Codeigniter路由-使用太多了吗？ [英] Codeigniter Routing - Using it too much?

问题描述

我是Codeigniter的新手，我正试图通过将旧站点转换为CI来习惯它。

I'm new to Codeigniter, and I'm trying to get accustomed to it by converting an old site into CI.

我无法理解的一件事是路由。如果我不想使用/ controller / method / id这样的url结构，则必须将其更改为 $ route ['controller /（：num）'] = controller / method / $ 1; 在route.php中。在我看来，这似乎效率低下，还有什么我应该做的吗？

One thing I'm having trouble understand is the routing. If I don't want to have my url structure like /controller/method/id, I have to change it to something like $route['controller/(:num)'] = "controller/method/$1"; in routes.php. It just seems inefficient to me, is there something else I should be doing?

例如，在我的网站上，URL是/ game / 4242和/ player / SomeDude

For example, on my site, the urls are /game/4242 and /player/SomeDude

推荐答案

好的，路由是有效的-替代方法是重新映射控制器。

Well, routing is effecient - the alternative is remapping your controllers.

让我们来看看这两种可能性。

Let's take a look at both possibilities.

一种虚构的情况：
稍后，您希望允许用户在其个人资料上显示徽章/勋章/成就/物品。

An imaginary situtation: At a later point, you'd like to allow your users to show badges/medals/achievements/something on their profile.

使用路由，您可以这样实现：

$route['player/(:any)/(:any)'] = "player/show_$2/$1";
$route['player/(:any)'] = "player/show_profile/$1";

然后您的控制器可能看起来像这样：

And your controller could in turn look like this:

class Player extends CI_Controller
{
  public function show_profile( $username )
  {
    // the profile info
  }

  public function show_badges( $username )
  {
    // the profiles badges
  }

  public function show_scores( $username )
  {
    // the profiles scores
  }
}

}

基本上，这使您可以在控制器中简单地添加另一个方法，并在该方法的前面加上 show _ （例如公共方法show_friends（$ username）），您可以通过访问 / player / SomeDude / friends

Basically, this allows you to simply add another method in your controller prefixing the method with show_ (like public method show_friends( $username ) )and you can access it instantly by going to /player/SomeDude/friends

看看替代方案，重新映射控制器将使您不使用路由，而是编写如下所示的控制器：

Looking at the alternative, remapping your controller would allow you not to use routes, but write a controller like this:

class Player extends CI_Controller
{

  public function _remap($username, $params = array())
  {
    if(empty($username))
      show_404();

    $this->user = $this->user_model->find($username);

    if(count($params) == 0)
      $method = 'index';
    else
      $method = $params[0];

    unset($params[0]); //No need to send the method along as a parameter

    $method = 'process_'.$method;
    if (method_exists($this, $method))
    {
      return call_user_func_array(array($this, $method), $params);
    }
    show_404();
  }

  public method process_index()
  {
    // the profile info
  }

  public method process_badges()
  {
    // the profiles badges
  }

  public method process_scores()
  {
    // the profiles scores
  }

}

我个人喜欢路由。我认为它是透明的，可以使我的控制器看起来更干净。

Personally, I like routing. I think it's transparent and makes my controllers look cleaner.
