Cookie 在 CakePHP 中不工作，CookieComponent 不工作

Question

这是我的 AdminsController class，我在其中包含了 Cookie 组件，并使用了下面 #1 中给出的 cookie 创建代码。 #2 是我在我看来使用的代码。

每当我启动 url 时，它都会显示错误："Helper class CookieHelper could not be found."。

为什么会显示此错误，因为我曾要求使用 CookieComponent 设置和获取 cookie 的值。我遵循了他们在其网站上提供的 CakePHP 文档中的说明和代码语法。我在设置和获取 cookie 时真的遇到了麻烦。我需要这方面的帮助。我使用的 CakePHP 版本是 2.6.

#1 - 控制器：

class AdminsController extends AppController {

/**
 * This controller does not use a model
 *
 * @var array
 */
    //public $uses = array('Admin');


/**
 * Displays a view
 *
 * @return void
 * @throws NotFoundException When the view file could not be found
 *  or MissingViewException in debug mode.
 */
    public $components = array('Cookie');

    public function index() {


            $this->layout=false;
            //echo "=users index====";

            //$this->layout = 'adminlayout';


            if($this->request->is('post'))
            {
                        $username = $this->request->data['Admin']['username'];
                        $password = $this->request->data['Admin']['password'];
                        $remember_me = $this->request->data['Admin']['remember_me'];



                        $sql = $this->Admin->find('count',array(
                                    'conditions' => array('Admin.username'=>$username,'Admin.password'=>md5($password))
                                ));

                        //$this->Session->write('is_admin_login','Y');

                        if($sql>0)
                        {

                            $this->Session->write('is_admin_login','Y');
                            if(!empty($remember_me))
                            {
                                //*** set cookie starts

                                if($this->Cookie->check('username_cookie'))
                                {
                                    $this->Cookie->delete('username_cookie');
                                    $this->Cookie->write('username_cookie', $username, false, '30 Days');
                                }

                                if($this->Cookie->check('password_cookie'))
                                {
                                    $this->Cookie->delete('password_cookie');
                                    $this->Cookie->write('password_cookie', $password, false, '30 Days');
                                }   


                                //*** set cookie ends

                            }
                            else
                            {
                                if($this->Cookie->check('username_cookie'))
                                {
                                    $this->Cookie->delete('username_cookie');

                                }

                                if($this->Cookie->check('password_cookie'))
                                {
                                    $this->Cookie->delete('password_cookie');

                                }   

                            }


                            $this->redirect('/admin/home');
                        }
                        else
                        {
                            $this->Session->setFlash('Invalid username or password','default',array('class'=>'error_msg'));
                        }

            }


            $this->render('admin_login');
    }

Answer 1

您正在尝试在视图中使用组件，这就是为什么它告诉您没有名为 Cookie 的助手 class。

在您的 Controller 操作中使用 Cookie 组件设置一个变量，然后在您的视图中使用该变量：

从您的视图中删除这些行：

$this->Cookie->check('username_cookie')
$this->Cookie->check('password_cookie')

在您的控制器操作中使用它们来设置视图变量...类似于：

$this->set('username_cookie', $this->Cookie->read('username_cookie'));
$this->set('password_cookie', $this->Cookie->read('password_cookie'));

那么您就可以在您的视图中使用设置的变量了：

if(!empty($username_cookie)) {
    //do something
}

//or

if(!empty($password_cookie)) {
    //do something
}
