如何序列化对象以通过网络发送 [英] How to serialize an object to send over network

问题描述

我正在尝试序列化对象，以仅使用STL通过套接字通过网络发送.我没有找到一种方法来保持对象结构在其他主机中反序列化.我尝试转换为 string ，转换为 char * ，并且花了很长时间在互联网上搜索教程，直到现在我仍然一无所获.

I'm trying to serialize objects to send over network through a socket using only STL. I'm not finding a way to keep objects' structure to be deserialized in the other host. I tried converting to string, to char* and I've spent a long time searching for tutorials on the internet and until now I have found nothing.

是否只有STL可以做到?

Is there a way to do it only with STL?

有什么好的教程吗?

我几乎要尝试增强功能，但是如果有使用STL的方法，我想学习.

I am almost trying boost, but if there is how to do it with STL I'd like to learn.

推荐答案

我明白了！

我使用strinstream序列化对象，并使用stringstream的str()方法和字符串的c_str()将其作为消息发送.

I used strinstream to serialize objects and I sent it as a message using the stringstream's method str() and so string's c_str().

看.

class Object {
public:
int a;
string b;

void methodSample1 ();
void methosSample2 ();

friend ostream& operator<< (ostream& out, Object& object) {
out << object.a << " " << object.b;   //The space (" ") is necessari for separete elements
return out;
}

friend istream& operator>> (istream& in, Object& object) {
in >> object.a;
in >> object.b;
return in;
}
};

/* Server side */
int main () {
Object o;
stringstream ss;
o.a = 1;
o.b = 2;
ss << o;    //serialize

write (socket, ss.str().c_str(), 20); //send - the buffer size must be adjusted, it's a sample
}

/* Client side */
int main () {
Object o2;
stringstream ss2;
char buffer[20];
string temp;

read (socket, buffer, 20);  //receive
temp.assign(buffer);
ss << temp;
ss >> o2;   //unserialize
}

我不确定在序列化之前是否有必要转换为字符串(ss< o)，也许可以直接从char中获得.

I'm not sure if is necessary convert to string before to serialize (ss << o), maybe is possible directly from char.
