【问题描述】:

我有一个 MySQL 数据库表,如下所示,资源表

+----+-----------+------------+
| id | name      | type       |
+----+-----------+------------+
| 1  | guest     | user       |
| 2  | member    | user       |
| 3  | moderator | user       |
| 4  | owner     | user       |
| 5  | admin     | user       |
| 6  | index     | controller |
+----+-----------+------------+

在下一张表上,规则表

+----+---------+------+-------------+----------------------+
| id | user_id | rule | resource_id | extras               |
+----+---------+------+-------------+----------------------+
| 1  | 2       | 3    | 1           | null                 |
| 2  | 3       | 3    | 2           | null                 |
| 3  | 4       | 3    | 3           | null                 |
| 4  | 5       | 3    | 4           | null                 |
| 5  | 6       | 1    | 1           | index,login,register |
| 6  | 6       | 2    | 2           | login,register       |
| 7  | 6       | 1    | 2           | logout               |
+----+---------+------+-------------+----------------------+

好的,抱歉篇幅太长,但我正在尝试全面介绍我正在尝试做的事情。 所以它的工作方式,一个角色(aka user)可以被授予 (规则:1)访问控制器,一个角色可以继承 (rule: 3) 从另一个角色或角色访问并被拒绝 (rule: 2) 访问控制器。 用户是一种资源,控制器是一种资源)

使用 extras 列授予/拒绝对操作的访问权限。

这一切都有效,在zend 中设置ACL 不是问题。


我现在要做的是展示关系;为此,我需要找到一个角色被授予访问控制器的最低级别,如果它已被明确删除。我计划列出角色。当我单击一个角色时,我希望它显示该角色有权访问的所有控制器。然后单击控制器会显示允许该角色执行的操作。

因此,在上面的示例中,访客可以查看索引控制器的索引操作以及登录操作。 成员继承相同的访问权限,但随后被拒绝访问登录操作和注册操作。 版主继承成员的规则。

所以如果我要选择角色版主。我想查看列出的控制器索引。如果我单击控制器,它应该将允许的操作显示为操作:索引。 (最初授予客人,但此后一直没有被拒绝)

有没有这样做的例子。我显然正在使用 Zend MVC (PHP) 和 MySQL。 即使只是一个伪代码示例也会是一个有用的起点 - 这是我正在拼凑的拼图的最后一部分。

P.S. 显然我有 ACL 对象 - 查询它会更容易还是通过 PHP/MySQL 自己做会更好?

目的是,显示一个角色可以访问什么,然后我可以添加或编辑一个 GUI 样式的角色、控制器和操作(这有点容易)——目前我正在更新手动数据库,因为我一直在构建网站。

    【解决方案1】:

    好吧,在我做了一些搜索,但找不到答案之后,我对此有了更多的思考,这是我想出的解决方案 (以防它对其他人有用)

    伪优先:

    1. 显示一个页面,将 ACL $acl->getRoles() 中的所有角色 (用户级别)作为链接列出。
    2. 单击一个链接,重新加载将角色作为参数传递的页面。
      • 现在从 ACL 中获取所有 控制器 $acl->getResources() 检查资源是否不是角色(getResources 返回的数组也将包含角色).
      • 循环遍历每个controller,从rules表中获取controller id在resource_id字段中的所有条目并分解extras (逗号分隔的操作)
      • 接下来,遍历每个动作,调用isAllowed(我有角色、控制器和动作)如果找到至少一个“允许”,我将控制器着色为绿色(允许访问控制器中的至少一个操作),否则为红色(否访问该控制器中的任何内容) 每个列表项都可单击以重新加载页面
    3. 现在,当单击控制器时,我重新加载页面,现在,当运行操作列表时,调用 isAllowed 我为所选控制器创建操作列表,根据isAllowed 的结果

    答案本身几乎与问题一样冗长,但它对我有用,非常清楚地说明了每个角色可以做什么。如果它可以帮助任何人,那就是:

    现在是代码:

    管理员控制器:

    public function aclAction()
    {
        $this->view->content_title = "Access Rules:";
    
        // Get the ACL - its stored in the session:
        $usersNs = new Zend_Session_Namespace("ZEND_SITE");
        $acl = $usersNs->acl;
    
        // List all Roles in the ACL:
        $roles = $acl->getRoles();
        // Pass the roles to the view:
        $this->view->roles = $roles;
    
        // Check if a role has been clicked on:
        $role = this->_getParam('role');
        if(!is_null($role))
        {
            // Pass the role to the view:
            $this->view->role = $role;
    
