Laravel 控制器的middleware中间件
场景:活动开始前只能访问宣传页面,开始后才可以访问其他页面:
步骤:
新建中间件,
注册中间件,
使用中间件,
中间件的前置和后置操作。
控制器:
public function activity0(){
return '活动快要开始啦,敬请期待';
}
public function activity1(){
return '活动页面1';
}
public function activity2(){
return '活动页面2';
}
路由:
Route::any('activity0',['uses'=>'StudentController@activity0']);
Route::any('activity1',['uses'=>'StudentController@activity1']);
Route::any('activity2',['uses'=>'StudentController@activity2']);
在App\Http\Middleware下创建中间件Activity.php:
namespace App\Http\Middleware;
use Closure;
class Activity{
public function handle($request,Closure $next){
if(time() < strtotime('2018-01-01')){
return redirect('activity0');
}
return $next($request);
}
}
//注册中间件,在Kernel.php中的$routeMiddleware数组中增加
protected $routeMiddleware = [
'activity' => \App\Http\Middleware\Activity::class,
];
使用中间件,路由中的设置
//宣传页面不需要中间件验证,不能放里边
Route::any('activity0',['uses'=>'StudentController@activity0']);
Route::group(['middleware'=>['activity']],function(){
Route::any('activity1',['uses'=>'StudentController@activity1']);
Route::any('activity2',['uses'=>'StudentController@activity2']);
});
//后置中间件
public function handle($request,Closure $next){
$response = $next($request);
echo $response;
echo '我是后置操作';
}
