实现最简单的队列通信
send端
# Author: Sooele 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
#_*_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
