rabbitmq中關於exchange模式type報錯

channel.exchange_declare(exchange='logs',
 type='fanout')

報錯：

Traceback (most recent call last):
  File "D:/fanout_server.py", line 12, in <module>
    type='fanout')
TypeError: exchange_declare() got an unexpected keyword argument 'type'

 

原因這里的type參數必須指定為exchange_type才行

channel.exchange_declare(exchange='logs',
 exchange_type='fanout')

改完之后運行正常，但奇怪的是有的人用type指定就沒問題，搞不懂
