ionic2 - ionic problem No 'Access-Control-Allow-Origin'

Question

I'm working on an ionic apps. My problem is: when I try to get data from server I got this:

XMLHttpRequest cannot load https://mywebsite.com/api. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access.

I already try to add this to .htaccess:

<ifModule mod_headers.c>
Header set Access-Control-Allow-Origin: *
</ifModule>

And this to my api page (PHP): header('Access-Control-Allow-Origin: *');

but still not working

$http.get(url).success(function(response) {...}

Answer 1

Put it on top of your PHP file like:

<?php
header("Access-Control-Allow-Origin: *");
// then your stuff goes here

?>

Note: as with all uses of the PHP header function, this must be before any output has been sent from the server.
