unsigned char* 类型数据转换字符串 string

如下方法//const unsigned short *p = (const unsigned short *)apBulkBuf;//const WORD *p = (const WORD *)apBulkBuf;if (*(unsigned short *)apBulkBuf == kSynWordDeviceInfoValue)//if (*p == kSynWordDeviceInfoValue){// TODO:// 1//QString qstrContent; //unsigned char* uszContent = (unsigned char *)qstrContent.toUtf8().data(); QString qstrContent = QString::fromUtf8(QByteArray((char*)apBulkBuf));// 2std::string str = std::string((const char *)apBulkBuf);// 3QString str4 = QString::fromLocal8Bit((const char *)apBulkBuf, aNBufSize);//QByteArray byteArrayTempInfo;//byteArrayTempInfo.toHex();// 4std::string str2(apBulkBuf, apBulkBuf + aNBufSize);// 5QString str3 = (char*)apBulkBuf;// 6char* strTemp = new char[aNBufSize];memcpy(strTemp, apBulkBuf, aNBufSize);std::string str6 = strTemp;// 7QString str7 = QString(QLatin1String((char*)apBulkBuf));// 写文件std::ofstream out("\\temp\\out.txt");if (out.is_open()){out << "1.
