call codeigniter API from outside the framework -

i have iphone application perform calls api developed codeigniter. since new framework, want know such api located ? url requested iphone application api following:

http://example.com/site/welcome/admin/api/processingdocuments/

i got on application/libraries folder , there bench of php files rest.php , rest_controller.php. these files looking for? since url above doesn't point specific file, how know api being called? thank in advance.

when using phil sturgeon's codeigniter restserver (which seems using), set controller within application/controllers directory , extend class.

let's call controller foobar, , looks this:

class foobar extends rest_controller {    //... methods here  } 

in case, access endpoint @ http://example.com/foobar

---

the url references controllers, , not rest_controller directly.

urls this:

http://example.com/{controller}/{method}/{param1}/{param2}/.../{paramn} 

if method not specified, defaults index()

---

further, restserver allows map methods http request methods. such that

get example.com/foobar map method index_get() post example.com/foobar map method index_post() ..and on.

i highly recommend read documentation

---

in example, expect controller being called located @ application/controllers/site.

however, might have been modified using htaccess rewrite rules (check .htaccess file), or via redefined ci routes (check application/config/routes.php).

---

if else fails:

under default configurations, should find them, however, ci malleable routes , hard might be. best bet grep directory words extends rest_controller since wherever controllers are, extending class.
