不用打开控制台窗口就能在qt程序中执行系统命令的方法

#include <QCoreApplication>
#include <QProcess>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QProcess process;
    process.start("system_command"); // 替换为要执行的系统命令
    process.waitForFinished(-1); // 等待命令执行完成

    QString output = process.readAllStandardOutput(); // 获取命令输出结果
    QString error = process.readAllStandardError(); // 获取命令错误信息

    qDebug() << "Output: " << output;
    qDebug() << "Error: " << error;

    return a.exec();
}

#include <QCoreApplication>
#include <QProcess>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QByteArray command = "system_command"; // 替换为要执行的系统命令

    QProcess process;
    process.start(command.data());
    process.waitForFinished(-1);

    QString output = process.readAllStandardOutput();
    QString error = process.readAllStandardError();

    qDebug() << "Output: " << output;
    qDebug() << "Error: " << error;

    return a.exec();
}
