python basic_ack 生成者怎么回调 python生成api文档 # sphinx模块生成api文档的方式是对 /source/conf.py 文件的编写 sphinx官方文档:https://zh-sphinx-doc.readthedocs.io/en/latest/intro.html sphinx需要安装:sudo pip3 install sphinx sphinx的

hello world模式中指定了auto_ack=True,表示consumer接收到message之后自动发送确认标识,告诉RabbitMQ可以从队列中移除该条message了。工作队列模式下,使用了默认值,即需要手动确认ch.basic_ack(delivery_tag=method.delivery_tag)。 hello world模式中只有一个consumer去处理queue中的message,工作队列模式中可以有多个consum...
