Kohana 3 get current controller/action/arguments
提问by n00b
In Kohana 2 you could easily get that information like this:
在 Kohana 2 中，您可以轻松获得如下信息：
echo router::$controller;
echo router::$method;
echo router::$arguments[0-x];
Any idea how that works in Kohana 3?
知道它在 Kohana 3 中是如何工作的吗？
Thanks in advance!
提前致谢！

From inside a controller:
从控制器内部：
$this->request->controller
$this->request->controller
$this->request->action
$this->request->action
$this->request->param('paramname')
$this->request->param('paramname')
Unlike K2 arguments in K3 are accessed via kays which you define in your routes.
与 K3 中的 K2 参数不同，通过您在路由中定义的 kay 访问。
Take for example this url:
以这个网址为例：
Route::set('default', '(<controller>(/<action>(/<id>)))')
->defaults(array('controller' => 'welcome', 'action' => 'index'));
To access the "id" argument you'd call
要访问您要调用的“id”参数
$this->request->param('id')
$this->request->param('id')
You can't access the controller / action arguments from the param() method.
您无法从 param() 方法访问控制器/动作参数。
Note, you can also use Request::instance()to get the global (or "master") request instance.
请注意，您还可以使用Request::instance()获取全局（或“主”）请求实例。

Updated answer for Kohana 3.2, from the user guide:
来自用户指南的Kohana 3.2更新答案：
// From within a controller:
$this->request->action();
$this->request->controller();
$this->request->directory();
// Can be used anywhere:
Request::current()->action();
Request::current()->controller();
Request::current()->directory();

For those using Kohana >= 3.1, it might be useful to notice that some properties of the Request object have been converted to methods.
对于那些使用 Kohana >= 3.1 的人来说，注意到 Request 对象的某些属性已转换为方法可能会很有用。
E.g. Request::controlleris now Request::controller()(or $this->request->controller()when you're inside a controller).
例如Request::controller现在Request::controller()（或$this->request->controller()当您在控制器内时）。
For more information, I'd like to reference to the Kohana upgrade guide on http://kohanaframework.org/3.1/guide/kohana/upgrading
有关更多信息，我想参考http://kohanaframework.org/3.1/guide/kohana/upgrading上的 Kohana 升级指南
