HTTP OPTIONS error in Phil Sturgeon's Codeigniter Restserver and Backbone.js

Question

My backbone.js application throwing an HTTP OPTIONS not found error when I try to save a model to my restful web service that\'s located on another host/URL.

Answer 1

You can also modify the $allowed_http_methods property in your subclass to exclude the options method. Previous versions of REST_controller did nothing with OPTIONS and adding this line seems to mimic that behavior:

protected $allowed_http_methods = array('get', 'delete', 'post', 'put');

Answer 2

I encountered exactly the same problem. To solve it I have a MY_REST_Controller.php in core and all my REST API controllers use it as a base class. I simply added a constructor like this to handle OPTIONS requests.

function __construct() {

    header('Access-Control-Allow-Origin: *');
    header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method");
    header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
    $method = $_SERVER['REQUEST_METHOD'];
    if($method == "OPTIONS") {
        die();
    }
    parent::__construct();
}

This just checks if the request type is OPTIONS and if so just dies out which return a code 200 for the request.
