Laravel 4除了控制器构造函数中的过滤器 [英] Laravel 4 except filter in controller constructor

问题描述

当前，我有一个带有构造方法的AdminContoller，该方法处理一些以前的过滤器.是否可以对除一个以外的所有控制器方法进行事前过滤?

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?

我正在使用Entrust的角色和权限，但是这段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.因此，此代码应将我重定向到/admin/login URL，该URL附加到未过滤的AdminController @ adminLogin方法.但这不是吗?

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?

//AdminController.php文件

// AdminController.php file

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文件

// Filter.php file

Route::filter('admin', function()
{
    if( !Entrust::hasRole('admin') ) // Checks the current user
    {
        return Redirect::to('/admin/login');
    }
});

//Routes.php文件

// Routes.php file

Route::resource('admin', 'AdminController');

Route::get('/admin/login', 'AdminController@adminLogin');

推荐答案

在将新方法添加到资源丰富的控制器中后，您应该先在资源之前注册新方法.

As you've added a new method into a resourceful controller, you should register the new method first, before the resource.

例如

<?php // Routes.php

Route::get('/admin/login', 'AdminController@adminLogin');
Route::resource('admin', 'AdminController');

这样，您的before过滤器应可以像这样正常工作:

This way your before filters should work as you have then like this:

<?php // AdminController.php
   class AdminController extends BaseController {
     function __construct() {
       $this->beforeFilter('admin', array('except' => array('adminLogin')));
      $this->beforeFilter('csrf', array('on' => 'post'));
    }
}
