MessagePack-RPC for C++

Requirements

Following programs are requred to build:

gcc >= 4.1 with C++ support
MessagePack for C++ >= 0.5.2
boost::asio for communucation and a loop processing.

Installation

Configure and install in the usual way:

$ cmake .
$ make
$ sudo make install

Usage

Test cases will give you a sample usage.

Example

Simple client

#include <msgpack/rpc/client.h>
#include <iostream>

int main(void)
{
	msgpack::rpc::client c("127.0.0.1", 9090);
	int result = c.call("add", 1, 2).get<int>();
	std::cout << result << std::endl;
}

Simple server

#include <msgpack/rpc/server.h>

class myserver : public msgpack::rpc::server::base {
public:
	void add(msgpack::rpc::request req, int a1, int a2)
	{
		req.result(a1 + a2);
	}

public:
	void dispatch(msgpack::rpc::request req)
	try {
		std::string method;
		req.method().convert(&method);

		if(method == "add") {
                   std::tuple<int, int> params;
			req.params().convert(&params);
			add(req, params.get<0>(), params.get<1>());

		} else {
			req.error(msgpack::rpc::NO_METHOD_ERROR);
		}

	} catch (msgpack::type_error& e) {
		req.error(msgpack::rpc::ARGUMENT_ERROR);
		return;

	} catch (std::exception& e) {
		req.error(std::string(e.what()));
		return;
	}
};

int main(void)
{
	myserver svr;
	svr.instance.listen("0.0.0.0", 9090);
	svr.instance.run(4);  // run 4 threads
}

IDL parser and code generator is under development. It will resolve the problem that users have to implement verbose dispatch() function.
