window下获取CPU温度 C++代码

你可以使用第三方库来获取Windows下的CPU温度，以下是一个示例的C++代码：

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

#pragma comment(lib, "pdh.lib")

float GetCpuTemperature()
{
    HQUERY hQuery;
    PDH_STATUS pdhStatus;
    HCOUNTER hCounter;
    DWORD dwType;
    PPDH_FMT_COUNTERVALUE pValue;

    pdhStatus = PdhOpenQuery(NULL, NULL, &hQuery);
    if (pdhStatus != ERROR_SUCCESS)
    {
        std::cout << "PdhOpenQuery failed with status: " << pdhStatus << std::endl;
        return -1.0f;
    }

    pdhStatus = PdhAddCounter(hQuery, L"\\Processor(_Total)\\% Processor Time", NULL, &hCounter);
    if (pdhStatus != ERROR_SUCCESS)
    {
        std::cout << "PdhAddCounter failed with status: " << pdhStatus << std::endl;
        PdhCloseQuery(hQuery);
        return -1.0f;
    }

    pdhStatus = PdhCollectQueryData(hQuery);
    if (pdhStatus != ERROR_SUCCESS)
    {
        std::cout << "PdhCollectQueryData failed with status: " << pdhStatus << std::endl;
        PdhCloseQuery(hQuery);
        return -1.0f;
    }

    Sleep(1000); // 等待一秒钟

    pdhStatus = PdhCollectQueryData(hQuery);
    if (pdhStatus != ERROR_SUCCESS)
    {
        std::cout << "PdhCollectQueryData failed with status: " << pdhStatus << std::endl;
        PdhCloseQuery(hQuery);
        return -1.0f;
    }

    pdhStatus = PdhGetFormattedCounterValue(hCounter, PDH_FMT_DOUBLE, &dwType, pValue);
    if (pdhStatus != ERROR_SUCCESS)
    {
        std::cout << "PdhGetFormattedCounterValue failed with status: " << pdhStatus << std::endl;
        PdhCloseQuery(hQuery);
        return -1.0f;
    }

    PdhCloseQuery(hQuery);

    // 假设CPU温度与CPU使用率成正比，可以将CPU使用率作为温度值返回
    return static_cast<float>(pValue->doubleValue);
}

int main()
{
    float temperature = GetCpuTemperature();
    if (temperature != -1.0f)
    {
        std::cout << "CPU Temperature: " << temperature << " %" << std::endl;
    }

    return 0;
}

请注意，该代码使用了 Windows PDH (Performance Data Helper) API 来获取CPU使用率，并假设CPU温度与使用率成正比。这只是一个简单的示例，实际情况可能因硬件和操作系统的不同而有所区别。你可能需要根据具体的硬件和操作系统来选择适合的方法来获取CPU温度。
