从http标头响应获取日期

ajax

好的,因此我可以使用访问HTTP ajax响应标头

xhr.getAllResponseHeaders();

但似乎没有日期,尽管它在那里:

 [Chrome]
**Response Header**
Access-Control-Allow-Origin:*
Cache-Control:no-cache
Content-Length:8092
Content-Type:application/json; charset=utf-8
**Date:Thu, 15 Jan 2015 16:30:13 GMT**
Expires:-1
Pragma:no-cache
Server:Microsoft-IIS/8.0
TotalCount:116
X-AspNet-Version:4.0.30319
X-Powered-By:ASP.NET

而代码只显示了这一点:

[output on alert xhr.getAllResponseHeaders();]

Cache-Control: no-cache
Pragma: no-cache
Content-Type: application/json; charset=utf-8
Expires: -1

这是ajax调用:

   $.ajax({
        url: url,
        type: "GET",
        contentType: "application/json;charset=utf-8",
        async: true,
        success: function (data,status, xhr) {

        displayNewData(data);
        alert(xhr.getAllResponseHeaders());

    },
    error: function () {
    alert(url);

    }
});

有没有办法可以在响应头中获取日期?

这有帮助:

var req = new XMLHttpRequest();
req.open('GET', document.location, false);
req.send(null);
var headers = req.getAllResponseHeaders().toLowerCase();
alert(headers);
