python 发送和接收ActiveMQ消息

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() if __name__=='__main__': # send_to_queue('len 123') # receive_from_queue() receive_from_topic()

但是上述只是发送文本类型的消息,除此之外,ActiveMQ还支持MapMessage、ObjectMessage、BytesMessage、和StreamMessage等多个消息类型。
