那些遇到过的问题

具有302重定向和withCredentials = true的Chrome和CORS

Ken*_* D. 5 google-chrome xmlhttprequest cors http-status-code-302

使用基于Chromium的浏览器和包含302重定向的CORS请求时遇到问题。更具体地说，我在Chromium版本34-42（含）之间遇到麻烦；43和更高版本有效，并且似乎33和更早版本也适用（我在33到28之前还没有测试太多）。

我的XHR请求使用withCredentials = true，因此不允许Access-Control-Allow-Origin =“ *”；服务器必须使用Access-Control-Allow-Origin标头进行回复，该标头与传入请求的Origin标头相呼应。

在收到第一个302之后，Chromium 43和更高版本发送“ Origin：null”作为重定向请求的一部分，并接受“ Access-Control-Allow-Origin：null”作为响应（Firefox也是如此）。

Chromium系列34-42都将所有请求的主机名发送为Origin，此后的几个问题表明，仅 在Access-Control-Allow-Origin设置为“ *” 时才支持CORS重定向，并且“原始” XHR不得将allow-credentials设置为true”，例如：

我希望这是一个误解，作为应用程序开发人员，我可以在客户端和/或服务器上执行某些操作，以强制那些版本不取消重定向，否则，将无法解决此问题。

版本33及更早版本为每个请求发送了完整的主机名，并且完整的往返操作有效。

对于一种可能解决办法我已经从事实，我其实也源于实验并不需要withCredentials =真正的跨域请求，我只需要它重定向回原始主机交换基于cookie的身份验证一个access_token，但是除非遵循原始302跨域请求发送，否则我无法找到一种方法来使客户端在向其自身发送302时发送cookie。

为了说明这一点，以下是chrome：// net-internals /＃events日志中摘录的有关使用Chrome 43的成功请求的摘录：
