Azure Function QueueTrigger - 将新项目放回队列

Question

I have an Azure Function based on a QueueTrigger . This gets triggered when something appears on the queue, but after I processed this item, I then want to put new items back on the queue.

Is there a way to do this directly from within the Azure Function?

[Function("Batch")]
public async Task Run([QueueTrigger("batch", Connection = "DataQueue")] string data,
    FunctionContext context)
{
    var model = JsonConvert.DeserializeObject<MyObject>(data);

    // 1. process model
    // 2. Put items back on queue?
}

You can use output bindings as the following:

[StorageAccount("MyStorageConnectionAppSetting")]
public static class QueueFunctions
{
    [FunctionName("QueueOutput")]
    [return: Queue("myqueue-items")]
    public static string QueueOutput([HttpTrigger] dynamic input,  ILogger log)
    {
        log.LogInformation($"C# function processed: {input.Text}");
        return input.Text;
    }
}
