這篇文章主要為大家詳細(xì)介紹了如何利用qt自帶的QNetworkInterface接口以及c++Iphlpapi庫(kù),獲取當(dāng)前windows電腦下的網(wǎng)卡信息,需要的可以參考下

本文將利用qt自帶的QNetworkInterface接口以及c++Iphlpapi庫(kù)，獲取當(dāng)前windows電腦下的網(wǎng)卡型號(hào)、物理地址、ip地址、子網(wǎng)掩碼、網(wǎng)關(guān)等信息。

#include <QtNetwork/QNetworkInterface>

#include <iostream>
#include <Windows.h>
#include <iphlpapi.h>

//獲取對(duì)應(yīng)網(wǎng)卡部分信息
BOOL MatchNetcardInfo(UiNetcardVersion &netcardVer)
{
    PIP_ADAPTER_INFO pIPAdapterInfo = new IP_ADAPTER_INFO();
    PIP_ADAPTER_INFO adapters = nullptr;
    ULONG size = sizeof(IP_ADAPTER_INFO);

    int nRet = GetAdaptersInfo(pIPAdapterInfo, &size);


    //pIPAdapterInfo內(nèi)存不夠，重新申請(qǐng)
    if (ERROR_BUFFER_OVERFLOW == nRet)
    {
        delete pIPAdapterInfo;
        pIPAdapterInfo = (PIP_ADAPTER_INFO)new byte[size];
        nRet = GetAdaptersInfo(pIPAdapterInfo, &size);
    }

    if (ERROR_SUCCESS == nRet)
    {
        adapters = pIPAdapterInfo;
        while (adapters)
        {
            //以XX-XX-XX-XX-XX-XX的形式輸出MAC
            char buf[20]{0};
            sprintf(buf, "%02X:%02X:%02X:%02X:%02X:%02X", adapters->Address[0], adapters->Address[1], adapters->Address[2], adapters->Address[3], adapters->Address[4], adapters->Address[5]);

            QString macTmp = buf;
            if(macTmp != netcardVer.macAddr){
                adapters = adapters->Next;
                continue;
            }

            netcardVer.desc = adapters->Description;
            //可能網(wǎng)卡有多IP,因此通過(guò)循環(huán)去判斷
            IP_ADDR_STRING* pIpAddrString = &(adapters->IpAddressList);
            do
            {
                netcardVer.ipAddr = pIpAddrString->IpAddress.String;
                netcardVer.netMask = pIpAddrString->IpMask.String;
                netcardVer.gateway = adapters->GatewayList.IpAddress.String;
                pIpAddrString = pIpAddrString->Next;
            } while (pIpAddrString);

            break;
        }
    }

    //釋放分配的內(nèi)存
    if (pIPAdapterInfo)
        delete pIPAdapterInfo;

    return true;
}

//獲取網(wǎng)卡信息
void GetNetcardInfo(){
    QList<UiNetcardVersion> netcardList;
    netcardList.clear();


    QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();
    foreach(const QNetworkInterface& it, interfaces){

        if(QNetworkInterface::Loopback == it.type())
            continue;

        UiNetcardVersion netcardVer;
        //獲取名稱和mac地址
        netcardVer.name = it.humanReadableName();
        netcardVer.macAddr = it.hardwareAddress();
        //獲取型號(hào)、ip地址、子網(wǎng)掩碼、網(wǎng)關(guān)
        MatchNetcardInfo(netcardVer);
        //添加到容器
        netcardList.append(netcardVer);
    }
}
