实用的Zend_ACL + Zend_Auth实施和最佳实践 [英] Practical Zend_ACL + Zend_Auth implementation and best practices
本文介绍了实用的Zend_ACL + Zend_Auth实施和最佳实践的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
上下文:
我的问题与我正在开发的论坛非常相似，就像这样:
- 有权查看主题但无法回复或投票的来宾
- 具有足够代表资格的成员可以编辑/投票其他线程，并且默认情况下，他们可以答复并具有与来宾相同的特权
- 几乎可以做任何事情的管理员
我希望将此ACL应用于整个站点，并且默认情况下拒绝所有资源.
我阅读了使用Zend_Acl的基础知识-您基本上可以创建角色(guest，member，admin)，并拒绝或允许资源(控制器，方法)使用这些角色.有关如何在应用程序中实际实现ACL代码的文档，它不是很具体，所以我一直在研究SO ..
在非常有用的stackoverflow上出现 marek的答案在这个问题上，但是由于我不熟悉，我仍然无法完全理解如何正确地实现最佳实践.
发布者在应用程序根目录中有一个静态文件configAcl.php，该文件初始化acl对象，添加角色，从每个控制器中创建资源，为admin提供对所有内容的访问权，为normal对除内容以外的所有内容的访问权admin并将acl对象存储在注册表中以供以后使用.
$acl = new Zend_Acl();
$roles = array('admin', 'normal');
// Controller script names. You have to add all of them if credential check
// is global to your application.
$controllers = array('auth', 'index', 'news', 'admin');
foreach ($roles as $role) {
$acl->addRole(new Zend_Acl_Role($role));
}
foreach ($controllers as $controller) {
$acl->add(new Zend_Acl_Resource($controller));
}
// Here comes credential definiton for admin user.
$acl->allow('admin'); // Has access to everything.
// Here comes credential definition for normal user.
$acl->allow('normal'); // Has access to everything...
$acl->deny('normal', 'admin'); // ... except the admin controller.
// Finally I store whole ACL definition to registry for use
// in AuthPlugin plugin.
$registry = Zend_Registry::getInstance();
$registry->set('acl', $acl);
问题#1 -该代码应该在引导程序中，还是在这样的独立文件中?如果是这样的话，最好是在库目录之内?
第二部分是扩展Zend Controller Plugin Abstract类的新类，该类允许将其挂接到auth/login中，逻辑基本上是如果登录失败，它将重定向..否则它将从acl对象中获取acl对象.注册表，获取身份，并确定是否允许用户查看此资源.
$identity = $auth->getIdentity();
$frontController->registerPlugin(new AuthPlugin());
问题#2 -我将如何对真正返回用户身份的auth插件部分进行编码?我意识到他下面有一些代码可以生成Auth适配器db表对象，该对象将通过用户ID和凭据(哈希通过检查)来查询数据库表的列. /p>
假设我的用户表由以下数据组成:
user_id user_name level
1 superadmin 3
2 john 2
3 example.com 1
其中级别3 =管理员，级别2 =成员，级别1 =来宾.
问题#3 -将上面的身份验证代码放入的确切位置是哪里?在登录控制器内部?
问题4 -另一个张贴者解决方案
我的实现:

Zend_View_Helper_Navigation_HelperAbstract::setDefaultRole(Smapp::getCurrentUser()->role);
Zend_Registry::set('Zend_Acl', $acl);
return $acl;
}
和Front_Controller_Plugin
class App_Plugin_Auth extends Zend_Controller_Plugin_Abstract
{
private $_identity;
/**
* the acl object
*
* @var zend_acl
*/
private $_acl;
/**

