有没有办法在AJAX输出中使用Wordpress函数并将返回的对象作为参数传递？

define('WP_USE_THEMES', false);
require_once('wp-load.php');

$post_id = $_POST['post_id'];
$post = get_post($post_id);
$title = $post->post_title;
$content = $post->post_content;

$response = array(
    'title' => $title,
    'content' => $content
);
wp_send_json($response);

$.ajax({
    url: 'ajax-handler.php',
    type: 'POST',
    data: {
        post_id: 123
    },
    success: function(response) {
        var title = response.title;
        var content = response.content;
        // 在页面上显示标题和内容
        $('#title').text(title);
        $('#content').html(content);
    }
});
