GitHub - gamark/msgpack-rpc-cpp11: EasyRPC is a msgpack-rpc + α implementation for Modern C++17 language.built on top of https://github.com/rpclib/rpclib

中文版

EasyRPC is a RPC library for C++, providing both a client and server implementation. It is built using modern C++14, and as such, requires a recent compiler. Main highlights:

  • Expose functions of your program to be called via RPC (from any language implementing msgpack-rpc)
  • Call functions through RPC (of programs written in any language)
  • No IDL to learn
  • No code generation step to integrate in your build, just C++
  • Support auto-reconnect
  • Support msgpack-c 3.1(include cpp17)
  • Support customize dispatcher.

Look&feel

Server

#include <iostream>
#include "rpc/server.h"

void foo() {
    std::cout << "foo was called!" << std::endl;
}

int main(int argc, char *argv[]) {
    // Creating a server that listens on port 8080
    rpc::server srv(8080);

    // Binding the name "foo" to free function foo.
    // note: the signature is automatically captured
    srv.bind("foo", &foo);

    // Binding a lambda function to the name "add".
    srv.bind("add", [](int a, int b) {
        return a + b;
    });

    // Run the server loop.
    srv.run();

    return 0;
}

When srv.run() is called, EasyRPC starts the server loop which listens to incoming connections and tries to dispatch calls to the bound functions. The functions are called from the thread where run was called from. There is also async_run that spawns worker threads and returns immediately.

Client

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

int main() {
    // Creating a client that connects to the localhost on port 8080
    rpc::client client("127.0.0.1", 8080);

    // Calling a function with paramters and converting the result to int
    auto result = client.call("add", 2, 3);
    std::cout << "The result is: " << result << std::endl;
    return 0;
}

Status

All planned 1.0.0 features are done and tested; the current state is production-ready.
