qt 序列化和反序列化

     序列化：
     QByteArray buffer;

    QBuffer bufferDevice(&buffer);

    bufferDevice.open(QIODevice::WriteOnly);

    QDataStream out(&bufferDevice);

    out.setVersion(QDataStream::Qt_5_13);

反序列化：

 void deserialize(const QByteArray &buffer) {

        QBuffer bufferDevice(const_cast<QByteArray*>(&buffer));

        bufferDevice.open(QIODevice::ReadOnly);

        QDataStream in(&bufferDevice);

        in.setVersion(QDataStream::Qt_5_13);

        in >>frameHeader >> packetSeq >> dataLength >> batteryLevel >> channelCount

           >> pitchAngle >> rollAngle >> yawAngle >> ecg >> spo2

           >> reserved1 >> reserved2 >> reserved3 >> reserved4;

        dataBlock.resize(dataLength);

        in.readRawData(dataBlock.data(), dataLength);
