推荐答案

在这里，我为Drupal添加了等效语法7和Drupal 8

here i have added equivalent syntax for Drupal 7 and Drupal 8

file_usage_add    -> \Drupal::service('file.usage')->add
file_usage_delete -> \Drupal::service('file.usage')->delete
file_usage_list   -> \Drupal::service('file.usage')->listUsage


//Add / Delete file usage
$entity_type = 'node';
$entity_id = 1;//Node ID
$fid = 1; // The file ID
$file = \Drupal\file\Entity\File::load($fid);
$file_usage = \Drupal::service('file.usage');
$file_usage->add($file, 'mymodule', $entity_type, $entity_id);
$list = $file_usage->listUsage($file);
$file_usage->delete($file, 'mymodule', $entity_type, $entity_id)

//Get usage of a file
$file = \Drupal\file\Entity\File::load($fid);
$file_usage = \Drupal::service('file.usage');
$list = $file_usage->listUsage($file);
