Qt QProcess如何在标准中写入？

#include <QCoreApplication>
#include <QProcess>

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

    QProcess process;
    process.start("your_command"); // 替换为你要执行的命令

    if (process.waitForStarted())
    {
        // 写入数据到标准输入
        process.write("Hello, QProcess!");

        // 关闭标准输入
        process.closeWriteChannel();

        // 等待进程结束
        process.waitForFinished();

        // 读取进程输出
        QByteArray output = process.readAll();
        qDebug() << "Process output:" << output;
    }

    return a.exec();
}
