PHP Yii ucenter discuz

如今很多网站都要整合论坛程序，而康盛的Discuz系列产品往往是首选。然后就有了整合用户的需要，康盛提供了Ucenter架构，方便对不同的应用程序进行单点登录整合。

进来我尝试将ucenter整合到Yii网站中，获得了成功，虽然登录同步程序不是很妥当，基本使用没有问题了。我将继续改进。下面说说步骤：

下载安装ucenter和discuz，我使用的是ucenter1.6和discuz7.2，由于7.2自带的uc_client是旧版本，所以需要覆盖一下1.6版本。

复制一份uc_client文件夹到 protected/vendors/下，然后建立一个ucenter.php文件，内容如下：

<?php
include dirname(__FILE__).'/../config/main.php';
include dirname(__FILE__).'/uc_client/client.php';

可以看到这里只是包含了两个文件。然后打开yii的主配置文件 protected/config/main.php，加入ucenter的一些全局变量的设置：

<?php
define('UC_CONNECT', 'mysql');				// 连接 UCenter 的方式: mysql/NULL, 默认为空时为 fscoketopen()
											// mysql 是直接连接的数据库, 为了效率, 建议采用 mysql
//数据库相关 (mysql 连接时, 并且没有设置 UC_DBLINK 时, 需要配置以下变量)
define('UC_DBHOST', 'localhost');			// UCenter 数据库主机
define('UC_DBUSER', 'root');				// UCenter 数据库用户名
define('UC_DBPW', '');					// UCenter 数据库密码
define('UC_DBNAME', '027xfbbs');				// UCenter 数据库名称
define('UC_DBCHARSET', 'utf8');				// UCenter 数据库字符集
define('UC_DBTABLEPRE', '027xfbbs.uc_');			// UCenter 数据库表前缀

//通信相关
define('UC_KEY', 'ebR4GhhpZB7e9Mhb');				// 与 UCenter 的通信密钥, 要与 UCenter 保持一致
define('UC_API', 'http://027xf.test/ucenter');	// UCenter 的 URL 地址, 在调用头像时依赖此常量
define('UC_CHARSET', 'utf8');				// UCenter 的字符集
define('UC_IP', '');					// UCenter 的 IP, 当 UC_CONNECT 为非 mysql 方式时, 并且当前应用服务器解析域名有问题时, 请设置此值
define('UC_APPID', 2);					// 当前应用的 ID

// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');

// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.
return array(
	'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',

.....

请根据你的情况修改上面的数据库名等设置。

实现同步注册，我采用的是定义了表单RegisterForm来处理用户的注册，下面是一个典型的注册表单及其验证和业务逻辑代码：

<?php

/**
 * LoginForm class.
 * LoginForm is the data structure for keeping
 * user login form data. It is used by the 'login' action of 'SiteController'.
 */
class RegisterForm extends CFormModel
{
	public $username;
	public $password;
	public $repassword;
	public $email;
	public $verifyCode;

	/**
	 * Declares the validation rules.
	 * The rules state that username and password are required,
	 * and password needs to be authenticated.
	 */
	public function rules()
	{
		return array(
			// username and password are required
			array('username, password, repassword, email, verifyCode', 'required'),
            array('username', 'length', 'max'=>20, 'min'=>5),
			// 用户名唯一性验证
			//array('username', 'unique','caseSensitive'=>false,'className'=>'user','message'=>'用户名"{value}"已经被注册，请更换'),
			array('username', 'checkname'),
			// 密码一致性验证
			array('repassword', 'compare', 'compareAttribute'=>'password','message'=>'两处输入的密码并不一致'),
			// 电子邮件验证
			array('email', 'email'),
			// 电子邮件唯一性
			//array('email', 'unique','caseSensitive'=>false,'className'=>'user','message'=>'电子邮件"{value}"已经被注册，请更换'),
			array('email', 'checkemail'),
			//array('birthday', 'match', 'pattern'=>'%^\d{4}(\-|\/|\.)\d{1,2}\1\d{1,2}$%', 'allowEmpty'=>true, 'message'=>'生日必须是年-月-日格式'),
			//array('mobile', 'length', 'max'=>11, 'min'=>11, 'tooLong'=>'手机号码错误','tooShort'=>'手机号码错误'),
            array('verifyCode', 'captcha', 'allowEmpty'=> false),
		);
	}

