c/c++获取Windows cpu温度

Question

c++获取Windows cpu温度,好像wmi或者Windows api能实现吗（如果用的是AI，能不能先在自己电脑上运行一下代码，AI的代码大概率是运行不了的）

Answer 1

WMI的话记得有一个，但是Windows api估计要找些开源库才有
WMI（Windows Management Instrumentation）获取Windows操作系统的CPU温度
WMI提供了一种用于获取系统信息的机制，包括CPU温度。你可以使用WMI查询语言（WQL）来获取相关信息。

#include <iostream>
#include <comdef.h>
#include <Wbemidl.h>
using namespace std;

int main() {
    HRESULT hres;

    // 初始化COM库
    hres = CoInitializeEx(0, COINIT_MULTITHREADED);
    if (FAILED(hres)) {
        cout << "Failed to initialize COM library. Error code: " << hex << hres << endl;
        return 1;
    }

    // 设置安全性级别
    hres = CoInitializeSecurity(
        NULL,
        -1,
        NULL,
        NULL,
        RPC_C_AUTHN_LEVEL_DEFAULT,
        RPC_C_IMP_LEVEL_IMPERSONATE,
        NULL,
        EOAC_NONE,
        NULL
    );
    if (FAILED(hres)) {
        cout << "Failed to initialize security. Error code: " << hex << hres << endl;
        CoUninitialize();
        return 1;
    }

    IWbemLocator* pLoc = NULL;
    hres = CoCreateInstance(
        CLSID_WbemLocator,
        0,
        CLSCTX_INPROC_SERVER,
        IID_IWbemLocator,
        (LPVOID*)&pLoc
    );
    if (FAILED(hres)) {
        cout << "Failed to create IWbemLocator object. Error code: " << hex << hres << endl;
        CoUninitialize();
        return 1;
    }

    // 连接WMI
    IWbemServices* pSvc = NULL;
    hres = pLoc->ConnectServer(
        _bstr_t(L"ROOT\\CIMV2"),
        NULL,
        NULL,
        0,
        NULL,
        0,
        0,
        &pSvc
    );
    if (FAILED(hres)) {
        cout << "Failed to connect to WMI. Error code: " << hex << hres << endl;
        pLoc->Release();
        CoUninitialize();
        return 1;
    }

    // 设置代理
    hres = CoSetProxyBlanket(
        pSvc,
        RPC_C_AUTHN_WINNT,
        RPC_C_AUTHZ_NONE,
        NULL,
        RPC_C_AUTHN_LEVEL_CALL,
        RPC_C_IMP_LEVEL_IMPERSONATE,
        NULL,
        EOAC_NONE
    );
    if (FAILED(hres)) {
        cout << "Failed to set proxy blanket. Error code: " << hex << hres << endl;
        pSvc->Release();
        pLoc->Release();
        CoUninitialize();
        return 1;
    }

    // 查询数据
    IEnumWbemClassObject* pEnumerator = NULL;
    hres = pSvc->ExecQuery(
        bstr_t("WQL"),
        bstr_t("SELECT * FROM Win32_PerfFormattedData_Counters_ThermalZoneInformation"),
        WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
        NULL,
        &pEnumerator
    );
    if (FAILED(hres)) {
        cout << "Failed to execute WQL query. Error code: " << hex << hres << endl;
        pSvc->Release();
        pLoc->Release();
        CoUninitialize();
        return 1;
    }

    // 遍历结果
    IWbemClassObject* pclsObj = NULL;
    ULONG uReturn = 0;
    while (pEnumerator) {
        HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturn);
        if (0 == uReturn) {
            break;
        }

        VARIANT vtProp;
        hr = pclsObj->Get(L"Temperature", 0, &vtProp, 0, 0);
        if (SUCCEEDED(hr)) {
            wcout << "CPU Temperature: " << vtProp.uintVal << " degrees Celsius" << endl;
            VariantClear(&vtProp);
        }

        pclsObj->Release();
    }

    // 清理资源
    pSvc->Release();
    pLoc->Release();
    pEnumerator->Release();
    CoUninitialize();

    return 0;
}

这段代码创建了一个与WMI相关的COM对象，连接到WMI，并使用WQL查询Win32_PerfFormattedData_Counters_ThermalZoneInformation类获取CPU温度信息。不同的计算机和操作系统版本可能有所不同，因此需要根据实际情况进行调整。
