如何在Symfony中使用FOSUserBundle在自定义控制器中注册用户

如果你需要在symfony 2或3的自定义控制器中手动注册用户(无表单), 则只需访问控制器中的fos_user.user_manager服务即可。

你将要问自己, 为什么不简单地直接使用doctrine保留用户实体？答案很简单, 我们不想自己处理已经在FOSUserBundle中实现的加密内容。这就是为什么我们需要使用setPlainPassword方法访问服务。

注意：如果你不是从控制器手动实现用户插入, 则需要注入容器以便从任何位置检索fos_user服务。

class MyCustomuserController extends Controller
{
   public function registeruserAction(Request $request){
       $succesfullyRegistered = $this->register("demo@email.com", "demoUsername", "demoPassword");

       if($succesfullyRegistered){
           // the user is now registered !
       }else{
           // the user exists already !
       }
   }
 
   /**
    * This method registers an user in the database manually.
    *
    * @return boolean User registered / not registered
    **/
   private function register($email, $username, $password){    
      $userManager = $this->get('fos_user.user_manager');

      // Or you can use the doctrine entity manager if you want instead the fosuser manager
      // to find 
      //$em = $this->getDoctrine()->getManager();
      //$usersRepository = $em->getRepository("mybundleuserBundle:User");
      // or use directly the namespace and the name of the class 
      // $usersRepository = $em->getRepository("mybundle\userBundle\Entity\User");
      //$email_exist = $usersRepository->findOneBy(array('email' => $email));
      
      $email_exist = $userManager->findUserByEmail($email);

      // Check if the user exists to prevent Integrity constraint violation error in the insertion
      if($email_exist){
          return false;
      }

      $user = $userManager->createUser();
      $user->setUsername($username);
      $user->setEmail($email);
      $user->setEmailCanonical($email);
      $user->setLocked(0); // don't lock the user
      $user->setEnabled(1); // enable the user or enable it later with a confirmation token in the email
      // this method will encrypt the password with the default settings :)
      $user->setPlainPassword($password);
      $userManager->updateUser($user);

      return true;
   }
}
