go语言socket服务器端和客户端简单实现

package main

import (
    "bufio"
    "fmt"
    "log"
    "net"
)

func handleConnection(conn net.Conn) {
    defer conn.Close()
    data, err := bufio.NewReader(conn).ReadString(‘\n‘)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(string(data))
    fmt.Fprintf(conn, "who?\n")
    data, err = bufio.NewReader(conn).ReadString(‘\n‘)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(string(data))
}

func main() {
    l, err := net.Listen("tcp", ":2300")
