Following Restangular's documentation and includes an example of this:
// GET to http://www.google.com/ You set the URL in this case
Restangular.allUrl('googlers', 'http://www.google.com/').getList();
I am trying to do the same for angel.co
$scope.trial = Restangular.allUrl('googlers', 'https://api.angel.co/1/users/267770').getList();
And keep getting error
XMLHttpRequest cannot load https://api.angel.co/1/users/267770. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access.
Any solutions?
The server (api.angel.co) is not responding with Access-Control headers which results in this error.
When sending XHR requests to domains different from the origin domain web browsers are checking if the service allows this. In your case api.angel.co would need to include the header Access-Control-Allow-Origin: * as part of the response (which it does not).
Assuming you cannot change api.angel.co, an alternative would be to build a server-side proxy (e.g. in node.js) which allows Cross-Origin Resource Sharing.
Check out this great article about Cross-Origin Resource Sharing (CORS).
