如何在Qt5中将二进制数据写入标准输出

#include <QtCore/QCoreApplication>
#include <QtCore/QDebug>
#include <QtCore/QByteArray>

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

    // 二进制数据
    QByteArray binaryData;
    binaryData.append(0x48); // 添加一个字节数据
    binaryData.append(0x65);
    binaryData.append(0x6c);
    binaryData.append(0x6c);
    binaryData.append(0x6f);

    // 写入标准输出
    qint64 bytesWritten = qInfo().noquote().nospace() << binaryData;

    // 检查写入是否成功
    if (bytesWritten == -1) {
        qWarning() << "Failed to write binary data to standard output";
        return 1;
    }

    return app.exec();
}
