Re: Jquery mobile+Phonegap mobile app and authentication

Arash,

I seem to have the same problem, would you mind posting your solution with your sample code and all?

Thanks Tarique, it looks to be the correct way but i didn't have any success using it!

Here is what i did:

1. used HTTP Basic Authentication

class AppController extends Controller {
    public $components = array(
        'Session',
        'RequestHandler',
        'Auth' => array(
            'authenticate' => array(
                'Basic' => array(
                    'fields' => array('username' => 'email'),
                    'realm' => 'touch'
                ),
            ),
        )
    );
}

2. created a login method which lets cross domain requests and cros domain authorization

class UsersController extends AppController {
    public function login() {
        header("Access-Control-Allow-Origin: *");
        header("Access-Control-Allow-Headers: Authorization");
        $response = false;
        if ($this->Auth->login()) {
            $response = true;
        }
        $this->set('response',$response);
    }

3. i've added this line to router file so that i can use json

Router::parseExtensions('json');

4. in the client side, i make login request using ajax like this:

$.ajax({
            url: url,
            dataType: "json",
            crossDomain: true,
            beforeSend: function(xhr){
                xhr.setRequestHeader("Authorization", "Basic " + Base64.encode(email + ":" + password));
            },
            success: function ( response ) {
                console.log(response);
            },           
            error: function (xhr, ajaxOptions, thrownError) {
                console.log(xhr);
            }
        });

The problem is that after i login successfully the next ajax requests get 401 (Unauthorized), i've tried to debug the problem and it seems that once client login, the next ajax requests get 401 because the get user method in BasicAuthenticate class can't get the user via env('PHP_AUTH_USER') and env('PHP_AUTH_PW')

Any idea why after successful ajax login the next ajax requests get 401 (Unauthorized) response?! why the authentication system can't get user by
env('PHP_AUTH_USER') ?
