Question

我刚刚部署了appengine应用程序，当我休息时，调用触发队列，我得到UnknownQueueError。看来异常是在下面的源代码行中抛出的。关于导致问题的原因的任何想法。我在本地进行测试，效果非常好。

 q.add(task)

异常

源代码

 task = Blueprint('tasks.stock.prices.dispatch', __name__)
 @task.route('/tasks/stock/prices/dispatch')
 def run():
  q = taskqueue.Queue('push-queue')
  from_date = request.args.get('from')
  to_date = request.args.get('to')

  with open(os.path.join(os.path.dirname(__file__), 
            "../resources/dow_30.csv")) as csvfile:

    reader = csv.DictReader(csvfile)
    for row in reader:
        ticker = row['TICKER']
        stock_code = row['StockCode']

        task = taskqueue.Task(
            url='/tasks/stock/prices/shard',
            target='internal-api',
            headers={'Content-Type' : 'application/json'},
            payload=json.dumps({'ticker': ticker, 'stock_code': stock_code, 'from' : from_date, 'to' : to_date}))

        logging.info("StockCode :=" + stock_code)

        q.add(task)

return "OK"

当我部署应用程序时，我忘了部署queue.yaml。一旦我做了以下（由@DanCornilescu提供），它解决了这个问题。

gcould app deploy <path_to_your_queue.yaml>

Google App Engine错误未知任务队列
