当您将应用服务器从 GCM 迁移到 FCM 时，旧客户端会发生什么情况?

What happens to older clients when you migrate an app server from GCM to FCM?(当您将应用服务器从 GCM 迁移到 FCM 时，旧客户端会发生什么情况?)

问题描述

我正在考虑迁移到 FCM.事情的客户端相当简单，你移动一些代码并完成它.但是，在应用服务器上，出于显而易见的原因，我还需要支持旧客户端.我需要知道将 GCM 项目迁移到 FCM 时会发生什么.FCM 是否也会自动将消息转发到基于 GCM 的旧客户端?或者我是否需要将每条消息发送两次，一次发送到 FCM，一次发送到 GCM?这将如何影响特定于实现的内容，例如从 Firebase 的 Web 控制台发送的消息?有什么我应该注意的细节吗?

I'm considering migration to FCM. The client side of things is rather simple, you move some code around and get it done. However, on the app server, I'd need to support older clients as well, for obvious reasons. I need to know what happens when I migrate a GCM project to FCM. Does FCM automatically forward messages to older GCM-based clients as well? Or would I need to send each message twice, once to FCM and once to GCM? How will this impact implementation-specific stuff such as messages sent from Firebase's web console? Are there any details I should be aware of?

推荐答案

使用 FCM(导入的项目或使用它的端点，无论您是什么意思)仍然与 GCM 客户端(特别是令牌)兼容.他们仍然可以像往常一样接收消息.

Using FCM (an imported project or using it's endpoint, whichever you mean) is still compatible with GCM clients (specifically tokens). They'd still be able to receive messages like usual.
