Ajax和状态302 [英] Ajax and status 302

问题描述

我在使用AJAX的问题（和/或jQuery的AJAX）和状态302。

I'm having a problem with ajax (and/or jQuery ajax) and status 302.

这就是我想：

var xhr = new XMLHttpRequest();
xhr.open("GET", 'some_page_that_I_cant_change.php');
xhr.onreadystatechange = function(){
    console.log(xhr.readyState, xhr.status);
};
xhr.send(null);

在 some_page_that_I_cant_change.php 重定向到一个的.bin 与 302 code。我不想下载此文件，我只是想知道这个文件的路径。例如：

The some_page_that_I_cant_change.php redirects to a .bin with 302 code. I do not want to download this file, I just want know the path to the file. Example:

./some_page_that_I_cant_change.php
./path/to/bin/file.bin << I wan't only this path as string

问题是，Chrome会自动重定向到文件，瞒着我的路径，脚本。是否有解决方法吗？

The problem is that Chrome automatically redirects to the file, without telling me the path to script. Is there a workaround for this?

推荐答案

如果您使用的是HEAD请求，而不是GET请求，我怀疑会做你想做的。您应该只看到响应，没有响应主体（即没有.bin文件会下载）头。

If you use a HEAD request instead of a GET request, I suspect that will do what you want. You should only see headers in the response, no response body (i.e., no .bin will download).
