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") {
msgpack::type::tuple<int, int> params;
req.params().convert(¶ms);
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.
