python 发送和接收ActiveMQ

ActiveMQ是java开发的消息中间件服务。可以支持多种协议（AMQP,MQTT,OpenWire,Stomp），默认的是OpenWire。而python与ActiveMQ的通信使用的是Stomp协议。而如果你的服务没有开启则需要配置开启。

首先需要安装python的stomp库。命令如下：

pip install stomp.py

接着，就是上代码了具体如下：

# -*-coding:utf-8-*-
import stomp
import time
queue_name = '/queue/SampleQueue'
topic_name = '/topic/SampleTopic'
listener_name = 'SampleListener'
class SampleListener(object):
    def on_message(self, headers, message):
        print 'headers: %s' % headers
        print 'message: %s' % message
# 推送到队列queue
def send_to_queue(msg):
    conn = stomp.Connection10([('127.0.0.1',61613)])
    conn.start()
    conn.connect()
    conn.send(queue_name, msg)
    conn.disconnect()
#推送到主题
def send_to_topic(msg):
    conn = stomp.Connection10([('127.0.0.1',61613)])
    conn.start()
    conn.connect()
    conn.send(topic_name, msg)
    conn.disconnect()
##从队列接收消息
def receive_from_queue():
    conn = stomp.Connection10([('127.0.0.1',61613)])
    conn.set_listener(listener_name, SampleListener())
    conn.start()
    conn.connect()
    conn.subscribe(queue_name)
    time.sleep(1) # secs
    conn.disconnect()
##从主题接收消息
def receive_from_topic():
    conn = stomp.Connection10([('127.0.0.1',61613)])
    conn.set_listener(listener_name, SampleListener())
    conn.start()
    conn.connect()
    conn.subscribe(topic_name)
    while 1:
        send_to_topic('topic')
        time.sleep(3) # secs
    conn.disconnect()
