Question

I need a way to decrypt encrypted URL request parameters into the original Yii controller/action path. Example:

From: http://www.site.com/feh923rfj932 (encrypted)
To: http://www.site.com/api/view/1 (decrypted)

Is there some CUrlManager router callback I can use to implement a decrypt method?

Answer 1

Yes, Yii provides an easy way to implement your own URL logic using Custom Url Classes “callbacks”.

Basically, you will declare a new rule that points to your new decoder/encoder class:

'rules' => array(
  '' => 'site/index', // normal URL rules
  array( // your custom URL handler
    'class' => 'application.components.CustomUrlRule',
  ),
),

Your URL class will look something like this:

class CustomUrlRule extends CBaseUrlRule {

  public function createUrl($manager,$route,$params,$ampersand) {
    return your_encrypt_method($route);
  }

  public function parseUrl($manager,$request,$pathInfo,$rawPathInfo) {
    return your_decrypt_method($pathInfo);
  }
}
