messagepack 初试

本来想玩protocbuf的可是3.0版本的弄了一个早上，在window上都无法编译，就试玩了下messagepack。

messagepack直接下源码用vs编译，一次通过。下面直接贴上例子。

// msgPack.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include <msgpack.hpp>
#include <vector>
#include <string>
#include <iostream>

class myclass {
public:
std::string m_str;
std::vector<int> m_vec;

public :
myclass()
{

}
myclass(std::string str, std::vector<int> v) {
m_str = str;
m_vec = v;
}
public:
MSGPACK_DEFINE(m_str, m_vec);
};

int main(void) {
msgpack::sbuffer buffer;

msgpack::packer<msgpack::sbuffer> pk(&buffer);
pk.pack_array(3);
pk.pack(std::string("Log message ... 1"));
pk.pack(std::string("Log message ... 2"));
pk.pack(std::string("Log message ... 3"));

msgpack::unpacked msg;
msgpack::unpack(&msg, buffer.data(), buffer.size());

msgpack::object obj = msg.get();

std::vector<std::string> v;
obj.convert(v);

for (auto it = v.begin(); it < v.end(); ++it)
{
std::cout << *it << std::endl;
}

// serializes multiple objects into one message containing a map using msgpack::packer.
msgpack::sbuffer buffer2;

msgpack::packer<msgpack::sbuffer> pk2(&buffer2);
pk2.pack_map(2);
pk2.pack(std::string("x"));
pk2.pack(3);
pk2.pack(std::string("y"));
pk2.pack(4);

msgpack::unpacked msg1;
msgpack::unpack(&msg1, buffer2.data(), buffer2.size());

msgpack::object obj2 = msg1.get();

std::map<std::string,int> m;
obj2.convert(m);

for (auto it = m.begin(); it != m.end(); ++it)
{
std::cout << it->first;
}
system("pause");
}
