带有 2 个计时器触发器的单个 Azure Functions

Question

不确定这是否可以完成，因为我在网上发现了相互矛盾的答案。

我有一个 Azure 函数应用程序：

[Function("RetrieveMongoData")]
 public void Run([TimerTrigger("0 0 * * * *")] TimerInfo myTimer)
 { .....

  [Function("RetrieveMongoDataNL")]
  public void Run([TimerTrigger("0 5 * * * *")] TimerInfo myTimer)
  {....

每个函数都在自己的类中。当我在 VS 中按 F5 进行调试时，上面的第一个函数被命中，我可以调试该函数。在第二个函数中放置一个断点，它永远不会被击中。我可以像这样创建触发器还是有更好的方法？

我这样做是因为我的很多被调用的代码将在两个触发器之间共享。

Answer 1

• 当您在一个函数应用程序中本地创建两个计时器触发函数时，将为每个函数创建两个单独的 .cs 文件。
• 验证CRON表达式是否正确。例如，我在函数中使用了

  * * * * *

  和

  */2 * * * *

  表达式。
• 确保 Azurite 在本地调试时正在运行。您可以通过单击 Fn + F1 启动 Azurite，然后在 VS Code 中选择 Start Azurite。还要在本地设置文件中将 AzureWebJobsStorage 设置为 UseDevelopmentStorage=true。

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
  }
}

检索MongoData.cs：-

[Function("RetrieveMongoData")]
public void Run([TimerTrigger("* * * * *")] TimerInfo myTimer)
{
    _logger.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
            
    if (myTimer.ScheduleStatus is not null)
    {
        _logger.LogInformation($"Next timer schedule at: {myTimer.ScheduleStatus.Next}");
    }
}

检索MongoDataNL.cs：-

[Function("RetrieveMongoDataNL")]
public void Run([TimerTrigger("*/2 * * * *")] TimerInfo myTimer)
{
    _logger.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
            
    if (myTimer.ScheduleStatus is not null)
    {
        _logger.LogInformation($"Next timer schedule at: {myTimer.ScheduleStatus.Next}");
    }
}

两个功能均在本地成功触发。

然后，我将这些功能部署到应用程序服务计划功能应用程序中，并能够得到预期的响应。
