qt 遇到发送的字符串为BGK格式的解析方法

            QString sendModeMessage = "";
            //sendModeMessage = QString(QByteArray(pt.sendModeMessage).toHex()).toUpper();//3078303020B4A5B7A2C9CFB1A8
            QTextCodec *code=QTextCodec::codecForName("GBK");
            QTextDecoder *decode = code->makeDecoder();
            sendModeMessage = decode->toUnicode(pt.sendModeMessage);

　　　　　　　//结果为　　0x00 触发上报
