Ajax跨域请求COOKIE无法带上的解决办法

本文参考https://stackoverflow.com/questions/12840410/how-to-get-a-cookie-from-an-ajax-response

原生ajax请求方式:
var xhr = new XMLHttpRequest();  
xhr.open("POST", "http://xxxx.com/demo/b/index.php", true);  
xhr.withCredentials = true; //支持跨域发送cookies
xhr.send();
jquery的ajax的post方法请求:
$.ajax("https://example.com/v2/whatever", {
     method: 'GET',
     xhrFields: { withCredentials: true },
     crossDomain: true,
     success: function(response){},
     error: function(){}
  });
服务器端设置:

header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: http://www.xxx.com");
