主要是通过时间进行计算，然后时间上做限制，

在main.cpp里面固定使用期限

 QString starttime = "2019-04-19 12:00:01";
    QString endtime = QDateTime::currentDateTime().toString("yyyy-MM-dd hh:mm:ss");
    QDateTime start = QDateTime::fromString(starttime, "yyyy-MM-dd hh:mm:ss");
    QDateTime end = QDateTime::fromString(endtime, "yyyy-MM-dd hh:mm:ss");
    uint stime = start.toTime_t();
    uint etime = end.toTime_t();
    int ndaysec = 24*60*60;
    int day = (etime - stime)/(ndaysec) + ((etime - stime)%(ndaysec)+(ndaysec-1))/(ndaysec) - 1;
    qDebug() << "Day ---------------------------------------------------- " << day;
    if(day > 60){
        QXMessageBox msgBox;
        msgBox.setlabelTitleStr(QString::fromLocal8Bit("警告"));
        msgBox.setlabelMsgStr(QString("程序启动失败，请联系开发人员确认!"));
        msgBox.exec();
    }else{
        QXServerPross->start("bash");
        QXServerPross->waitForStarted();
        QString midstr = "cd " + exepath + "\n";
        QXServerPross->write(midstr.toStdString().c_str());
        QString actstr = "./QXServer\n";
        QXServerPross->write(actstr.toStdString().c_str());
#ifdef Q_PROCESSOR_X86
        time->start(10000);
#else
        time->start(1000);
#endif
    }
