zend-framework - Zend Acl 数据库驱动加载所有数据

Question

我一直在阅读 Zend 框架的 Zend_Acl 组件。我想实现一个数据库驱动的解决方案，但注意到我已经从数据库中加载所有角色、权限和资源来构建 ACL。根据需要将这些规则延迟加载到 ACL 中看起来并不容易或不可能。看起来如果实现了任何延迟加载，整个 Zend_Acl 类都必须被删除。有没有人有一个很好的例子来说明如何做到这一点？

The approach I would recommend is to build the ACL from the DB and cache it with Zend_Cache so it doesn't need to be loaded with every request.

Firstly, build the ACL object with $acl = new Zend_Acl(); Then get your roles, resources and permissions from the DB. Loop through your resources and roles and add them with $acl->addResource() and $acl->addRole(), then add permissions with $acl->allow()

Assuming you have bootstrapped your $cache object and it is available here (via Zend_Registry or whatever), do something like:

if (($acl = $cache->load('acl')) === false) {
  $acl = $this->_buildACL(); // Build you ACL in the _buildAcl() method
  $cache->save($acl, 'acl', array('ACL'));
}
Zend_Registry::set('acl', $acl);
