Qt5获取网卡/IP等信息
参考网址：http://blog.csdn.net/wjs1033/article/details/22697063
1、环境 Win7x64、Qt5.5.1(x86)、vs2013_ultimate_up5(x86)
1.1、?.h / ?.cpp 都保存成“UTF-8 + BOM”格式（这样，源码里面中文/特殊符号，使用中文注释，就不会有 error或warnning了）
1.2、?.h / ?.cpp 都保存成“UTF-8 + BOM”格式 的话，qDebug()输出中文的时候 全是乱码...
?.h / ?.cpp 都保存成“UTF-8” 格式 的话，qDebug()输出中文的时候 小部分是乱码...
ZC: 暂时 先将 ?.h / ?.cpp 都保存成“UTF-8”格式，以后再研究 这些字符串编码的 中文乱码的事情吧...

3.2、只枚举ip地址的简洁方式
"169.254.85.141"
"192.168.1.233"
"169.254.9.254"
"192.168.131.1"
"192.168.181.1"
"127.0.0.1"
3.3、获取本机主机名 及 IPv4地址 (这里的 控制台输出 中文会有乱码)
"本地主机???: " "33-PC"
IP(IPv4Protocol) : "192.168.1.233"
IP(IPv4Protocol) : "192.168.131.1"
IP(IPv4Protocol) : "192.168.181.1"
3.4、通过 主机名 获取IP地址
LookupHostZ - IP(IPv4Protocol) : "180.97.33.108"
LookupHostZ - IP(IPv4Protocol) : "180.97.33.107"
"www.baidu.com"
3.5、通过IP地址 反向查询 主机名 (这个执行的时候，用时较长)
LookupHostZ - IP(IPv4Protocol) : "192.168.1.201"
"ZHEJIANG001"
3.6、
4、获取本机的 第一个IPv4地址的字符串 (Windows下)
传入参数：_strNetworkInterfaceHumanReadableName : 网络接口卡的名称(类似"无线网络连接"、"本地连接"等)
QString Widget::getIP(QString _strNetworkInterfaceHumanReadableName) { //QString str01 = QString::fromLocal8Bit("本地连接"); QList<QNetworkInterface> networkInterface = QNetworkInterface::allInterfaces(); foreach (QNetworkInterface intf, networkInterface) { bool b = false; if (_strNetworkInterfaceHumanReadableName == NULL) b = true; else { QString str = intf.humanReadableName(); if (str.startsWith(_strNetworkInterfaceHumanReadableName, Qt::CaseInsensitive)) b = true; } if (b) { QList<QNetworkAddressEntry> listNAE = intf.addressEntries(); foreach (QNetworkAddressEntry nae, listNAE) { QHostAddress ha = nae.ip(); if (ha.protocol() == QAbstractSocket::IPv4Protocol) return ha.toString(); } } } return NULL; }
