　　生成者：

#声明交换器

passive=False, #校验是否存在
durable=False, #是否持久化
auto_delete=False,#最后一个订阅后是否删除

　　消费者：

#声明交换器

,durable=True,auto_delete=False)
#声明队列
channel.queue_declare(queue="hello-queue")
#通过键hola 将队列和交换器绑定
channel.queue_bind(queue="hello-queue",exchange="hello-exchange",routing_key="hola")
#用于处理传入消息的函数
def msg_consumer(channel,method,header,body):
#消息确认