	public function checkname($attribute,$params)
	{
		//ucenter
		Yii::import('application.vendors.*');
		include_once 'ucenter.php';
		$flag = uc_user_checkname($this->username);
		
		switch($flag)
		{
			case -1:
            	$this->addError('username', '用户名不合法');
				break;
			case -2:
				$this->addError('username','包含不允许注册的词语');
				break;
			case -3:
			 	$this->addError('username','用户名已经存在');
				break;
		}
	}
	
	public function checkemail($attribute,$params)
	{
		//ucenter
		Yii::import('application.vendors.*');
		include_once 'ucenter.php';
		$flag = uc_user_checkemail($this->email);

		switch($flag)
		{
			case -4:
            	$this->addError('email', 'Email 格式有误');
				break;
			case -5:
				$this->addError('email','Email 不允许注册');
				break;
			case -6:
			 	$this->addError('email','该 Email 已经被注册');
				break;
		}
	}

	/**
	 * Declares attribute labels.
	 */
	public function attributeLabels()
	{
		return array(
            'username'=>'设定用户名',
            'password'=>'设定密码',
			'repassword'=>'再次输入密码',
		    'email'=>'电子邮件地址',
		    'mobile'=>'手机号码',
            'verifyCode'=>'验证码',
		);
	}

	/**
	 * 注册用户
	 * @return boolean whether register is successful
	 */
	public function register($uid)
	{
		//ucenter
		Yii::import('application.vendors.*');
		include_once 'ucenter.php';
		$uid = uc_user_register($this->username, $this->password, $this->email);
		if($uid>0)
		{
			$model = new user;
			$model->attributes = $_POST['RegisterForm'];
			$model->password = md5($_POST['RegisterForm']['password']);
			$model->id = $uid;
			
			return $model->save();
		}
	}
}

我们看看上面的代码，调用了uc_user_checkname和uc_user_checkemail完成了用户名和email的验证，然后调用了 uc_user_register将用户注册到ucenter，成功后，再注册到Yii应用。

实现用户登录，典型的Yii应用使用 CUserIdentity来实现登录，我们要做的就是继承它，实现自己的验证逻辑：

<?php

/**
 * UserIdentity represents the data needed to identity a user.
 * It contains the authentication method that checks if the provided
 * data can identity the user.
 */
class UserIdentity extends CUserIdentity
{   
    public $id;
	/**
	 * Authenticates a user.
	 * The example implementation makes sure if the username and password
	 * are both 'demo'.
	 * In practical applications, this should be changed to authenticate
	 * against some persistent user identity storage (e.g. database).
	 * @return boolean whether authentication succeeds.
	 */
	public function authenticate()
	{
		//ucenter
		Yii::import('application.vendors.*');
		include_once 'ucenter.php';
		list($uid, $username, $password, $email) = uc_user_login($this->username, $this->password);
		if($uid > 0)
		{
			$user = user::model()->findByPk($uid);
			
			if($user == null)//说明网站数据库中没有，而ucenter中有这个用户，添加用户
			{
				$user = new user;
				$user->username = $username;
				$user->password = md5($password);
				$user->email = $email;
				$user->id = $uid;
				$user->save();
				
				$user->refresh();
			}
			
            $this->username = $user->username;
            $this->id = $user->id;
			
            $user->last_login_time = $user->this_login_time;
            $user->this_login_time = time();
            $user->last_login_ip = $user->this_login_ip;
            $user->this_login_ip = Yii::app()->getRequest()->userHostAddress;
            $user->save(); 
	        
			$this->errorCode=self::ERROR_NONE;
		}
		elseif($uid == -1)
		{
			$this->errorCode=self::ERROR_USERNAME_INVALID;
		}
		elseif($uid == -2)
		{
			$this->errorCode=self::ERROR_PASSWORD_INVALID;
		}
	    
		return !$this->errorCode;
	}
    
    public function getId()
	{
		return $this->id;
	}
}

请根据自己的应用情况进行修改即可，这里我们不需要对Yii的用户登录做任何修改。

然后我们修改 SiteController/actionLogin 方法，将同步登录其他应用的js输出到浏览器：

/**
	 * Displays the login page
	 */
	public function actionLogin()
	{
		$model=new LoginForm;

