将代码从PHP转换为Ruby on Rails

I'm trying to use geoip's web service for a ruby on rails application. They don't give any ruby demos but this is what they give for PHP. I was wondering if anyone knew how to convert this to work on ruby on rails? I only need the city and the region from the data. More examples can be found at their site at

$query = "http://geoip3.maxmind.com/b?l=" . $license_key . "&i=" . $ipaddress;
$url = parse_url($query);
$host = $url["host"];
$path = $url["path"] . "?" . $url["query"];
$timeout = 1;
$fp = fsockopen ($host, 80, $errno, $errstr, $timeout)
or die('Can not open connection to server.');
if ($fp) {
  fputs ($fp, "GET $path HTTP/1.0
Host: " . $host . "

");
  while (!feof($fp)) {
    $buf .= fgets($fp, 128);
  }
  $lines = split("
", $buf);
  $data = $lines[count($lines)-1];
  fclose($fp);
} else {
  # enter error handing code here
}

echo $data;
$geo = explode(",",$data);
$country = $geo[0];
$state = $geo[1];
$city = $geo[2];
$lat = $geo[3];
$lon = $geo[4];
