AJAX请求得到时会发生什么＆QUOT; 302＆搬迁QUOT;响应？ [英] What happens when an AJAX request gets a "302 Moved" response?

问题描述

我想不修改后端AJAXify旧网站的形式。本来，后端将响应以感动302接收后的形式重定向到一个谢谢你页面。

I'm trying to AJAXify an old website form without modifying the back end. Originally, the backend would response with a "302 Moved" redirect to a "thank you" page after receiving the form.

现在，当我尝试使用jQuery的$就调用提交表单，表单数据被成功提交，但感动302重定向似乎得到由浏览器取消和jQuery不知道是怎么回事

Now, when I try to submit the form using a jQuery $.ajax call, the form data gets submitted successfully, but the "302 Moved" redirect seems to get cancelled by the browser and jQuery doesn't know what's going on.

我的问题是，无论发生什么情况，$就调用返回的错误和状态= 0，所以我没有办法成功的区分提交和错误。

My problem is that no matter what happens, the $.ajax call returns with an error and status = 0, so I have no way to distinguish between a successful submit and an error.

有没有一种方法，以prevent从试图跟随重定向，或至少找回了正确的响应codeS的浏览器？ （我使用的浏览器。）

Is there a way to prevent the browser from trying to follow the redirect, or at least getting back the proper response codes? (I'm using Chrome.)

推荐答案

我觉得没什么，你不能做到这一点不改变背end.You已经改变响应头，为Ajax知道/了解什么do.If你犯了一个重定向，你必须改变标题，因为Ajax调用的响应不会去做。

I think no,you can't do it without changing the back-end.You have to change the response header,for Ajax to know/understand what to do.If you made a redirect,you have to change the header,because Ajax call response will not do it.
