使用Python向RabbitMQ发送JSON数据只需要一个send_json方法

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()
