post HTTP query via HTTParty

i want to use mailerlite API to add subscribers to a list

here is what APIdoc says to generate request

$subscriber = array(
    'email' => '[email protected]',
    'name' => 'foo',
    'fields' => array( 
       array( 'name' => 'country', 'value' => "usa" )
    )
);
$subscriber = $ML_Subscribers->setId( LIST_ID )->add( $subscriber );

and it generates a query string like this

email=foo%40bar.com&name=foo&fields%5B0%5D%5Bname%5D=country&fields%5B0%5D%5Bvalue%5D=usa

and sends it to mailerlite server my question is how to generate string via ruby HTTParty gem or rails methods

Solution

for generating exact same result as php code you should use this gem https://rubygems.org/gems/php_http_build_query

example of use

puts PHP.http_build_query({"a"=>"b","c"=>"d","e"=>[{"hello"=>"world","bah"=>"black"},{"hello"=>"world","bah"=>"black"}]})

#a=b&c=d&e%5B0%5D%5Bbah%5D=black&e%5B0%5D%5Bhello%5D=world&e%5B1%5D%5Bbah%5D=black&e%5B1%5D%5Bhello%5D=world
