Question

我在包含私有文件的S3存储空间上使用CloudFront Web分发流式传输文件（CloudFront可以访问它）。我使用AWS WAF验证请求是否来自我的域（带有referer标头），以避免使用其URL的简单复制粘贴直接下载音频文件。要播放音频文件，我使用SoundManager2。

问题：它就像桌面浏览器（Chrome，Firefox和Safari）上的魅力一样，但流媒体从未开始在移动设备上播放（在iOs和Android上测试过）。我不明白为什么。

在网络版上，SoundManager2发送第一个请求并取消它：

Request URL:https://XXXXXXXX.cloudfront.net/uploads/track/s3_file/XXX/XXXXXXXXXXXXX.mp3

**Request Headers**

在移动设备上，SoundManager2在日志中达到playing状态，但现在播放音乐。有人知道为什么流不能在移动设备上启动???

Answer 1

在Windows Mobile上，这可以工作在此处查看有关某些移动浏览器上有关WAF和HTML5音频/视频的说明：
Preventing Amazon Cloudfront hotlinking

移动流媒体无法使用WAF + CloudFront + S3（在桌面浏览器上工作！）
