前言：在qt中获取CPU和主板唯一序列号，可以在程序构造函数中判断是否与windows中一致，不一致可以直接退出程序，防止程序daoyong。 

一、获取电脑CPU唯一序列号

QString MainPage::get_cpu()
{QString cmd="wmic cpu get processorid";QProcess p;p.start(cmd);p.waitForFinished();QString result = QString::fromLocal8Bit(p.readAllStandardOutput());QStringList list = cmd.split(" ");result = result.remove(list.last(), Qt::CaseInsensitive);result = result.replace("\r", "");result = result.replace("\n", "");result = result.simplified();return result;
}

二、获取电脑主板唯一序列号

QString MainPage::get_main_board()
{QString cmd="wmic baseboard get serialnumber";QProcess p;p.start(cmd);p.waitForFinished();QString result = QString::fromLocal8Bit(p.readAllStandardOutput());QStringList list = cmd.split(" ");result = result.remove(list.last(), Qt::CaseInsensitive);result = result.replace("\r", "");result = result.replace("\n", "");result = result.simplified();return result;
}

三、windows中获取cpu和主板序列号 

首先win加R，输入cmd
输入wmic cpu get processorid，获取CPU唯一序列号。

输入wmic baseboard get serialnumber，获取主板唯一序列号。
