HomeBackend DevelopmentPHP TutorialCI框架中通过hook的方式实现简单的权限控制_PHP

根据自己的实际情况,需要两个文件,一个是权限控制类,Acl,另外一个是权限配置的文件acl.php放在了config这个目录下。

Acl这个类放在了application/hook/acl.php。通过application/config/config.php文件开启hook,并且配置config这个目录下的hook.php文件。

1、开启hook功能,config.php这个文件

代码如下:


/*
|--------------------------------------------------------------------------
| Enable/Disable System Hooks
|--------------------------------------------------------------------------
|
| If you would like to use the 'hooks' feature you must enable it by
| setting this variable to TRUE (boolean).  See the user guide for details.
|
*/
$config['enable_hooks'] = TRUE;

2、配置hook.php这个文件

代码如下:


/*
| -------------------------------------------------------------------------
| Hooks
| -------------------------------------------------------------------------
| This file lets you define "hooks" to extend CI without hacking the core
| files.  Please see the user guide for info:
|
|    http://codeigniter.com/user_guide/general/hooks.html
|
*/
$hook['post_controller_constructor'] = array(
    'class'    => 'Acl',
    'function' => 'auth',
    'filename' => 'acl.php',
    'filepath' => 'hooks'
);

具体的参数说明可以参看文档的链接地址,这里尤其要注意post_controller_constructor这个值,可以根据情况选择不同的。

3、编写权限配置文件acl.php放在config目录下。

代码如下:


$config['AUTH'] = array(
    SUPER_ADMIN         => array(
        'admin' => array('index', 'logout'),
    ),
    ADMIN   => array(
        'admin' => array('index', 'logout'),
    ),
    GUEST => array(
        'admin' => array('index', 'logout'),
    ),
);

这里只是我根据自己的情况定义的,不是真实数据,根据自己的情况定。还有主要变量名字要交$config,这样便于加载使用。

4、编写具体的权限控制Acl类

代码如下:


class Acl {
    private $url_model;
    private $url_method;
    private $CI;
    function Acl()
    {
        $this->CI =& get_instance();
        $this->CI->load->library('session');
        $this->url_model = $this->CI->uri->segment(1);
        $this->url_method = $this->CI->uri->segment(2);
    }
    function auth()
    {
        $user = $this->CI->session->userdata('USER');
        if(empty($user))
            $user->status = 0;
        $this->CI->load->config('acl');
        $AUTH = $this->CI->config->item('AUTH');
        if(in_array($user->status, array_keys($AUTH))){
            $controllers = $AUTH[$user->status];
            if(in_array($this->url_model, array_keys($controllers))){
                if(!in_array($this->url_method, $controllers[$this->url_model])){
                    show_error('您无权访问该功能,该错误已经被记录!点击返回');
                }
            }else{
                show_error('您无权访问该模块,该错误已经被记录!点击返回');
            }
        }
        else
            show_error('错误的用户类型,该错误已经被记录!点击返回');
    }
}

整体上大体是这样的形式,最后还是要根据自己的实际情况来确定。

需要注意的是:

代码如下:


$this->CI =& get_instance();

以上只是实现了简单的权限控制,小伙伴们可以根据自己的需求,自由扩展下吧。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
