在需要對計算機進行標識的場景下，我們一般會選擇獲取一些硬件信息。然而CPU序列號可能有重復、網卡MAC地址和計算機名又能被輕易地修改，所以其中最可靠的應該就是硬盤序列號了。Windows下硬盤序列號的獲取本身并不復雜，而關鍵在于如何在無需權限提升的情況下獲取到硬盤序列號。為了解決這個問題，我也查了很多資料，基本上各大博客中貼出的都是需要權限提升的代碼。
最終，在DiskID32的源碼中，我找到了不提權獲取硬盤序列號的辦法。不過其源碼只能使用MBCS多字節字符集方式編譯，而無法使用Unicode字符集編譯，為此，我進行了一些修改，使之兼容兩種方式。下面將經過我修改、測試后的代碼貼出來，供大家參考。
其中，獲取硬盤序列號的函數命名為GetHDSerial，該函數依賴flipAndCodeBytes函數。前者使用說明如下：
#include <locale.h>
#include <tchar.h>
#include <windows.h>
#include <stdio.h>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;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){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){k =
0;}buf[k] =
'\0';
if (flip)
for (j =
0; j < k; j +=
2){
char t = buf[j];buf[j] = buf[j +
1];buf[j +
1] = t;}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;
}
