Example analysis of simple network program in go language

This paper analyzes the go language simple network program. Share with you for your reference. The specific analysis is as follows:

The server code is as follows:

package main

import (

    "net"

    "os"

)

func serve(s net.Conn) {

    var buf [1024]byte

    for {

        n, err := s.Read(&buf)

        if err != nil || n == 0 {

            break;

        }

        s.Write(buf[0:n])

    }

}

func main() {

    l, e := net.Listen("tcp", ":12345")

    if e != nil {

        os.Exit(-1)

    }

    for {

        s, e := l.Accept()

        if e != nil {

            os.Exit(-1)

        }

        go serve(s)

    }

}

The client code is as follows:

package main

import (

    "net"

    "os"

)

func main() {

    s, err := net.Dial("tcp", "", "192.168.1.168:12345")

    if err != nil {

        os.Exit(-1)

    }

    for {

        var buf [1024]byte

        n, err := os.Stdin.Read(&buf)

        if err != nil || n == 0 {

            os.Exit(-1)

        }

        s.Write(buf[0:n])

        n, err = s.Read(&buf)

        if err != nil || n == 0 {

            os.Exit(-1)

        }

        os.Stdin.Write(buf[0:n])

    }

}

I hope this article has been helpful to you in the programming of Go language.
