Laravel artisan: 每秒监听命令

Question

我有两个使用 AMQP 进行通信的微服务。

我用bschmitt/laravel-amqphttps://github.com/bschmitt/laravel-amqp.

我创建了一个将消息发布到队列的操作。

然后我创建了 artisan 命令，它使用队列中的消息。出版商示例：

Amqp::publish('', $user->toJson() , ['queue' => 'MS:USER:CREATED']);

消费者示例：

Amqp::consume('MS:USER:CREATED', function ($message, $resolver) {
                $result = json_decode($message->body);
                    Log::info($result);
                    $resolver->acknowledge($message);

                    $resolver->stopWhenProcessed();

            });

我需要每秒听这个命令。为此，我使用主管。

主管配置示例：

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /home/user/Projects/other/user/artisan ms:user:created
autostart=true
autorestart=true
user=user
numprocs=8
redirect_stderr=true
stdout_logfile=/home/user/Projects/other/user/worker.log

但主管启动并在几秒钟后停止。这是我重启主管时的错误输出：

laravel-worker:laravel-worker_02: ERROR (spawn error)
laravel-worker:laravel-worker_06: ERROR (spawn error)
laravel-worker:laravel-worker_00: ERROR (spawn error)
laravel-worker:laravel-worker_01: ERROR (spawn error)
laravel-worker:laravel-worker_04: ERROR (spawn error)
laravel-worker:laravel-worker_07: ERROR (spawn error)
laravel-worker:laravel-worker_03: ERROR (spawn error)
laravel-worker:laravel-worker_05: ERROR (spawn error)

然后为了获取消息，我需要每次都重新启动 supervisor。

我还知道另一种方法：

包装 Amqp::consume 并为此使用 crontab。

示例：

 while (true) {
            Amqp::consume('MS:USER:CREATED', function ($message, $resolver) {

//some part of code
});
   sleep(1);
        }

这种方法可行，但我认为这不是个好主意。

也许在与主管的接触中，我对这种情况的配置有误。

如有任何帮助，我将不胜感激

您可以通过在主管配置命令Bash中使用 while 循环来做到这一点

[program:ms-user-created]
process_name=%(program_name)s_%(process_num)02d
command=/bin/sh -c "while [ true ]; do (php /home/user/Projects/other/user/artisan ms:user:created &); sleep 1; done"
autostart=true
autorestart=true
numprocs=2
user=www-data
redirect_stderr=true
