C ++中的网络协议对象序列化 [英] Network protocol object serialization in C++

问题描述

我正在编写一些C ++代码，这些代码必须通过TCP / IP发送数据。我希望此代码在Linux / Windows / Osx上可移植。现在，因为这是我第一次编写可移植的网络代码，所以我基本上需要一些简单的函数来添加某些对象，例如：

I'm writing some C++ code that will have to send data over TCP/IP. I want this code to be portable on Linux/Windows/Osx. Now, as it is the first time I write portable network code, I basically need some simple functions to add to certain objects like:

class myclass{

...member...

public:

  string serialize(){
    std::ostringstream out();
    out << member1;
    out << member2;
    out << member3;
    return out.str();
  }

}

...这就是我现在需要。无论如何，我开始阅读与ostringstream相关的文档，并发现了二进制/文本问题。实际上，它将换行符转换为每个系统的正确顺序。例如，假设成员是指向const char * foo = Hello\nMan\n的指针，那么它将在linux上以某些字节顺序转换，在Windows上以另一个字节顺序转换，依此类推。我的字节将通过互联网发送到一个数据包中，另一台OS机器将读取它们，并且我认为会发生麻烦...现在，我读到我可以用<初始化 ostringstream code> ostringstream（ios :: bin） ...是否可以解决问题（前提是我将使用反序列化函数，该函数将使用 istringstream（ ios :: bin） ???我对整个图片感到困惑，如果您花一些澄清的行将不胜感激。

... which is all I need for now. Anyway I started reading ostringstream related docs and turns out the binary/text problem. In fact it will convert line breaks to the right sequence of everysystem. Suppose for example that a member is a pointer to const char* foo = "Hello\nMan\n", that will be translated in certain byte sequence on linux, another on windows... and so on. My bytes will go on a packet over the internet, a different OS machine will read them and I think trouble will occurr... Now I read that I might initialize ostringstream with ostringstream(ios::bin)... Will it solve the problem (provided that I will use a de-serialization function that will use a istringstream(ios::bin)??? I'm confused about the whole picture, if you may spend a few clarifying lines that'll be much appreciated.

谢谢。

推荐答案

如果有像可以构建的Boost.Serialization ？

从目标出发：

数据可移植性-在一个平台上创建的字节流应可在任何其他平台上读取。

Data Portability - Streams of bytes created on one platform should be readable on any other.

您也可能感兴趣的点4和5：

Also of interest for you might be points 4 and 5:

• 深层指针的保存和恢复。即，指针的保存和恢复可以保存和恢复指向的数据。


• 正确恢复共享数据的指针。
