[PHP知识库]Hyperf 多进程模式下进程间的通信

单Swoole也差不多，就是监听OnPipeMessage事件和sendMessage发送消息。

注册一个监听器监听OnPipeMessage和PipeMessage 事件

use Hyperf\Event\Contract\ListenerInterface;
use Hyperf\Framework\Event\OnPipeMessage;
use Hyperf\Process\Event\PipeMessage as UserProcessPipeMessage;

class OnPipeMessageListener implements ListenerInterface
{
    private $container;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }
    public function listen(): array
    {
        return [
            OnPipeMessage::class,
            UserProcessPipeMessage::class,
        ];
    }
    public function process(object $event)
    {
        if ($event instanceof OnPipeMessage || $event instanceof UserProcessPipeMessage) {
        	if($event->data instanceof MyOnPipeMessage){ //$event->data 就是发送来的数据
					//进行你的操作
			}
        }
    }
}

向其他进程发送数据

use Swoole\Server;
use Hyperf\Process\ProcessCollector;

......

$server = $this->container->get(Server::class);
//获取子进程编号
$workerCount = $server->setting['worker_num'] + ($server->setting['task_worker_num'] ?? 0) - 1;
if ($workerCount > 0) {
	for ($workerId = 0; $workerId <= $workerCount; ++$workerId) { //向其他子进程发送消息
		if ($server->worker_id != $workerId) {
				$server->sendMessage(new MyPipeMessage('message'), $workerId);
		}
	}
}
//向其他进程发送消息
if (class_exists(ProcessCollector::class) && !ProcessCollector::isEmpty()) {
	$processes = ProcessCollector::all();
	if ($processes) {
		$string = serialize(new MyPipeMessage('message'));
		foreach ($processes as $process) {
			$process->exportSocket()->send($string, 10);
		}
	}
}
