我正在开发一个使用 定时器触发器.
I am developing a triggered webjob that use TimerTrigger.
在webjob停止之前,我需要处理一些对象,但我不知道如何触发webjob stop".
Before the webjob stops, I need to dispose some objects but I don't know how to trigger the "webjob stop".
拥有 NoAutomaticTrigger 功能,我知道我可以使用 WebJobsShutdownWatcher 类在 webjob 停止但触发作业时处理我需要一些帮助...
Having a NoAutomaticTrigger function, I know that I can use the WebJobsShutdownWatcher class to handle when the webjob is stopping but with a triggered job I need some help...
我看了使用 Azure WebJobs SDK 1.1.0-alpha1 的可扩展触发器和绑定器.
创建一个使用 WebJobsShutdownWatcher 类在 webjob 停止之前触发动作的自定义触发器 (StopTrigger) 是个好主意吗?
Is it a good idea to create a custom trigger (StopTrigger) that used the WebJobsShutdownWatcher class to fire action before the webjob stops ?
推荐答案好的 答案就在问题中:
Ok The answer was in the question :
是的,我可以使用 WebJobsShutdownWatcher 类,因为它有一个 Register 函数,在取消令牌被取消时调用,换句话说,当 webjob 停止时.
Yes I can use the WebJobsShutdownWatcher class because it has a Register function that is called when the cancellation token is canceled, in other words when the webjob is stopping.
static void Main() { var cancellationToken = new WebJobsShutdownWatcher().Token; cancellationToken.Register(() => { Console.Out.WriteLine("Do whatever you want before the webjob is stopped..."); }); var host = new JobHost(); // The following code ensures that the WebJob will be running continuously host.RunAndBlock(); }编辑(基于马修评论):
如果您使用触发函数,您可以将 CancellationToken 参数添加到您的函数签名中.当主机自动关闭时,运行时将取消该令牌,从而允许您的函数接收通知.
If you use Triggered functions, you can add a CancellationToken parameter to your function signatures. The runtime will cancel that token when the host is shutting down automatically, allowing your function to receive the notification.
public static void QueueFunction( [QueueTrigger("QueueName")] string message, TextWriter log, CancellationToken cancellationToken) { ... if(cancellationToken.IsCancellationRequested) return; ... }更多推荐
