Question

我确实遵循https://docs.microsoft.com/da-dk/azure/azure-functions/functions-host-json#functiontimeout中提到的准则，通过使用“ functionTimeout”更新主机文件，将应用服务计划上的功能应用程序主机的默认超时时间从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30m。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。

Answer 1

如果您按App Service计划运行，则应启用始终在线设置，以使功能应用程序正确运行。

即使启用了始终打开，单个功能的执行超时也由host.json项目文件中的functionTimeout设置控制。

有关更多详细信息，请参阅此article。

Answer 2

您始终可以在功能级别上使用属性 [Timeout（“ 1:00:00”）] 覆盖默认超时
