XHR 重定向问题

发布于 2024-12-03 03:05:21 字数 749 浏览 0 评论 0原文

假设我有三个域 A、B 和 C。B 和 CI 都确保在发出请求时发送 Access-Control-Allow-Origin: *。

现在在域 AI 上运行这样的 XHR：

xhr.open("GET", "B/abc.wav")
xhr.send()

B 将重定向到 C。

Content-Type: text/plain
Connection: keep-alive
Keep-Alive: timeout=60
Location: http://C/something/abc.wav
Content-Length: 0
Access-Control-Allow-Origin: *

C 将回复

Content-Type: audio/wav
Connection: keep-alive
Keep-Alive: timeout=65
Accept-Ranges: bytes
Content-Length: 1003914
Access-Control-Allow-Origin: *

我遇到的问题是，在 Chrome 14.0.835.126 beta-m 中，我收到一个错误，但没有给我任何提示。这失败了。

我只看到“[Exception: DOMException]”作为 XHR 的响应。网络上的大多数示例都建议添加我已经完成的 ACAO 标头，但实际上没有一个示例讨论多重重定向的场景。这有可能吗？

Imagine I have three domains A, B, and C. On both B and C I have made sure that Access-Control-Allow-Origin: * is sent when making a request.

Now on domain A I run an XHR like this:

xhr.open("GET", "B/abc.wav")
xhr.send()

B will make a redirect to C.

Content-Type: text/plain
Connection: keep-alive
Keep-Alive: timeout=60
Location: http://C/something/abc.wav
Content-Length: 0
Access-Control-Allow-Origin: *

C will reply with

Content-Type: audio/wav
Connection: keep-alive
Keep-Alive: timeout=65
Accept-Ranges: bytes
Content-Length: 1003914
Access-Control-Allow-Origin: *

The issue I have is that in Chrome 14.0.835.126 beta-m I get an error as a result without giving me any hint of why this fails.

I only see "[Exception: DOMException]" as the response of the XHR.
Most examples on the web suggest to add the ACAO header which I have done but none actually talks about the scenario of multiple redirects. Is this possible at all?
