CodeIgniter在每个控制器中验证用户 [英] CodeIgniter authenticate the user in every Controller

问题描述

我在Codeigniter建立第一个专案，使用 Tank_auth 来处理我的CMS验证。

关于最佳实践的问题。目前，每个控制器中的每个函数具有以下结构：

  public function add（）
 {
 if（$ this-> tank_auth-> is_logged_in（））
 {
 
 $ data ['stuff'] ='stuff' 
 
 $ this-> load-> view（'admin / cms_add'，$ data）; 
 
 
} else 
 {
 redirect（'/ admin / login /'）; 
} 
} 
  

有很多控制器，每个，它开始重复，我想知道这是否是正确的方法去，或者如果有一个更清洁的方法，确保非登录用户不能访问这些功能。

如果每个控制器中的每个方法

code>应检查用户是否已登录，您可以在每个控制器中使用 __ construct（）方法如下：

  public function __construct（）
 {
 parent :: __ construct（）; 
 
 if（！$ this-> tank_auth-> is_logged_in（））{
 redirect（'/ admin / login /'）; 
} 
} 
  

您还可以扩展CI控制器并创建自定义 MY_Controller 并检查其中的if语句。那么控制器只接受已登录的用户，应该继承 My_Controller ：

应用程序/core/MY_Controller.php ：

  class MY_Controller extends CI_Controller {
 
 public function __construct（）
 {
 //执行CI_Controller构造函数
 parent :: __ construct（）; 
 
 if（！$ this-> tank_auth-> is_logged_in（））{
 redirect（'/ admin / login /'）; 
} 
} 
} 
  

application / controllers / welcome.php ：

  class Welcome extends MY_Controller {
 
 function __construct（）
 {
 parent :: __ construct（）; 
} 
 
 function index（）
 {
 $ this-> load-> view（'welcome_message'）; 
} 
}

I'm building my first project in Codeigniter, using Tank_auth to handle my CMS authentication.

It's working ok but I have a question about best practices. Currently, every function in every controller has the following structure:

public function add()
    {
        if ($this->tank_auth->is_logged_in())
        {

            $data['stuff'] = 'stuff';

            $this->load->view('admin/cms_add',$data);


        } else
        {
            redirect('/admin/login/');  
        }
    }

With quite a few controllers, and a few functions in each, it's starting to get repetitive, and I wonder if this is the correct way to go about it, or if there's a cleaner method of ensuring non-logged in users can't access these functions.

Thanks in advance.

解决方案

If every method in every controller should check whether user is logged-in, you can use __construct() method in each controllers as the following:

public function __construct()
{
    parent::__construct();

    if (! $this->tank_auth->is_logged_in()) {
        redirect('/admin/login/');
    }
}

You can also extend the CI Controller and create a custom MY_Controller and check the if statement inside. then the Controllers only accept logged-in users, should inherit the My_Controller:

application/core/MY_Controller.php:

class MY_Controller extends CI_Controller {

    public function __construct()
    {
        // Execute CI_Controller Constructor
        parent::__construct();

        if (! $this->tank_auth->is_logged_in()) {
            redirect('/admin/login/');
        }
    }
}

application/controllers/welcome.php:

class Welcome extends MY_Controller {

    function __construct()
    {
        parent::__construct();
    }

    function index()
    {
        $this->load->view('welcome_message');
    }
}
