laravel 5.2 user authentication problem

Question

Version: laravel 5.2

After user authentication is turned onRoute::auth()method will automatically register the route:

//Illuminate/Routing/Router类的auth方法
public function auth()
{
    // Authentication Routes...
    $this->get('login', 'Auth\AuthController@showLoginForm');
    $this->post('login', 'Auth\AuthController@login');
    $this->get('logout', 'Auth\AuthController@logout');

    // Registration Routes...
    $this->get('register', 'Auth\AuthController@showRegistrationForm');
    $this->post('register', 'Auth\AuthController@register');

    // Password Reset Routes...
    $this->get('password/reset/{token?}', 'Auth\PasswordController@showResetForm');
    $this->post('password/email', 'Auth\PasswordController@sendResetLinkEmail');
    $this->post('password/reset', 'Auth\PasswordController@reset');
}

Generate AuthController controller:

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
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?
    |
    */

    use AuthenticatesAndRegistersUsers, ThrottlesLogins;

    /**
     * Where to redirect users after login / registration.
     *
     * @var string
     */
    protected $redirectTo = '/';//户成功进行登录认证后，默认将会跳转到路径

    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware($this->guestMiddleware(), ['except' => 'logout']);
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

Why does this AuthController controller not define login, logout and other methods, but these methods have output when accessing localhost/login? Where are these methods defined?

What's going on?

Used

trait AuthenticatesAndRegistersUsers

Click on the open source code and you will know.

Does it have to be like this

====Learn laravel here: https://laravist.com====

Click on AuthenticatesAndRegistersUsers, it will probably look like this:

trait AuthenticatesAndRegistersUsers
{
    use AuthenticatesUsers, RegistersUsers {
        AuthenticatesUsers::redirectPath insteadof RegistersUsers;
        AuthenticatesUsers::getGuard insteadof RegistersUsers;
    }
}

Click it againAuthenticatesUsers, and a bunch of methods will appear.
