创建自定义API端点，并将逻辑从PHP文件移到其中

例如，下面的代码将在中创建端点/wp-json/my/v1/video/<id>

add_action( \'rest_api_init\', function() {
  register_rest_route( \'my/v1\', \'/video/(?P<id>\\d+)\', [
    \'methods\'             => \'GET\',
    \'callback\'            => \'get_video_data\',
    \'permission_callback\' => \'__return_true\',
  ] );
} );

function get_video_data( $params ) {
  $video_id = $params[\'id\'];

  // do something like calling the DB where your video data is stored
  // you can use custom post type to store the data
  
  return $video_id;
}
