Cakephp 2.4.5身份验证功能无法正常工作

Question

我是Cakephp的新手并尝试创建一个简单的用户注册和登录应用程序。编写代码后，我面临的问题是我的登录表单授权任何电子邮件和密码，并重定向到登录后设置的页面。 这是我的代码：

在 AppController.php

中

App::uses('Controller', 'Controller');
class AppController extends Controller 
{
var $components = array('Auth');                                                                      
}

在 UserController.php

中

<?php
//Filename  -UsersController.php

//Registering new users and login
class UsersController extends AppController
{

 public $helpers = array('Html','Form','Session');
 public $components = array('Session',
                        'Auth' => array(
                           'authenticate' => array(
                           'Form' => array (
                           'fields' => array('username'=>'email','password'=>'password')
 ))));

 /**
  *  Function for saving a new user
  */
  public function index()
  {
  if($this->request->is('post'))
  {
  //print_r($this->request->data);die;  
  $this->User->create();
  if($this->User->save($this->request->data))
  {
  $this->Session->setFlash(__('Congrats, you are registered successfully'));
  return $this->redirect(array('action'=>'index')); 
  } 
  $this->Session->setFlash(__('Unable to store the user'));
  } 
  }


  /**
   *  Function for login functionality
   */
   function beforeFilter()
{
 $this->Auth->loginRedirect=array('controller'=>'pages','action'=>'welcome');
 $this->Auth->logoutRedirect = array('controller'=>'pages','action'=>'welcome');
 }

 public function login()
 {
    if($this->request->is('post'))
    {
      if($this->Auth->login())
      {
        //print_r($this->request->data);die;
        $this->redirect($this->Auth->redirect());
      } 
      $this->Session->setFlash(__('Invalid username or password, try again'));
    }
 }

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

在模型 User.php

中

    <?php 
        // Filename - User.php
        // Model for registering new users
       App::uses('AppModel', 'Model');
       App::uses('SimplePasswordHasher', 'Controller/Component/Auth');
       class User extends AppModel
       {        
public $validate = array(
                        'username'=>array('required'=>array(
                        'rule'=>array('notEmpty'),                                                  
                        'message'=>'Username is required'
                                                           )),
                        'password'=>array('required'=>array(
                         'rule'=>array('notEmpty'),                                   
                         'message'=>'Password is required'
                                                           )),
                        'email'=>array('required'=>array(
                        'rule'=>array('notEmpty'),                                   
                        'message'=>'Email is required'
                                                        ))  
                        );
     public function beforeSave($options = array())
 {
     if(isset($this->data['User']['password']))
{
$passwordHasher = new SimplePasswordHasher();
$this->data['User']['password']=
    $passwordHasher->hash($this->data['User']['password']);
    }
    return true;
        }
       }

在 login.ctp

中

   <?php
         echo $this->Form->create();
         echo $this->Form->input('username',array('style'=>'width:200px;'));
         echo $this->Form->input('password',array('style'=>'width:200px;'));
         echo $this->Form->end('Sign in');
         ?>

请帮我解决这个问题。谢谢。

如果您想要一个简单的用户注册/登录应用程序，我建议您查看CakeDC Users Plugin。

Answer 2

首先在AppController上使用AuthComponents而不是在UsersController上。所以，你的代码 -

在AppController.php

中

App::uses('Controller', 'Controller');
 class AppController extends Controller 
 {
 public $helpers = array('Html','Form','Session');
 public $components = array('Session',
                        'Auth' => array(
                           'authenticate' => array(
                                'Form' => array (
                                    'fields' => array('username'=>'email','password'=>'password')
 ))));  


}

UsersController.php

从UsersController.php中删除public $helpers, public $components

在login.ctp

中

因此，您将默认username更改为email，因此请在视图上使用email。

   <?php
         echo $this->Form->create();
         echo $this->Form->input('email',array('style'=>'width:200px;'));
         echo $this->Form->input('password',array('style'=>'width:200px;'));
         echo $this->Form->end('Sign in');
         ?>
