php 使用AMQP扩展调用RabbitMq

 先试用Docker安装 RabbitMq

docker run -d --hostname my-rabbit --name rabbit -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password -p 15672:15672 -p 5672:5672 rabbitmq:management

    'vhost'=>'/'

$e_name = 'business'; //交换机名

//创建连接和channel
$conn = new AMQPConnection($conn_args);
