自定义帖子类型REST API自定义endpoint，用于按ID的单个帖子

Question

我创建了一个WordPress自定义帖子类型，然后我创建了REST API自定义endpoint以获取所有帖子运行良好。然后我创建了另一个自定义endpoint以按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($id) { 

    $args = [
         'post_type' => 'cars',
         'id' => $id['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;
}

请使用WP_REST_Request $request使参数通过。

public function rest_endpoint_handler_single(WP_REST_Request $request) { 

    $params = $request->get_query_params();

    $args = [
         'post_type' => 'cars',
         'numberposts' => 1,
         'include' => array($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;
}
