Microsoft OneDrive API client in Perl can't get access token

Question

I created this simple code in Perl to connect Microsoft OneDrive API and list files and folders. But now I'm stopped on getting access token.

I read the Microsoft's documentation to find out, but I nothing found.

Here is the code:

#!/usr/bin/perl -w
use strict;
use LWP; use LWP::UserAgent;

my $client_id = '...';
my $client_secret = '...';
my $client_agent = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.104 Safari/537.36'; # whatever
my $ua = new LWP::UserAgent;
$ua->->show_progress(1);  # Microsoft use url redirection and I want to see the steps
$ua->agent($client_agent);
$ua->timeout(30);
my $URL = 'https://login.live.com/oauth20_desktop.srf'; # from documentation
my @params = (
    "client_id=".$client_id,
    "scope=onedrive.readonly",
    "response_type=token",
    "redirect_uri=https://login.live.com/oauth20_desktop.srf"
);
my $URLFULL = $URL."?".join("&", @params);
my $res = $ua->get($URLFULL);
if ( $res->is_success ) {
    print $res->request->uri->as_string."\n"; # it should be the url with a valid token
    my $block = $res->as_string;
    print $block; # this is the full response
} else {
    die ($res->as_string."error in loading page");
}

So I send a GET message to the URL and it should be redirect to the URL what contain the access token. But I redirected to the same URL what I called.

How can I get the access token? Or where is the mistake in my code? Or is there any working example?

In the documentation, it says that the URL with the params should be like:

GET https://login.live.com/oauth20_authorize.srf?client_id={client_id}&scope={scope}&response_type=token&redirect_uri={redirect_uri} 

Your $URL parameter seems wrong. $URL should be https://login.live.com/oauth20_authorize.srf and redirect URL is https://login.live.com/oauth20_desktop.srf.

I didn't try the code since I don't want to create and MS account just for this ;)
