发送JSON数据

通过调用rabbitmq.send_json(channel, user, queue=result)能够更简单的实现发送JSON数据。

生产者

import json
import rabbitmq# 建立连接
connection = rabbitmq.get_connection()# 创建管道
channel = connection.channel()# 创建队列
queue_name = "user_manager"
result = channel.queue_declare(queue=queue_name)# 向队列中写入数据
data = [{"id": 1, "name": "张三", "age": 23},{"id": 2, "name": "李四", "age": 24},{"id": 3, "name": "王五", "age": 35},
]
for user in data:rabbitmq.send_json(channel, user, queue=result)# 关闭连接
connection.close()

消费者

import json
import rabbitmq# 创建连接
connection = rabbitmq.get_connection()# 创建管道
channel = connection.channel()# 创建队列
queue_name = "user_manager"
channel.queue_declare(queue=queue_name, durable=False)def callback(ch, method, properties, body):# 解析队列中的每一条数据ch.basic_ack(delivery_tag=method.delivery_tag)data = body.decode("utf8")print(json.loads(data))# 告诉rabbitmq，用callback来接收消息
channel.basic_consume(queue_name, callback)# 开始接收信息，并进入阻塞状态，队列里有信息才会调用callback进行处理
try:channel.start_consuming()
finally:connection.close()
