Drupal 8-如何以编程方式创建用户帐户并在以后验证电子邮件地址

use Drupal\user\Entity\User;

// 创建一个新用户对象
$user = User::create();

// 设置用户名
$user->setUsername('new_user');

// 设置用户电子邮件地址
$user->setEmail('new_user@example.com');

// 设置用户密码
$user->setPassword('password');

// 保存用户对象
$user->save();

use Drupal\token\TokenEntityMapperInterface;
use Drupal\Core\Mail\MailManagerInterface;
use Drupal\Core\Language\LanguageManagerInterface;
use Drupal\Core\Render\RendererInterface;
use Drupal\Core\Url;

// 获取令牌生成器
$token_entity_mapper = \Drupal::service('token.entity_mapper');

// 生成验证令牌
$token = $token_entity_mapper->generate('user', 'email_verification', $user);

// 获取邮件管理器
$mail_manager = \Drupal::service('plugin.manager.mail');

// 获取语言管理器
$language_manager = \Drupal::service('language_manager');

// 获取渲染器
$renderer = \Drupal::service('renderer');

// 构建验证链接
$verification_url = Url::fromRoute('user.verify_mail', ['uid' => $user->id(), 'timestamp' => $user->getCreatedTime(), 'hash' => $token->value])->setAbsolute()->toString();

// 构建邮件主题
$subject = t('Please verify your email address');

// 构建邮件正文
$body = [
  '#markup' => t('Please click the following link to verify your email address: <a href=":url">:url</a>', [':url' => $verification_url]),
];

// 构建邮件头部
$headers = [
  'Content-Type' => 'text/html',
];

// 发送验证邮件
$mail_manager->mail('system', 'mail', $user->getEmail(), $language_manager->getDefaultLanguage()->getId(), ['message' => $body, 'subject' => $subject, 'headers' => $headers]);

use Drupal\Core\Utility\Token;
use Drupal\user\UserInterface;

// 获取令牌服务
$token_service = \Drupal::token();

// 验证令牌
$valid = $token_service->validate($token->value, ['user' => $user]);

if ($valid) {
  // 标记用户电子邮件地址为已验证
  $user->setEmailVerified(TRUE);
  $user->save();

  // 验证成功，执行其他操作
} else {
  // 验证失败，执行错误处理
}
