环境win7+qt5.13+MinGW32，台式机

直接上步骤了，网上看到的略显啰嗦，就是这么简单直接：

1、头文件 #include "windows.h"，#include "wlanapi.h"

2、.pro设置连接路径（需要根据自己安装路径加载）

LIBS += C:/Qt/Qt5.13.0/Tools/mingw730_32/i686-w64-mingw32\lib\libwlanapi.a

3、显示在combox控件内

ui->cbx_WifiName->clear();HANDLE  hClientHandle;DWORD dwError = ERROR_SUCCESS;//原来我DWORD MFC的数据类型，相当于unsigned longDWORD dwNegotiatedVersion;dwError = WlanOpenHandle(1, nullptr, &dwNegotiatedVersion, &hClientHandle);//连接不成功if (dwError != ERROR_SUCCESS){qDebug()<<"未打开成功！";WlanCloseHandle(hClientHandle,nullptr);return;}PWLAN_INTERFACE_INFO_LIST  pInterfaceList;dwError = WlanEnumInterfaces(hClientHandle, nullptr,&pInterfaceList);//返回值还是DWRD类型的，成功的话是ERROR_SUCCESSif ( dwError != ERROR_SUCCESS ){ErroInf="未发现wifi相关列表！";WlanFreeMemory(pInterfaceList);//释放列表//释放内存,从Native Wifi函数返回的任何内存必须释放WlanCloseHandle(hClientHandle,nullptr);//关闭wlanreturn;}GUID &guid = pInterfaceList->InterfaceInfo[0].InterfaceGuid;PWLAN_AVAILABLE_NETWORK_LIST pWLAN_AVAILABLE_NETWORK_LIST = nullptr;WlanGetAvailableNetworkList(hClientHandle, &guid,2,nullptr, &pWLAN_AVAILABLE_NETWORK_LIST);//添加到comboxfor (int i=0;i<pWLAN_AVAILABLE_NETWORK_LIST->dwNumberOfItems;i++){ui->cbx_WifiName->addItem((char*)(pWLAN_AVAILABLE_NETWORK_LIST->Network[i].dot11Ssid.ucSSID));}

4、上图

读取IP地址

ui->cbx_Ip->clear();QString localHostName = QHostInfo::localHostName();qDebug() <<"localHostName:"<<localHostName;QHostInfo info = QHostInfo::fromName(localHostName);foreach(QHostAddress address,info.addresses()){if(address.protocol() == QAbstractSocket::IPv4Protocol)ui->cbx_Ip->addItem(address.toString());}
