当用户第一次运行应用程序并注册FCM服务器时，我应该将令牌保存到另一个数据库吗？
1。如何从外部服务器获取设备令牌？现在我正在使用Firebase管理程序SDK。
目前没有任何API可以检索应用程序的所有注册令牌从服务器端。开发人员有责任将注册令牌发送并存储到从客户端应用程序生成的应用服务器中。
2。只有当应用程序连接到FCM服务器时才会生成设备标记 /firebase.google.com/docs/cloud-messaging/android/client#sample-registerrel =nofollow noreferrer> documentation 几乎涵盖了这一点（另见我的回答 $ b
在您的应用程序初次启动时，FCM SDK为客户端应用程序实例生成一个注册令牌。
它在技术上并没有连接到FCM服务器。它连接到FirebaseInstanceID服务（通过SDK），然后生成注册令牌。
3。我应该在用户第一次运行应用程序并注册FCM服务器时将令牌保存到另一个数据库吗？
1，你应该将它保存在可以轻松访问的地方发送消息。
How to get device tokens (FCM registration tokens) from Firebase?
I'm making mobile app using firebase and its server using node.js.
I want to send
push notificationmessage from server, but I don't know how to get devices token.
How to get device tokens from external server? I'm using Firebase admin SDK now.
Is the device token only generated when the app is connected fcm server?
Should I save token to another database when user first run the app and register FCM server?
解决方案1. How to get device tokens from external server? I'm using Firebase admin SDK now.
There is currently no API to retrieve all the Registration tokens for your app from the Server side. It's the developer's (you) responsibility to send and store the Registration token to your App Server, which is generated from the Client App side.
2. Is the device token only generated when the app is connected FCM server?
The documentation pretty much covered this (see also my answer here):
On initial startup of your app, the FCM SDK generates a registration token for the client app instance.
It doesn't technically get connected to the FCM Servers. It connects to the FirebaseInstanceID service (via the SDK), which in turn generates the Registration Token.
3. Should I save token to another database when user first run the app and register FCM server?
As I mentioned in #1, you should save it where you can easily access it to send a message.
