pika - python rabbitMQ flush_output错误

Question

程序：

while(1):
    # query tasks from local file
    if task:
        publish(video_id)
    else:
        sleep(1)

长时间运行后，会报出以下错误，这是啥意思？

Traceback (most recent call last):
  File "publisher_dev.py", line 209, in <module>
    publish(video_id)
  File "publisher_dev.py", line 157, in publish
    delivery_mode=2,  # make message persistent

Answer 1

클라이언트와 서버 간의 연결 시간이 초과되었습니다. time.sleep() 대신에connection.sleep()을 사용해야 합니다
