在Python中利用 rabbitMQ實(shí)現(xiàn)生產(chǎn)與消費(fèi)者模式的方法

import pika
import sys
import time
 
# 遠(yuǎn)程rabbitmq服務(wù)的配置信息
username = 'admin' # 指定遠(yuǎn)程rabbitmq的用戶名密碼
pwd = 'admin'
ip_addr = '10.1.7.7'
port_num = 5672
 
# 消息隊(duì)列服務(wù)的連接和隊(duì)列的創(chuàng)建
credentials = pika.PlainCredentials(username, pwd)
connection = pika.BlockingConnection(pika.ConnectionParameters(ip_addr, port_num, '/', credentials))
channel = connection.channel()
# 創(chuàng)建一個(gè)名為balance的隊(duì)列，對(duì)queue進(jìn)行durable持久化設(shè)為T(mén)rue(持久化第一步)
channel.queue_declare(queue='balance', durable=True)
 
message_str = 'Hello World!'
for i in range(100000000):
  # n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange.
  channel.basic_publish(
    exchange='',
    routing_key='balance', # 寫(xiě)明將消息發(fā)送給隊(duì)列balance
    body=message_str, # 要發(fā)送的消息
    properties=pika.BasicProperties(delivery_mode=2, ) # 設(shè)置消息持久化(持久化第二步)，將要發(fā)送的消息的屬性標(biāo)記為2，表示該消息要持久化
  ) # 向消息隊(duì)列發(fā)送一條消息
  print(" [%s] Sent 'Hello World!'" % i)
  # time.sleep(0.2)
connection.close() # 關(guān)閉消息隊(duì)列服務(wù)的連接
