应用服务计划的Azure功能应用超时

Question

我确实遵循https://docs.microsoft.com/da-dk/azure/azure-functions/functions-host-json#functiontimeout中提到的指南，通过使用“functionTimeout”更新主机文件，将应用服务计划上的功能应用主机的默认超时从30分钟增加到2小时：“02:00:00”

在检查功能应用程序的事件查看器日志时，我可以看到超时限制仍然是30米。添加错误消息以供参考，

感谢您在覆盖自定义超时值方面的帮助。

如果您运行App Service计划，则应启用“始终开启”设置，以便您的功能应用程序正常运行。

即使启用了Always On，各个函数的执行超时也由functionTimeout项目文件中的host.json设置控制。
