Нужна Ruby реализация curl_init() метода эквивалентного на Php

Есть код на Php:

 $timestamp = '1485942173'
 $api_key = '6t7a7c34914c0fa02f34b4b52d55aa2bb2f3b4b7';
 $login = 'admin';
 $phone = '79793665627';
 $return = 'json';
 $sender = 'admin';
 $text = 'Hello!';
$params = array(
   'timestamp' => $timestamp,
   'login'     => $login,
   'phone'     => $phone,
   'text'      => $text,
   'sender'    => $sender,
   'return'    => $return
);
ksort( $params );
reset( $params );
$signature = md5( implode( $params ) . $api_key ); 
$query = "https://test.ru/get/send.php?login=" . $login . "&signature=" . $signature . "&phone=" . $phone . "&sender=" . $sender . "&return=" . $return . "&timestamp=" . $timestamp . "&text=" . urlencode( $text );
$curl = curl_init();
curl_setopt( $curl, CURLOPT_URL, $query );
curl_setopt( $curl, CURLOPT_ENCODING, "utf-8" );
curl_setopt( $curl, CURLOPT_CONNECTTIMEOUT, 120 );
curl_setopt( $curl, CURLOPT_TIMEOUT, 120 );
curl_setopt( $curl, CURLOPT_MAXREDIRS, 10 );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
$result = curl_exec( $curl );

Нужен аналогичный код на Ruby on Rails Я уже пробивал и Net::HTTP и OpenUri и Rest::Client ответ одинаково не правильный в отличие запроса на Php.

Последние что пробивал:

timestamp = '1485942173'
 login = 'admin' 
 sender = 'admin'
 format = 'json'     
 client_phone = '79793665627'
 message = 'Hello!' 
        params = {
            :login => login,
            :phone => client_phone,
            :return => format,
            :sender => sender,
            :text       => message,
            :timestamp  => timestamp }
        api_key = '6t7a7c34914c0fa02f34b4b52d55aa2bb2f3b4b7'
        params_string = params.values.join + api_key
        signature = Digest::MD5.hexdigest(params_string) 
query = "https://test.ru/get/send.php?login=" + login + "&signature=" + signature + "&phone=" + client_phone + "&sender=" + sender + "&timestamp=" + timestamp + "&text=" + CGI.escape(message)
uri = URI(query)
res = Net::HTTP.start(uri.host, uri.port,
                                      :use_ssl => uri.scheme == 'https',
                                      :verify_mode => OpenSSL::SSL::VERIFY_NONE) { |http|
                  request = Net::HTTP::Get.new uri.request_uri
                  response = http.request request
                  resp = JSON.parse(response.body)
  }
