在Laravel中，如何使用'Route :: when（）'方法在所有路由上应用过滤器？

In Laravel 4, I found that if I want to attach a before filter to all routes of a website, I can use the App::before() method which exists in app/filters.php file, like this:

App::before(function($request)
{ 
    // my code here..
});

But because I discovered that I can't use Route::currentRouteName() method inside the App::before() method, I looked for another way to do this, and I found that I can create a custom filter in app/filters.php file, like this:

Route::filter('my_filter_name', function()
{
    // my code to apply on all routes..
});

And in app/routes.php file, I wrote the next pattern based filter:

Route::when('*', 'my_filter_name');

And it did exactly what I want, and I can use Route::currentRouteName() method as I want within my custom filter. But I noticed (and correct me if I'm wrong) that Route::when() method consider my_filter_name as a before filter. Now I want to know: How to use this Route::when() method to apply before and/or after filters?

You can do this

In your Routes

Route::group(array('before/after' => 'my_filter_name'), function()
{
    Route::get('/', function()
    {
        // Has my_filter_name Filter
    });

    Route::get('another', function()
    {
        // Has my_filter_name Filter
    });
});

Unfortunately Laravel gives you no possibility to add a pattern after filter with Route::when(). The proper way to do this is by wrapping your routes in a group:

Route::group(array('after' => 'my_filter_name'), function(){
    // routes
});

If you really really can't use a group, there is another solution. It's a bit hacky though...

After all routes are registered (normally at the bottom of routes.php) you can add this code that loops over all routes and adds the after filter to each route:

foreach(Route::getRoutes() as $route){
    $route->after('my_filter_name');
}