		// if it is ajax validation request
		if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
		{
			echo CActiveForm::validate($model);
			Yii::app()->end();
		}

		// collect user input data
		if(isset($_POST['LoginForm']))
		{
			$model->attributes=$_POST['LoginForm'];
			// validate user input and redirect to the previous page if valid
			if($model->validate() && $model->login())
			{
				//ucenter
				Yii::import('application.vendors.*');
				include_once 'ucenter.php';
				$script = uc_user_synlogin(Yii::app()->user->id);
				$this->render('loginsuc', array(
					'script' => $script,
				));
				Yii::app()->end();
			}
		}
		// display the login form
		$this->render('login',array('model'=>$model));
	}

简单的loginsuc.php视图文件：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<?php 
$this->layout = 'none';
echo $script; 
?>
<script type="text/javascript">setTimeout('location.href="<?php echo Yii::app()->user->returnUrl ?>"',3000);</script>
登录成功，正在返回登录前页面...
</body>
</html>

继续修改 SiteController/actionLogout方法，实现同步退出：

/**
	 * Logs out the current user and redirect to homepage.
	 */
	public function actionLogout()
	{
		Yii::app()->user->logout();
		//ucenter
		Yii::import('application.vendors.*');
		include_once 'ucenter.php';
		$script = uc_user_synlogout();
		$this->render('logoutsuc', array(
			'script' => $script,
		));
		Yii::app()->end();
	}

简单的logoutsuc.php视图文件：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<?php 
$this->layout = 'none';
echo $script; 
?>
<script type="text/javascript">setTimeout('location.href="<?php echo Yii::app()->homeUrl ?>"',3000);</script>
退出成功，正在返回首页...
</body>
</html>

进行到这里，我们已经实现了整合ucenter的登录和注册了，这样ucenter中有的用户，可以登录到yii应用，yii应用也可以注册用户到ucenter了。但是这还没有完成，我们需要的是在discuz中用户登录时，也同步登录yii应用，退出亦然，那么我们需要实现 Yii应用的 api/uc.php 这个接口程序。由于我们要用到Yii的框架资源，所以我没有采用硬编码的方式实现这个接口，而是创建了一个UcApplication类完成这个任务，继续往下看。

首先建立 api/uc.php 入口文件，代码如下：

<?php
define('UC_CLIENT_VERSION', '1.6.0');
define('UC_CLIENT_RELEASE', '20110501');

define('API_DELETEUSER', 1);		//note 用户删除 API 接口开关
define('API_RENAMEUSER', 1);		//note 用户改名 API 接口开关
define('API_GETTAG', 1);		//note 获取标签 API 接口开关
define('API_SYNLOGIN', 1);		//note 同步登录 API 接口开关
define('API_SYNLOGOUT', 1);		//note 同步登出 API 接口开关
define('API_UPDATEPW', 1);		//note 更改用户密码 开关
define('API_UPDATEBADWORDS', 1);	//note 更新关键字列表 开关
define('API_UPDATEHOSTS', 1);		//note 更新域名解析缓存 开关
define('API_UPDATEAPPS', 1);		//note 更新应用列表 开关
define('API_UPDATECLIENT', 1);		//note 更新客户端缓存 开关
define('API_UPDATECREDIT', 1);		//note 更新用户积分 开关
define('API_GETCREDITSETTINGS', 1);	//note 向 UCenter 提供积分设置 开关
define('API_GETCREDIT', 1);		//note 获取用户的某项积分 开关
define('API_UPDATECREDITSETTINGS', 1);	//note 更新应用积分设置 开关

define('API_RETURN_SUCCEED', '1');
define('API_RETURN_FAILED', '-1');
define('API_RETURN_FORBIDDEN', '-2');

