FixDelayRetry 锁定函数

Question

   [FunctionName("FixedDelayRetryTest")]  
   [FixedDelayRetry(5, "00:01:00")]  
   public void Run(  
       [ServiceBusTrigger("Topic", "Subscription", Connection = "ServiceBusConnString")] string item,  
       ExecutionContext context,  
       ILogger log  
   )  
   {  
       log.LogInformation($"Function executed at: {DateTime.Now}");  
     
       throw new System.Exception("Error Happened!!");  
   }  

在测试 Azure 函数的机制（v3 - .NET Core 3.1）时，FixedDelayRetry

卡在像函数这样的场景中不会处理下一条消息，直到函数消耗所有剩余的重试并且该消息最终进入死信队列！

Note：此问题总结整理于:FixedDelayRetry locking up the Function

Answer 1

You are seeing this behavior because you are throwing exception in the code. Please throw the exception in the catch block so that you dont encounter the retries.

[FunctionName("FixedDelayRetryTest")]

[FixedDelayRetry(5, "00:01:00")]

public void Run(

[ServiceBusTrigger("Topic", "Subscription", Connection = "ServiceBusConnString")] string item,

ExecutionContext context,

ILogger log

)

{

try

{

log.LogInformation($"Function executed at: {DateTime.Now}");

}

catch

{

throw new System.Exception("Error Happened!!");

}

}
