go语言实现一个简易rpc远程调用的服务端和客户端

服务端代码

package main

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

type HelloService struct { //空结构体

}

func (p *HelloService) Hello(request string, reply *string) error { //为hello结构体绑定hello方法
	*reply = "你好:" + request //拼接字符串
	return nil               //返回空值

}

func main() {
	rpc.RegisterName("HelloService", new(HelloService))
	listener, err := net.Listen("tcp", "localhost:1234")
	if err != nil {
		log.Fatal("ListenTCP erro :", err)

	}

	conn, err := listener.Accept()
	if err != nil {
		log.Fatal("Accept error:", err)
	}
	rpc.ServeConn(conn)
}

客户端代码

package main

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

func main() {
	client, err := rpc.Dial("tcp", "localhost:1234")
	if err != nil {
		log.Fatal("dialing : ", err)
	}
	var reply string
	err = client.Call("HelloService.Hello", "hello", &reply)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(reply)
}

返回结果

你好:hello
