- CDN.js serves

application/octet-streamis fine.
application/octet-stream很好。
On the Google CDN we do it as application/jsononly so you can view source in the browser.
在 Google CDN 上，我们这样做application/json只是为了您可以在浏览器中查看源代码。
No DevTools actually care what the content-type is, so you can ignore it safely.
没有 DevTools 实际上关心内容类型是什么，所以你可以安全地忽略它。
