问题描述
我正在构建一个有声书应用程序，并且已将音频文件上传到Firebase Storage。我的问题是，在旧金山和多伦多，我经历了不同的表演。我的印象是Firebase Storage内置了CDN。如果是这样，我需要在某个地方启用它吗？如果没有，如何将GCP CDN添加到Firebase身份验证后面的Firebase存储文件中？
检查域 storage.googleapis.com （托管我的Firebase存储文件的位置）显示它正在使用Google CDN。
以下是我的一个公共音频文件请求的响应标头：
接受范围：字节
alt-svc：quic =：443; ma = 2592000; v = 46,44,43,39
缓存控制：公共，最大年龄= 3600
content-disposition：内联； filename * = utf-8''G4PT7dPIyEuIz74BtTmm_FallIsTheLastSeasonOfTheYear.mp3
content-length：3162637

我联系了Firebase支持，这是我得到的答案：
I'm building an audiobook app and have uploaded the audio files on Firebase Storage. My problem is that I experience different performances in San Francisco vs Toronto. I am under the impression that Firebase Storage has built-in CDN. if so, Do I need to enable it somewhere? if not, how do I add GCP CDN to my Firebase Storage files behind Firebase Auth??
Checking the domain storage.googleapis.com which is where my Firebase Storage files are hosted shows that it is using the Google CDN.
Here are the response headers for one of my public audio file request:
accept-ranges: bytes
alt-svc: quic=":443"; ma=2592000; v="46,44,43,39"
cache-control: public, max-age=3600
content-disposition: inline; filename*=utf-8''G4PT7dPIyEuIz74BtTmm_FallIsTheLastSeasonOfTheYear.mp3
content-length: 3162637
content-type: audio/mp3
