Question

我想使用用户名或电子邮件进行登录。所以我想动态更改Auth字段。

如何修改$ this-＆gt;像Cakehp 2那样的Auth字段？

在cakephp 2中你可以这样做：

$this->Auth->authenticate = array(
    'Form' => array(
        'fields' => array('username' => 'email', 'password' => 'password'),
    ),
);

我试图像这样更改身份验证，但它不起作用：

$this->Auth->config('authenticate', [
    'Form' => [
        'fields' => ['username' => 'email', 'password' => 'password']
    ]
]);

谢谢！

Answer 1

我找到了解决方案！

我认为用户名是alphaNumeric（字母和数字）。

请务必添加$this->Auth->constructAuthenticate();

AppController.php

use Cake\Controller\Controller;
use Cake\Event\Event;
use Cake\Core\Configure;

class AppController extends Controller
{
    public function initialize()
    {
        parent::initialize();
        $this->loadComponent('Flash');
        $this->loadComponent('Auth', [
            'loginRedirect' => [
                'controller' => 'Users',
                'action'     => 'index'
            ],
            'logoutRedirect' => [
                'controller' => 'Users',
                'action'     => 'login'
            ]
        ]);
    }
}

UsersController.php

use App\Controller\AppController;
use Cake\Validation\Validation;

class UsersController extends AppController
{
    public function login()
    {
        if ($this->request->is('post')) {

            if (Validation::email($this->request->data['username'])) {
                $this->Auth->config('authenticate', [
                    'Form' => [
                        'fields' => ['username' => 'email']
                    ]
                ]);
                $this->Auth->constructAuthenticate();
                $this->request->data['email'] = $this->request->data['username'];
                unset($this->request->data['username']);
            }

            $user = $this->Auth->identify();

            if ($user) {
                $this->Auth->setUser($user);
                return $this->redirect($this->Auth->redirectUrl());
            }

            $this->Flash->error(__('Invalid username or password, try again'));
        }
    }
}

login.ctp

<div class="form">
<?= $this->Flash->render('auth') ?>
<?= $this->Form->create() ?>
    <fieldset>
        <legend><?= __('Please enter your username and password') ?></legend>
        <?= $this->Form->input('username') ?>
        <?= $this->Form->input('password') ?>
    </fieldset>
<?= $this->Form->button(__('Login')); ?>
<?= $this->Form->end() ?>
</div>

Answer 2

使用用户名登录或通过电子邮件发送其完美作品，试试吧。

UsersController.php

if($this->request->is('post')){
    if(!filter_var($this->request->data['username'], FILTER_VALIDATE_EMAIL)===false){
        $this->Auth->config('authenticate', [
            'Form'=>['fields'=>['username'=>'email', 'password'=>'password']]
        ]);
        $this->Auth->constructAuthenticate();
        $this->request->data['email']=$this->request->data['username'];
        unset($this->request->data['username']);
    }
    pr($this->request->data);

    $user=$this->Auth->identify();
    if($user){
        $this->Auth->setUser($user);
        $this->Flash->success(__('Wel Come-'.ucfirst($user['name'])));
        return $this->redirect($this->Auth->redirectUrl());
    }
    $this->Flash->error(__('Invalid username or password, try again'));
}

Answer 3

这是我的解决方案。

AppController.php 加载Auth组件。

$this->loadComponent('Auth', [
        'authorize' => 'Controller',
        'authenticate' => [
            'Form' => [
                'userModel' => 'Users',
            ]
        ],
        ...
    ]);

UsersController.php

注意：identify（）方法

http://book.cakephp.org/3.0/en/controllers/components/authentication.html#identifying-users-and-logging-them-in

public function login()
{
    if ($this->request->is('post')) {
        //$user = $this->Auth->identify();
        $user = $this->Users->identify($this->request->data);
        if ($user) {
            $this->Auth->setUser($user);
            return $this->redirect($this->Auth->redirectUrl());
        } else {
            $this->Flash->error(__('Username or password is incorrect'), [
                'key' => 'auth'
            ]);
        }
    }
}

<强> UsersTable.php

假设电子邮件和用户名列位于同一个表格中。

use Cake\Auth\DefaultPasswordHasher;

public function identify($formData) {

        $passOk = false;
        $user = $this->find()->hydrate(false)->where(['email' => $formData['email']])->orWhere(['username' => $formData['email']])->first();
        $checker = new DefaultPasswordHasher;
        if(!is_null($passOk))
            $passOk = $checker->check($formData['password'], $user['password']); 

        return $passOk ? $user  : null;

    }

Answer 4

这是另一个有用的解决方案（也许）...

login.ctp

为了使您的生活更轻松，对于用户输入，只需使用用户名和密码

<?= $this->Form->create() ?>
     <div class="panel-body">
         <div class="form-group">
             <?= $this->Form->control('username', // <-- username input
               ['type' => 'text', 'class' => 'form-control', 'label' => false, 
                    'placeholder' => __('Username Or Email') ]) ?>
             <?= $this->Form->control('password',  // <-- password input
               ['class' => 'form-control', 'label' => false, 'placeholder' => 
                    __('Password')]) ?>
                        </div>
             <?= $this->Form->button('ログイン', ['class' => 'btn btn-primary btn-block']) ?>
     </div>
<?= $this->Form->end() ?>

UsersTable.php

在这里我们创建检查列（用户名或电子邮件）的地方。虽然，对于密码检查，它已由CakePHP处理，但无需在此处包含它。

use Cake\ORM\Query;  

public function findAuth(Query $query, array $options)
{
    $query->where([
            'OR' => [ //<-- we use OR operator for our SQL
                'username' => $options['username'], //<-- username column
                'email' => $options['username'] //<-- email column
            ]], [], true); // <-- true here means overwrite original query !IMPORTANT. 

    return $query;
}

AppController.php 加载身份验证组件。

public function initialize()
{
     parent::initialize();
     $this->loadComponent('Auth', [
            'authenticate' => [
                'Form' => [
                    'finder' => 'auth' //<-- here we call our findAuth methods
                ]
            ],
     ]);
}

仅此而已。快乐的编码。 ?

祝一切顺利！
