如果您使用的是WP 4.7+，则可以使用rest_$type_query 钩wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php:L267

这是一个按给定术语过滤当前查询的工作示例

    $types = [
        \'post\',
        \'page\',
    ];

    foreach ( $types as $type ) {
        add_filter( \'rest_\' . $type . \'_query\', \'filter_rest_query_by_zone\', 10, 2 );
    }

    function filter_rest_query_by_zone( $args, $request ) {
            $zones = [ \'term1\', \'term2\', \'term3\' ];

            $args[\'tax_query\'] = array(
                \'relation\' => \'AND\',
                array(
                    \'taxonomy\' => \'zones\',
                    \'field\'    => \'term_id\',
                    \'terms\'    => $zones
                )
            );

            return $args;
    }
