应用程序引擎任务可以获取其运行次数吗？
我每小时在 Google App Engine 中运行数千个任务，其中大约 0.1% 即使在多次重试后也会失败。理想情况下，我希望他们停止尝试并退出。然而，由于应用程序引擎的设计，他们似乎只是一次又一次地尝试。我知道有一个退避时间，该时间会随着每次不成功的执行而增加，但我希望它们在 n 次重试后退出。
我可以以某种方式完成这个吗？任务可以获取其运行失败的次数吗？
I am running thousands of tasks per hour in Google App Engine and around .1% of them are failing even after multiple retries. Ideally, I want them to stop trying and exit. However, due to app engine's design they seem to be just trying again and again. I know there is a backoff time which increases with every unsuccessful execution, but I want them to exit after n retries altogether.
Can i accomplish this somehow? can a task get a count of the number of times it has unsuccessfully run?

是的，您可以通过阅读 X-AppEngine-TaskRetryCount HTTP 标头。
Yes, you can get a count of the number of times your task has been retried by reading the X-AppEngine-TaskRetryCount HTTP header.
