How to perform HTTP basic authentication in Go client requests?

In Go, you can perform HTTP basic authentication in client requests by setting the Authorization header with the encoded username and password. Here's an example:

package main

import (
	"fmt"
	"net/http"
	"encoding/base64"
)

func main() {
	// Create a new HTTP client
	client := &http.Client{}

	// Create a new request
	req, err := http.NewRequest("GET", "https://api.example.com/endpoint", nil)
	if err != nil {
		fmt.Println("Error creating request:", err)
		return
	}

	// Set the Authorization header
	username := "your_username"
	password := "your_password"
	auth := username + ":" + password
	basicAuth := "Basic " + base64.StdEncoding.EncodeToString([]byte(auth))
	req.Header.Set("Authorization", basicAuth)

	// Send the request
	resp, err := client.Do(req)
	if err != nil {
		fmt.Println("Error sending request:", err)
		return
	}
	defer resp.Body.Close()

	// Process the response
	fmt.Println("Response status:", resp.Status)
	// ...
}

Replace "your_username" and "your_password" with your actual credentials.
