wlanapi怎么获取当前连接的wifi名

你可以使用`Wlanapi`库中的`WlanQueryInterface`函数和`WlanGetProfile`函数来获取当前连接的WiFi名称。具体步骤如下：

1. 首先使用`WlanOpenHandle`函数打开一个句柄。

2. 然后使用`WlanEnumInterfaces`函数获取当前计算机的无线网络接口。

3. 使用`WlanQueryInterface`函数查询接口状态，判断是否连接到WiFi网络。

4. 如果连接到WiFi网络，则调用`WlanGetProfile`函数获取当前连接的WiFi名称。

以下是示例代码：

#include <Windows.h>
#include <Wlanapi.h>
#include <iostream>
#pragma comment(lib, "Wlanapi.lib")

int main()
{
    DWORD dwMaxClient = 2; // 最大客户端数量
    HANDLE hClient = NULL;
    PWLAN_INTERFACE_INFO_LIST pIfList = NULL;
    PWLAN_INTERFACE_INFO pIfInfo = NULL;
    DWORD dwRetVal = 0;
    DWORD dwInterfaceIndex = 0;
    WLAN_INTERFACE_STATE wlanInterfaceState = WlanInterfaceStateNotReady;
    WCHAR profileName[256];
    DWORD pdwDataSize = sizeof(profileName);
    DWORD dwFlags = 0;

    // 打开句柄
    dwRetVal = WlanOpenHandle(dwMaxClient, NULL, &dwFlags, &hClient);
    if (dwRetVal != ERROR_SUCCESS)
    {
        std::cerr << "WlanOpenHandle failed with error: " << dwRetVal << std::endl;
        return 1;
    }

    // 枚举接口
    dwRetVal = WlanEnumInterfaces(hClient, NULL, &pIfList);
    if (dwRetVal != ERROR_SUCCESS)
    {
        std::cerr << "WlanEnumInterfaces failed with error: " << dwRetVal << std::endl;
        WlanCloseHandle(hClient, NULL);
        return 1;
    }

    // 遍历接口
    for (DWORD i = 0; i < pIfList->dwNumberOfItems; i++)
    {
        pIfInfo = &pIfList->InterfaceInfo[i];

        // 查询接口状态
        dwRetVal = WlanQueryInterface(hClient, &pIfInfo->InterfaceGuid, wlan_intf_opcode_interface_state, NULL, &pdwDataSize, (PVOID*)&wlanInterfaceState, NULL);
        if (dwRetVal != ERROR_SUCCESS)
        {
            std::cerr << "WlanQueryInterface failed with error: " << dwRetVal << std::endl;
            WlanFreeMemory(pIfList);
            WlanCloseHandle(hClient, NULL);
            return 1;
        }

        // 如果接口连接到WiFi网络，则获取WiFi名称
        if (wlanInterfaceState == WlanInterfaceStateConnected)
        {
            dwRetVal = WlanGetProfile(hClient, &pIfInfo->InterfaceGuid, NULL, profileName, &pdwDataSize, NULL, &dwFlags);
            if (dwRetVal != ERROR_SUCCESS)
            {
                std::cerr << "WlanGetProfile failed with error: " << dwRetVal << std::endl;
                WlanFreeMemory(pIfList);
                WlanCloseHandle(hClient, NULL);
                return 1;
            }
            std::wcout << "Current WiFi name is: " << profileName << std::endl;
            break;
        }
    }

    WlanFreeMemory(pIfList);
    WlanCloseHandle(hClient, NULL);
    return 0;
}

这段代码会输出当前连接的WiFi名称。注意，由于使用了`Wlanapi`库，需要在编译时链接`Wlanapi.lib`库文件。
