第二次请求电子邮件验证时未收到电子邮件

Question

最近，我从this blog post发送了我的网络应用中的电子邮件验证 我的应用程序运行良好，我也在用户注册时收到一封电子邮件，但是当我尝试登录而未激活时，我必须从我的应用程序收到其他电子邮件，但它不会发送它。我错过了一些东西，但我没有找到帮助来解决这个问题。

这是我的AuthController

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\ActivationService;

use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

class AuthController extends Controller
{
    /*

    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
