wordpress Custom url parameters to implement the routing function code example

After two days of regular expression learning and wordpress routing function research, we have successfully implemented the custom wordpress routing function. The following is the implementation of the routing rules.
If you have a custom url parameter, to pass through the route, you must add it to the wordpress function:

//add query_args
function add_query_vars($aVars) {
    $aVars[] = 'score';
    $aVars[] = 'type'; // represents the name of the product category as shown in the URL
    return $aVars;
}
add_filter('query_vars', 'add_query_vars');//wordpress The filter 

At the same time, wordpress's function is also used to get the parameters on the page:

$type=isset($wp_query->query_vars['type'])?urldecode($wp_query->query_vars['type']):'';

// Routing rules - Sort by time and the most recent entries by category 
function add_rewrite_rules($aRules) {
    $aNewRules = array(
        'text/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$' => 'index.php?cat=2&score=$matches[1]&paged=$matches[3]',
        'image/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=3&score=$matches[1]&paged=$matches[3]',
        'video/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=4&score=$matches[1]&paged=$matches[3]',
        'resource/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=5&score=$matches[1]&paged=$matches[3]',
        'text/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=2&type=$matches[1]&paged=$matches[3]',
        'image/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=3&type=$matches[1]&paged=$matches[3]',
        'video/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=4&type=$matches[1]&paged=$matches[3]',
        'resource/(latest)/?$'=>'index.php?cat=5&type=$matches[1]',
        '(month)/?(/page/([0-9]+)?)?/?$'=>'index.php?score=$matches[1]&paged=$matches[3]',
        '(24hr)/?(/page/([0-9]+)?)?/?$'=>'index.php?score=$matches[1]&paged=$matches[3]',
    );
    $aRules = $aNewRules + $aRules;
    return $aRules;
}
add_filter('rewrite_rules_array', 'add_rewrite_rules');

// Routing rules - category 
add_rewrite_rule('^text/?(/page/([0-9]+)?)?/?$','index.php?cat=2&paged=$matches[2]','top'); // Corresponding category ID
add_rewrite_rule('^image/?(/page/([0-9]+)?)?/?$','index.php?cat=3&paged=$matches[2]','top');
add_rewrite_rule('^video/?(/page/([0-9]+)?)?/?$','index.php?cat=4&paged=$matches[2]','top'); 
add_rewrite_rule('^resource/?(/page/([0-9]+)?)?/?$','index.php?cat=5&paged=$matches[2]','top');
