在需要对计算机进行标识的场景下,我们一般会选择获取一些硬件信息。然而CPU序列号可能有重复、网卡MAC地址和计算机名又能被轻易地修改,所以其中最可靠的应该就是硬盘序列号了。Windows下硬盘序列号的获取本身并不复杂,而关键在于如何在无需权限提升的情况下获取到硬盘序列号。为了解决这个问题,我也查了很多资料,基本上各大博客中贴出的都是需要权限提升的代码。
最终,在DiskID32的源码中,我找到了不提权获取硬盘序列号的办法。不过其源码只能使用MBCS多字节字符集方式编译,而无法使用Unicode字符集编译,为此,我进行了一些修改,使之兼容两种方式。下面将经过我修改、测试后的代码贴出来,供大家参考。
其中,获取硬盘序列号的函数命名为GetHDSerial,该函数依赖flipAndCodeBytes函数。前者使用说明如下:
参数:
返回值:成功获取到的硬盘序列号长度,为0表示获取失败

char * flipAndCodeBytes(const char * str,
int pos,
int flip,
char * buf)
{
int i;
int j = 0;
int k = 0;
buf[0] = '\0';
if (pos <= 0)
return buf;
if (!j)
{
char p = 0;
// First try to gather all characters representing hex digits only.
j = 1;
k = 0;
buf[k] = 0;
for (i = pos; j && str[i] != '\0'; ++i)
{
char c = tolower(str[i]);
if (isspace(c))
c = '0';
++p;
buf[k] <<= 4;
if (c >= '0' && c <= '9')
buf[k] |= (unsigned char)(c - '0');
else if (c >= 'a' && c <= 'f')
buf[k] |= (unsigned char)(c - 'a' + 10);
else
{
j = 0;
break;
}
if (p == 2)
{
if (buf[k] != '\0' && !isprint(buf[k]))
{
j = 0;
break;
}
++k;
p = 0;
buf[k] = 0;
}
}
}
if (!j)
{
// There are non-digit characters, gather them as is.
j = 1;
k = 0;
for (i = pos; j && str[i] != '\0'; ++i)
{
char c = str[i];
if (!isprint(c))
{
j = 0;
break;
}
buf[k++] = c;
}
}
if (!j)
{
// The characters are not there or are not printable.
k = 0;
}
buf[k] = '\0';
if (flip)
// Flip adjacent characters
for (j = 0; j < k; j += 2)
{
char t = buf[j];
buf[j] = buf[j + 1];
buf[j + 1] = t;
}
// Trim any beginning and end space
i = j = -1;
for (k = 0; buf[k] != '\0'; ++k)
{
if (!isspace(buf[k]))
{
if (i < 0)
i = k;
j = k;
}
}
if ((i >= 0) && (j >= 0))
{
for (k = i; (k <= j) && (buf[k] != '\0'); ++k)
buf[k - i] = buf[k];
buf[k - i] = '\0';
}
return buf;
}
/************************************************************************
GetHDSerial:用于获取指定编号的硬盘序列号,无需任何权限提升
参数:
PCHAR pszIDBuff:传入的字符串缓冲区,用于接收硬盘序列号
int nBuffLen:传入的字符串缓冲区大小,当硬盘序列号大于该值时,只复制nBuffLen长度
int nDriveID:要获取的驱动器编号,从0开始,到15为止
返回值:
成功获取到的硬盘序列号长度,为0表示获取失败
