pika异常连接关闭本地主机python

Question

以下是错误。它在1天前工作正常。但当我试图再次运行它时，它会给我以下错误。

Traceback (most recent call last):
File "C:/nor-devops/projects/nor_7sm_denaliml/denali/back_testing_agent_python_consumer.py", line 22, in <module>

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost')) 
File "C:\Anaconda\lib\site-packages\pika\adapters\blocking_connection.py", line 339, in __init__
 self._process_io_for_connection_setup()

File "C:\Anaconda\lib\site-packages\pika\adapters\blocking_connection.py", line 395, in _flush_output
raise exceptions.ConnectionClosed()
pika.exceptions.ConnectionClosed

代码如下：

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='init_filtering')

channel.basic_consume(callback,
                      queue='init_filtering',
                      no_ack=True)

print(' [*] Waiting for messages. To exit press CTRL+C')

channel.start_consuming()
