Python RabbitMQ sender.py 远程队列

Question

我正在尝试向远程计算机中的 rabbit mq 队列发送消息。我正在关注 this教程。

连接到本地主机的程序工作正常。但是连接到远程队列的程序不起作用。错误一定出在创建连接时，因为我看不到日志消息“已创建连接”。

我已经验证我可以从我的机器访问远程主机、端口并且凭据是正确的。我可以访问

http://remote-host:15672/#/queues

我是否漏掉了任何明显的东西？

本地

#!/usr/bin/env python
import pika

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

channel.basic_publish(exchange='', routing_key='hello', body='Hello World!')
print " [x] Sent 'Hello World!'"
connection.close()

远程

#!/usr/bin/env python
import pika

# this queue is the destination queue
credentials = pika.PlainCredentials('xxxx', 'xxxx')
parameters = pika.ConnectionParameters('remote-host', 15672, '/', credentials)
connection = pika.BlockingConnection(parameters)
print " connection created"

channel = connection.channel()
channel.queue_declare(queue='hello')

channel.basic_publish(exchange='helloEx', routing_key='', body='Hello World!')
print " [x] Sent 'Hello World!'"
connection.close()

更新这是我在尝试连接时遇到的错误。

Answer 1

使用 5672 端口而不是 15672!它应该有效!
