Aby zmodyfikować pozostały prefiks adresu URL, możesz filtrować rest_url_prefix. Ale to tylko zmienia /wp-json/ przedrostek, którego używa każda przestrzeń nazw.

Próbuje modyfikować wp/v2 oznacza modyfikację wtyczki, a przestrzeń nazw jest zakodowana na stałe w kilku miejscach, takich jak; WP_REST_Post_Statuses_Controller.

Aby dodać własne niestandardowe punkty końcowe, register_rest_route jest w rdzeniu, aby to zrobić.

<?php
add_action( 'rest_api_init', function () {
    register_rest_route( 'your-namespace-here/v1', '/author/(?P<id>\d+)', array(
        'methods' => 'GET',
        'callback' => 'my_awesome_func',
    ) );
} );

Musisz dokładniej przyjrzeć się procesowi wykrywania, aby zobaczyć, co jest automatycznie budowane dla twojego interfejsu API.

Przykład wzorca kontrolera dla wtyczki WP REST API powinien dać ci dobre wyobrażenie o tym, co może wejść do kontrolera WP REST.

Dwie główne rzeczy, które wystają, to:

'args' => $this->get_endpoint_args_for_item_schema( WP_REST_Server::EDITABLE )

I

'args'     => array (
    'force' => array (
        'default' => false,
    ),
),

Kolejny przykład przejścia $args Do register_rest_route który pojawiłby się w katalogu głównym przestrzeni nazw:

register_rest_route( "{$root}/{$version}", '/products', array(
        array(
            'methods'         => \WP_REST_Server::READABLE,
            'callback'        => array( $cb_class, 'get_items' ),
            'args'            => array(
                'per_page' => array(
                    'default' => 10,
                    'sanitize_callback' => 'absint',
                ),
                'page' => array(
                    'default' => 1,
                    'sanitize_callback' => 'absint',
                ),
                'soon' => array(
                    'default' => 0,
                    'sanitize_callback' => 'absint',
                ),
                'slug' => array(
                    'default' => false,
                    'sanitize_callback' => 'sanitize_title',
                )

            ),

            'permission_callback' => array( $this, 'permissions_check' )
        ),
    )

);

Patrząc nieco dalej, get_data_for_route jest używany do zbierania tego, co kończy się w punktach końcowych wykrywania i można go filtrować rest_endpoints_description Lub get_data_for_route. Tak więc teoretycznie, jeśli ustawienie domyślne nie daje tego, czego chcesz, możesz użyć tego filtra, aby dodać swoje modele i/lub kolekcje do swojego prywatnego interfejsu API.

Więc składając to wszystko razem i zastępując automatyczne punkty końcowe:

function my_awesome_func( WP_REST_Request $request) {
    return "awesome! " . $request->get_param( 'id' );
}

add_action( 'rest_api_init', function() {
    register_rest_route( 'my-thing/v1', '/awesome/(?P<id>\d+)', array (
        'methods'  => 'GET',
        'callback' => 'my_awesome_func',
    ) );
} );

add_filter( 'rest_endpoints_description', function( $data ) {

    if ( $data[ 'namespace' ] === 'my-thing/v1' ) {

        $data[ 'endpoints' ] = array (
            'foo'     => 'bar',
            'my'      => 'custom-api',
            'awesome' => 'it really is',
        );
    }

    return $data;
} );
