rabbitmq php 发送延迟消息 java 进行消费

 

 

// ------- 延迟队列 php 需要安装好几个扩展  php 生产者
$connection = new AMQPStreamConnection('xxxxx', 5672, 'guest', 'guest');
$channel = $connection->channel();

// 发送消息到交换机，并设置 x-delay 属性

$messageData = ['msg' => json_encode(['a'=>111])];
$messageBody = json_encode($messageData);
$headers = ['x-delay' => 10000]; // 10 秒延迟
$message = new AMQPMessage($messageBody, [
'delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT,
'application_headers' => new \PhpAmqpLib\Wire\AMQPTable(['x-delay' => $headers['x-delay']])
]);


// 推送延迟消息到延迟交换机
$channel->basic_publish($message, 'delayed-exchange', 'delayed-queue');

// 关闭连接
$channel->close();

$connection->close();

 

 

 

// php 消费者 单独一个文件  php -d display_errors=on mq.php 这个命令可以查看具体报错信息等错误
