如何使用CakePHP 2.x获取Auth组件拒绝访问的页面?如果我使用referer()函数,它会给我链接到被拒绝操作的页面。这是我的代码:

public function login() {
    //get the current url of the login page (or current controller+action)
    $currentLoginUrl = "/login";

    if ($this->request->is('post')) {

        $this->User->recursive = -1;            
        $user = $this->User->find(
            'first', 
            array(
                'conditions' => array(
                    'User.username' => $this->request->data['User']['username'], 
                    'User.password' => AuthComponent::password($this->request->data['User']['password'])
                )
            )
        );

        if ($user && $this->Auth->login($user['User'])) {                   
            //if the referer page is not from login page, 
            if( $this->referer() != $currentLoginUrl  )                 
            //use $this->referer() right away
            $this->redirect($this->referer('/admin', true));  //if referer can't be read, or if its not from local server, use $this->Auth->rediret() instead                   
            else
            //if the user lands on login page first, rely on our session 
            $this->redirect( $this->Session->read('beforeLogin_referer') );
        }
        else 
            $this->Session->setFlash('Username or password is incorrect', 'default', array('class' => 'alert-danger'));         
    }

    if( $this->referer() != $currentLoginUrl  )             
    //store this value to use once user is succussfully logged in
    $this->Session->write('beforeLogin_referer', $this->referer('/admin', true) ) ;  //if referer can't be read, or if its not from local server, use $this->Auth->rediret() instead                
}

所以基本上发生的事情是我没有登录,而且我在这个网址:

'http://localhost/hotelguide/hotels/view/17/'

然后点击一个链接,将我带到

'http://localhost/hotelguide/hotels/review/17/'

但是这需要用户登录,因此它会将我重定向到登录页面,当我调试referrer()时,它会给我这个:

'http://localhost/hotelguide/hotels/view/17/'

我做错了什么?

在CakePHP中使用Auth组件并尝试访问受限制的站点时,它会将您重定向到登录页面并将引用页面保存在会话中。会话密钥 Auth.redirect 包含您要查找的值 - 您尝试访问的页面。

查看AuthComponent的__unauthenticated()方法。它包括负责将会话值写入 Auth.redirect 的代码。如果您不想使用AuthComponent,您可以检查它在组件中的实现方式,并根据我提到的方法编写您自己的解决方案。

$ this-> referer()不会为您提供正确的推荐人网址。如果你想获得推荐人网址只需使用$ this->会话 - >读取('Auth.redirect');

您可以通过$ this-> Session-> read('Auth.redirect');

找到您要查找的确切网址 每次重新加载页面时,

$ this-> referer()值都会更新。
