How to retrieve the authorization token from the response header of an ajax call in angularjs?

问题

Basically the title has described everything. I send an api call, get a response, with Authorization in the header, and I want to retrieve this authorization token from the header because it is needed for subsuquent api calls. How should I get this info?

回答1:

You should take a look here: https://docs.angularjs.org/api/ng/service/$http

$http.get('yourUrl').
  success(function(data, status, headers, config) {
    console.log(headers);
  })

回答2:

$http passes headers to the success/error callbacks. The headers parameter is a function that takes a single argument that is an array. It returns all those header values as an array result.

$http.get('/someUrl')
     .success(function(data, status, headers) {
         console.log(headers(['Authorization']));
     });
