不能得到验证登录使用CakePHP 2.0工作 [英] Can't get Auth login to work with CakePHP 2.0

问题描述

我试图让一个简单的登录表单使用CakePHP 2.0 ... ...只是验证，没有ACL现在的工作。

I'm trying to get a simple login form to work using CakePHP 2.0... just Auth, no ACLs for now.

我能看到的形式，并输入电子邮件地址和密码，因为它们是在数据库中，但我只是得到返回的形式和显示闪光的错误消息。这里是我的code：

I'm able to see the form and enter the email and password as they are in the database, but I just get returned to the form and the flash error message is displayed. Here is my code:

AppController的：

 class AppController extends Controller
 {
     function beforeFilter()
     {
         $this->Auth->userModel = 'Users';
         $this->Auth->fields = array('username' => 'email', 'password' => 'password'); //have to put both, even if we're just changing one
         $this->Auth->loginAction = array('controller' => 'users', 'action' => 'login');
         $this->Auth->loginRedirect = array('controller' => 'hotels', 'action' => 'dashboard');
         $this->Auth->logoutRedirect = array('controller' => 'users', 'action' => 'login');
     }
 }

login.ctp：

<?php
         echo $this->Form->create('User', array('action' => 'login'));
         echo $this->Form->input('email');
         echo $this->Form->input('password');
         echo $this->Form->end('Login');
     ?>

UsersController：
     

 class UsersController extends AppController
 {
     var $name = 'Users';
     var $helpers = array('Html','Form');
     var $components = array('Auth','Session');

     function beforeFilter()
     {
         $this->Auth->allow("logout");
         parent::beforeFilter();
     }

     function index() { } //Redirects to login()

     function login()
     {
         if ($this->Auth->login())
         {
             $this->redirect($this->Auth->redirect());
         } else
         {
             $this->Session->setFlash(__('Invalid username or password, try again'));
         }
     }

     function logout()
     {
         $this->redirect($this->Auth->logout());
     }
 }
 ?>

我AP preciate任何帮助。谢谢！

I appreciate any help with this. Thanks!

推荐答案

的无效的用户名或密码，请重试的显示错误你打登录之后？

The "Invalid username or password, try again" error is displayed after you hit login?

有你应该检查几件事情：

There are a few things you should check:

•是输出 $这个 - ＆GT; Auth-＆GT;登录（）等同于数据库中的信息？把调试（$这个 - ＆GT; Auth-＆GT;登录（））。来查看输出在您的登录方式提交表单后

• Is the output of $this->Auth->login() identical to the information in your database? Put debug($this->Auth->login()) to see the output in your login method after the form is submitted.

•在数据库中正确地散列密码？

• Are the passwords correctly hashed in the database?

•尝试使 AuthComponent 适用于所有的控制器不只是 UsersController 。

• Try making the AuthComponent available to all your controllers not just the UsersController.

•不知道这是否有差别，但拨打父:: beforeFilter（）; 中的任何事情之前控制器的 beforeFilter 方法。

• Not sure if this makes a difference, but call parent::beforeFilter(); before anything else in your controller's beforeFilter method.

编辑：

时看到你试图基于电子邮件地址和密码进行验证。作为默认AuthComponent需要一个用户名和密码。你必须明确说明您想要的电子邮件地址和密码通过 $这个 - ＆GT予以审定; Auth-＆GT;登录（）。这个来自2.0文档：

Is see that you're trying to validate based on email and password. As a default AuthComponent expects a username and password. You have to explicitly state that you want the email and password to be validated by $this->Auth->login(). This comes from the 2.0 documentation:

public $components = array(
    'Auth'=> array(
        'authenticate' => array(
            'Form' => array(
                'fields' => array('username' => 'email')
            )
        )
    )
);

这是你没有看到任何SQL输出的其实是可以预料的，我相信。

The fact that you're not seeing any SQL output is to be expected, I believe.
