使用Boost序列化和发送数据结构? [英] Serialize and send a data structure using Boost?

问题描述

我有一个如下所示的数据结构:

<前>类型定义结构{无符号短 m_short1;无符号短 m_short2;无符号字符 m_character;我的数据类型；

我想使用 boost::serialization 来序列化这个数据结构，然后使用 boost::asio 通过 TCP/IP 传输它，然后让另一个应用程序接收数据并使用相同的 boost 库反序列化它.

我正在尝试关注 boost::serialization教程，(正如其他一些 SO 问题所建议的那样) 但该示例专门用于写入/读取文件，而不是使用 boost::asio 的套接字.

我很确定我有适合这项工作的工具——我只是需要帮助让它们协同工作.写入套接字与写入文件不会有什么不同，对吗?

非常感谢任何建议.谢谢！

解决方案

对于如此简单的结构，boost::serialization 是矫枉过正，开销巨大.

做得更简单:

vector净(3,0)；net[0]=htons(data.m_short1);net[1]=htons(data.m_short2);net[2]=htons(data.character);asio::async_write(socket,buffer((char*)&net.front(),6),callback);向量净(3,0)；asio::async_read(socket,buffer((char*)&net.front(),6),callback);打回来:data.m_short1=ntohs(net[0]);data.m_short2=ntohs(net[1]);data.character=ntohs(net[2]);

并为自己节省 boost::serialization 带来的巨大开销

如果您使用具有相同字节顺序的计算机工作的私有协议(大/小)只是按原样发送结构——POD.

I have a data structure that looks like this:

typedef struct
{
  unsigned short m_short1;
  unsigned short m_short2;
  unsigned char m_character;
} MyDataType;

I want to use boost::serialization to serialize this data structure, then use boost::asio to transmit it via TCP/IP, then have another application receive the data and de-serialize it using the same boost libraries.

I'm trying to following boost::serialization tutorial, (as some other SO questions have suggested) but the example is specifically for writing/reading to a file, not to a socket using boost::asio.

I'm pretty sure I've got the right tools for the job -- I just need help making them work together. Writing to a socket can't be that different from writing to a file, right?

Any suggestions are very much appreciated. Thanks!

解决方案

For such simple structure, boost::serialization is overkill and huge overhead.

Do simpler:

vector<uint16_t> net(3,0);

net[0]=htons(data.m_short1);
net[1]=htons(data.m_short2);
net[2]=htons(data.character);

asio::async_write(socket,buffer((char*)&net.front(),6),callback);

vector<uint16_t> net(3,0);
asio::async_read(socket,buffer((char*)&net.front(),6),callback);

callback:
data.m_short1=ntohs(net[0]);
data.m_short2=ntohs(net[1]);
data.character=ntohs(net[2]);

And Save yourself HUGE overhead that boost::serialization has

And if you private protocol where computers with same order of bytes work (big/little) that just send structure as is -- POD.
