go语言实现unix通讯

service端

package main

import (
	"bufio"
	"fmt"
	"net"
	"time"
)

func main() {
	var addr *net.UnixAddr

	addr, _ = net.ResolveUnixAddr("unix", "/tmp/unix_ss")

	unixListener, _ := net.ListenUnix("unix", addr)

	defer unixListener.Close()

	for {
		conn, err := unixListener.AcceptUnix()
		if err != nil {
			continue
		}

		fmt.Println("A client connected : " + conn.RemoteAddr().String())
		go unixPipe(conn)
	}

}

func unixPipe(conn *net.UnixConn) {
	ipStr := conn.RemoteAddr().String()
	defer func() {
		fmt.Println("disconnected :" + ipStr)
		conn.Close()
	}()
	reader := bufio.NewReader(conn)

	for {
		//读取客户端内容
		message, err := reader.ReadString('\n')
		if err != nil {
			return
		}

		fmt.Println(string(message))
		msg := time.Now().String() + "\n"
		b := []byte(msg)
		//将当前时间写回给客户端
		conn.Write([]byte("service : "))
		conn.Write(b)
	}
}

 

client端 

package main

import (
	"bufio"
	"fmt"
	"net"
	"time"
)

var quitSemaphore chan bool

func main() {
	var addr *net.UnixAddr
	addr, _ = net.ResolveUnixAddr("unix", "/tmp/unix_ss")

	conn, _ := net.DialUnix("unix", nil, addr)
	defer conn.Close()
	fmt.Println("connected!")

	go onMessageRecived(conn)

	b := []byte("time\n")
	conn.Write([]byte("client: "))
	conn.Write(b)

	<-quitSemaphore
}

func onMessageRecived(conn *net.UnixConn) {
	reader := bufio.NewReader(conn)
	for {
		msg, err := reader.ReadString('\n')
		fmt.Println(msg)
		if err != nil {
			quitSemaphore <- true
			break
		}
		time.Sleep(time.Second)
		b := []byte(msg)
		conn.Write([]byte("client: "))
		conn.Write(b)
	}
}
