【提问】求救！数据的处理问题 [复制链接]

char dbuf[] = "测试字符串";
char* tpstr = dbuf;

QString csdata = QString::fromLocal8Bit( (char*)tpstr, -1 ); //显示csdata正确
unsigned char* pstr = (unsigned char*)csdata.data();//取数据的指针
sedes( (unsigned char*)pstr, strlen( (char*)pstr ) );//加密
sedes( (unsigned char*)pstr, strlen((char*)pstr) );//解密
QString mmn = QString::fromLocal8Bit( (char*)pstr, -1 ); //显示mmn数据错误，去掉加、解密过程也一样显示错误的据数，初步怀疑是错误是出在:
unsigned char* pstr = (unsigned char*)csdata.data();
这一行上，可是不知道什么改？
如果把这一行数据改为:
unsigned char* pstr = (unsigned char*)csdata.unicode():会显示不同的错误数据


请大侠帮帮忙，谢谢！

出来的数据还是不正确

谢谢！我试试

看看下面的可否，注意红色部分

char dbuf[] = "测试字符串";
char* tpstr = dbuf;
QString csdata = QString::fromLocal8Bit( (char*)tpstr, -1 ); //显示csdata正确
unsigned char* pstr = (unsigned char*)csdata.toLocal8Bit.data();//取数据的指针
sedes( (unsigned char*)pstr, strlen( (char*)pstr ) );//加密
sedes( (unsigned char*)pstr, strlen((char*)pstr) );//解密
QString mmn = QString::fromLocal8Bit( (char*)pstr, -1 ); //显示mmn数据错误，去掉加、解密过程也一样显
