c# - Azure TimerTrigger 无法在 .NET 7 独立工作进程中工作

Question

我正在尝试触发 .NET 7 中的编排函数 TimerTrigger。以下是我创建的函数

    [Function(nameof(FunctionSampleTimer))]
    public async Task Run([TimerTrigger("*/5 * * * * *", RunOnStartup = false)] MyInfo myTimer, [DurableClient] DurableTaskClient client, FunctionContext context)
    {
        var instanceid = Guid.NewGuid().ToString();
        var logger = context.GetLogger("TimerFunction");
        logger.LogInformation($"Function Ran. Next timer schedule = {myTimer.ScheduleStatus.Next}");
    } 

上述函数仅在项目创建时第一次每 5 秒触发一次，并且不会再次触发并卡在“主机锁租约已获取...”行上。

控制台输出显示:

Answer 1

我在 .NET 7 独立 Azure 函数中观察了每一分钟和几分钟生成 GUID Id 的情况，它运行成功:

以下是我的测试用例:

<表类=“s-表”><标题>对于每个第一次运行下一次运行 <正文>2分钟是是1分钟是是60秒是是30秒是否5秒是否

---

每分钟:

每 2 分钟:

每 60 秒:

每 5 秒:

据我所知，CRON 表达式中最短的间隔至少需要 60 秒 - Hostinger - Cron Job Tutorial 的文章中也提到了这一点.
