.net - Azure WebJob QueueTrigger 消息未从队列中删除

Question

我使用 1.0.0 WebJobs SDK 持续运行 WebJob。
这是配置代码。

public static void Main()
{
    var config = new JobHostConfiguration();
    config.Queues.MaxDequeueCount = 1;
    config.Queues.BatchSize = 1;

    var host = new JobHost(config);
    host.RunAndBlock();
}

这是我的工作职能签名。

public static void HuntVkusniyBlogRss([QueueTrigger("queue-rss")] string message,
    DateTimeOffset expirationTime,
    DateTimeOffset insertionTime,
    DateTimeOffset nextVisibleTime,
    string id,
    string popReceipt,
    int dequeueCount,
    string queueTrigger,
    CloudStorageAccount cloudStorageAccount,
    TextWriter log)
{
    ...
}

我希望成功运行函数后，消息将从触发队列中删除。但我让函数运行了不止一次。

日志记录显示它在每个 nextVisibleTime 上运行，并且 dequeueCount 每次都会递增。

UPD:看起来函数执行后发生了错误。以下是来自 webjob 仪表板的日志:

Answer 1

我遇到了这个问题，因为容器并不总是自动创建的。所以，我创建了:

azure-jobs-host-output
azure-webjobs-主机
