我的一些连续运行的Web作业功能(随机)显示Timeout value of 00:30:00 exceeded by function '<myfunction>' (Id: '<id>'). Initiating cancellation
的消息。
在此消息之后,除非手动停止并启动azure Web作业,否则此功能将不会自行执行。
提前致谢。

我的一些连续运行的Web作业功能(随机)显示
Timeout value of 00:30:00 exceeded by function '<myfunction>' (Id: '<id>'). Initiating cancellation
的消息。
根据您的错误,我在FunctionExecutor.cs下找到了来自 Microsoft.Azure.WebJobs.Host 的相关代码,如下所示:
internal static void OnFunctionTimeout(System.Timers.Timer timer, FunctionDescriptor method, Guid instanceId, TimeSpan timeout, bool timeoutWhileDebugging,
TraceWriter trace, ILogger logger, CancellationTokenSource cancellationTokenSource, Func<bool> isDebuggerAttached)
{
timer.Stop();
bool shouldTimeout = timeoutWhileDebugging || !isDebuggerAttached();
string message = string.Format(CultureInfo.InvariantCulture,
"Timeout value of {0} exceeded by function '{1}' (Id: '{2}'). {3}",
timeout.ToString(), method.ShortName, instanceId,
shouldTimeout ? "Initiating cancellation." : "Function will not be cancelled while debugging.");
trace.Error(message, null, TraceSource.Execution);
logger?.LogError(message);
trace.Flush();
// Only cancel the token if not debugging
if (shouldTimeout)
{
// only cancel the token AFTER we've logged our error, since
// the Dashboard function output is also tied to this cancellation
// token and we don't want to dispose the logger prematurely.
cancellationTokenSource.Cancel();
}
}
我假设您为函数指定了TimeoutAttribute
,如下所示:
我建议您可以在函数中使用CancellationToken
参数,并且只要发生超时或主机关闭就会取消它,您可以按照以下方式正常退出函数:
