遵循 CakePHP 简单身份验证教程后尝试登录时身份验证失败

Question

我正在尝试this简单认证的Cake食谱教程。用户已成功创建，但当我尝试登录时，它不会对用户进行身份验证。相反，显示 "Invalid username/password" 错误。

我唯一改变的是我使用的是电子邮件地址而不是用户名。

这是 User.php 应用模型：

<?php
App::uses('AppModel', 'Model');
App::uses('BlowfishPasswordHasher', 'Controller/Component/Auth');

class User extends AppModel {
    public $validate = array(
        'email' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'An email 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'])) {
        $passwordHasher = new BlowfishPasswordHasher();
        $this->data[$this->alias]['password'] = $passwordHasher->hash(
            $this->data[$this->alias]['password']
        );
    }
    return true;
}
}
?>

这是用户控制器 (Userscontroller.php)

<?php
App::uses('AppController', 'Controller');

class UsersController extends AppController {

    // public function __construct($request = null, $response = null)
    // {
 //     parent::__construct($request, $response);
    // }

    public function beforeFilter() {
        parent::beforeFilter();
        $this->Auth->allow('add','logout');
    }

    public function index() {
        $this->User->recursive = 0;
        $this->set('users', $this->paginate());
    }

    public function view($id = null) {
        $this->User->id = $id;
        if (!$this->User->exists()) {
            throw new NotFoundException(__('Invalid user'));
        }
        $this->set('user', $this->User->read(null, $id));
    }

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

    public function edit($id = null) {
        $this->User->id = $id;
        if (!$this->User->exists()) {
            throw new NotFoundException(__('Invalid user'));
        }
        if ($this->request->is('post') || $this->request->is('put')) {
            if ($this->User->save($this->request->data)) {
                $this->Session->setFlash(__('The user has been saved'));
                return $this->redirect(array('action' => 'index'));
            }
            $this->Session->setFlash(
                __('The user could not be saved. Please, try again.')
            );
        } else {
            $this->request->data = $this->User->read(null, $id);
            unset($this->request->data['User']['password']);
        }
    }

    public function delete($id = null) {
        // Prior to 2.5 use
        // $this->request->onlyAllow('post');

        $this->request->allowMethod('post');

        $this->User->id = $id;
        if (!$this->User->exists()) {
            throw new NotFoundException(__('Invalid user'));
        }
        if ($this->User->delete()) {
            $this->Session->setFlash(__('User deleted'));
            return $this->redirect(array('action' => 'index'));
        }
        $this->Session->setFlash(__('User was not deleted'));
        return $this->redirect(array('action' => 'index'));
    }

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

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



}
?>

这是 login.ctp 视图：

<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('email');
        echo $this->Form->input('password');
    ?>
    </fieldset>
<?php echo $this->Form->end(__('Login')); ?>
</div>

这是Appcontroller.php

Answer 1

编辑您 Appcontroller.php 中的下一行，如下所述

 'Form' => array(
            'passwordHasher' => 'Blowfish',
            'fields' => array('username'=>'email', 'password'=>'password'),
        )
