在我的应用程序中进行登录功能时，我发现了一个无法解决的问题…
我在IndexController中创建了login()动作，我正在尝试验证给定的数据。主要问题是，我不能将它们与用户模型连接，其中包含登录所需的所有数据，例如昵称(用户名)和密码。代码如下:
IndexController.php
App::uses('AppController', 'Controller');
App::import('Controller', 'Users');
class IndexController extends AppController{
public $helpers = array('Html','Form', 'Session');
public $uses = array('User', 'Registration');
public function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow();
}
public function index(){
$menu = $this->menu();
$this->set('menu', $menu);
}
public function login(){
if ($this->request->is('post')) {
$this->Auth->authenticate = array('Form' => array('userModel' => 'User' ));
var_dump($this->Auth->login());
exit();
if ($this->Auth->login($this->request->data)) {
return $this->redirect($this->Auth->redirectUrl());
}else{
$this->Session->setFlash(__('Invalid username or password, try again'));
$this->redirect(array('controller' => 'index', 'action' => 'login'));
}
if ($this->Session->read('Auth.User')) {
$this->Session->setFlash('You are logged in!');
return $this->redirect(array('controller' => 'index', 'action' => 'index'));
}
}
}
User.php
App::uses('AppModel', 'Model');
App::uses('SimplePasswordHasher', 'Controller/Component/Auth');
class User extends AppModel {
public $displayField = 'name';
//public $belongsTo = array('Role');
//public $actsAs = array('Acl' => array('type' => 'requester'));
public $validate = array(
'name' => array(
'maxLength' => array(
'rule' => array('maxLength', 20),
'message' => 'Name field is too long'
)
),
'nickname' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Field cannot be empty'
),
'maxLength' => array(
'rule' => array('maxLength', 20),
'message' => 'Nickname field is too long'
),
),
'password' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Field cannot be empty',
),
),
'role_id' => array(
'numeric' => array(
'rule' => array('numeric')
),
),
'email' => array(
'email' => array(
'rule' => array('email'),
'message' => 'Wrong email address format'
),
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Field cannot be empty',
),
'maxLength' => array(
'rule' => array('maxLength', 30),
'message' => 'Your custom message here'
),
),
'avatar' => array(
'maxLength' => array(
'rule' => array('maxLength', 50),
),
),
'points' => array(
'numeric' => array(
'rule' => array('numeric'),
),
),
);
public function beforeSave($options = array()) {
if (isset($this->data[$this->alias]['password'])) {
$passwordHasher = new SimplePasswordHasher();
$this->data[$this->alias]['password'] = $passwordHasher->hash(
$this->data[$this->alias]['password']
);
}
return true;
}
}
和UserController.php
App::uses('AppController', 'Controller');
class UsersController extends AppController {
public $helpers = array('Html', 'Form', 'Session', 'Paginator');
public $components = array('Auth', 'Session');
public function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow('');
}
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, $id));
}
public function edit($id = null){
$this->User->id = $id;
if (!$this->User->exists()) {
throw new NotFoundException(__('Invalid user'));
}
if ($this->request->is('post','put')) {
if ($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']);
}
$roles = $this->User->Role->find('list');
$this->set(compact('roles'));
}
public function add(){
if($this->request->is('post')){
$this->User->create();
if($this->User->save($this->request->data)){
$this->Session->setFlash('User has been registered');
return $this->redirect(array('controller' => 'index', 'action' => 'index'));
}
$this->Session->setFlash('Unable to register now, try again');
}
$roles = $this->User->Role->find('list');
$this->set(compact('roles'));
}
public function delete($id = null) {
$this->request->onlyAllow('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() {
}
}
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('User.nickname');
echo $this->Form->input('User.password');
?>
</fieldset>
<?php echo $this->Form->end(__('Login')); ?>
</div>
这里有一个问题:有可能让它变成那样吗?
编辑对不起，我忘了添加我在AppController中设置的所有Auth规则:
AppController.php
App::uses('Controller', 'Controller');
class AppController extends Controller {
public $components = array(
'Session',
'Acl',
'Auth' => array(
'authorize' => array(
'Actions' => array('actionPath' => 'controllers')
),
'authenticate' => array(
'Form' => array('username' => 'nickname'),
'Basic'
),
'loginAction' => array(
'controller' => 'index',
'action' => 'login'
),
'loginRedirect' => array(
'controller' => 'users',
'action' => 'index'
),
'logoutRedirect' => array(
'controller' => 'index',
'action' => 'index',
)
)
);
}
首先这一行绝对是错误的:
echo $this->Form->input('Userpassword');
改为
echo $this->Form->input('password');
also Cakes Auth默认情况下正在寻找名为"username"的字段，因此您有2个选项而不是User。昵称使用
echo $this->Form->input('username');
(并记住将验证从昵称更改为用户名)或
为$components数组中的auth用户配置不同的字段和用户名:在$components array
中传递设置public $components = array(
'Auth' => array(
'authenticate' => array(
'Form' => array(
'fields' => array('username' => 'nickname')
)
)
)
);
我强烈建议你阅读Cake的Auth组件，这样你就可以避免这样的错误。
