我有一个如下的 MySQL 数据库表，即资源表：

+----+-----------+------------+
| 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，但我试图全面了解我正在尝试做的事情。所以它的工作方式，一个角色（又名用户）可以被授予 （规则：1）访问控制器，一个角色可以继承 （规则：3）从另一个角色或角色访问并被拒绝 （规则：2）访问到控制器。（用户是资源，控制器是资源）

使用 extras 列授予/拒绝访问操作。

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。

因此，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 persudo 代码示例也是一个有用的起点——这是我正在拼凑的拼图的最后一部分。

PS显然我有 ACL 对象 - 是更容易查询它还是通过 PHP/MySQL 自己做更好？

目的是，显示角色可以访问的内容，然后允许我以 GUI 样式添加或编辑角色、控制器和操作（这有点容易） - 目前我正在手动更新数据库建设网站。

好吧，在我进行了一些搜索但找不到答案之后，我对此进行了更多思考，这是我想出的解决方案（以防它对其他人有用）：

伪第一：

  1. 显示一个页面，将 ACL中的所有角色 （用户级别）$acl->getRoles()作为链接列出。
  2. 单击一个链接，重新加载将角色作为参数传递的页面。
    • 现在从 ACL中获取所有控制器$acl->getResources()，检查资源是否不是角色（getResources 返回的数组也将包含角色）。
    • 遍历每个控制器，从规则表中获取所有条目，其中控制器id 在 resource_id 字段中，并展开额外内容 （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），否则将其着色为红色（无法访问该控制器中的任何内容）每个列表项都可以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，当运行动作列表时，调用isAllowed我为所选控制器创建动作列表，根据结果将动作着色为绿色或红色isAllowed

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：

现在看代码：

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;
    }   
}

接下来是视图：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 
                $array = $this->actions;
                sort($array);
                foreach ($array as $action)
                {
                    $font = ($action['allowed'])?'green':'red';
                    echo '<li><font style="color:'.$font.';">'.ucfirst($action['action']).'</font></li>';
                }
            ?>
        </ul>
    <?php endif;?>
<?php endif; ?>
