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localhost的程序运行正常。但是连接到远程队列的程序不起作用。创建连接时必须出错,因为我看不到日志消息'connection created'。
我已经验证我可以从我的机器访问remotehost,端口并且凭据是正确的。我可以访问
http://remote-host:15672/#/queues
我错过了任何明显的事情吗?
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。

需要正确指定虚拟主机。在我的情况下,我的队列属于虚拟主机。但我试图连接到' /'。指定虚拟主机(下面的产品)后,我就能成功连接。
发现此link很有帮助。
#!/usr/bin/env python
import pika
# this queue is the destination queue
credentials = pika.PlainCredentials('xxxx', 'xxxx')
parameters = pika.ConnectionParameters('remote-host', 5672, 'product', 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()

使用5672端口而不是15672! 它应该工作!
