无法登录cakephp 3.0.8

Question

当我尝试登录时说＆＃34;无效的电子邮件或密码，请再试一次＆＃34;。我使用了默认密码hasher而没有它也可以，但我得到的结果与两者相同。并且默认验证也不起作用。 登录代码。

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

验证代码。

// src/Model/Table/UsersTable.php
namespace App\Model\Table;

use Cake\ORM\Table;
use Cake\Validation\Validator;

class UsersTable extends Table
{

    public function validationDefault(Validator $validator)
    {
        return $validator
            ->notEmpty('email', 'A email is required')
            ->notEmpty('password', 'A password is required')
           ;
    }

}

如果有人需要更多信息，请告诉我。 提前谢谢。
