tp6.0 rabbitmq死信队列

rabbitMq交换机，队列情况，先手动创建

复制代码

1. 创建普通交换机exchange，普通队列order_queue_expire，队列设置属性：
消息过期时间：60000毫秒，过期绑定dead_exchange交换机，routing_key:dead_queue

2. 创建deal_exchange交换机，dead_queue,通过路由key:dead_queue 绑定

tp6.0为例

    public function producer()
    {
        // 设置队列的TTL和死信交换机
        $deadExchangeName = 'dead_exchange';
        $deadQueueName = 'dead_queue';
        $messageTtl = 1 * 60 * 1000; // 1分钟

        $connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
        $channel = $connection->channel();

        //死信交换机和路由
        $tale = new AMQPTable();
        $tale->set('x-dead-letter-exchange', $deadExchangeName);
        $tale->set('x-dead-letter-routing-key', $deadQueueName);
        $tale->set('x-message-ttl', $messageTtl);

        // 声明普通队列
        $queueName = 'order_queue_expire';

        $channel->queue_declare($queueName, false, true, false, false, false,$tale);

        // 将普通队列绑定到普通交换机
        $channel->queue_bind($queueName, 'exchange', $queueName);

        $channel->exchange_declare($deadExchangeName, 'direct', false, true, false);
        $channel->queue_declare($deadQueueName, false, true, false, false);
        $channel->queue_bind($deadQueueName, $deadExchangeName, $deadQueueName);

        for($i = 1000; $i < 1010; $i++) {
            $payload = json_encode(['order_id' => $i]);
            $msg = new AMQPMessage($payload, array('delivery_mode' => 2));
            sleep(1);
            $channel->basic_publish($msg, '', $queueName);
        }

        // 确保在脚本结束时关闭通道和连接
        register_shutdown_function(function () use ($channel, $connection) {
            $channel->close();
            $connection->close();
        });

        dd('ok');
    }
