1 中的辅助日历是从 Google 工作区 2 共享的。因此，对事件的实际更新发生在 Google 工作区 2 中的辅助日历中，但是几乎立即反映为 Google 工作区 1.
中的辅助日历中的更新
结果：当 运行 手动时，这是按预期工作的。
问题：如果手动添加触发器 运行 秒后更新日历（不是基于时间的），触发器会触发脚本的四个并发执行。这会在 Google 工作区 1 中的辅助日历上复制日历事件四次。
已尝试解决：我设置了锁定服务。这确实可以防止日历事件重复。但是，这会导致四次执行中的三次失败。这导致向我发送 3 封电子邮件，每次脚本失败时发送一封电子邮件。
问题：如何让这个脚本只运行一次？我认为简单的答案是只放入一个 if/else 如果锁定，则终止脚本。我已经看过但找不到如何编码的示例。
请参阅下面的代码和屏幕截图。

您可以通过Lock.hasLock().
判断另一个脚本实例当前是否有锁
请注意，此方法并不总是避免冲突的最佳方法，因为无法判断锁是否是在更新 同一事件 或另一个事件恰好同时触发了一个触发器——正如the documentation所说，“触发器不会告诉你哪个事件改变了或者它是如何改变的."
您可能需要仔细研究Google Calendar events以确定如何同步日历。
或者，share the calendar 而不是尝试同步。

这可能是一个错误：
您描述的行为（EventUpdateTrigger -as well as EventOpenTrigger 多次触发）可能是一个错误，目前正在 Google 问题跟踪器上进行调查：
请考虑 starring the referenced issue 以跟踪它并帮助确定它的优先级。
解决方法：
As , use Lock.hasLock() 以避免连续触发器执行导致事件重复多次。
