当谈到 Windows 手机（8.1，Lumia 925）上的 XHR 时，我有一种奇怪的行为。
我正在使用一个 javascript 库来执行一些 XHR 请求（Tin Can JS 库），它对设置一些标头的外部 URL 执行 PUT。如果我在 IE11 上运行与网页完全相同的代码，则请求会发送以下标头：
Accept: */*, referer: http://169.254.80.80:8080/dest/

如果我在由 Cordova 包装的 Windows Phone 上运行它，这些是标题：

明显缺少的是 Authorization 标头。我通过console.log进行了检查，即使在windows phone上也执行了适当的xhr.setRequestHeader，但似乎标头被丢弃或忽略了。
我找不到导致这种情况的原因或解决方法。
