RabbitMQ发送消息＋python

接口使用两个queue监听信息，且有两个测试环境，所以需要向mq中发送测试数据：

python使用pika包：Pika is a RabbitMQ (AMQP-0-9-1) client library for Python.

可以参照： https://github.com/pika/pika

import pika
connection = pika.BlockingConnection()
channel = connection.channel()
channel.basic_publish(exchange=‘example‘,
                      routing_key=‘test‘,
                      body=‘Test Message‘)
connection.close()

将发送消息封装成一个函数：stream.py

具体代码如下：

import pikaimport jsonfrom config import env

def send_msg(msg_exchange, msg_key, msg, msg_type=None):    if str(env.__name__) == ‘Beta‘:        if msg_type is None:            connection = pika.BlockingConnection(pika.URLParameters(                ‘amqp://talaris:[email protected]:5672/talaris‘))        else:            connection = pika.BlockingConnection(pika.URLParameters(                ‘amqp://talaris:[email protected]:5672/clair‘))

elif str(env.__name__) == ‘Alpha‘:        if msg_type is None:            connection = pika.BlockingConnection(pika.URLParameters(               ‘amqp://talaris:[email protected]:5672/talaris‘))        else:            connection = pika.BlockingConnection(pika.URLParameters(                ‘amqp://talaris:[email protected]:5672/clair‘))

channel = connection.channel()

channel.basic_publish(exchange=msg_exchange,                          routing_key=msg_key,                          body=json.dumps(msg))

print(" [x] Sent %r:%r" % (msg_key, msg))    connection.close()

ps： 我用的是pika.URLParameters，也可以使用 pika.ConnectionParameters(host=‘localhost‘)，详细参考github
