CakePHP-登录函数的问题

这是密码

userscoontroller.php

<?php

class UsersController extends AppController
{
    public function login()
    {
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                return $this->redirect($this->Auth->redirect());
            }
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
    }

    public function logout()
    {
        return $this->redirect($this->Auth->logout());
    }
}

?>

<?php

class User extends AppModel
{

    public function beforeSave($options = array())
    {
        if (isset($this->data[$this->alias]['password'])) {
            $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
        }

        return true;
    }
}

<?php

class AppController extends Controller
{
    public $components = array(
        'DebugKit.Toolbar',
        'Session',
        'Auth' => array(
            'loginRedirect' => array(
                'controller' => 'books',
                'action' => 'view'
            ),
            'logoutRedirect' => array(
                'controller' => 'pages',
                'action' => 'home'
            ),
        )
    );
}

login.ctp

（查看文件）

表名：用户

我是CakePHP新手，我刚刚编写了简单登录操作的代码，
当我尝试使用正确的凭据登录时，它总是显示不正确的用户名和密码

$this->Auth->login（）。请给我一个解决办法。谢谢。你应该试试这个

在CakePHP数据库中，表名应该是复数。模型名称应为带CamelCase的单数名词。控制器应为复数形式，且必须添加CamelCase add后缀控制器。视图文件夹名称始终与控制器复数名称相同（无后缀），且
。ctp
文件名应为动词

AppController.php

<?php
class AppController extends Controller {

    public $components = array(
        'RequestHandler','Session',
        'Auth' => array(
            'Autoredirect'=>false,
            'loginRedirect' => array('controller' => 'books', 'action' => 'view'),
            'logoutRedirect' => array('controller' => 'pages', 'action' => 'home'),
            'authError' => 'Did you really think you are allowed to see that?',
        )
    );
}    
?>

<?php

    var $helpers = array('Html', 'Form','Js','Session');
        public $components = array(

            'Session'
    );

        if ($this->request->is('post')) {

                 $this->Session->setFlash('You are successfully login','default',array('class'=>'alert alert-success'));  
                 return $this->redirect($this->Auth->redirect());
            }

User.php（用户模型）


我意外地限制了数据库中的密码字段，使密码部分存储在数据库中，这是导致此问题的原因。
您是否正在实施密码哈希器？谢谢您的回答，但它不再有效同一问题：(
 App::uses('SimplePasswordHasher', 'Controller/Component/Auth');
    class AppModel extends Model {
        public $components = array(
        'Auth' => array(

                'Form' => array(
                    'passwordHasher' => array(
                        'className' => 'Simple',
                        'hashType' => 'sha1'
