我正在cakephp 4中工作。我已经为登录身份验证设置了模型（'Representatives'），但它正在使用另一个带有名称users的模型进行身份验证。我已经上传了AppController.php文件以及EmployeesController.php文件，我在其中定义了方法（action）。
在控制器/应用控制器. php中

class AppController extends Controller
 {
   public function initialize(): void
   {
    parent::initialize();

    $this->loadComponent('RequestHandler');
    $this->loadComponent('Flash');       
    $this->loadComponent('Auth', [
        "authenticate" => [
            "Form" => [
                "fields" => [
                    "username" => "email",
                    "password" => "password"
                ],
                "userModel" => "Representatives"
            ]
        ],
        "loginAction" => [
            "controller" => "Employees",
            "action" => "login"
        ],
        "loginRedirect" => [
            "controller" => "Employees",
            "action" => "home"
        ],
        "logoutRedirect" => [
            "controller" => "Employees",
            "action" => "login"
        ]
    ]);
}

在员工控制器中：

class EmployeesController extends AppController
  {
     public function initialize(): void
     {
      parent::initialize();
      $this->loadModel("Employees");
      $this->loadModel("Representatives");
      $this->loadComponent('Flash');
    }

public function login()
  {
    if ($this->request->is('post')) {
        $user = $this->Auth->identify();
        // echo "<pre>"; print_r($user); die; 
        if ($user) {
            $this->Auth->setUser($user);
            echo "<pre>"; print_r($user); exit(); 
            return $this->redirect($this->Auth->redirectUrl());
        } else {
            $this->Flash->error(__('Username or password is incorrect'));
        }
    }
    $this->viewBuilder()->setLayout('home');
    $this->set("title", "Login");
  }

在模型/实体/代表性. php中

<?php

namespace App\Model\Entity;

use Authentication\PasswordHasher\DefaultPasswordHasher;
use Cake\ORM\Entity;

class Representative extends Entity
 {
  protected $_accessible = [

    'id' => false,
    'name' => true,
    'role' => true,
    'email' => true,
    'password' => true,
    'phone' => true,
    'slug' => false
];

protected function _setPassword(string $password) : ?string
{
    if (strlen($password) > 0) {
        return (new DefaultPasswordHasher())->hash($password);
    }
}
}

在模型/表格/代表性表格. php中

<?php
 namespace App\Model\Table;

 use Cake\ORM\Table;
 use Cake\Utility\Text;
 use Cake\Event\EventInterface;

 class RepresentativesTable extends Table
 {
  public function initialize(array $config) :void
   {

    $this->setTable("newusers");

 }

  public function beforeSave(EventInterface $event, $entity, $options)
  {
    if ($entity->isNew()  && !$entity->slug) {
        $sluggedTitle = Text ::slug($entity->name);
        $entity->slug = substr($sluggedTitle, 0, 191);
    }
  }
 }
