我使用 1.0.0 WebJobs SDK 连续运行 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)
{
...
}
我希望在成功运行函数后,从触发队列中删除消息。但是我让函数运行不止一次。
记录显示它在每个 nextVisibleTime 上运行,并且 dequeueCount 每次都在递增。
UPD:函数执行后似乎发生了错误。这是来自 webjob 仪表板的日志:
