Developing a UDP Client

Developing a UDP Client

Let’s learn how to develop a UDP client with Go.

We'll cover the following...

This lesson demonstrates how to develop a UDP client that can interact with UDP services.

Coding example

The code of udpC.go is as follows:

Press + to interact
package main
import (
	"bufio"
	"fmt"
	"net"
	"os"
	"strings"
)
func main() {
	arguments := os.Args
	if len(arguments) == 1 {
		fmt.Println("Please provide a host:port string")
		return
	}
	CONNECT := arguments[1]

This is how we get the UDP server details from the user.

Press + to interact
	s, err := net.ResolveUDPAddr("udp4", CONNECT)
	c, err := net.DialUDP("udp4", nil, s)

The above two lines declare that we are using UDP and that we want to connect to the UDP server that is specified by the return value of net.ResolveUDPAddr(). The actual connection is initiated ...