// change the following paths if necessary
$yii=dirname(__FILE__).'/../protected/yii-1.1.6/framework/yii.php';
$config=dirname(__FILE__).'/../protected/config/main.php';

// remove the following lines when in production mode
defined('YII_DEBUG') or define('YII_DEBUG',true);
// specify how many levels of call stack should be shown in each log message
defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',0);

require_once($yii);
require(dirname(__FILE__).'/../protected/components/UcApplication.php');
Yii::createApplication('UcApplication', $config)->run();

这里可以看到，这个脚本和标准的index.php是一样的，只是使用了不同的Application类。我们接着看这个类。

建立 protected/components/UcApplication.php类文件：

<?php
class UcApplication extends CWebApplication
{
	public $defaultController = 'Uc';
	
	private $route = '';
	
	protected function preinit()
	{
        $this->parseRequest();
    }
	
	private function parseRequest()
	{
		$_DCACHE = $get = $post = array();

		$code = @$_GET['code'];
		parse_str($this->_authcode($code, 'DECODE', UC_KEY), $get);
		if(MAGIC_QUOTES_GPC) {
			$get = $this->_stripslashes($get);
		}
		
		$timestamp = time();
		if($timestamp - $get['time'] > 3600) {
			//exit('Authracation has expiried');
		}
		if(empty($get)) {
			exit('Invalid Request');
		}
		$action = $get['action'];
		
		require_once 'xml.class.php';
		$post = xml_unserialize(file_get_contents('php://input'));
		Yii::log($get, 'debug');
		Yii::log($post, 'debug');
		$_GET = $get;
		$_POST = $post;
		
		$this->route = $this->defaultController .'/'. $action;
		
		if(!in_array($action, array('test', 'deleteuser', 'renameuser', 'gettag', 'synlogin', 'synlogout', 'updatepw', 'updatebadwords', 'updatehosts', 'updateapps', 'updateclient', 'updatecredit', 'getcreditsettings', 'updatecreditsettings'))) 
		{
			exit(API_RETURN_FAILED);
		}
	}
    
    public function processRequest()
	{
		$this->runController($this->route);
	}
	
	private function _authcode($string, $operation = 'DECODE', $key = '', $expiry = 0) {
		$ckey_length = 4;
	
		$key = md5($key ? $key : UC_KEY);
		$keya = md5(substr($key, 0, 16));
		$keyb = md5(substr($key, 16, 16));
		$keyc = $ckey_length ? ($operation == 'DECODE' ? substr($string, 0, $ckey_length): substr(md5(microtime()), -$ckey_length)) : '';
	
		$cryptkey = $keya.md5($keya.$keyc);
		$key_length = strlen($cryptkey);
	
		$string = $operation == 'DECODE' ? base64_decode(substr($string, $ckey_length)) : sprintf('%010d', $expiry ? $expiry + time() : 0).substr(md5($string.$keyb), 0, 16).$string;
		$string_length = strlen($string);
	
		$result = '';
		$box = range(0, 255);
	
		$rndkey = array();
		for($i = 0; $i <= 255; $i++) {
			$rndkey[$i] = ord($cryptkey[$i % $key_length]);
		}
	
		for($j = $i = 0; $i < 256; $i++) {
			$j = ($j + $box[$i] + $rndkey[$i]) % 256;
			$tmp = $box[$i];
			$box[$i] = $box[$j];
			$box[$j] = $tmp;
		}
	
		for($a = $j = $i = 0; $i < $string_length; $i++) {
			$a = ($a + 1) % 256;
			$j = ($j + $box[$a]) % 256;
			$tmp = $box[$a];
			$box[$a] = $box[$j];
			$box[$j] = $tmp;
			$result .= chr(ord($string[$i]) ^ ($box[($box[$a] + $box[$j]) % 256]));
		}
	
		if($operation == 'DECODE') {
			if((substr($result, 0, 10) == 0 || substr($result, 0, 10) - time() > 0) && substr($result, 10, 16) == substr(md5(substr($result, 26).$keyb), 0, 16)) {
				return substr($result, 26);
			} else {
					return '';
				}
		} else {
			return $keyc.str_replace('=', '', base64_encode($result));
		}
	
