由于您的需求听起来与AuthComponent原本打算的设计，你有两个选择。

Since your needs sound outwith AuthComponent's originally intended design you have two options.

首先，如果它真的不符合你的需求，你可以创建和维护非常自己的AuthComponent。通过将 /cake/libs/controller/components/auth.php 复制到 /app/controller/components/auth.php 。

Firstly, if it really doesn't fit your needs, you could create and maintain your very own AuthComponent. Do this by copying /cake/libs/controller/components/auth.php to /app/controller/components/auth.php.

这将允许您完全重写组件，但缺点是，当您升级蛋糕时，您不会再收到AuthComponent的更新。

This would allow you to rewrite the component completely, but the downside is you will no longer receive updates to AuthComponent when you upgrade cake.

其次，您可以使用以下模式扩展CakePHP中的任何内容：

Secondly, you can extend just about anything in CakePHP using the following pattern:

// save as: /app/controllers/components/app_auth.php
App::import('Component', 'Auth');
class AppAuthComponent extends AuthComponent {
    function identify($user = null, $conditions = null) {
        // do stuff
        return parent::indentify($user, $conditions);
    }
}

..并替换 AppAuthComponent 。

如果您想添加更多的方法参数，请将它们放在API之后，例如：

• You only need to define the methods you wish to replace.
• You can run methods from the original AuthComponent (even ones you have redefined) at any point during your methods using parent::...
• The method arguments should remain in the same order as the original API for consistency.

• If you wish to add more method arguments, put them after the API ones, eg:

function identify（$ user = null，$ conditions = null，$ custom = array（））{...}

这种方法允许您进行应用程序特定的自定义，同时仍然使用核心中定义的最新方法。

This approach allows you to make application-specific customisation while still using the latest methods defined in the core where necessary.
