有没有办法阅读已发布的google apps脚本的日志？
目前，我可以在调试模式下使用Logger.log()获取日志。
但是当我们在发布脚本时遇到某些问题时，就无法实现其原因。

这是我用于记录和错误检查的调试对象。它总是写入Logger，但也写入一个名为＆＃34; log＆＃34;在链接的电子表格中。我已经从我正在处理的脚本（Flubaroo）中复制了这个内容，因此可能会遗漏一些外部函数。

更新（2015年3月11日）：我已经转移到使用BetterLog和我的own wrapper library for BetterLog自动将函数名称添加到调试跟踪（MqTFuiXcPtS5rVUZ_jC9Z4tnfWGfgtIUb）。

不可能。根据它的执行方式，您最多可以访问上一次运行日志，它会在下一个脚本运行日志中丢失。 制作自己的记录器功能，例如在电子表格上执行appendRow。我做过一个甚至记录每个日志的完整堆栈跟踪，这比本机记录器更好。 这当然会让您记录罕见的事件，因为它会消耗更多的配额。 有关记录stacktrace等的示例代码，请参见此处（滚动到中间）： http://plusfortrello.blogspot.com/2013/08/spent-for-trello-google-apps.html
