How to Determine the Final URL After Redirections in Go?

Retrieving Final URL after Redirections in Go

In Go's net/http package, with automatic redirection handling, numerous URLs often result in a specific terminal URL. Determining the final URL after a sequence of redirections can be a challenge.

One possible solution without employing a hackish workaround lies in examining the Request component of the Response object. The Request object corresponds to the ultimate URL accessed by the client.

package main

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

func main() {
    resp, err := http.Get("http://stackoverflow.com/q/16784419/727643")
    if err != nil {
        log.Fatalf("http.Get => %v", err.Error())
    }

    finalURL := resp.Request.URL.String()

    fmt.Printf("The URL you ended up at is: %v\n", finalURL)
}

This code retrieves the final URL after possible redirections and prints it using the Request.URL.String() method.

Output:

The URL you ended up at is: http://stackoverflow.com/questions/16784419/in-golang-how-to-determine-the-final-url-after-a-series-of-redirects
