YII 存放登录信息的类

如果在用户登录后想额外调用除 user,id之外的数据库变量，可以这样设置：

在登陆验证时候增加额外项：

在UserIdentity.php中

class UserIdentity extends CUserIdentity{
    $this->setState('last_login_time',$user->last_login_time);
}

如此，在应用程序的任何地方，这个属性可以通过如下获取：Yii::app()->user->getState('last_login_time')

再重新登录看看,

public function setState($key, $value, $defaultValue = null) {
    $key = $this->getStateKeyPrefix() . $key;
    if ($value === $defaultValue)
        unset($_SESSION[$key]);
    else
        $_SESSION[$key] = $value;
}

其实他将信息放到session中了

其中的user是yii的一个components.需要在protected/config/main.php中定义

'user'=>array(
        // enable cookie-based authentication
        'allowAutoLogin'=>true,
        'loginUrl' => array('site/login'),
),

通过扩展CWebUser添加信息到Yii:app()->user

步骤：1、添加$user属性到UserIdentity类。 添加getUser()方法-getter上面这个属性。加setUser($user)方法-setter上面这个属性，它可以赋值给user的信息通过$user这个属性。

用户信息存到数据库表里
我的UserIdentity类例子：

<?php
class UserIdentity extends CUserIdentity {
    /**
     * User's attributes
     * @var array
     */
    public $user;

    public function authenticate() {
        $this->errorCode = self::ERROR_PASSWORD_INVALID;
        $user = User::model()->findByAttributes(array('email' => CHtml::encode($this->username)));
        if ($user) {
            if ($user->password === md5($user->salt . $this->password)) {
                $this->errorCode = self::ERROR_NONE;
                $this->setUser($user);
            }
        }
        unset($user);
        return !$this->errorCode;
    }

    public function getUser() {
        return $this->user;
    }

    public function setUser(CActiveRecord $user) {
        $this->user = $user->attributes;
    }
}

?> 

现在用户的属性已经设置，创建WebUser类并把它放在/protected/components

<?php
class WebUser extends CWebUser {
    public function __get($name) {
        if ($this->hasState('__userInfo')) {
            $user = $this->getState('__userInfo', array());
            if (isset($user[$name])) {
                return $user[$name];
            }
        }
       //this method can user Yii::app()->user->{$user的attribute}
        return parent::__get($name);
    }

    public function login($identity, $duration) {
        $this->setState('__userInfo', $identity->getUser());
        parent::login($identity, $duration);
    }

    public function getIsGuest() {
        $customer = Yii::app()->session->get('customer');
        return $customer === null || $customer['id'] === null;
    }
}
?>

 记得设置一下这个类Yii::app()->user

<?php
'components'=>array(
    'user'=>array(
        'class'=>'WebUser',
    )
)
?> 

调用方法

Yii::app()->user->getIsGuest()

Yii::app()->user->__userInfo;

 

2用户信息存到单独的文件

<?php
class WebUser extends CWebUser
{
    public function getReturnUrl($defaultUrl=null)
    {   
        $userInfo = $this->getUserInfo();
        if(isset($userInfo['url'])){
            return $userInfo['url'];
        }
        return parent::getReturnUrl($defaultUrl);
    }

    protected function afterLogin($fromCookie)
    {
        parent::afterLogin($fromCookie);
        $users = require(dirname(__FILE__) . '/../config/password.php');

        $this->setState('userInfo',$users[$this->getName()]);
    }

    public function getUserInfo()
    {
        return $this->getState('userInfo',array());
    }
//accessRules  roles
    public function checkAccess($operation,$params=array(),$allowCaching=true)
    {
        $userInfo = $this->getUserInfo();
        if($userInfo['group'] == $operation){
            return true;
        }
        return parent::checkAccess($operation,$params,$allowCaching);
    }
}

 password.php

<?php

return array(
    'dianyin'           => array(
        'pwd'           => 'dianyinXX',
        'url'           => array('dianyin/order/index'),
        'merchant_id'   => 1,
        'group'         => 'dianyin',
     ),
    'boer' => array(
        'pwd'           => 'boerXX',
        'url'           =>  array('third_jifen/default/index'),
        'merchant_id'   => 1,
        'group'         => 'jifen',
    ),
);

 权限checkAccess结合roles

public function accessRules()
{
    return array(
        array('allow', // allow authenticated users to access all actions
            'roles'=>array('jifen'),
        ),
        array('allow',  // deny all users
            'actions'=>array('login','logout'),
            'users'=>array('*'),
        ),	
        array('deny',  // deny all users
            'users'=>array('*'),
        ),
    
    );
}
