angularjs – Internet Explorer 11替换授权头

什么会导致Internet Explorer替换HTTP标头

授权：承载<服务器提供令牌>

同

授权：协商<某个令牌>

在提出AJAX请求时？

细节

在Internet Explorer中，配置为包含头部授权：承载的一些AJAX请求正由Internet Explorer发送，标题为Authorization：Negotiate …。

例如，Fiddler显示三个请求中的前两个包含Authorization：Bearer …头，而第三个请求突然包含Authorization：Negotiate …头。前两个请求成功，第三个请求失败，因为请求无法正确认证。

所有请求都使用相同的客户端代码构建，并且一个接一个地(在一秒钟内)。我已经验证了授权头在所有三种情况下都正确地包含承载令牌，直到请求被提供给浏览器为止。

此外，我在Chrome中看不到同样的行为;它只发生在IE中。

这些请求是通过AngularJS $ http服务进行的，后端是在IIS中托管的ASP.NET Web API。

我们遇到Internet Explorer正在缓存凭据的问题。我们可以使用以下脚本解决问题：

document.execCommand('ClearAuthenticationCache','false');
