Laravel 自动生成验证的实例讲解:login / logout

Laravel 自动授权讲解

看到这部分文档,经常看见的一句话就是php artisan make:auth,经常好奇这段代码到底干了什么,现在就来扒一扒。

路由

路由文件中会新加入以下内容:

Auth::routes();
Route::get('/home','HomeController@index')->name('home');

首先先是Auth::route();,这句代码等于以下全部设置(文件位置是\Illuminate\Routing\Router.php):

/**
  * Register the typical authentication routes for an application.
  *
  * @return void
  */
 public function auth()
 {
  // Authentication Routes...
  $this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
  $this->post('login', 'Auth\LoginController@login');
  $this->post('logout', 'Auth\LoginController@logout')->name('logout');

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

  // Password Reset Routes...
  $this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
  $this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail')->name('password.email');
  $this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm')->name('password.reset');
  $this->post('password/reset', 'Auth\ResetPasswordController@reset');
 }

这一部分先讲注册,首先,可以看到登录(login)的路由指向的是Auth\LoginController@showLoginForm,这个控制器是app\Http\Auth\LoginController.php,这里贴一下他的代码:

class LoginController extends Controller
{
 /*
 |--------------------------------------------------------------------------
 | Login Controller
 |--------------------------------------------------------------------------
 |
 | This controller handles authenticating users for the application and
 | redirecting them to your home screen. The controller uses a trait
 | to conveniently provide its functionality to your applications.
 |
 */

 use AuthenticatesUsers;

 /**
  * Where to redirect users after login.
  *
  * @var string
  */
 protected $redirectTo = '/home';

 /**
  * Create a new controller instance.
  *
  * @return void
  */
 public function __construct()
 {
  $this->middleware('guest')->except('logout');
 }
}

而其中并没有设置showLoginForm方法,该方法被保存在trait AuthenticatesUsers中,该方法的代码如下:

public function showLoginForm()
 {
  return view('auth.login');
 }

就是返回一个视图,下面我们来看该视图:

<form class="form-horizontal" method="POST" action="{{ route('login') }}">
</form>
