Go でリダイレクト後に最終 URL を抽出するにはどうすればよいですか?

package main

import (
    "fmt"
    "log"
    "net/http"
)

func main() {
    // Initiate a GET request for a URL subject to redirects
    resp, err := http.Get("https://google.com") // Replace with the target URL
    if err != nil {
        log.Fatalf("http.Get -> %v", err)
    }

    // Retrieve the final URL using the last attempted Request in the Response
    finalURL := resp.Request.URL.String()

    // Output the resolved final URL
    fmt.Printf("The URL you ended up at is: %s", finalURL)
}
