如何从 AJAX 响应中获取 cookie? [英] How to get a cookie from an AJAX response?

问题描述

我在同一个域上有一个 $.ajax 请求，我想读取 cookie.它不断返回 null.

I have a $.ajax request on the same domain and I want to read the cookie. It keeps returning null.

$.ajax({
    type: 'GET',
    url: myUrl,
    success: function(output, status, xhr) {
        alert(xhr.getResponseHeader("MyCookie"));
    },
    cache: false
});

有什么想法吗?为此，我正在使用 Chrome.

Any ideas? I'm using Chrome for this.

推荐答案

您正在寻找 Set-Cookie 的响应头:

You're looking for a response header of Set-Cookie:

xhr.getResponseHeader('Set-Cookie');

不过它不适用于 HTTPOnly cookie.

It won't work with HTTPOnly cookies though.

根据XMLHttpRequest Level 1 和 XMLHttpRequest Level 2，这特定的响应头属于禁止的"范围.您可以使用 getResponseHeader() 获取响应标头，因此它可以工作的唯一原因基本上是顽皮"；浏览器.

According to the XMLHttpRequest Level 1 and XMLHttpRequest Level 2, this particular response headers falls under the "forbidden" response headers that you can obtain using getResponseHeader(), so the only reason why this could work is basically a "naughty" browser.
