CakePHP - 如何允许未经身份验证的访问特定页面 [英] CakePHP - How to allow unauthenticated access to specific pages

问题描述

我创建了一个CakePHP应用程序，其中我创建了一个 UsersController ，它处理所有关于用户。
当我尝试浏览 www.mydomain.com 时，如果我已经登录，它让我看到索引（ app / View /Pages/home.ctp ）。否则，它会将我重定向到 mydomain.com/users/login ，并且仍然登录。

查看 AppController.php ， PagesController.php 或 app / Config / core.php 和 app / Config / routes.php ，但没有找到任何东西。

我不记得了，我也没有记住。找不到如何禁用这个。

编辑：我的CakePHP版本是2.3。

解决方案

一般来说，您可以使用 auth components allow（） method 。

因为 PagesController 在一个操作（ display（））中处理所有页面，所以需要多做一些工作， ）。如果是这样，那么您可以使用 request-> params ['pass'] [0] ，它将保存页面名称，页面，然后使用 Auth :: allow 允许显示操作。

例如，在 PagesController 中：

  beforeFilter（）
 {
 parent :: beforeFilter（）; 
 
 $ allowedPages = array（'home'，'foo'，'bar'）; 
 if（isset（$ this-> request-> params ['pass'] [0]）&& 
 in_array（$ this-> request-> params ['pass '] [0]，$ allowedPages））
 {
 $ this-> Auth-> allow（'display'）; 
} 
} 
  

这将允许页 home ， foo 和 bar

如果您想将所有网页设为公开，那么您只需使用 Auth :: allow 没有任何条件，即：

  public function beforeFilter（）
 {
 parent :: beforeFilter ）; 
 $ this-> Auth-> allow（'display'）; 
} 
  

I have created a CakePHP app where I have created a UsersController, which handles all about users. When I try to browse www.mydomain.com, if I am logged in, it let's me see the index (app/View/Pages/home.ctp). Else, it redirects me to mydomain.com/users/login and persists to log in.

I have tried looking at AppController.php, PagesController.php or app/Config/core.php and app/Config/routes.php, but did not find anything. My UsersController.php, also, is not responsible for that, I think.

I do not remember and I cannot find how to disable this. Which file should be responsible for that?

EDIT:my CakePHP version is 2.3.

解决方案

Generally you can make specific actions public using the auth components allow() method.

Making pages public may require a little more work in case you'd want to make only specific pages public, since the PagesController handles all pages in a single action (display()). If that is the case, then you could utilize request->params['pass'][0] which will hold the page name, test this against a list of allowed pages, and then allow the display action using Auth::allow.

Example, in the PagesController:

public function beforeFilter()
{
    parent::beforeFilter();

    $allowedPages = array('home', 'foo', 'bar');
    if(isset($this->request->params['pass'][0]) &&
       in_array($this->request->params['pass'][0], $allowedPages))
    {
        $this->Auth->allow('display');
    }
}

This would allow the pages home, foo and bar to be viewed without being logged in.

If you'd wanted to make all pages public, then you could simply use Auth::allow without any conditions, ie:

public function beforeFilter()
{
    parent::beforeFilter();
    $this->Auth->allow('display');
}
