How to extend Laravel's Auth Guard class?
提问by Holger Weis
I'm trying to extend Laravel's Auth Guardclass by one additional method, so I'm able to call Auth::myCustomMethod()at the end.
我正在尝试通过一种附加方法扩展 Laravel 的 Auth Guard类，因此我可以Auth::myCustomMethod()在最后调用。
Following the documentation section Extending The FrameworkI'm stuck on how to exactly do this because the Guard class itself doesn't have an own IoC bindingwhich I could override.
在文档部分扩展框架之后，我被困在如何准确地执行此操作上，因为 Guard 类本身没有我可以覆盖的自己的IoC 绑定。
Here is some code demonstrating what I'm trying to do:
这是一些代码，演示了我正在尝试做的事情：
namespace Foobar\Extensions\Auth;
class Guard extends \Illuminate\Auth\Guard {
public function myCustomMethod()
{
// ...
}
}
Now how should I register the extended class Foobar\Extensions\Auth\Guardto be used instead of the original Illuminate\Auth\Guardso I'm able to call Auth::myCustomMethod()the same way as e.g. Auth::check()?
现在我应该如何注册Foobar\Extensions\Auth\Guard要使用的扩展类而不是原始类，Illuminate\Auth\Guard以便我能够以Auth::myCustomMethod()与 eg 相同的方式调用Auth::check()？
One way would be to replace the Authalias in the app/config/app.phpbut I'm not sure if this is really the best way to solve this.
一种方法是替换中的Auth别名，app/config/app.php但我不确定这是否真的是解决此问题的最佳方法。
BTW: I'm using Laravel 4.1.
顺便说一句：我使用的是 Laravel 4.1。

I would create my own UserProvider service that contain the methods I want and then extend Auth.
我将创建自己的 UserProvider 服务，其中包含我想要的方法，然后扩展 Auth。
I recommend creating your own service provider, or straight up extending the Auth class in one of the start files (eg. start/global.php).
我建议创建您自己的服务提供者，或者直接在启动文件之一（例如start/global.php）中扩展 Auth 类。
Auth::extend('nonDescriptAuth', function()
{
return new Guard(
new NonDescriptUserProvider(),
App::make('session.store')
);
});
This is a good tutorial you can follow to get a better understanding
这是一个很好的教程，您可以遵循以更好地理解
There is another method you could use. It would involve extending one of the current providers such as Eloquent.
您可以使用另一种方法。它将涉及扩展当前的提供程序之一，例如 Eloquent。
class MyProvider extends Illuminate\Auth\EloquentUserProvider {
public function myCustomMethod()
{
// Does something 'Authy'
}
}
Then you could just extend auth as above but with your custom provider.
然后你可以像上面一样扩展身份验证，但使用你的自定义提供者。
\Auth::extend('nonDescriptAuth', function()
{
return new \Illuminate\Auth\Guard(
new MyProvider(
new \Illuminate\Hashing\BcryptHasher,
\Config::get('auth.model')
),
\App::make('session.store')
);
});
Once you've implemented the code you would change the driver in the auth.phpconfig file to use 'nonDescriptAuth`.
实现代码后，您将更改auth.php配置文件中的驱动程序以使用“nonDescriptAuth”。

Only way to add (and also replace existing functions) is to create copy of Guard.phpfile in your project and in app/start/global.phpadd:
添加（并替换现有函数）的唯一方法是在您的项目中创建Guard.php文件的副本，并在app/start/global.php添加：
require app_path().'/models/Guard.php';
Of course it's ugly method, but I spent over hour to test all possibilities [how to change things stored in Session by Auth] and it always end with error: ... _contruct of class HSGuard requires first parameter to be 'UserProviderInterface' and get 'EloquentUserProvider' ...
当然这是丑陋的方法，但我花了一个多小时来测试所有可能性[如何通过身份验证更改存储在会话中的内容]，它总是以错误结束：... HSGuard 类的 _contruct 需要第一个参数为“UserProviderInterface”并获取'EloquentUserProvider' ...
