Azure WebJobs:VisibilityTimeout&;MaxDequeuCount不能一起工作
我使用的是Azure WebJobs SDK 2.0,当我指定VisibilityTimeout然后指定MaxDequeuCount时,消息在失败3次时不会从队列中删除,而是仅复制到中毒队列。您可以看到DequeueCount大于MaxDequeuCount,并且消息仍在队列中Azure WebJobs:VisibilityTimeout&;MaxDequeuCount不能一起工作,azure,azure-webjobs,Azure,Azure Webjobs,我使用的是Azure WebJobs SDK 2.0,当我指定VisibilityTimeout然后指定MaxDequeuCount时,消息在失败3次时不会从队列中删除,而是仅复制到中毒队列。您可以看到DequeueCount大于MaxDequeuCount,并且消息仍在队列中 class Program { // Please set the following connection strings in app.config for this WebJob to ru

函数正在抛出异常以模拟错误条件
public class Functions

public static void ProcessQueueMessage([QueueTrigger("queue")] string message, TextWriter log)

log.WriteLine(message);
throw new Exception("There was an error processing the message");

尝试三次后,消息将移动到毒药队列,这是预期的,但大约10分钟后,移动到毒药队列的消息将再次出现在队列中。
在队列中,您可以看到Dequeue count大于MaxDequeuCount,并且消息仍然没有从队列中删除

{
// Please set the following connection strings in app.config for this WebJob to run:
// AzureWebJobsDashboard and AzureWebJobsStorage
static void Main()
{
var config = new JobHostConfiguration();

在毒药队列中,您可以看到M1消息被处理了两次
当消息失败3次时,它不会从队列中删除,而只是复制到队列中
据我所知,目前我们无法将Storage SDK 8.x与WebJobs SDK一起使用,其他人也报告了类似的问题
