Rest API Web Service - iOS - web-services

Question

Its my first time to use web service in iOS.
REST was my first choice and I use code igniter to form it.
I have my Controller:
require APPPATH.'/libraries/REST_Controller.php';
class Sample extends REST_Controller
{
function example_get()
{
$this->load->helper('arh');
$this->load->model('users');
$users_array = array();
$users = $this->users->get_all_users();
foreach($users as $user){
$new_array = array(
'id'=>$user->id ,
'name'=>$user->name,
'age'=>$user->age,
);
array_push( $users_array, $new_array);
}
$data['users'] = $users_array;
if($data)
{
$this->response($data, 200);
}
}
function user_put()
{
$this->load->model('users');
$this->users->insertAUser();
$message = array('message' => 'ADDED!');
$this->response($message, 200);
}
}
, using my web browser, accessing the URL http://localhost:8888/restApi/index.php/sample/example/format/json really works fine and gives this output:
{"users":[{"id":"1","name":"Porcopio","age":"99"},{"id":"2","name":"Name1","age":"24"},{"id":"3","name":"Porcopio","age":"99"},{"id":"4","name":"Porcopio","age":"99"},{"id":"5","name":"Luna","age":"99"}]}
, this gives me a great output using RKRequest by RestKit in my app.
The problem goes with the put method. This URL :
http://localhost:8888/restApi/index.php/sample/user
always give me an error like this:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<xml>
<status/>
<error>Unknown method.</error>
This is my Users model
<?php
class Users extends CI_Model {
function __construct()
{
parent::__construct();
}
function get_all_users()
{
$this->load->database();
$query = $this->db->get('users');
return $query->result();
}
function insertAUser(){
$this->load->database();
$data = array('name'=> "Sample Name", 'age'=>"99");
$this->db->insert('users', $data);
}
}
?>
What is the work around for my _put method why am I not inserting anything?
Thanks all!

Answer 1

Unless you set the method to PUT or POST, your web server is not going to treat it as such. When you enter URLs in a browser bar, that is almost always a GET request. You might try to use curl like
curl -X POST -d #filename http://your.url.path/whatever
Another link would be: https://superuser.com/questions/149329/what-is-the-curl-command-line-syntax-to-do-a-post-request
So you should be able to do a PUT similarly (perhaps with no data). Not really sure if this should be iOS tagged though :)

I got this problem by using Firefox plug in rest Client.
I just have to indicate the headers and the body to make put and post work.
