AngularJS does not support the 'Access-Control-Allow-Origin' header

I'm struggling to find a solution for the cross-domain issue in my code:

$apiUrl = 'https://gtmetrix.com/api/0.1/test';
$apiUser = '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c2a8ada755e4b3afb5bcb9acabb3b6edb0bcd7adaf">[email protected]</a>';
$apiKey = '1234567890';
$requestUrl = 'http://converge.io';

    function FetchCtrl($scope, $http, $templateCache) {

        $scope.method = 'post';
        $scope.url = $requestUrl;

        $scope.fetch = function() {
            $scope.code = null;
            $scope.response = null;

            $http({method: $scope.method, url: $apiUrl + '?login-user=' + $apiUser + '&login-pass=34bcb5c46bc6d5fb18a8552820027eb9' + '&url=' + $scope.url, cache: $templateCache}).
            success(function(data, status) {
                $scope.status = status;
                $scope.data = data;
            }).
            error(function(data, status) {
                $scope.data = data || "Request failed";
                $scope.status = status;
            });
        };
        $scope.fetch();

        $scope.updateModel = function(method, url) {
            $scope.method = method;
            $scope.url = url;
        };

    }

The error message I am receiving is:

XMLHttpRequest cannot load https://gtmetrix.com/api/0.1/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b2c6d7c1c68ddeddd5dbdc9fc7c1d7c08fd8ddd7f2c4d3dcd6dbd5c0ddc7c29cd1dddf">[email protected]</a>&login-pass=1234567890&url=http://converge.io. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://converge' is therefore not allowed access. 

It seems like I need to include the following line, but I can't seem to make it work:

delete $http.defaults.headers.common['X-Requested-With'];

Answer №1

There could be a potential solution to this issue. Allow me to share the steps:

  1. Create a simple PHP script on your server (or utilize any server-side scripting language)
  2. Invoke it using ajax along with the necessary API parameters (such as URL, user, key, etc.)
  3. Implement CURL to execute the request (or use an equivalent method)
  4. Output the desired results

Instead of directly calling gtmetrix through xhttprequest, consider calling the custom script you have developed.
