Handle error codes (401, 403) with Restangular

Question

I am building an app using Restangular. I would implement in one place handling of errors like 401, 403, 500 etc in a response interceptor.

This is what I wrote:

RestangularProvider.setResponseExtractor(function(response, operation, what, url) {
  switch(response.meta.code) {
    case 200:
      // Handle 200
    break;

    case 401:
      // Redirect to login
    break;

    /* ... */

    default:
    break;
  }
}

What actually happens it's that the 200 is correctly seen but this method is not hit at all for the 401. The JSON I get from server side it is formatted like this for successful responses:

{"meta":{"apiVersion":"0.1","code":200,"errors":null},"response":{"response":"value"}}

and

{"meta":{"apiVersion":"0.1","code":401,"errors":[{"code":401,"message":"Unauthorized"}]},"response":null}

for errors. The response header contains the Status Code:401 Unauthorized as well. What am I doing wrong?

Answer 1

401 and any error code will hit the errorInterceptor, not the responseInterceptor. responseInterceptor is only called with successful responses!
