Mac OS X中的唯一硬件ID

Question

Mac OS X开发对我来说是一个相当新的动物,我正在移植一些软件.对于软件许可和注册,我需要能够生成某种硬件ID.它不一定是任何花哨的东西; 以太网MAC地址,硬盘串口,CPU串口等等.

我已经在Windows上覆盖了它,但我对Mac没有任何线索.知道我需要做什么,或者我可以在哪里获取有关此信息的信息会很棒!

编辑:

对于任何对此感兴趣的人,这是我最终使用Qt的QProcess类的代码:

QProcess proc;

QStringList args;
args << "-c" << "ioreg -rd1 -c IOPlatformExpertDevice |  awk '/IOPlatformUUID/ { print $3; }'";
proc.start( "/bin/bash", args );
proc.waitForFinished();

QString uID = proc.readAll();

注意:我正在使用C++.

对于C/C++:

void get_platform_uuid(char * buf, int bufSize) {
    io_registry_entry_t ioRegistryRoot = IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/");
    CFStringRef uuidCf = (CFStringRef) IORegistryEntryCreateCFProperty(ioRegistryRoot, CFSTR(kIOPlatformUUIDKey), kCFAllocatorDefault, 0);
    IOObjectRelease(ioRegistryRoot);
    CFStringGetCString(uuidCf, buf, bufSize, kCFStringEncodingMacRoman);
    CFRelease(uuidCf);    
}

Answer 2

试试这个终端命令:

ioreg -rd1 -c IOPlatformExpertDevice | awk '/IOPlatformUUID/ { split($0, line, "\""); printf("%s\n", line[4]); }'

从这里开始

这是用Cocoa包装的命令(可能会变得更干净):

NSArray * args = [NSArray arrayWithObjects:@"-rd1", @"-c", @"IOPlatformExpertDevice", @"|", @"grep", @"model", nil];
NSTask * task = [NSTask new];
[task setLaunchPath:@"/usr/sbin/ioreg"];
[task setArguments:args];

NSPipe * pipe = [NSPipe new];
[task setStandardOutput:pipe];
[task launch];

NSArray * args2 = [NSArray arrayWithObjects:@"/IOPlatformUUID/ { split($0, line, \"\\\"\"); printf(\"%s\\n\", line[4]); }", nil];
NSTask * task2 = [NSTask new];
[task2 setLaunchPath:@"/usr/bin/awk"];
[task2 setArguments:args2];

NSPipe * pipe2 = [NSPipe new];
[task2 setStandardInput:pipe];
[task2 setStandardOutput:pipe2];
NSFileHandle * fileHandle2 = [pipe2 fileHandleForReading];
[task2 launch];

NSData * data = [fileHandle2 readDataToEndOfFile];
NSString * uuid = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

如果您告诉我们您使用的语言,这将更容易回答.通过SystemConfiguration框架可以在没有任何shell命令的情况下获取信息,如果您想让自己的手真的变脏,也可以通过IOKit获取.

- (NSString*) getMACAddress: (BOOL)stripColons {
    NSMutableString         *macAddress         = nil;
    NSArray                 *allInterfaces      = (NSArray*)SCNetworkInterfaceCopyAll();
    NSEnumerator            *interfaceWalker    = [allInterfaces objectEnumerator];
    SCNetworkInterfaceRef   curInterface        = nil;

    while ( curInterface = (SCNetworkInterfaceRef)[interfaceWalker nextObject] ) {
        if ( [(NSString*)SCNetworkInterfaceGetBSDName(curInterface) isEqualToString:@"en0"] ) {
            macAddress = [[(NSString*)SCNetworkInterfaceGetHardwareAddressString(curInterface) mutableCopy] autorelease];

            if ( stripColons == YES ) {
                [macAddress replaceOccurrencesOfString: @":" withString: @"" options: NSLiteralSearch range: NSMakeRange(0, [macAddress length])];
            }

            break;
        }
    }

    return [[macAddress copy] autorelease];
}

为什么不试试gethostuuid()？以下是Mac OS X系统调用手册中的文档:

名称:

 gethostuuid -- return a unique identifier for the current machine

概要:

 #include <unistd.h>

 int gethostuuid(uuid_t id, const struct timespec *wait);

描述:

gethostuuid()函数返回由id指定的16字节uuid_t,它唯一地标识当前计算机.请注意,gethostuuid()用于生成UUID的硬件标识符本身可以进行修改.

wait参数是指向struct timespec的指针,指定等待结果的最长时间.将tv_sec和tv_nsec字段设置为零意味着无限期地等待直到完成.

返回值:

gethostuuid()函数在成功时返回零,或在出错时返回-1.

错误

如果出现以下情况,gethostuuid()函数将失败:

 [EFAULT]           wait points to memory that is not a valid part of the
                    process address space.

 [EWOULDBLOCK]      The wait timeout expired before the UUID could be
                    obtained.

/*
g++ mac_uuid.cpp -framework CoreFoundation -lIOKit
*/


#include <iostream>
#include <IOKit/IOKitLib.h>

using namespace std;

void get_platform_uuid(char * buf, int bufSize)
{
   io_registry_entry_t ioRegistryRoot = IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/");
   CFStringRef uuidCf = (CFStringRef) IORegistryEntryCreateCFProperty(ioRegistryRoot, CFSTR(kIOPlatformUUIDKey), kCFAllocatorDefault, 0);
   IOObjectRelease(ioRegistryRoot);

   CFRelease(uuidCf);
}
