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 pika
import json
from 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:talaris@vpcb-talaris-mq-1.vm.elenet.me:5672/talaris‘))
        else:
            connection = pika.BlockingConnection(pika.URLParameters(
                ‘amqp://talaris:talaris@vpcb-talaris-mq-1.vm.elenet.me:5672/clair‘))

    elif str(env.__name__) == ‘Alpha‘:
        if msg_type is None:
            connection = pika.BlockingConnection(pika.URLParameters(
               ‘amqp://talaris:talaris@vpca-talaris-mq-1.vm.elenet.me:5672/talaris‘))
        else:
            connection = pika.BlockingConnection(pika.URLParameters(
                ‘amqp://talaris:talaris@vpca-talaris-mq-1.vm.elenet.me: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
