学习使用Zend_Auth认证登陆

看了很多别人的文章，自己总结了下，做个笔记 Zend_Auth 只涉及认证而不是授权。授权使用Zend_Acl明天学习学习。
1）使用ZDE(zend Studio for eclipse 6)创建一个空的end framework项目。我使用sqlite数据库存储认证信息的。动态创建表和用户，只是测试吗。

<?php
/**
 * My new Zend Framework project
 *
 * @author
 * @version
 */

set_include_path('.' . PATH_SEPARATOR . '../library' . PATH_SEPARATOR . './application/default/models/' . PATH_SEPARATOR . get_include_path());
//require_once 'Zend/Controller/Front.php';

include "Zend/Loader.php";
Zend_Loader::registerAutoload();
/**
 * Setup controller
 */
$controller = Zend_Controller_Front::getInstance();
$controller->setControllerDirectory('../application/default/controllers');
$controller->throwExceptions(true); // should be turned on in development time


// 创建一个 in-memory SQLite 数据库连接

$dbAdapter = new Zend_Db_Adapter_Pdo_Sqlite(array('dbname' => ':memory:'));

// 构造一个简单表的创建语句

$sqlCreate = 'CREATE TABLE [users] ( '
           . '[id] INTEGER NOT NULL PRIMARY KEY, '
           . '[username] VARCHAR(50) UNIQUE NOT NULL, '
           . '[password] VARCHAR(32) NULL, '
           . '[real_name] VARCHAR(150) NULL)';

// 创建认证证书表

$dbAdapter->query($sqlCreate);

// 构造用来插入一行可以成功认证的数据的语句

$sqlInsert = 'INSERT INTO users (username, password, real_name) '
           . 'VALUES ("test", "test", "My Real Name")';

// 插入数据

$dbAdapter->query($sqlInsert);

// 用构造器参数来配置实例...

//$authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter, 'users', 'username', 'password');

Zend_Registry::set('authAdapter', $dbAdapter);

// run!

$controller->dispatch();


2）修改默认的IndexController.php

<?php

/**
 * IndexController - The default controller class
 *
 * @author
 * @version
 */

require_once 'Zend/Controller/Action.php';

class IndexController extends Zend_Controller_Action
{
    protected $_auth;
    protected $_userId;
    protected $_userName;
    
    public function init()
    {
        $this->_auth = Zend_Auth::getInstance()
             ->setStorage(new Zend_Auth_Storage_Session('authNameSpace'));
    }

    /**
     * The default action - show the home page
     */
    public function indexAction()
    {
        if ($this->_auth->hasIdentity()) {
                $this->_userId = $this->_auth->getStorage()->read()->id
                $this->_userName = $this->_auth->getStorage()->read()->username;
            //echo 'welcome ';

        } else {
            $this->_forward('login');
       }
    }
    
    public function loginAction()
    {
        if ($this->_request->isPost()) {
            $f = new Zend_Filter_StripTags();
            $username = $f->filter($this->_request->getParam('username'));
            $password = $f->filter($this->_request->getParam('password'));

            //建立认证适配器 (DB适配器名/表名/用户名字段/密码字段)

            $dbAdapter = Zend_Registry::get('authAdapter');
            //authAdapter在index.php中注册过了

            $authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter, 'users', 'username', 'password');
            $authAdapter->setIdentity($username)
                        ->setCredential($password);
            // do the authentication

            $auth = Zend_Auth::getInstance();
            $result = $auth->authenticate($authAdapter);
            //$result = $this->_auth->authenticate($authAdapter);


            //建立持久连接

            if ($result && $result->isValid()) {
                if ($this->_request->getParam('rememberMe')) { //记住密码

                    Zend_Session::rememberMe('315360000');//session过期时间

                } else {
                    Zend_Session::forgetMe();
                }
                $this->_auth->getStorage()->write($authAdapter->getResultRowObject(array('id', 'username')));
                $this->_redirect('/');
            } else {
                echo 'login error';
            }
        }

    }
}


3)在/views/scripts/index/下创建一个login.phtml

<h1><?php echo $this->escape($this->title); ?></h1>

<form action="index/login" method="post">
<div><label for="username">Username</label> <input type="text"
    name="username" value="" /></div>
<div><label for="password">Password</label> <input type="password"
    name="password" value="" /><br>
<input type="checkbox" name = "rememberMe"> rememberMe </div>
<div id="formbutton"><input type="submit" name="login" value="Login" />
</div>
</form>


别的不做什么修改就可以测试了，用户test,密码test.不选rememberMe复选框浏览器关闭就认证失效，选中了就在315360000秒后实效。呵呵。
