codeIgniter只允许访问特定的控制器登录时 [英] CodeIgniter only allow access to certain controllers when logged in

问题描述

我有只应由谁已经登录的用户访问一些codeIgniter控制器（即，其中$这个 - >会话级>用户数据（用户名）不为空）。如果非认证的人试图访问所述控制器，他们应获得：

I have some CodeIgniter controllers which should only be accessed by users who have logged in (i.e. where $this->session->userdata('username') is not null). If a non-authenticated person attempts to access said controllers they should receive:

header('location: /auth/login');

有一定是更好的方法来做到这一点，而不是把

There has got to be a better way to do this than to put a

if (!$this->session->userdata('username'))
    header('location: /auth/login');
else
{
    [rest of function]
}

在控制器各功能的前...

in front of every function in the controller...

我知道DX_Auth也有类似的功能，但我不使用身份验证的插件，我不开这样做。

I know DX_Auth has a similar functionality, but I am not using an authentication plugin and I am not open to doing so.

谢谢！结果

推荐答案

执行用户登录检查创建类的时候，所以也无所谓什么功能的用户访问，将检查会话变量并重定向到在失败的登录页面：

Do the user login check when the class is created, so it doesn't matter what function the user is accessing it will check for the session variable and redirect to the login page on failure:

function className()
{
    parent::Controller();
    if(!$this->session->userdata('username')) header('location: /auth/login');
}

这是调用的 __构造的方式或在创建它在codeigniter相当于控制器/型号 ，或者至少这是我的理解！

That's the way of calling the __constructor or it's equivalent in codeigniter when you create controllers/models, or at least that's what I understood!
