自定义帖子类型API通过ID为单个帖子自定义endpoint

Question

我已经创建了一个WordPress自定义帖子类型，然后我创建了REST API自定义endpoint来让所有帖子正常工作。然后，我创建了另一个自定义endpoint，通过ID获取单个帖子。例如http://localhost:8888/WordPress/WP-JSON/LC/v1/cars/120

我已经创建了一些帖子，每次我将路线末端的ID更改为118或116时，它都会显示最新的post-ID 120的相同数据。我需要相关的数据来显示基于职位ID，我会感谢任何形式的帮助。谢谢

public function rest_posts_endpoints(){

 register_rest_route( 
    'lc/v1',
    '/cars/(?P<id>\d+)',
    [
        'method' => 'GET', 
        'callback' => [$this, 'rest_endpoint_handler_single'], 
    ]
);

}

public function rest_endpoint_handler_single( WP_REST_Request $request ) { 

$params = $request->get_query_params();

$args = [
     'post_type' => 'cars',
     'id' => $params['id'],
];

$post = get_posts($args);

    $data['id'] = $post[0]->ID;
    $data['slug'] = $post[0]->post_name;
    $data['title'] = $post[0]->post_title;
    $data['content'] = $post[0]->post_content;
    $data['excerpt'] = $post[0]->post_excerpt;

return $data;

}

public function rest_endpoint_handler_single( WP_REST_Request $request ) { 

$params = $request->get_params();

 $args = [
   'post_type' => 'cars',
   'id' => $params['id'],
   'include' => array($params['id']),
 ];

$post = get_posts($args);

$data['id'] = $post[0]->ID;
$data['slug'] = $post[0]->post_name;
$data['title'] = $post[0]->post_title;
$data['content'] = $post[0]->post_content;
$data['excerpt'] = $post[0]->post_excerpt;

return $data;
}
