Laravel 4 except filter in controller constructor
提问by JasonMortonNZ
Currently I have an AdminContoller with a construct method handling some of the before filters. Is there a way to do a before filter on all controller methods except one?
目前我有一个 AdminContoller，它有一个构造方法来处理一些之前的过滤器。有没有办法对除一个以外的所有控制器方法进行前置过滤？
I'm using Entrust for Roles and Permissions, but this code is throwing me into an infinite redirect loop. I'm not logged in as a user at all. So this code should redirect me to the /admin/login url which is attached to an unfiltered AdminController@adminLogin method. But it doesn't?
我将 Entrust 用于角色和权限，但此代码使我陷入无限重定向循环。我根本没有以用户身份登录。所以这段代码应该将我重定向到 /admin/login url，它附加到一个未过滤的 AdminController@adminLogin 方法。但它没有？
// AdminController.php file
// AdminController.php 文件
class AdminController extends BaseController {
function __construct() {
// Is something like this possible?
$this->beforeFilter('admin', array('except' => array('adminLogin')));
$this->beforeFilter('csrf', array('on' => 'post'));
}
public function index()
{
return "Admin - Index";
}
public function adminLogin()
{
return "Admin Login Form";
}
// ... and many more methods
}
// Filter.php file
//过滤器.php文件
Route::filter('admin', function()
{
if( !Entrust::hasRole('admin') ) // Checks the current user
{
return Redirect::to('/admin/login');
}
});
// Routes.php file
// Routes.php 文件
Route::resource('admin', 'AdminController');
Route::get('/admin/login', 'AdminController@adminLogin');

As you've added a new method into a resourceful controller, you should register the new method first, before the resource.
当您将新方法添加到资源丰富的控制器中时，您应该先注册新方法，然后再注册资源。
E.g.
例如
<?php // Routes.php
Route::get('/admin/login', 'AdminController@adminLogin');
Route::resource('admin', 'AdminController');
This way your before filters should work as you have then like this:
这样你的前过滤器应该像你那样工作：
<?php // AdminController.php
class AdminController extends BaseController {
function __construct() {
$this->beforeFilter('admin', array('except' => array('adminLogin')));
$this->beforeFilter('csrf', array('on' => 'post'));
}
}

Yes, it's possible, because there is an public $except;and public $only;property in Filterclass in vendor/laravel/framework/src/Illuminate/Routing/Controllers/Filter.phpfile and you can also use onlyinstead of exceptto use a filter only on specific methods.
是的，这是可能的，因为文件中的类中有一个public $except;andpublic $only;属性，您也可以使用而不是仅在特定方法上使用过滤器。Filtervendor/laravel/framework/src/Illuminate/Routing/Controllers/Filter.phponlyexcept
From L4docs for only
来自L4文档only
$this->afterFilter('log', array('only' => array('fooAction', 'barAction')));
So, this should work too
所以，这也应该有效
$this->beforeFilter('log', array('except' => array('fooAction', 'barAction')));
In L3I've used
在L3我用过
$this->filter('before', 'auth')->except(array('login', 'login_ajax', 'fb_login'));
but didn't use in L4but it should work, according to source code and the doc.
但没有使用 inL4但它应该可以工作，根据源代码和文档。
