swoole_server->sendMessage

此函数可以向任意worker进程或者task进程发送消息。在非主进程和管理进程中可调用。收到消息的进程会触发onPipeMessage事件。

bool swoole_server->sendMessage(string $message, int $dst_worker_id);

• $message为发送的消息数据内容
• $dst_worker_id为目标进程的ID，范围是0 ~ (worker_num + task_worker_num - 1)

sendMessage接口在swoole-1.7.9以上版本可用
使用sendMessage必须注册onPipeMessage事件回调函数

实例

$serv = new swoole_server("0.0.0.0", 9501);
$serv->set(array(
    'worker_num' => 2,
    'task_worker_num' => 2,
));
$serv->on('pipeMessage', function($serv, $src_worker_id, $data) {
    echo "#{$serv->worker_id} message from #$src_worker_id: $datan";
});
$serv->on('task', function ($serv, $task_id, $from_id, $data){
    var_dump($task_id, $from_id, $data);
});
$serv->on('finish', function ($serv, $fd, $from_id){

});
$serv->on('receive', function (swoole_server $serv, $fd, $from_id, $data) {
    if (trim($data) == 'task')
    {
        $serv->task("async task coming");
    }
    else
    {
        $worker_id = 1 - $serv->worker_id;
        $serv->sendMessage("hello task process", $worker_id);
    }
});

$serv->start();
