获取设备唯一标识

windows guid

#include <stdio.h>  
#include <windows.h>
#define GUID_LEN 64  

int main(int argc, char* argv[])  
{  
    printf("test\n");
    char buffer[GUID_LEN] = { 0 };  
    GUID guid;
    printf("guid\n");
    if (CoCreateGuid(&guid))  
    {  
        printf("create guid error\n");
        fprintf(stderr, "create guid error\n");  
        return -1;  
    }
    _snprintf(buffer, sizeof(buffer),  
        "%08X-%04X-%04x-%02X%02X-%02X%02X%02X%02X%02X%02X",  
        guid.Data1, guid.Data2, guid.Data3,  
        guid.Data4[0], guid.Data4[1], guid.Data4[2],  
        guid.Data4[3], guid.Data4[4], guid.Data4[5],  
        guid.Data4[6], guid.Data4[7]);  
    printf("guid: %s\n", buffer);  
    return 0;  
}

编译方法

gcc main.c -o main.exe -lmingw32 -lole32

linux

#include <uuid/uuid.h>  

int main()  
{
    uuid_t uu;  
    int i;  
    uuid_generate( uu );  

    for(i=0;i<16;i++)  
    {  
        printf("%02X-",uu[i]);  
    }  
    printf("\n");  
    return 0;  
}

经测试windows识别码会改变，于是寻找其他资料：

获取uuid命令：wmic csproduct get uuid
(这个貌似是获取主板uuid)

python获取mac地址

#!/usr/bin/python
# get ip
import subprocess
def get_ip():
    args='''ifconfig|grep 'inet addr:'|awk '{print $2}'|awk -F':' '{print $2}'|grep -v "127.0.0.1"'''
    t=subprocess.Popen(args,shell=True,stdout=subprocess.PIPE).communicate()[0]
    print(t, type(t))
    t = str(t)
    return t.split('\n')[0]

# print(get_ip())

# 获取mac唯一地址
def get_max_address():
    import uuid
    node=uuid.getnode()
    print('node:', node)
    mac=uuid.UUID(int=node).hex[-12:]
    return mac

print(get_max_address())
