Yii-模块－后台登录实现方法

设置控制器，登录页面方法，退出方法 admin/user/login, logout..

/**
 *登录页面
 */
public function actionAdminLogin()
{
	$model = new User;
	// if it is ajax validation request
/*	if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
	{
		echo CActiveForm::validate($model);
		Yii::app()->end();
	}*/
		
	// collect user input data
	if(isset($_POST['User']))
	{
		$model->attributes=$_POST['User'];
		// validate user input and redirect to the previous page if valid
		if($model->validate() && $model->Adminlogin())
			$this->redirect(Yii::app()->user->returnUrl);
	}
	// display the login form
	//$this->render('login',array('model'=>$model));
	$this->render('login',array(
		'model'=>$model,
	));
}

/**
 * 退出
 */
public function actionAdminLogout()
{
	Yii::app()->user->logout();
	$this->redirect(Yii::app()->homeUrl."?r=admin");
}

设置模块，设置密码验证，登录函数，

/**
*验证密码
*parm $passord 用户输入的密码
*return 匹配成为返回为TRUE，否则为FALSE
*/
public function validatapassword($password)
{
	return $this->encrytp($password)===$this->password;
}

/**
* 加密
*/
private function encrytp($password,$pre="yiiapp"){
	return md5($pre.$password);
}

public function beforeSave()
{
	if(parent::beforeSave()){
		if($this->isNewRecord){
			$this->password = $this->encrytp($this->password);
		}
		return true;
	}else{
		return false;
	}
}

public $username;
public $password;
public $rememberMe;
public $verifyCode; 
private $_identity;
/**

**/登录方法
public function Adminlogin()
{
	
	if($this->_identity===null)
	{
		$this->_identity=new AdminIdentity($this->username,$this->password);
		$this->_identity->authenticate();
	}
	if($this->_identity->errorCode===AdminIdentity::ERROR_NONE)
	{
		$duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
		Yii::app()->user->login($this->_identity,$duration);//echo "fas";
		return true;
	}
	else
		return false;
}

配置密码验证模块。复制protected/components/UserIdentily.php->AdminIdentily.php

class AdminIdentity extends CUserIdentity
{
	private $_id;

	public function authenticate()
	{
		$username = strToLower($this->username);	
		$user = User::model()->find('LOWER(username)=?',array($username));
		if($user===null){
			$this->errorCode=self::ERROR_USERNAME_INVALID;
		}elseif(!$user->validatapassword($this->password)){
			$this->errorCode=self::ERROR_PASSWORD_INVALID;
		}else{
			$this->_id = $user->id;
			$this->username = $user->username;
			$this->errorCode=self::ERROR_NONE;
		}
		return !$this->errorCode;
	}
	
	public function getid()
	{
		return $this->_id;
	}
	 
	public function getPersistentStates()
	{
		return 'admin';
	}
}

修改布局文件链接

array('label'=>'登录', 'url'=>array('/admin/user/adminlogin'), 'visible'=>!Yii::app()->user->getstate('manage')==='admin'),
array('label'=>'退出 ('.Yii::app()->user->name.')', 'url'=>array('/admin/user/adminlogout'), 'visible'=>Yii::app()->user->getstate('manage')==='admin')

module文件配置登录页面，登录跳转页面

class AdminIdentity extends CUserIdentity
{
	private $_id;

	public function authenticate()
	{
		$username = strToLower($this->username);	
		$user = User::model()->find('LOWER(username)=?',array($username));
		if($user===null){
			$this->errorCode=self::ERROR_USERNAME_INVALID;
		}elseif(!$user->validatapassword($this->password)){
			$this->errorCode=self::ERROR_PASSWORD_INVALID;
		}else{
			$this->_id = $user->id;
			$this->username = $user->username;
			$this->errorCode=self::ERROR_NONE;
		}
		return !$this->errorCode;
	}
	
	public function getid()
	{
		return $this->_id;
	}
	 
	public function getPersistentStates()
	{
		return array('manage'=>'admin');
	}
}
