# You may ask why we declare the queue again ‒ we have already declared it in our previous code.

channel.basic_consume(#消费消息
callback,#如果收到消息，就调用CALLBACK函数来处理消息
queue='hello',#从哪个队列里收消息
#no_ack=True)#no acknowledgement 不确认 开启的话表示不确认消息是否接收 接没接收都不会给服务器端发消息 如果客户端没收到消息就忽略了
#关闭的话就要服务器就要确认消息是否接收，没有确认到接收消息就会一直保留消息,会自动转到另一个客户端，socket一断，rabbitMQ就将消息转给另一个客户端
#发送端生产者发送一条消息，被消费者接受者收到了，消费者接收端处理完之后自动给生产者发送端发一个确认，说消息处理完了，然后生产者发送端才会把消息从队列里删除，只要没收到确认就不会删除，如果生产者发送端没收到确认，就会把消息转给另一个消费者接收端
