Qt5获取本机所有IP和串口

note

• 环境： windows
• 需要项目添加 serialport 和 network 模块
• QToolkits 扩展中......

结果

IP

• IP 获取结果
  

本机串口获取

• 串口获取结果
  

范例代码

• 已经封装好， copy即可使用

获取本机IP调用范例

	using namespace oct_tk;
	QToolkits tk;

	qDebug() << "\n\n\n ================== ip all ==================";
	{
		const QStringList&& iplist = tk.local_ip(QToolkits::IP_VERSION::IPVX);
		for (const auto& item : iplist)
		{
			qDebug() << "ip=" << item;
		}
	}

	qDebug() << "\n\n\n ================== ip V4 ==================";
	{
		const QStringList&& iplist = tk.local_ip(QToolkits::IP_VERSION::IPV4);
		for (const auto& item : iplist)
		{
			qDebug() << "ip=" << item;
		}
	}

	qDebug() << "\n\n\n ================== ip V6 ==================";
	{
		const QStringList&& iplist = tk.local_ip(QToolkits::IP_VERSION::IPV6);
		for (const auto& item : iplist)
		{
			qDebug() << "ip=" << item;
		}
	}

串口获取使用范例

	qDebug() << "\n\n\n ================== serial port ==================";
	{
		const QStringList&& sp_list  = tk.serial_port();
		for (const auto& item : sp_list)
		{
			qDebug() << "sp=" << item;
		}
	}
