I had to setup JWT auth in angular recently as well, here's my authentication service that posts to the server side api and uses local storage to hold on to the token.
For more info I wrote this post that includes a working demo with a fake backend.
(function () {
'use strict';
angular
.module('app')
.factory('AuthenticationService', Service);
function Service($http, $localStorage) {
var service = {};
service.Login = Login;
service.Logout = Logout;
return service;
function Login(username, password, callback) {
$http.post('/api/authenticate', { username: username, password: password })
.success(function (response) {
// login successful if there's a token in the response
if (response.token) {
// store username and token in local storage to keep user logged in between page refreshes
$localStorage.currentUser = { username: username, token: response.token };
// add jwt token to auth header for all requests made by the $http service
$http.defaults.headers.common.Authorization = 'Bearer ' + response.token;
// execute callback with true to indicate successful login
callback(true);
} else {
// execute callback with false to indicate failed login
callback(false);
}
});
}
function Logout() {
// remove user from local storage and clear http auth header
delete $localStorage.currentUser;
$http.defaults.headers.common.Authorization = '';
}
}
})();
