QDataStream 传递自定义的结构

QT自带的QDataStream只能传递它自己要求的数据类型。但是我们可以自己重载QDataStream& operator<<()和QDataStream& operator>>();

mydatastream.h

 1 #ifndef MYDATASTREAM_H
 2 #define MYDATASTREAM_H
 3 
 4 #include <QDataStream>
 5 
 6     struct UserInfor{
 7         QString id;
 8         QString state;
 9         QString ip;
10         QString port;
11         QString nickName;
12         QByteArray headPhoto;
13         QString discription;
14     };
15 
16     inline QDataStream& operator<<(QDataStream& out, const UserInfor& userInfor)
17     {
18         out<<userInfor.id<<userInfor.state<<userInfor.ip<<userInfor.port<<
19              userInfor.nickName<<userInfor.headPhoto<<userInfor.discription;
20         return out;
21     }
22 
23     inline QDataStream& operator>>(QDataStream& in,UserInfor& userInfor)
24     {
25         in>>userInfor.id>>userInfor.state>>userInfor.ip>>userInfor.port>>userInfor.nickName
26             >>userInfor.headPhoto>>userInfor.discription;
27        return in;
28     }
29 
30 #endif // MYDATASTREAM_H
