我无法使用ajax调用发送自定义标头

Question

我正在尝试使用ajax调用添加自定义标头，但我不能这样做。

这是ajax调用

 $j(document).ready(function(){
    $j.ajax({
  method: 'POST',
  url: 'https://mysecoure.com/test/v1/api/getWebSessionKey',
  headers: {'Content-Type': 'application/json','Authorization' : 'Bearer 69bb9df-b7e5-b6583392fce8','SecureHash':'d1eb5d981cc036764979fc26c837ecc255cfbad208b583a'},
  data:  {
      'MERCH_ORDER_ID' : 'ORDER12234213',
      'TXN_AMOUNT' : '12.00',
      'RET_URL_SUCC' : 'http://localhost:8580/mysecure/return.jsp',
      'SELLER_NAME' : 'test'
    }
})
  .done(function( msg ) {
    console.log(msg);
  });
  });

但我在控制台上收到此错误。

 XMLHttpRequest cannot load https://mysecoure.com/test/v1/api/getWebSessionKey. Request header field SecureHash is not allowed by Access-Control-Allow-Headers in preflight response.

它传递Access-Control-Request-Headers:authorization,content-type,securehash
