Qt之获取本机网络信息(MAC, IP等等,很全)
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: ""
