No 'Access-Control-Allow-Origin' error in HMVC Codeigniter

Question

When Page loads in my console it shows this error

Font from origin ' http://example.com ' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://www.example.com ' is therefore not allowed access.

and when i call ajax function. it show this error

XMLHttpRequest cannot load http://example.com/index.php/home/getCity?city=d . No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://www.example.com ' is therefore not allowed access.

Which ajax functions are in home controller. But i'm in another controller. may be I think it was problem. how can i solve this ?

Answer 1

对于Codeignitor中的跨域资源，必须在<?php标签开始后立即在控制器中包括此行

header('Access-Control-Allow-Origin: *');

Answer 2

<?php
header('Access-Control-Allow-Origin: *');
class Myclass extends CI_Controller {

}

This works perfectly fine in codeigniter
