登录功能在 cake php 中不起作用

我生成 UsersController.php

     public function login() {
        if ($this->Auth->login()) {
            $this->redirect($this->Auth->redirect());
        } else {
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
     }

     public function add() {
         if ($this->request->is('post')) {
        $this->User->create();
        $this->request->data['User']['password'] = md5($this->request->data['User']['password']);
        if ($this->User->save($this->request->data)) {
            $this->Session->setFlash(__('The user has been saved'));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The user could not be saved. Please, try again.'));
        }
     }
   }

我的模型文件 Users.php

            <?php 
            App::uses('AuthComponent', 'Controller/Component');

            class User extends AppModel {
                public $validate = array(
                    'username' => array(
                    'required' => array(
                        'rule' => array('notEmpty'),
                        'message' => 'A username is required'
                      )
                          ),
                         'password' => array(
                         'required' => array(
                            'rule' => array('notEmpty'),
                         'message' => 'A password is required'
                      )
                       ),
                     'role' => array(
                      'valid' => array(
                          'rule' => array('inList', array('admin', 'author')),
                                  'message' => 'Please enter a valid role',
                          'allowEmpty' => false
                       )
                      )
                  );

                   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;
                   }
               }
               ?>

我的视图文件是Uesrs/login.ctp

           <div class="users form">

               <?php echo $this->Session->flash('auth'); ?>
               <?php echo $this->Form->create('User'); ?>

              <fieldset>

                  <legend><?php echo __('Please enter your username and password'); ?></legend>
                  <?php echo $this->Form->input('username');
                     echo $this->Form->input('password');
                  ?>

               </fieldset>

              <?php echo $this->Form->end(__('Login')); ?>

           </div>

当我运行此代码时，它会告诉“无效的用户名或密码，请重试”。

但是我输入了正确的用户名和密码。

为什么会出现这个问题？

请帮我。我是 Cake Php 的新手。

试试这个。您确定用户名和密码吗？可以在数据库中再次检查吗？

   public function login()
      {
      if( $this->request->is('post') )
      {
        App::Import('Utility', 'Validation');
        if( isset($this->data['User']['username']) && Validation::email($this->data['User']['username']) )
        {
          $this->request->data['User']['email'] = $this->data['User']['username'];
          $this->Auth->authenticate['Form'] = array('fields' => array('username' => 'email'));
        }

        if( ! $this->Auth->login() )
        {
          $this->Session->setFlash(__('Invalid username or password, try again'));
        }
        else
        {
          $this->redirect($this->Auth->redirect());
        }
      }
    }
