How to access HTTP headers of request in AngularJS

Question

I know I can access an HTTP request's GET parameters in AngularJS with

$location.search().parameterOfInterest

But how do I access HTTP headers of the request?

I'm not using $http here. I'm asking about request to an AngularJS web page.

This question and answers makes me believe this is could be not possible: Accessing the web page's HTTP Headers in JavaScript

Answer 1

You can use a request interceptor that is called with an HTTP configuration object. An HTTP configuration object has a header property that you can freely access / modify inside your interceptor.

The response object of promise also has a header property that you can access.
