如何使用$ this-> request-> param of Kohana来获取请求变量

Question

我在kohana写了一个样本控制器

    <?php

defined('SYSPATH') OR die('No direct access allowed.');

class Controller_Album extends Controller {

  public function action_index() {
    $content=$this->request->param('id','value is null');   
    $this->response->body($content);
  }

}

但是当我试图点击url http:// localhost/k/album？id = 4时 我得到NULL值.如何使用request-> param访问kohana中的请求变量,而不使用$ _GET和$ _POST方法？

Answer 1

在Kohana的V3.1 +请求类有query()和post()方法.他们兼作getter和setter:

// get $_POST data
$data = $this->request->post();
// returns $_GET['foo'] or NULL if not exists
$foo = $this->request->query('foo'); 

// set $_POST['foo'] value for the executing request
$request->post('foo', 'bar');
// or put array of vars. All existing data will be deleted!
$request->query(array('foo' => 'bar'));

但请记住,设置GET/POST数据不会使当前$ _GET/$ _ POST值超载.它们将在请求执行($request->execute()调用)后发送.
