CakePHP 2.4 Auth-> login（）始终返回FALSE

Question

我正在为我的妈妈开发一个带有Cake 2.4的简单登录应用程序。 这是用户模型的代码。

App::uses('SimplePasswordHasher', 'Controller/Component/Auth');

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'
                        )
                )
        );

        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;
        }
}

我的UsersController代码是...

class UsersController extends AppController{
        public $helpers = array('Html','Form');

        public function beforeFilter(){
                parent::beforeFilter();
                $this->Auth->allow('add');
        }
        public function add(){
                if($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 login(){
                $this->layout = 'mlayout';
                if($this->request->is('post')){
                        debug($this->Auth->login());
                        var_dump($this->request->data);
                        if($this->Auth->login()){
                                $this->Session->setFlash('Logged In');
                                //return $this->redirect($this->Auth->redirectUrl());
                        }else{
                                $this->Session->setFlash(__('Usuario o Contraseña invalido, intentelo de nuevo.'));
                        }
                }
        }
        public function logout(){
                return $this->redirect($this->Auth->logout());
        }
}

AppController代码：

class AppController extends Controller{

        public $components = array('Session',
                'Auth' => array(
                        'loginRedirect' => array(
                                'controller' => 'homes',
                                'action' => 'index'
                        ),
                        'logoutRedirect' => array(
                                'controller' => 'homes',
                                'action' => 'index'
                        ),
                        'authorize' => 'controller'
                )
        );

        public function beforeFilter(){
                $this->Auth->allow('index','view','login');
        }
}

Login.ctp

<table id="formtable">
    <form id="UserForm" method="post" action="/mercadito/users/login">
        <tr>
        <td align="right">Login -> </td>
        <td><input type="text" name="username" style="width: 150px; height: 30px;"/></td>
        </tr>
        <tr>
        <td align="right">Contraseña -> </td>
        <td><input type="password" name="password" style="width: 150px; height: 30px;"/></td>
        </tr>
        <tr>
        <td></td>
        <td align="center"><input type="submit" value="ENTRAR" style="width: 100px; height: 30px;"/></td>
        </tr>
    </form>
</table>

debug($this->Auth->login()) returns: /app/Controller/UsersController.php (line 23) false

var_dump() returns: array(2) { ["username"]=> string(9) "admin" ["password"]=> string(9) "admin" }

每次都会发生这种情况。 我更改了allow->('login') ，然后检查密码是否正确地进行了哈希处理。 但是问题仍然存在。

Answer 1

您应该使用$ this-> Form-> input（）方法创建字段，因为Cake期望的字段应类似于：

data[User][username]
data[User][password]

因此，您的代码应类似于：

<?php echo $this->Form->create('User'); ?>
    <fieldset>
    <?php
        echo $this->Form->input('username');
        echo $this->Form->input('password');
    ?>
    <?php echo $this->Form->submit(__('Login'));?>
    </fieldset>
<?php echo $this->Form->end(); ?>

我敢打赌，如果您尝试使用空密码，它应该让您进入，因为它总是会加密空变量:)

Answer 2

尝试在您的组件中扩展Component-Variable

AppController的：

---

class AppController extends Controller{

    public $components = array('Session',
            'Auth' => array(
                'loginRedirect' => array(
                      'controller' => 'homes',
                      'action' => 'index'
                 ),
                 'logoutRedirect' => array(
                      'controller' => 'homes',
                      'action' => 'index'
                 ),
                 'authorize' => 'controller'
                 ),
                'Form' => array(
                    'passwordHasher' => array(
                        'className' => 'Simple',
                        'hashType' => 'sha256'
                )
            )
    );

Answer 3

确保在数据库中输入密码varchar(40)或varchar(40+)因为cakephp的哈希算法将生成36 characters字符串。

Answer 4

我不明白您为什么接受错误的答案。 由于您正尝试使用电子邮件地址进行身份验证，因此应在login.ctp中更改name属性，如下所示：

<input type="text" name="username" style="width: 150px; height: 30px;"/>

至

<input type="text" name="email" style="width: 150px; height: 30px;"/>

Answer 5

我遇到了同样的问题，为我解决的问题是将$ this-> alias更改为User，所以beforeSave（）现在看起来像

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