php - 跨域 AJAX 不工作 PHP

Question

我试图根据这个答案实现跨域 AJAX 请求。

http://jsfiddle.net/PXSMQ/1/

我添加了以下标题：

header('Access-Control-Allow-Origin:  *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
header('Access-Control-Max-Age: 1000');
header('Access-Control-Allow-Headers: Content-Type');
header("Access-Control-Allow-Headers: x-requested-with");
header('Access-Control-Allow-Headers: x-csrf-token');

但我仍然收到此错误：

XMLHttpRequest cannot load http://www.belardi.ro/userTrack/addData.php. Origin http://fiddle.jshell.net is not allowed by Access-Control-Allow-Origin. 

Answer 1

Access Control必须在您将请求发送到的服务器上配置标头。你不能自己设置它们。如果您向其发送请求的服务器未正确配置，您将无法发出这些请求。

Answer 2

这些标头未出现在以下响应中addData.php：