	}

	private function _stripslashes($string) {
		if(is_array($string)) {
			foreach($string as $key => $val) {
				$string[$key] = $this->_stripslashes($val);
			}
		} else {
			$string = stripslashes($string);
		}
		return $string;
	}
}

这里可以看到，主要逻辑是processRequest方法，实现了ucenter通知的解码、调用相应的控制器和动作实现操作。

然后建立 protected/controller/UcController.php文件，代码如下：

<?php
class UcController extends Controller
{
	private $appdir = '';
	
	protected function beforeAction(CAction $action)
	{
		$this->appdir = Yii::app()->basePath . '/vendors/';
		return parent::beforeAction($action);
	}
	
	public function actionTest() {
		echo API_RETURN_SUCCEED;
	}

	public function actionDeleteuser() {
		$uids = explode(',', str_replace("'", '', $_GET['ids']));
		!API_DELETEUSER && exit(API_RETURN_FORBIDDEN);
		
		$users = user::model()->findAllByPk($uids);
		foreach($users as $user)
		{
			$user->delete();
		}

		echo API_RETURN_SUCCEED;
	}

	public function actionRenameuser() {
		$uid = $_GET['uid'];
		$usernameold = $_GET['oldusername'];
		$usernamenew = $_GET['newusername'];
		if(!API_RENAMEUSER) {
			echo API_RETURN_FORBIDDEN;
		}
		
		$user = user::model()->findByPk($uid);
		if($user !== null)
		{
			$user->username = $usernamenew;
			if($user->save(false))
				echo API_RETURN_SUCCEED;
			else
				echo API_RETURN_FAILED;
		}
	}

	public function actionGettag() {
		$name = $_GET['id'];
		if(!API_GETTAG) {
			echo API_RETURN_FORBIDDEN;
		}
		
		$echo = array();
		echo $this->_serialize($return, 1);
	}

	public function actionSynlogin() {
		$uid = $_GET['uid'];
		$username = $_GET['username'];
		if(!API_SYNLOGIN) {
			echo API_RETURN_FORBIDDEN;
		}
		
		$identity=new UcUserIdentity($username);

		if($identity->authenticate())
		{
			Yii::app()->user->login($identity, 0);
		}

		header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');
		//$_SESSION[Yii::app()->user->stateKeyPrefix.'__id'] = $uid;
		//$_SESSION[Yii::app()->user->stateKeyPrefix.'__name'] = $username;
	}

	public function actionSynlogout() {
		if(!API_SYNLOGOUT) {
			echo API_RETURN_FORBIDDEN;
		}

		//note 同步登出 API 接口
		header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');
		Yii::app()->user->logout();
	}

	public function actionUpdatepw() {
		if(!API_UPDATEPW) {
			echo API_RETURN_FORBIDDEN;
		}
		$username = $_GET['username'];
		$password = $_GET['password'];
		
		$user = user::model()->findByAttributes(array('username'=>$username));
		if($user !== null)
		{
			$user->password = md5($password);
			if($user->save())
				echo API_RETURN_SUCCEED;
			else
				echo API_RETURN_FAILED;
		}
		else
			echo API_RETURN_FAILED;
	}

	public function actionUpdatebadwords() {
		if(!API_UPDATEBADWORDS) {
			echo API_RETURN_FORBIDDEN;
		}
		$cachefile = $this->appdir.'./uc_client/data/cache/badwords.php';
		$fp = fopen($cachefile, 'w');
		$data = array();
		if(is_array($_POST)) {
			foreach($_POST as $k => $v) {
				$data['findpattern'][$k] = $v['findpattern'];
				$data['replace'][$k] = $v['replacement'];
			}
		}
		$s = "<?php\r\n";
		$s .= '$_CACHE[\'badwords\'] = '.var_export($data, TRUE).";\r\n";
		fwrite($fp, $s);
		fclose($fp);

	}

	public function actionUpdatehosts() {
		if(!API_UPDATEHOSTS) {
			echo API_RETURN_FORBIDDEN;
		}
		$cachefile = $this->appdir.'./uc_client/data/cache/hosts.php';
		$fp = fopen($cachefile, 'w');
		$s = "<?php\r\n";
		$s .= '$_CACHE[\'hosts\'] = '.var_export($_POST, TRUE).";\r\n";
		fwrite($fp, $s);
		fclose($fp);
		echo API_RETURN_SUCCEED;
	}

	public function actionUpdateapps() {
		if(!API_UPDATEAPPS) {
			echo API_RETURN_FORBIDDEN;
		}
		$UC_API = $_POST['UC_API'];

		//note 写 app 缓存文件
		$cachefile = $this->appdir.'./uc_client/data/cache/apps.php';
		$fp = fopen($cachefile, 'w');
		$s = "<?php\r\n";
		$s .= '$_CACHE[\'apps\'] = '.var_export($_POST, TRUE).";\r\n";
		fwrite($fp, $s);
		fclose($fp);

		//note 写配置文件
		$config_file = Yii::app()->basePath.'./config/main.php';
		if(is_writeable($config_file)) {
			$configfile = trim(file_get_contents($config_file));
			$configfile = substr($configfile, -2) == '?>' ? substr($configfile, 0, -2) : $configfile;
			$configfile = preg_replace("/define\('UC_API',\s*'.*?'\);/i", "define('UC_API', '$UC_API');", $configfile);
			if($fp = @fopen($config_file, 'w')) {
				@fwrite($fp, trim($configfile));
				@fclose($fp);
			}
		}
	
		echo API_RETURN_SUCCEED;
	}

	public function actionUpdateclient() {
		if(!API_UPDATECLIENT) {
			echo API_RETURN_FORBIDDEN;
		}
		$cachefile = $this->appdir.'./uc_client/data/cache/settings.php';
		$fp = fopen($cachefile, 'w');
		$s = "<?php\r\n";
		$s .= '$_CACHE[\'settings\'] = '.var_export($_POST, TRUE).";\r\n";
		fwrite($fp, $s);
		fclose($fp);
		echo API_RETURN_SUCCEED;
	}

	public function actionUpdatecredit() {
		if(!API_UPDATECREDIT) {
			echo API_RETURN_FORBIDDEN;
		}
		$credit = $_GET['credit'];
		$amount = $_GET['amount'];
		$uid = $_GET['uid'];
		echo API_RETURN_SUCCEED;
	}

	public function actionGetcredit() {
		if(!API_GETCREDIT) {
			echo API_RETURN_FORBIDDEN;
		}
	}

	public function actionGetcreditsettings() {
		if(!API_GETCREDITSETTINGS) {
			echo API_RETURN_FORBIDDEN;
		}
		$credits = array();
		echo $this->_serialize($credits);
	}

	public function actionUpdatecreditsettings() {
		if(!API_UPDATECREDITSETTINGS) {
			echo API_RETURN_FORBIDDEN;
		}
		echo API_RETURN_SUCCEED;
	}
	
	private function _serialize($arr, $htmlon = 0) {
		if(!function_exists('xml_serialize')) {
			include_once 'xml.class.php';
		}
		echo xml_serialize($arr, $htmlon);
	}
}

上面用到了xml.class.php这个类文件，可以在uc_client/lib目录找到。
这里需要说明的是，actionSynlogin方法中，利用了我定义的特殊的UserIdentity来登录的，因为不需要提供密码。

再来看看最后一个类：

<?php

/**
 * UserIdentity represents the data needed to identity a user.
 * It contains the authentication method that checks if the provided

可以看到，在这个认证类中，实现了对yii应用中没有的用户的建立操作。然后不需要对yii应用做任何特殊设置，就可以实现api接口了。

然后我们在ucenter中添加yii应用的设置，修改main.php中的相应设置，应该就可以实现ucenter的同步登录、注册、退出、删除用户、修改用户名等等功能了！这个实现方法相对很Yii，呵呵。

有什么问题，欢迎评论，和我联系。大家一起进步吧！

PS: 需要注意的是，整合了ucenter的Yii应用在部署时，需将 protected/vendors/uc_client/data/及其子目录、文件设为可写。否则将会有些奇怪的问题。
