我需要添加验证规则的文件类型字段。默认文件类型是.txt扩展名。我只想要允许.xls和.xlsx。这是提交的file，

$fields['my_new_file'] = BaseFieldDefinition::create('file') 
      ->setLabel(t('My New File')) 
      ->setDescription(t('The name of the Visaul tracker entity entity.')) 
      ->setDefaultValue('') 
      ->setDisplayOptions('view', array(
      'label' => 'above', 
      'type' => 'file', 
      'weight' => -4, 
     )) 
      ->setDisplayOptions('form', array(
      'type' => 'file', 
      'weight' => -4, 
     )) 
      ->setDisplayConfigurable('form', TRUE) 
      ->setDisplayConfigurable('view', TRUE);

请帮助我。

注意Drupal.StackExchange上的dupe问题有一些额外的信息。 https://drupal.stackexchange.com/questions/193402/validate-file-extension-in-drupal-8-entity-form/ – Christian

我挖Drupal的8核心API后得到了答案。如果我们使用的是文件字段，那么我们可以设置“file_extensions”设置。您可以通过访问FileItem API来了解有关“文件”类型的更多信息。

$fields['my_new_file'] = BaseFieldDefinition::create('file') 
    ->setSetting('file_extensions', 'xls xlsx');