'action' => 'no-auth');
/**

*
* @var unknown_type
*/
private $_noauth = array('module' => 'users',
'controller' => 'auth',
'action' => 'login');
/**
* validate the current user's request
*
* @param zend_controller_request $request
*/
public function preDispatch(Zend_Controller_Request_Abstract $request)
{
$this->_identity = Smapp::getCurrentUser();
$this->_acl = App_Model_Acl::getInstance();
if (!empty($this->_identity)) {
$role = $this->_identity->role;
} else {
$role = null;
}
$controller = $request->controller;
$module = $request->module;
$controller = $controller;
$action = $request->action;
//go from more specific to less specific
$moduleLevel = 'mvc:'.$module;
$controllerLevel = $moduleLevel . '.' . $controller;
$privelege = $action;
if ($this->_acl->has($controllerLevel)) {
$resource = $controllerLevel;
} else {
$resource = $moduleLevel;
}
if ($module != 'default' && $controller != 'index') {
if ($this->_acl->has($resource) && !$this->_acl->isAllowed($role, $resource, $privelege)) {
if (!$this->_identity) {
$request->setModuleName($this->_noauth['module']);
$request->setControllerName($this->_noauth['controller']);
$request->setActionName($this->_noauth['action']);
//$request->setParam('authPage', 'login');
} else {
$request->setModuleName($this->_noacl['module']);
$request->setControllerName($this->_noacl['controller']);
$request->setActionName($this->_noacl['action']);
//$request->setParam('authPage', 'noauth');
}
throw new Exception('Access denied. ' . $resource . '::' . $role);
}
}
}
}
最后-Auth_Controller`:)
class Users_AuthController extends Smapp_Controller_Action
{
//sesssion
protected $_storage;
public function getStorage()
{
if (null === $this->_storage) {
$this->_storage = new Zend_Session_Namespace(__CLASS__);
}
return $this->_storage;
}
public function indexAction()
{
return $this->_forward('login');
}
public function loginAction()
{
$openId = null;
if ($this->getRequest()->isPost() and $openId = ($this->_getParam('openid_identifier', false))) {
//do nothing
} elseif (!isset($_GET['openid_mode'])) {
return;
}
//$userService = $this->loadService('User');
$userService = new Users_Service_User();
$result = $userService->authenticate($openId, $this->getResponse());
if ($result->isValid()) {
$identity = $result->getIdentity();
if (!$identity['Profile']['display_name']) {
return $this->_helper->redirector->gotoSimpleAndExit('update', 'profile');
}
$this->_redirect('/');
} else {
$this->view->errorMessages = $result->getMessages();
}
}
public function logoutAction()
{
$auth = Zend_Auth::getInstance();
$auth->clearIdentity();
//Zend_Session::destroy();
$this->_redirect('/');
}
}
问题2
将其保留在Zend_Auth内.
-在存储中写入身份. $auth->getStorage()->write($result->getIdentity());
identity-就是user_id

有问题吗? :)
Context:
My questions pertain to a forum I'm developing pretty much exactly like SO, where there are:
- guests who have access to view threads but can't reply or vote
- members who, with enough rep, can edit/vote others threads, and by default they can reply and have the same privileges as guests
- admins who can pretty much do anything
I would want this ACL to be applied site-wide, and by default deny all resources.
I read the basics of using Zend_Acl - in that you basically create roles ( guest, member, admin ) and either deny or allow resources ( controllers, methods ) to those roles. The documentation isn't very specific on how you should actually implement the acl code in your application, so I went looking on SO..
Came across a pretty useful stackoverflow answer from marek which sheds some light on the issue, however due to my unfamiliarity I still can't fully grok how to properly implement this with best practices in mind.
The poster has a static file configAcl.php in the application root which initializes the acl object, adds roles, creates a resource out of every controller, gives admin access to everything, gives normal access to everything but the admin and stores the acl object in the registry for later use.
$acl = new Zend_Acl();
$roles = array('admin', 'normal');
// Controller script names. You have to add all of them if credential check
// is global to your application.
$controllers = array('auth', 'index', 'news', 'admin');
foreach ($roles as $role) {
$acl->addRole(new Zend_Acl_Role($role));
}
foreach ($controllers as $controller) {
$acl->add(new Zend_Acl_Resource($controller));
}
// Here comes credential definiton for admin user.
$acl->allow('admin'); // Has access to everything.
// Here comes credential definition for normal user.
$acl->allow('normal'); // Has access to everything...
$acl->deny('normal', 'admin'); // ... except the admin controller.
// Finally I store whole ACL definition to registry for use
// in AuthPlugin plugin.
$registry = Zend_Registry::getInstance();
$registry->set('acl', $acl);
Question #1 - Should this code be in the bootstrap, or in a standalone file such as this? If so would it be better if it was inside say, the library directory?
The second part of it is a new class extending the Zend Controller Plugin Abstract class which allows it to be hooked into auth/login, the logic is basically if the login fails, it redirects.. otherwise it grabs the acl object from the registry, grabs the identity, and determines if the user is allowed to view this resource.
$identity = $auth->getIdentity();
$frontController->registerPlugin(new AuthPlugin());
Question #2 - How exactly would I code the auth plugin part that actually returns the identity of the user? I realize that he had some code below that generated a Auth adapter db table object which would query a database table's column by user id and credential ( hashed pass check ).. I'm confused on where this fits in with the getIdentity part.
Let's say my users table was composed of this data:
user_id user_name level
1 superadmin 3
2 john 2
3 example.com 1
Where level 3 = admin, 2 = member, 1 = guest.
Question #3 - where exactly is a good place to put the above auth code in? Inside of the login controller?
Question #4 - another poster replies with his article on how the acl logic should be done inside models, yet the specific method which he uses is not natively supported and requires a workaround, is this feasible? And is this really how it ideally should be done?

}
public function logoutAction()
{

//Zend_Session::destroy();
$this->_redirect('/');
}
}
Question #2
keep it inside Zend_Auth.
after succesfull auth - write identity in storage. $auth->getStorage()->write($result->getIdentity());
the identity - is simply user_id
DB design
CREATE TABLE `user` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`open_id` varchar(255) NOT NULL,
`role` varchar(20) NOT NULL,
`last_access` datetime NOT NULL,
