Codeigniter路由 - 使用它太多了？

Question

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

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?

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

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

Let's take a look at both possibilities.

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

With routing, you can achieve it like this:

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

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
  }
}

}

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

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
  }

}

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