Python 运行与RabbitMQ相关的sender.py和receiver.py文件时出错

运行发送方和接收方文件时出现错误堆栈

Traceback (most recent call last):
  File "C:/Users/A3245643/PycharmProjects/events/receive.py", line 7, in <module>

recieve.py充当消费者

# from send import channel


import pika, sys, os


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

channel.queue_declare(queue='iptbotQueue')


def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)

channel.basic_consume(queue='iptbotQueue',
                      auto_ack=True,
                      on_message_callback=callback)

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

我已经设置了rabbit mq，所以我应该用下图中的url替换localhost值吗

---

我想我需要为localhost值提供IP地址（例如：172.11.12.33）

或者只添加主机名而不添加“http”示例slacktestbot mq.omnitank.bestbuy.com

# from send import channel


import pika, sys, os


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

channel.queue_declare(queue='iptbotQueue')


def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)

channel.basic_consume(queue='iptbotQueue',
                      auto_ack=True,
                      on_message_callback=callback)

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