            // Get all the resources (controllers) from the ACL, don't add roles:
            $controllers = array();
            foreach ($acl->getResources() as $res)
            {
                if (!in_array($res, $roles))
                {
                    $controllers[] = $res;
                }
            }
    
            // Create a Rules Model:
            $rules = new Model_ACLrules();
    
            // Store controllers + access:
            $all_controllers = array();
    
            // Check if the controller has been passed:
            $cont = $this->_getParam('cont');
    
            // Loop through each controller:
            foreach ($controllers as $controller)
            {
                // Get all actions for the controller:
                // THIS IS THE PART I DON'T LIKE - BUT I SEE NO WAY TO GET
                // THE RULES FROM THE ACL - THERE LOOKS TO BE A METHOD
                // BUT IT IS A PROTECTED METHOD - SO I AM GETTING THE ACTIONS 
                // FROM THE DB, BUT THIS MEANS TWO SQL QUERIES - ONE TO FIND
                // THE RESOURCE FROM THE DB TO GET ITS ID THEN ONE TO FIND
                // ALL THE EXTRAS FOR IT:
                $all_rules = $rules->findAllActions($controller);
    
                // Store if the role is allowed access somewhere in the controller:
                $allowed = false;
    
                // Store selected controller actions:
                $cont_actions = array();
    
                // Loop through all returned row of actions for the resource:
                foreach ($all_rules as $rule)
                {
                    // Split the extras field:
                    $extras = explode(",", $rule->extras); 
    
                    // Check if the role has access to any of the actions:
                    foreach ($extras as $act)
                    {
                        // Store matching selected controller:
                        $match = ($cont==$controller)?true:false;
    
                        // Store the action if we are looking at a resource:
                        if ($match)$temp = array("action"=>$act,"allowed"=>false);
    
                        // Check if the role is allowed:
                        if ($acl->isAllowed($role,$controller,$act))
                        {
                            // Change the controllers allowed to ture as at least one item is allowed:
                            $allowed = true;
    
                            // Change the matched controllers action to true:
                            if ($match)$temp = array("action"=>$act,"allowed"=>true);
                        }
    
                        // Check if the action has already been added if we are looking at a resource:
                        if ($match)
                        {
                            $add = true;
                            // This is done because there could be several rows of extras, for example
                            // login is allowed for guest, then on another row login is denied for member,
                            // this means the login action will be found twice for the resource,
                            // no point in showing login action twice:
                            foreach ($cont_actions as $a)
                            {
                                // Action already in the array, don't add it again:
                                if ($a['action'] == $act) $add = false;
                            }
                            if($add) $cont_actions[] = $temp;
                        }
                    }
                }
    
                // Pass a list of controllers to the view:
                $all_controllers[] = array("controller" => $controller, "allowed" => $allowed);
    
                // Check if we had a controller:
                if(!is_null($cont))
                {
                    // Pass the selected controller to the view:
                    $this->view->controller = $cont;
    
                    // Check if this controller in the loop is the controller selected:
                    if ($cont == $controller)
                    {
                        // Add the controller + actions to the all rules:
                        $this->view->actions = $cont_actions;
                    }
                }
            }
    
            // Pass the full controller list to the view:
            $this->view->controllers = $all_controllers;
        }   
    }
    

    下一个视图:acl.phtml:

    <h2>Roles:</h2>
    <ul>
        <?php 
            foreach ($this->roles as $name)
            {
                echo '<li><a href="'.$this->baseUrl('admin/acl') . '/role/' . $name . '">' . ucfirst($name) . '</a><br/></li>';
            }
        ?>
    </ul>
    
    <?php if (isset($this->controllers)): ?>
        <h2><?php echo ucfirst($this->role); ?>'s Controllers:</h2>
        <ul>
            <?php
                $array = $this->controllers;
                sort($array);
                foreach ($array as $controller)
                {
                    $font = ($controller['allowed'])?'green':'red';
                    echo '<li><a href="'.$this->baseUrl('admin/acl') . '/role/' . $this->role . '/cont/'.$controller['controller'].'" style="color:'.$font.';">'.ucfirst($controller['controller']).'</a></li>';    
                }   
            ?>
        </ul>
    
        <?php if (isset($this->controller)): ?>
            <h2><?php echo ucfirst($this->role)."'s, ".ucfirst($this->controller);?> Actions:</h2>
            <ul>
                <?php

                    sort($array);
                    foreach ($array as $action)

                        $font = ($action['allowed'])?'green':'red';
                        echo '<li><font style="color:'.$font.';">'.ucfirst($action['action']).'</font></li>';
                    }

            </ul>
        <?php endif;?>
