await $.ajax({

        url: "v1/record",

        type: "POST",

        headers: { "content-type": "appication/json", "SLIEND": "XGH" },

        data: JSON.stringify({

                "username": "xxx",

                "password": "ecd"

        }),

        success: function (response.headers) {

            console.log(response.headers);

        }

});

如何从发送一个ajax http请求中获取返回的响应头？response.headers
