WMI - 取本地计算机信息
概述
在看windows下取本地计算机特征码的资料.
以前也取过, 都是用WIN32API来取. 这样取的不全. 有些信息取不到.
现在看的资料是用WMI接口取本地计算机信息, 这样取的全.
还是要有足够的思考和实验时间才能整出好一些的思路和产出, 如果被赶着往前走, 只考虑将眼前的事情凑合干完, 会导致好多细节考虑不到或不是较好的实现思路.
如果是被迫进行一项任务, 即使自己有心将细节做好, 也没有时间去做(思考, 查资料, 做实验).
资料中取硬盘特征码时, 没有判断硬盘是否为可插拔硬盘.
我必须要取固定硬盘的特征码, 做了实验, MediaType的值为 ‘Fixed hard disk media’ 就是固定硬盘.
我还需要取固定网卡的特征码, 资料中没有.
做了实验, 取网卡的类为 Win32_NetworkAdapter.
满足以下条件, 就是固定网卡.
- 必须有GUID值.
- PNPDeviceID值中的类别必须属于 PCI, BTH
用WMI能取的计算机信息还很多, 可以参考https://learn.microsoft.com/en-us/windows/win32/cimwin32prov/win32-networkadapter
这个笔记可以用WMI接口取指定WMI类的计算机信息, 指定上图中4个大类别的不同子类, 结合官方文档中说的类成员名称和类型, 就可以取到MS官方提供的其他计算机信息.
如果自己有时间, 可以做个程序, 将MS提供的WMI类信息全部显示出来, 应该里面有不少好东西.
不过编程方面, 重复的不行, 估计很累.
另外, 官方给的类成员的类型可能不对, 需要自己根据实际接口返回的.vt来修正. 我在取硬盘和网卡信息时, 已经发现有些官方给的类成员类型不对. 如果是通过WMI接口取大量信息时, 最好加入断言, 这样的话, 如果从WMI接口返回的类成员信息的类型不对时, 就可以及时发现止损.
if (VT_BOOL != vt_prop.vt)
{
_ASSERT(FALSE);
break;
}
官方提供的VT类型列表为 https://learn.microsoft.com/en-us/windows/win32/api/wtypes/ne-wtypes-varenum
网上有一些公版工具可以改硬盘序列号, 网卡序列号. 但是用WMI可以取的硬件信息很多, 可以找一些公版工具无法改的信息作为硬件特征码.
只要是物理上的硬件信息, 这个硬件即使没有被用户使用(e.g. 被停用的物理网卡), 作为硬件特征码也挺靠谱的.
笔记
写了测试程序, 环境vs2019 vc++ console
测试效果
我本地有2个固定硬盘, 3个固定网卡
