好的，这是场景：
- 管理员登录
- 管理员登出
- 普通用户登录
- 重定向到管理页面！
如果我在以普通用户身份登录之前删除存储的 cookie，登录将按预期工作。我注意到的另一件奇怪的事情是，当普通用户登录时，我的登录功能中的管理员重定向实际上并没有运行，因此它们被重定向到其他地方。
这是一些代码：
用户控制器：
<?php
public function login() {
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->Auth->login()) {
//if login successful update logged in User as login does not use recursive find
$this->User->id = $this->Auth->user('id');
$this->User->read();
$this->Auth->login($this->User->data);
if($this->Login->isRole($this->Auth->user(), 'Admin')) {
//redirect admins to admin page, not ran when error occurs!!
$this->redirect(array('controller' => 'users', 'action' => 'index', 'admin' => true));
} else {
//isAuthorised in AppController takes care of redirect to registration page if required
$this->redirect($this->Auth->redirect());
}
} else {
//if login unsuccessful
$this->Session->setFlash(
__('Invalid username or password, please try again.'),
'alert',
array(
'plugin' => 'TwitterBootstrap',
'class' => 'alert-error'
)
);
}
}
//set layout
$this->layout = 'not_logged_in';
//set title
$this->set('title_for_layout', 'Login');
}
public function logout() {
//logout
$this->redirect($this->Auth->logout());
}
public function isAuthorized($user) {
if(parent::isAuthorized($user)) {
//call parent method for redirect and admin permission
return true;
}
switch ($this->action) {
case 'add':
case 'resetPassword':
case 'login':
//logged in users cannot access registration, login or password reset pages
return false;
break;
case 'add_role':
//check user is finshing registration or has a role request accepted
return (!$this->Login->isRegistrationComplete($user) || $this->Login->isRoleRequestAccepted($user));
break;
default:
//all loogged in users can access the rest of User controller
return true;
break;
}
}
php?>
应用控制器：
<?php
public $components = array(
'Session',
'Auth' => array(
'className' => 'UserAuth',
'loginRedirect' => array('controller' => 'users', 'action' => 'view'),
'logoutRedirect' => array('controller' => 'users', 'action' => 'login'),
'authorize' => array('Controller'),
'authenticate' => array('Blowfish'),
'authError' => 'Please login.',
'loginError' => 'Invalid Username or Password entered, please try again.',
),
'Login'
);
public function isAuthorized($user) {
//set values needed for all logged in pages
$this->set('loggedIn', $user);
$this->set('role', $user['User']['role']);
if($this->Login->isAccessing($this, 'users', 'logout')) {
//never prevent user from logging out
return true;
}
if($this->Login->isRole($user, 'Admin')) {
//admin can access every action
return true;
} elseif ($this->request->prefix === 'admin') {
//only admins allowed on admin pages
throw new Exception('You do not have permission to access this page.', 1);
}
//get user role and requested role
$roles = $this->Login->getRolesCurrentAndNew($user);
if($this->Login->isRoleRequestAccepted($user)) {
//user has an accepted role request
$controller = 'users';
$action = 'add_role';
if($this->Login->isRedirectRequired($this, $controller, $action)) {
//if user is already accessing registration this check prevents redirect loops
if ($this->Login->isRegistrationComplete($user)) {
//display flash based on registration status
$this->Session->setFlash(
__('Your request for the role of '. strtolower($roles['new']) . ' has been accepted, please enter additional details.'),
'alert',
array(
'plugin' => 'TwitterBootstrap',
'class' => 'alert-success'
)
);
} else {
$this->Session->setFlash(
__('Please complete your registration.'),
'alert',
array(
'plugin' => 'TwitterBootstrap',
'class' => 'alert-success'
)
);
}
$this->redirect(array('controller' => $controller, 'action' => $action));
}
} elseif (!$this->Login->isRegistrationComplete($user)) {
//user has not registered yet and role request is not accepted
if(!$this->Login->isRegistrationComplete($user)) {
//user has not completed registration yet, awaiting approval
throw new Exception('Your registration request is awaiting approval from a member of the admin team.', 1);
}
}
return false;
}
?>
