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

   \'App\Http\Middleware\AfterMiddleware\',

];

　　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

<?php


Route::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\',


与 Router.php 处的 路由 demo --> before 对应

Route::group([\'prefix\' => \'demo\'],function(){
    Route::get(\'before\', [\'as\'=>\'home.before.ware\' , \'uses\' => \'HomeController@before\']);
});

OK，写的不好之处，望指正
