发送消息是消息队列中最常见的操作之一。在 Pika 中,发送消息通常涉及以下几个步骤:声明队列、声明交换器、绑定队列到交换器以及最终发送消息。这里有一个简单的示例: # 声明队列channel.queue_declare(queue='hello')# 声明交换器channel.exchange_declare(exchange='logs', exchange_type='fanout')# 绑定队列到交换...
比如某个队列 'rpc_queue' 是以前由其他python脚本创建的持久化队列,在rabbitmq中一直存在着。在某次写脚本时,也申明了一个同名的队列,但不是持久化的,就会报错。如果直接删除再创建,当然可以,像这样: channel.queue_delete(queue='rpc_queue') channel.queue_declare(queue='rpc_queue') 但实际上,创建队列时...
channel.queue_declare(queue=QUEUE_NAME,arguments={'x-max-priority':MAX_PRIORITY},durable=True) 同时在添加消息的时候需要指定 BasicProperties 对象的 delivery_mode 为 2,实现如下: properties=pika.BasicProperties(priority=int(priority),delivery_mode=2) ...
