Request from across origins in AmpersandJS is being made

Here is a sample AmpersandJS model:

var AmpersandModel = require('ampersand-model');

module.exports = AmpersandModel.extend({
    urlRoot: 'http://0.0.0.0:4567/api/v1/people',
    props: {
        id: 'any',
        name: ['string', true, ''],
        wins: ['number', true, 0],
        draws: ['number', true, 0],
        looses: ['number', true, 0]
    },

    ajaxConfig: function () {
        return {
            headers: {
                'Access-Control-Allow-Origin': '*',
                'Access-Control-Allow-Methods': "GET, POST, PUT, DELETE, OPTIONS",
                'Access-Control-Allow-Headers': "accept, authorization, origin"
            },
            xhrFields: {
                'withCredentials': false
            }
        };
    }
});

After calling 'save' on the model, the request method changes to OPTIONS and an error is displayed:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://0.0.0.0:4567/api/v1/people. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

Do you have any suggestions on how to overcome this issue?

Answer №1

It seems like the issue may be with the server not sending the correct headers. The model should not have to specify any CORS-related headers because the browser typically already includes the necessary request headers.

For more information on CORS headers, you can visit this page on CORS Headers overview. The headers you have set in your ajaxConfig are the ones that the server needs to include in the response to permit your cross-origin request.
