【已解决】gateway-worker的onClose得不到$_SESSION数据

public static function onMessage($client_id, $message)
{
    $msg = json_decode($message,1);
    $_SESSION['closeFlag'] = 123;
    if(!is_array($msg)){
        Gateway::closeClient($client_id);
    }
}

public static function onClose($client_id)
{
    echo "关闭gateway :{$_SESSION['closeFlag']} \n";
}
