Golang : How to check if a website is served via HTTPS
Just a short program to check if a website has redirect to HTTPS(SSL) or not. What this program does is to find the final URL of a given URL and then check to see if the final URL has https
or not.
It does not check if the connection is secured with a proper certificate or expired certificate.
Here you go!
package main
import (
"fmt"
"net/http"
"strings"
)
func main() {
// test websites
//originalURL := "//socketloop.com"
//originalURL := "http://geocities.com" -- no https
originalURL := "http://cowner.net" // -- no https
resp, err := http.Get(originalURL)
if err != nil {
fmt.Println(err)
}
// if there is any re-direction happening behind the scene
// the finalURL will be different
// in this case, there will be a re-direction to https (SSL) version
finalURL := resp.Request.URL.String()
fmt.Println("Original URL is : ", originalURL)
fmt.Println("Final URL is : ", finalURL)
// Check if served with https
fmt.Println("Is HTTPS ? : ", strings.HasPrefix(finalURL,"https"))
}
Hope this helps and happy coding!
