Laravel将激活链接发送到特定的电子邮件

我希望注册后的激活链接发送到一封电子邮件，这是因为我不希望每个人都创建一个管理员帐户，因此任何人创建一个管理员帐户，应用程序的所有者都会通过单击他的激活链接来激活他的帐户。电子邮件（所有者电子邮件）。

protected function postAdminRegistration(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:6|confirmed',
    ]);

    try {
        $validatedData['password'] = bcrypt(array_get($validatedData, 'password'));
        $validatedData['activation_code'] = str_random(30).time();
        $user = app(User::class)->create($validatedData);
    } catch (\Exception $exception) {
        logger()->error($exception);
        return redirect()->back()->with('message', 'Unable to create new user.');
    }
    $user->notify(new UserRegisteredSuccessfully($user));

    return redirect()->route("user.loginform")->withSuccess('Successfully created a new account.
        Please check your email and activate your account.');
}

用户注册成功

public function toMail($notifiable)
{
    $user = $this->user;

    return (new MailMessage)
        ->from('****@gmail.com')
        ->subject('Successfully created new account')
        ->greeting(sprintf('Hello %s', $user->fname))
        ->line('You have successfully registered to our system. Please activate your account.')
        ->action('Click Here',
            route('user.activate', $user->activation_code))->line('Thank you for using our application!');
}

模型

class User extends Authenticatable
{
use Notifiable;
protected $fillable = [
'name','email','password'
];

protected static $logFillable = true;
protected $hidden = [
    'password', 'remember_token',
];

public function sendPasswordResetNotification($token)
{
$this->notify(new ResetPassword($token.'/'.$this->email));
}
}
