Question

我有一台服务器，它使用HTTP请求发布到我的网站并等待响应。程序中名为heartbeat（）的函数将每3秒向我的网站发送一次HTTP请求。

我无法设法获取HTTP请求库，因此我必须在线查看C ++中的自定义代码才能完成。它工作但我发现，如果我在2天后离开服务器，我的网络完全放慢了速度。是的，这肯定是我的服务器这样做，因为我一直在看我的网络，如果我没有我的服务器2天，这是完全没问题的。这是服务器。

老实说我真的迷失了其他可能造成这种情况的原因，所以我想知道是否有人可以查看我的心跳/ http功能，看看是否有任何可能导致某种数据包的缺陷自从此功能每3秒调用一次后，泄漏或可能会在2天后减慢网络速度的事情。

    while(1){

            heartClock.restart();
            sf::Thread heartThread(std::bind(&MasterServerHandler::heartbeat_server, cst::masterIP, tcp_port, udp_port, match->num_players(), false));
            heartThread.launch();
        }
    }

}

    return response;

}

或者，如果有人知道更好的HTTP请求函数，那就太棒了。
