Golang RPC Server/Client example

readme.md

Build executable files using this commands:

GOOS=your_system go build server.go

GOOS=your_system go build client.go

Upload server file to remote server and run with ./server

On client machine run client file with second argument(server ip address) like this ./client 35.204.248.15 and type text which will be printed on server

client.go

package main

import (
	"bufio"
	"log"
	"net/rpc"
	"os"
)

func main() {
	client, err := rpc.Dial("tcp", os.Args[1]+":80")
	if err != nil {
		log.Fatal(err)
	}
	println("Type your text")
	in := bufio.NewReader(os.Stdin)
	for {
		line, _, err := in.ReadLine()
		if err != nil {
			log.Fatal(err)
		}
		var reply bool
		err = client.Call("L.G", line, &reply)
		if err != nil {
			log.Fatal(err)
		}
	}
}

server.go

package main

import (
	"fmt"
	"log"
	"net"
	"net/rpc"
)

type L int

func (l *L) G(line []byte, res *bool) error {
	fmt.Println(string(line))
	return nil
}

func main() {
	addy, err := net.ResolveTCPAddr("tcp", "0.0.0.0:80")
	if err != nil {
		log.Fatal(err)
	}
	inb, err := net.ListenTCP("tcp", addy)
	if err != nil {
		log.Fatal(err)
	}
	rpc.Register(new(L))
	rpc.Accept(inb)
}
