RABBITMQ：如何在Python生产商和消费者之间发送Python Integer数据类型？

Question

我知道如何将字符串，字典和JSON传递给RMQ，但是如何将简单的整数传递到RMQ？

我的send.py文件看起来像这样

import sys
import json

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='task_queue', durable=True)

message = {'id': 7, 'name': 'Akshat'}
channel.basic_publish(exchange='',
                      routing_key='task_queue',
                      body=json.dumps(message),
                      properties=pika.BasicProperties(
                         delivery_mode = 2, # make message persistent
                      ))
print(" [x] Sent %r" % message)
connection.close()

，recect.py看起来像这样

import time
import json

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='task_queue', durable=True)
print(' [*] Waiting for messages. To exit press CTRL+C')

def callback(ch, method, properties, body):
    print(" [x] Received %r" % json.loads(body))
    #print(body['id'])
    print(" [x] Done")
    ch.basic_ack(delivery_tag = method.delivery_tag)

channel.basic_qos(prefetch_count=1)
channel.basic_consume(callback,
                      queue='task_queue')

channel.start_consuming()
