How to do url encode of json in ruby

Question

I want to encode a recipients json using ruby method, Below is the sample code,

recipients = 
{
"1JzSZFs2DQke2B3S4pBxaNaMzzVZaG4Cqh": 100000000,
"12Cf6nCcRtKERh9cQm3Z29c9MWvQuFSxvT": 1500000000,
"1dice6YgEVBf88erBFra9BHf6ZMoyvG88": 200000000
}

Example url formation in php,

<?

$guid="GUID_HERE";
$firstpassword="PASSWORD_HERE";
$secondpassword="PASSWORD_HERE";
$amounta = "10000000";
$amountb = "400000";
$addressa = "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq";
$addressb = "1ExD2je6UNxL5oSu6iPUhn9Ta7UrN8bjBy";
$recipients = urlencode('{
              "'.$addressa.'": '.$amounta.',
              "'.$addressb.'": '.$amountb.'
           }');

$json_url = "http://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients";

how to do this urlencode using ruby?

Answer 1

Use URI.escape

require 'uri'

enc_uri = URI.escape("http://example.com/?a=\11\15")
p enc_uri
# => "http://example.com/?a=%09%0D"

Answer 2

require 'uri'

enc_uri = URI.encode_base64("http://example.com/?a=\11\15")

p enc_uri
