pass variable through url in wordpress - php

Question

I have wordpress custom template page test.php in which I want to pass variable throuh url like,
http://localhost/wordpress/test?date=2017&postid=11&title=some-title
in this format,
http://localhost/wordpress/test/2017/11/some-title
and grab the parameter from the url.
I have followed this link, but couldn't produce the result as I have desired.
Is there another way to achieve the desired result as I have mentioned??? I am pretty newbie to wordpress theme development.

Well, as suggested by #vl4d1m1r4 , I have used the web server(in my case apache) rewrite rule to rewrite the path. Some-what I have achieved the desired result.
In function.php
I have written the following code to update the rewrite rule in wordpress(.htaccess)
add_filter( 'query_vars', 'add_custom_query_vars' );
function add_custom_query_vars( $vars )
{
array_push($vars, "test_year", "test_postid", "test_title");
return $vars;
}
function custom_rewrite_rule()
{
add_rewrite_rule('^test/([^/]*)/([^/]*)/([^/]*)?','index.php?pagename=test&test_year=$matches[1]&test_postid=$matches[2]&test_title=$matches[3]','top');
}
add_action('init', 'custom_rewrite_rule');
After adding the above code, I have re-saved the permalink settings(setting>>permalink)
To Get the parameter in custom-template-page i.e test.php. I have used the following query.
echo get_query_var('test_title');
echo get_query_var('test_postid');
echo get_query_var('test_year');
