访问受PHP保护的对象属性(haproxy） - Access PHP protected object property (haproxy)

Access PHP protected object property (haproxy)

我使用的是这个库的修改版本(https://github.com/kamermans/HAProxyAPI)连接到我的所有负载平衡器实例。但是，要知道连接的服务器是活动实例还是备份实例，我需要从统计信息中寻址"bck"属性。（我无法使用$loadbalancer['haproxy_stats']->info->line->data->bck访问它）

注意这个属性：$loadbalancer['haproxy_stats']->health->backup。不是我需要的，这只指示此负载平衡器中是否存在备份服务器。

如何访问此属性？

示例Haproxy Stats来自：Haproxy Stats：：get（$exec）->getServiceStats（$interface，$server）；

结果（print_r）如下所示：

对象继续，但有字符限制。。。

如果为它创建了一个问题，这个问题会很快得到解决，但迟做总比不做好。我想：）

这确实是正确的财产：

$loadbalancer['haproxy_stats']->health->backup

但是，如果您正在检查负载平衡器BACKEND的统计数据，它只会返回备份节点的数量。如果你想知道单个节点是活动的还是备份的，你需要像这样迭代它们：

foreach ($stats->getBackendNames() as $backend) {
    foreach ($stats->getServerNames($backend) as $server) {
        $service = $stats->getServiceStats($backend, $server);
        echo "$backend:$server'n";
        echo "  Active: {$service->health->active}'n";
        echo "  Backup: {$service->health->backup}'n";
        echo "  Health: {$service->health->status}'n'n";
    }
}

这将产生这样的输出：
