在ajax请求中检测重定向? [英] Detecting a redirect in ajax request?

问题描述

我想使用 jQuery 获取 URL 并明确检查它是否以 302 重定向响应，但不遵循重定向.

I want to use jQuery to GET a URL and explicitly check if it responded with a 302 redirect, but not follow the redirect.

jQuery 的 $.ajax 似乎总是跟随重定向.如何防止这种情况发生，并在不遵循重定向的情况下查看重定向?

jQuery's $.ajax appears to always follow redirects. How can I prevent this, and see the redirect without following it?

有各种标题为jquery ajax redirect"的问题，但它们似乎都涉及完成其他一些目标，而不仅仅是直接检查服务器提供的状态.

There are various questions with titles like "jquery ajax redirect" but they all appear to involve accomplishing some other goal, rather than just directly checking the status that a server gives.
