RabbitMq之生产者与消费者设置不同报错

相关环境：PHP7.4 + RabbitMQ 3.3.5 + Laravel8

生产者代码：

public function sendBasicMsg()    {
        try {
            $connection = new AMQPStreamConnection('127.0.0.1', 5672, 'guest', 'guest');
            $channel = $connection->channel();

            $queue = 'record-queue'; //队列名称
            //queue_declare第三个参数设置true代表开启队列持久化
            $channel->queue_declare($queue, false, true, false, false);

            $data = [
                'name' => 'YIF'
            ];
            //DELIVERY_MODE_PERSISTENT设置消息持久化
            $msg = new AMQPMessage(json_encode($data), ['delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT]);
            $channel->basic_publish($msg, '', $queue);

            echo " [x] Sent 'success'\n";

            $channel->close();
            $connection->close();
        } catch (\Exception $e) {
            Log::error("生产者发送消息异常：", [
                'method' => __METHOD__,
                'respone' => $e->getMessage() ?? ""
            ]);
        }
    }

生产者开启了队列，消息的持久化。

通过生产者生产了几条消息，来看看消费者代码：

public function consume($consumeName)
    {
        try {
            $connection = new AMQPStreamConnection('127.0.0.1', 5672, 'guest', 'guest');
            $channel = $connection->channel();
			
	    $queue = 'record-queue'; //队列名称
            //没有开启队列持久化
            $channel->queue_declare($queue, false, false, false, false);

            $callback = function ($msg) use ($consumeName) {
                Log::info($consumeName . ' 消费啦===》' . $msg->body);
	        $msg->ack(); //发送ack
            };
            //第四个参数为false意味着要ack (true 意味着不响应ack)
            $channel->basic_consume($queue, '', false, false, false, false, $callback);
            while ($channel->is_open()) { //一直监听
                $channel->wait();
            }
            $channel->close();
            $connection->close();
        } catch (\Exception $e) {
            Log::error("消费者消费消息异常：", [
                'method' => __METHOD__,
                'respone' => $e->getMessage() ?? ""
            ]);
        }
    }

当运行消费者代码的时候报错：PRECONDITION_FAILED - parameters for queue 'record-queue' in vhost '/' not equivalent

解决办法就是在消费者队列声明时，加上可持久化参数。

$channel->queue_declare($queue, false, true, false, false);

基本这种问题都是生产者与消费者两边的配置设置不一样导致的！
