CORS problem in app with Access-Control-Allow-Origin

Hello, everybody,

I have created a rest api on my server to do some tests following Matt’s tutorial on youtube:
Ionic Creator Tutorials // Using APIs with Angular $http // Part 1 (

I just want to try sending a couple of data from a form and receive a response.
When I send the data to my server I get this error in the network console:
Failed to load Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘’ is therefore not allowed access.

I tried to give access to using .htaccess but it doesn’t work.

Using an chrome extension to send data via json (postman) works perfectly.

Using this app, the data is send like this:
POST /clients/web/usersonapis HTTP/1.1
Host: mydomain. com
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 03764585-20c4-70bc-f92a-c580ba7fcbce

Can someone give me a hint as to what configuration I should apply on my server to avoid this error?

$token = null;
$headers = apache_request_headers();
if (!$headers) {
    $headers = http_get_request_headers();

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET,POST');
header( 'Access-Control-Allow-Headers: Authorization, Content-Type' );

$username = 'dumb';
$password = 't3stp4ssY=';

    $passfail = 'Fail';
} else {
    if ($_SERVER['PHP_AUTH_PW'] == $password && $_SERVER['PHP_AUTH_USER'] == $username) {
        $passfail = 'Pass';
    } else {
        $passfail = 'Fail';

$ret = [
    'result' => 'OK',
    'Auth' => $passfail
print json_encode($ret);

Thank you. As soon as I can, I’ll try your solution.:wink:
