QString和string互相转换乱码处理

转化与乱码处理

std::string cstr;
QString qstring;
//从std::string 到QString
qstring = QString(QString::fromLocal8Bit(cstr.c_str()));
//从QString 到 std::string
cstr = string((const char *)qstring.toLocal8Bit());
//不需要从gbk转到utf8
QString value_content = QString::fromStdString(vec[i].content);
QString value_classname = QString::fromStdString(vec[i].classname);
