如何在兔队列上使用同步消息？

import pika

# 建立与兔队列服务器的连接
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()

# 声明一个消息队列
channel.queue_declare(queue='sync_queue')

# 发送消息
channel.basic_publish(exchange='', routing_key='sync_queue', body='Hello, RabbitMQ!')

# 接收消息
method_frame, header_frame, body = channel.basic_get(queue='sync_queue', auto_ack=True)

if method_frame:
    # 处理消息
    print("Received message:", body)
    # 确认消息接收
    channel.basic_ack(delivery_tag=method_frame.delivery_tag)
else:
    print("No message available")

# 关闭连接
connection.close()
