实现最简单的队列通信

 

send端

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#!/usr/bin/env python import pika   connection = pika.BlockingConnection(pika.ConnectionParameters(                'localhost')) channel = connection.channel()   #声明queue channel.queue_declare(queue='hello')   #n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange. channel.basic_publish(exchange='',                       routing_key='hello',                       body='Hello World!') print(" [x] Sent 'Hello World!'") connection.close()

receive端

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

#_*_coding:utf-8_*_ __author__ = 'Alex Li' import pika   connection = pika.BlockingConnection(pika.ConnectionParameters(                'localhost')) channel = connection.channel()     #You may ask why we declare the queue again ‒ we have already declared it in our previous code. # We could avoid that if we were sure that the queue already exists. For example if send.py program #was run before. But we're not yet sure which program to run first. In such cases it's a good # practice to repeat declaring the queue in both programs. channel.queue_declare(queue='hello')   def callback(ch, method, properties, body):     print(" [x] Received %r" % body)   channel.basic_consume(callback,                       queue='hello',                       no_ack=True)   print(' [*] Waiting for messages. To exit press CTRL+C') channel.start_consuming()

 

远程连接rabbitmq server的话，需要配置权限 噢 

首先在rabbitmq server上创建一个用户

1	sudo rabbitmqctl  add_user alex alex3714

同时还要配置权限，允许从外面访问

1	sudo rabbitmqctl set_permissions -p / alex ".*" ".*" ".*"

set_permissions [-p vhost] {user} {conf} {write} {read}

vhost

The name of the virtual host to which to grant the user access, defaulting to /.

user

The name of the user to grant access to the specified virtual host.

conf

A regular expression matching resource names for which the user is granted configure permissions.

write

A regular expression matching resource names for which the user is granted write permissions.

read

A regular expression matching resource names for which the user is granted read permissions.

 

 

 

　　

客户端连接的时候需要配置认证参数

1 2 3 4 5 6

credentials = pika.PlainCredentials('alex', 'alex3714')     connection = pika.BlockingConnection(pika.ConnectionParameters(     '10.211.55.5',5672,'/',credentials)) channel = connection.channel()
