Google FCM 是否支持基于 HTTP 2 的 Apple APNs API？
Does Google FCM support's HTTP 2 based Apple APNs API?
根据苹果在 2021 年 4 月 1 日之前发出的新通知，所有应用程序都需要使用基于 HTTP/2 的 API，因为我们使用 FCM 进行云消息传递，需要确认 firebase 服务在未来可以正常工作，因为嗯，
The HTTP/2-based Apple Push Notification service (APNs) provider API
lets you take advantage of great features, such as authentication with
a JSON Web Token, improved error messaging, and per-notification
feedback. If you send push notifications with the legacy binary
protocol, we strongly recommend upgrading to the APNs provider API.
To give you additional time to prepare, the deadline to upgrade to the
APNs provider API has been extended to March 31, 2021. APNs will
no longer support the legacy binary protocol after this date.

刚收到来自 Firebase 支持的消息，我们这边不需要任何操作项。
The details about Updated APNs provider API deadline will not
have any performance impact or issues on FCM, and there’s no action
item needed on your end in relation to Apple Push Notification
service server certificate update.
Let me know if you have any clarifications.
