Python 生产者-消费者模式代码示例

消费者代码

#consumer.py
import pika
credentials = pika.PlainCredentials('guest', 'guest')
conn_params = pika.ConnectionParameters('localhost', credentials=credentials)

conn_broker = pika.BlockingConnection(conn_params)
channel = conn_broker.channel()

channel.exchange_declare(exchange='hello-exchange',
                         exchange_type='direct')

channel.queue_declare(queue='hello-queue')
channel.queue_bind(queue='hello-queue',
                   exchange='hello-exchange',
                   routing_key='hola')

def msg_consumer(channel, method, header, body):
  channel.basic_ack(delivery_tag=method.delivery_tag)
  if body == 'quit':
    channel.basic_cancel(consumer_tag='hello-consumer')
    channel.stop_consuming()
  else:
    print(body)
  return

channel.basic_consume(msg_consumer, queue='hello-queue', consumer_tag='hello-consumer')
channel.start_consuming()

生产者代码

#producer.py
import pika, sys

credentials = pika.PlainCredentials('guest', 'guest')
conn_params = pika.ConnectionParameters('localhost', credentials=credentials)

conn_broker = pika.BlockingConnection(conn_params)

channel = conn_broker.channel()

channel.exchange_declare(exchange="hello-exchange", exchange_type="direct")

msg = sys.argv[1]
msg_props = pika.BasicProperties()
msg_props.content_type = "text/plain"

channel.basic_publish(body=msg,
                      exchange="hello-exchange",
                      properties=msg_props,
                      routing_key='hola')

用例

第一步: 打开终端，执行 python3 consumer.py
第二步: 新开一个终端，执行 python3 producer.py message
可以在终端上看到相应的输出
