Go で失敗した HTTP リクエストを再試行するにはどうすればよいですか?

<code class="go">package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "net/http"
    "time"
)

func main() {
    var (
        err      error
        response *http.Response
        retries  int = 3
    )
    for retries > 0 {
        response, err = http.Get("https://non-existent")
        // Change the URL to "https://google.com/robots.txt" for testing
        if err != nil {
            log.Println(err)
            time.Sleep(2 * time.Second) // Introduce a delay between retries
            retries -= 1
            continue
        } else {
            break
        }
    }

    if response != nil {
        defer response.Body.Close()
        data, err := ioutil.ReadAll(response.Body)
        if err != nil {
            log.Fatal(err)
        }
        fmt.Printf("data = %s\n", data)
    }
}</code>
