rabbitMQ简单使用

#send.py
import pika
import sys

# 创建连接
connection = pika.BlockingConnection(pika.ConnectionParameters("localhost"))
# 创建channel
channel = connection.channel()
message = " ".join(sys.argv[1:]) or "hello world"
# 创建队列，并持久化存储
channel.queue_declare(queue="hello", durable=True)

channel.basic_publish(exchange='', routing_key="hello", body="message",
                      properties=pika.BasicProperties(delivery_mode=2))
connection.close()

#receive.py
import pika
import time

# 创建连接
connection = pika.BlockingConnection(pika.ConnectionParameters("localhost"))
# 创建channel
channel = connection.channel()
# 创建队列
channel.queue_declare(queue="hello", durable=True)


# 回调函数
def callback(ch, method, properties, body):
    print("[x] Received %r" % (body,))
    print(type(body))
    time.sleep(5)
    print("[x] Done")
    ch.basic_ack(delivery_tag=method.delivery_tag)


# 公平调度，让每个消费者执行时间相近
channel.basic_qos(prefetch_count=1)

channel.basic_consume(callback, queue="hello")
# 阻塞，等待接收
channel.start_consuming()
