带有队列和System.Threading.Timer的Azure WebJob

问题描述

我正在使用Azure WebJob成功地从服务总线队列中获取消息.但是我想使用同一WebJob每5秒运行一些方法.

I'm using Azure WebJob to get messages from a service bus queue with success.But i wanted to use this same WebJob to run some methods every 5 seconds.

我尝试了以下方法，并且在本地运行良好，但是当我发布时，它只能运行一次.天蓝色日志没有错误.

I've tried the following approach, and locally it run fine, but when i publish it only runs once.No errors on azure logs.

我在做什么错了?

感谢您的帮助.

   static void Main()
    {
        try
        {

    var testTimer = new System.Threading.Timer(e => TestMethod(), null, TimeSpan.FromSeconds(0), TimeSpan.FromSeconds(5));

            SetupJobHost();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }
    }

     private static void TestMethod()
    {
        Console.WriteLine("Test");
    }

推荐答案

我建议采用其他方法，并使用 TimerTrigger .您可以使用一个简单的chron表达式，该表达式将使您的方法按设定的时间表执行.如果走这条路，请确保在调用之前将WebJob部署为触发的作业(不连续！)，并在调用之前先调用 JobHostConfiguration 的 UseTimers()方法 JobHost 的 RunAndBlock 方法.与滚动自己的计时器服务相比，这是一种更轻松，更干净的方法.

I recommend taking a different approach and using a TimerTrigger. You can use a simple chron expression that will cause your method to be executed on a set schedule. If you go this route, make sure that you deploy your WebJob as a triggered job (not continuous!) and that you call the JobHostConfiguration's UseTimers() method before calling the JobHost's RunAndBlock method. This is a much easier and cleaner approach than rolling your own timer service.
