"Exploring the world of AngularJS with Basic Authentication over HTTP

I am currently facing an issue with my Angular app that is unable to access a test database. Strangely, this problem started over the weekend without any changes made to the Angular code. Here's what I'm experiencing.

In order to access the test database, I need to provide a username and password due to Basic HTTP Auth. This results in my resource URL looking like this.

angular.module("CoolApp.misc")

.factory('Ad', ad)

ad.$inject = ['$resource'];

function ad($resource) {
  return $resource('http://username:<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0a7a6b79797d65786e4a687f636e6564616674686461">[email protected]</a>/api/advertisement.json');
}

When I try to run

Ad.get({}, function(resp) {}, function(badresp) {console.log(badresp)})

I receive the badresp object in the console. Upon checking the config headers section, I notice the URL looks like...

url: "http://<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ea9f998f98848b878faa889f838085808fa884868580"><span class="__cf_email__" data-cf-email="18796779676c70696a61687a307d7173">[email protected]</span></a>/api/advertisement.json"

Why is the header not passing the password if I included it in the URL? Could this be why I am seeing a

No 'Access-Control-Allow-Origin' header is present on the requested resource.
error in my console?

Just for reference, here is my http configuration

angular.module("CoolApp")

.config(config);

config.$inject = ["$httpProvider"];

function config($httpProvider) {
  $httpProvider.defaults.useXDomain = true;
  //$httpProvider.defaults.withCredentials = true;
  delete $httpProvider.defaults.headers.common["X-Requested-With"];
  $httpProvider.defaults.headers.common["Accept"] = "application/json";
  $httpProvider.defaults.headers.common["Content-Type"] = "application/json";
}

In conclusion, I would like to know what could be causing this issue and how I can resolve it.

Answer №1

The absence of the 'Access-Control-Allow-Origin' header has been detected on the requested resource.
If you can confirm that there have been no modifications to the front-end code, then it is likely that a change was made on the server side... Judging by the error message provided, it appears that either the Access-Control-Allow-Origin header was removed or the origins were restricted.

This issue cannot be resolved on the client side; the necessary adjustments must be made on the server.
