我这个 API 设计得怎么样？

    void WebSocketRequestHandler::doGET()
    {
        if (path != QString::fromUtf8("/")) {
            sendError(HttpStatus::NotFound);
            return;
        }
        if (!switchToWebSocket()) {
            sendError(HttpStatus::NotImplemented);
            return;
        }
        endHeader();

        WebSocketConnection conn(request, body, WebSocketConnection::Server);
        WebSocketConnection::FrameType type;
        while (true) {
            const QByteArray &packet = conn.recv(&type);
            if (packet.isEmpty()) {
                qDebug() << "received empty packet.";
                return;
            }
            qDebug() << type << packet;
            if (!conn.send(packet)) {
                qDebug() << "can not send echo packet.";
                return;
            }
        }
    }

    int main()
    {
        TcpServer<WebSocketRequestHandler> httpd(HostAddress::AnyIPv4, 8000);
        return httpd.serveForever() ? 0 : 1;
    }

我发现大多数 C++ 的网络库都设计得很烦杂。
