篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Qt之获取本机网络信息(MAC, IP等等,很全)相关的知识,希望对你有一定的参考价值。
经常使用命令行来查看一些计算机的配置信息。
- QHostInfo
- QHostAddress
- QNetworkInterface
- QNetworkAddressEntry
QString name = qgetenv("USERNAME");
qDebug() << "User Name:" << name;
//QHostInfo类作用,获取主机名,也可以通过主机名来查找IP地址,或者通过IP地址来反向查找主机名。
QString localHostName = QHostInfo::localHostName();
qDebug() << "LocalHostName:" << localHostName;
//获取IP地址
QHostInfo info = QHostInfo::fromName(localHostName);
qDebug() << "IP Address:" << info.addresses();
foreach(QHostAddress address, info.addresses())
{
if (address.protocol() == QAbstractSocket::IPv4Protocol)
qDebug() << "IPv4 Address:" << address.toString();
}
foreach (QHostAddress address, QNetworkInterface::allAddresses())
{
qDebug() << "Address:" << address;
}
LocalHostName: "wangl-d-pc"
IP Address: (QHostAddress("fe80::396e:183d:aac6:f7f2") , QHostAddress( "192.168.118.55" ) )
IPv4 Address: "192.168.118.55"
Address: QHostAddress( "fe80::396e:183d:aac6:f7f2" )
Address: QHostAddress( "192.168.118.55" )
Address: QHostAddress( "::1" )
Address: QHostAddress( "127.0.0.1" )
Address: QHostAddress( "fe80::5efe:c0a8:7637" )
Address: QHostAddress( "fe80::e0:0:0:0" )
3.获取设备名、MAC地址、子网掩码、广播地址等
//获取所有网络接口的列表
foreach (QNetworkInterface netInterface, QNetworkInterface::allInterfaces())
{
//设备名
qDebug() << "Device:" << netInterface.name();
//MAC地址
qDebug() << "HardwareAddress:" << netInterface.hardwareAddress();
QList entryList = netInterface.addressEntries();
//遍历每一个IP地址(每个包含一个IP地址,一个子网掩码和一个广播地址)
foreach(QNetworkAddressEntry entry, entryList)
{
//IP地址
qDebug() << "IP Address:" << entry.ip().toString();
//子网掩码
qDebug() << "Netmask:" << entry.netmask().toString();
//广播地址
qDebug() << "Broadcast:" << entry.broadcast().toString();
}
}
Device: "{4C5C2613-C18F-416A-A21F-47B707C3B935}"
HardwareAddress: "74:D4:35:1B:A6:2F"
IP Address: "fe80::396e:183d:aac6:f7f2"
Netmask: "ffff:ffff:ffff:ffff::"
Broadcast: ""
IP Address: "192.168.118.55"
Netmask: "255.255.255.0"
Broadcast: "192.168.118.255"
Device: "{846EE342-7039-11DE-9D20-806E6F6E6963}"
HardwareAddress: ""
IP Address: "::1"
Netmask: "ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff"
Broadcast: ""
IP Address: "127.0.0.1"
Netmask: ""
Broadcast: ""
Device: "{539F3167-F67C-432D-8904-34129F3F5521}"
HardwareAddress: "00:00:00:00:00:00:00:E0"
IP Address: "fe80::5efe:c0a8:7637"
Netmask: "ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff"
Broadcast: ""
Device: "{5DECB4C5-20AC-4BD6-A685-9FE608ED6EF5}"
HardwareAddress: "00:00:00:00:00:00:00:E0"
IP Address: "fe80::e0:0:0:0"
Netmask: "ffff:ffff:ffff:ffff::"
Broadcast: ""
