laravel5 的中间件的使用 (1)

1.创建中间件

  php artisan make:middleware _Name_Middleware

 

2.注册中间件

  2.1 中间件注册在 Kennel.php 里面

  2.2 默认的存放在此处,会自动调用

     

/** * The application's global HTTP middleware stack. * * These middleware are run during every request to your application. * * @var array */protected $middleware = [    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,  #可在此处进行注册 如<br />
   'App\Http\Middleware\AfterMiddleware',
<br />];

 

  2.3 还有一种触发的方式,就是 从Route进行触发的

  2.3.1 首先需要注册他,即

  

    /**     * The application's route middleware.     *     * These middleware may be assigned to groups or used individually.     *     * @var array     */    protected $routeMiddleware = [        'auth' => \App\Http\Middleware\Authenticate::class,        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,        #注册一个 中间件        'demo.before'  => 'App\Http\Middleware\BeforeMiddleware',    ];

  他的使用和默认的有所不同,他想要在 router.php 中 使用 Router:: 的时候触发 

 

<?phpRoute::group(['middleware' => ['web']], function () {    Route::get('/', function () {        return view('welcome');    });    Route::group(['prefix' => 'demo'],function(){
          Route::get('after', ['as'=>'home.after.ware' , 'uses' => 'HomeController@after']);
 }); });

 

此处的代码是这样子的,当我们 访问的时候,他便会 进行自动使用中间件

 

3. 主要说说第二种方式的触发,可以看到

Kernel.php 处的 middleware 的 demo.before

       

'demo.before'  => 'App\Http\Middleware\BeforeMiddleware',<br /><br /><br />与 Router.php 处的 路由 demo --> before 对应
Route::group(['prefix' => 'demo'],function(){<br />    Route::get('before', ['as'=>'home.before.ware' , 'uses' => 'HomeController@before']);<br />});

 

OK,写的不好之处,往指正
