Python 操作rabbitmq中的confirm模式的错误

今天使用rabbitmq的confirm模式，书上介绍的是pika版本是0.9.6，但是我用的是别的版本，发现这样的错误

Traceback (most recent call last):
  File "hello_world_producer1.py", line 27, in <module>
    channel.confirm_delivery(confirm_handler)
TypeError: confirm_delivery() takes exactly 1 argument (2 given)

看官网后发现错了，应该改成下面的样式：

#!/usr/bin/env python #coding:utf-8 import pika,sys

from pika import spec credentials=pika.PlainCredentials('guest','guest')

conn_params=pika.ConnectionParameters('localhost',credentials=credentials) conn_broker=pika.BlockingConnection(conn_params) channel=conn_broker.channel()

channel.confirm_delivery()

#channel.confirm_delivery()

msg=sys.argv[1]

msg_props=pika.BasicProperties()

msg_props.content_type="text/plain" msg_ids=[]

if channel.basic_publish(body=msg,       exchange="hello-exchange",       properties=msg_props,       routing_key='hola'):

　　  print 'Confirm receive!'

else:  

　　print 'Message lost'

#msg_ids.append(len(msg_ids)+1)

channel.close()
