Developing a TCP Client

Developing a TCP Client

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

We'll cover the following...

Developing a TCP client with net.Dial()

First, we are going to present the most widely used way, which is implemented in tcpC.go:

Go (1.19.0)
package main
import (
	"bufio"
	"fmt"
	"net"
	"os"
	"strings"
)

The import block contains packages such as bufio and fmt that also work with file I/O operations.

Go (1.19.0)
func main() {
	arguments := os.Args
	if len(arguments) == 1 {
		fmt.Println("Please provide host:port.")
		return
	}

First, we read the details of the TCP server we want to connect to.

Go (1.19.0)
	connect := arguments[1]
	c, err := net.Dial("tcp", connect)
	if err != nil {
		fmt.Println(err)
		return
	}
