Creating a WebSocket Client

Creating a WebSocket Client

Let’s learn how to create a WebSocket client.

We'll cover the following...

This lesson shows how to program a WebSocket client in Go. The client reads user data that sends it to the server and reads the server response. The client directory of https://github.com/Educative-Content/ws contains the implementation of the WebSocket client—We find it more convenient to include both implementations in the same repository.

As with the WebSocket server, the gorilla/websocket package is going to help us develop the WebSocket client.

Coding example

The code of ./client/client.go is as follows:

Press + to interact
package main
import (
	"bufio"
	"fmt"
	"log"
	"net/url"
	"os"
	"os/signal"
	"syscall"
	"time"
	"github.com/gorilla/websocket"
)
var SERVER = ""
var PATH = ""
var TIMESWAIT = 0
var TIMESWAITMAX = 5
var in = bufio.NewReader(os.Stdin)

The in variable is just a shortcut for bufio.NewReader(os.Stdin).

Press + to interact
func getInput(input chan string) {
	result, err := in.ReadString('\n')
	if err != nil {
		log.Println(err)
		return
	}
	input <- result
}
