我有一个wordpress实例，其中充满了名为“games”的自定义帖子类型。每个游戏都可以有一个等级。frontpage上的主查询使用以下查询：

public function my_modify_main_query( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) { // Run only on the homepage

        $query->set( \'post_type\', array( \'game\', \'post\' ) );

        $query->set( \'tax_query\', array(
            \'relation\' => \'OR\',
            array(
                \'taxonomy\' => \'platform\',
                \'field\'    => \'id\',
                \'terms\'    => array(
                    3, //PS4
                    1312, //PC
                    158, //XBOX ONE
                    10158, //Switch
                ),
                \'operator\' => \'IN\'
            )
        ) );
        $meta_query = array(
            array(
                \'key\'     => \'score_count\',
                \'value\'   => \'0\',
                \'type\'    => \'numeric\',
                \'compare\' => \'>\',
            ),
        );
        $query->set( \'meta_query\', $meta_query );
    }

结果是所有游戏都按发行日期排序。

因为我一直想为这个页面添加一个应用程序，所以我开始使用WP-JSON。首先，在添加了

\'show_in_rest\' => true

到自定义帖子类型的init:/wp json/wp/v2/games

但我无法仅通过使用参数查询相同的复杂结果。

所以我开始编写自己的端点：

function shortscore_register_api_hooks() {
    $namespace = \'shortscore/v1\';

    register_rest_route( $namespace, \'/list-recent-rated-games/\', array(
        \'methods\'  => \'GET\',
        \'callback\' => \'shortscore_get_recent_rated_games\',
    ) );
}
function shortscore_get_recent_rated_games() {
    if ( 0 || false === ( $result = get_transient( \'shortscore_recent_rated_games\' ) ) ) {

        $args = array(
            \'posts_per_page\' => 10,
            \'post_type\'  => \'game\',
            \'tax_query\',
            array(
                \'relation\' => \'OR\',
                array(
                    \'taxonomy\' => \'platform\',
                    \'field\'    => \'id\',
                    \'terms\'    => array(
                        3, //PS4
                        1312, //PC
                        158, //XBOX ONE
                        10158, //Switch
                    ),
                    \'operator\' => \'IN\'
                )
            ),
            \'meta_query\' => array(
                array(
                    \'key\'     => \'score_count\',
                    \'value\'   => \'0\',
                    \'type\'    => \'numeric\',
                    \'compare\' => \'>\',
                ),
            ),
        );

        $query = new WP_Query( $args );

        $rated_games = $query->posts;

        foreach ( $rated_games as $game ) {
            $result[] = array(
                \'ID\'           => $game->ID,
                \'title\'        => $game->post_title,
                \'cover\'        => get_the_post_thumbnail_url( $game->ID, array( 120, 120 ) ),
                \'cover_double\' => get_the_post_thumbnail_url( $game->ID, array( 240, 240 ) ),
                \'permalink\'    => get_permalink( $game->ID ),
                \'score_count\'  => intval( get_post_meta( $game->ID, \'score_count\', true ) ),
                \'score_value\'  => intval( get_post_meta( $game->ID, \'score_value\', true ) ),
            );
        }
        // cache for 10 minutes
        set_transient( \'shortscore_recent_rated_games\', $result, 60 * 10 );
    }


    $response = new WP_REST_Response( $result );
    $response->header( \'Access-Control-Allow-Origin\', apply_filters( \'shortscore_access_control_allow_origin\', \'*\' ) );

    return $response;
}

这很好，但在这种情况下，我必须自己添加分页。

这是正确的方法吗？难道我不能扩展主查询，用x-headers和所有东西免费获得分页之类的东西吗？你会如何处理这个问题？将分页添加到此自定义端点，或者是否有方法使用分页的标准参数扩展WP-JSON的主查询？
