Why is the CakePHP authentication component not hashing my password?

问题

I'm using CakePHP 1.2 with Auth and ACL components.

In my user register action, the password is coming in unhashed. Specifically, this expression:

if ($this->data['User']['password'] !=
    $this->Auth->password($this->data['User']['confirm_password']))

This is evaluating to true, even when I submit identical values for password and confirm_password. I know that password is unhashed because when I remove the call to Auth->password, the expression evaluates to false.

I expected the Auth module to automagically hash the password. What am I doing wrong?

Here is my view:

<?php
    echo $form->create('User', array('action' => 'register'));

    echo $form->input('email',
                      array('after' => $form->error(
                        'email_unique', 'This email is already registered.')));
    echo $form->input('password');
    echo $form->input('confirm_password', array('type' => 'password'));
    echo $form->end('Register');
?>

Here is my register action from the user controller:

function register(){
    if ($this->data) {
        if ($this->data['User']['password'] !=
            $this->Auth->password($this->data['User']['confirm_password'])) {

            $this->Session->setFlash(__('Password and Confirm Password must match.', true));
            $this->data['User']['password'] = '';
            $this->data['User']['confirm_password'] = '';
        }
        else{
            $this->User->create();
            if ($this->User->save($this->data)){
                $this->redirect(array('action' => 'index'), null, true);
            }
            else {
                $this->data['User']['password'] = '';
                $this->data['User']['confirm_password'] = '';
                $this->Session->setFlash(__('Some problem saving your information.', true));
            }
        }
    }
}

And here is my appController where I include the Auth and Acl modules:

class AppController extends Controller {
    var $components = array('Acl', 'Auth');

    function beforeFilter(){
        if (isset($this->Auth)) {
            $this->Auth->allow('display');
            $this->Auth->fields =
              array(
                'username' => 'email',
                'password' => 'password');
            $this->Auth->authorize = 'actions';
        }
    }
}

What am I doing wrong?

回答1:

CakePHP won't hash passwords unless username contains a submitted value. I'm replacing the username field with email. However, I remapped those fields by setting the Auth->fields array. However, I was doing that in the appController instead of userController. So moving this line:

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

out of appController into userController solved it.
Now the question becomes "Why can't I reset the Auth->fields in appController?"

回答2:

You're probably overriding AppController::beforeFilter() with your UsersController::beforeFilter().

To "fix" it, just put parent::beforeFilter() at the beginning of the function.

回答3:

You should hash password before saving to database. Place this function into your User model:

function beforeSave() {
  if(isset($this->data[$this->alias]['password']))
    $this->data[$this->alias]['password'] = Security::hash($this->data[$this->alias]['password'], null, true);
  return true;
}

And don't forget to put this in beforeFilter() to your users controller:

if(in_array($this->action, array('register'))) {
  $this->Auth->fields = array('username' => 'email', 'password' => 'wrongfield');
}

That means that password will NOT be hashed during registration process (in case of failed validation of register form).

回答4:

i think you are looking for

hashPasswords ($data)

look at these pages. They should point you in the right direction. You can also try changing your debugging level in the core config file. changing it from 0 (production) to 3 allows you to see you sql output. may be helpful.

Sorry i can't do anything but point you in the right direction. I'm new to cakephp.
