我正在尝试通过 CPanel 上的计划任务创建到 CloudAMQP 的连接，当我通过 SSH 连接到服务器并手动运行脚本时，它工作正常，但是当我尝试通过调度程序运行时，我得到了这个：
PHP Fatal error: Uncaught PhpAmqpLib\Exception\AMQPIOException: stream_socket_client(): unable to connect to tcp://xxxxx.rmq.cloudamqp.com:5672 (Connection refused) in /home/sites/xx/x/xxx/public_html/vendor/php-amqplib/php-amqplib/PhpAmqpLib/Wire/IO/StreamIO.php:111

我的 PHP 代码如下所示：
$url = parse_url("amqps://xxxxx:paswordherexxxs@lionhead.rmq.cloudamqp.com/somethinglikethis");
$vhost = substr($url['path'], 1);
$conn = new AMQPStreamConnection("$url['host']", 5672, $url['user'], $url['pass'], $vhost);
$ch = $conn->channel();
$exchange = 'amq.direct';
$queue = 'queue-name';
$ch->queue_declare($queue, false, true, false, false);
$ch->exchange_declare($exchange, 'direct
老实说，我很难过。第一个大型 PHP 项目（学习编码），我迷路了。
