Response header is present in browser but not parsed by Angular $http response.headers()

Question

In our Angular app, we need to parse response headers of some $http.

In particular we need to parse some X-prefixed response headers, for example X-Total-Results:

Answer 1

Use $httpProvider.interceptors you can intercept both the request as well as the response

for example

$httpProvider.interceptors.push(['$q', '$injector', function ($q, $injector) {
             return {
                 'responseError': function (response) {
                     console.log(response.config);
                 },
                 'response': function (response) {
                     console.log(response.config);
                 },
                 'request': function (response) {
                     console.log(response.config);
                 },
             };
         }]);

Update : You can retrive your headers info in call itself

$http.({method: 'GET', url: apiUrl)
    .then( (data, status, headers, config){
        console.log('headers: ', config.headers);
        console.log('results header: ', config.headers('X-Total-Results'));
        // ...
    })
