如果有多个发件人ID，如何确定令牌是否需要刷新? [英] How to determine if token needs to be refreshed in case of multiple sender id?

问题描述

我的应用程序正在接收来自2 firebase项目的推送通知.我通过分别调用"getToken(String AuthorizedEntity，String scope)"来获取每个发件人ID的令牌.

My application is receiving the push notification from 2 firebase project. I am getting the tokens for each sender id by calling "getToken(String authorizedEntity, String scope)" separately.

String token1 = FirebaseInstanceId.getInstance().getToken("authorizedEntity1", "FCM");
String token2 = FirebaseInstanceId.getInstance().getToken("authorizedEntity2", "FCM");

根据 onTokenRefresh 文档

在系统确定需要刷新令牌时调用.应用程序应调用getToken()并将令牌发送到所有应用程序服务器.这不会被频繁调用，密钥旋转和处理由于以下原因导致的实例ID更改是必需的:

Called when the system determines that the tokens need to be refreshed. The application should call getToken() and send the tokens to all application servers.This will not be called very frequently, it is needed for key rotation and to handle Instance ID changes due to:

应用程序删除实例ID

App deletes Instance ID

应用已在新设备上还原

用户卸载/重新安装应用程序

User uninstalls/reinstall the app

用户清除应用数据

由于 onTokenRefresh 已被弃用，因此我已根据文档检查了 onNewToken .

As onTokenRefresh has been deprecated, I have checked the onNewToken, As per the documentation

在为默认Firebase项目生成新令牌时调用. 在应用安装后，第一次生成令牌时会调用此方法，如果令牌发生更改，则会再次调用.

Called when a new token for the default Firebase project is generated. This is invoked after app install when a token is first generated, and again if the token changes.

第1季度.如何在有多个发件人ID的情况下知道默认的Firebase项目是什么?

Q1. How to know which is the default Firebase project in case of multiple sender id ?

Q2.假设如果将"authorizedEntity1"与默认的firebase项目关联，那么是否意味着仅在token1更改时才会调用onNewToken?还是在令牌2更改时也会调用它?如果不适用于token2，那么如何知道 token2 需要刷新?

Q2. Suppose if "authorizedEntity1" is associated with the default firebase project then does it mean onNewToken will be invoked only when token1 will be changed ? or it will be also invoked when token2 will be changed? If it doesn't work for token2 then how to know that token2 need to be refreshed?

第三季度.参考此我的理解是，每当需要刷新任何令牌时，onTokenRefresh都会被调用(不仅适用于默认项目).这种理解正确吗?

Q3. With reference of this my understanding is onTokenRefresh will be invoked whenever any of the token needs to be refreshed(not only for default project). Is this understanding correct ?

每当系统确定需要刷新 token1 或 token2 时，我都希望将更新的令牌发送到服务器.

I want to send the updated token to the server whenever system determines that the token1 or token2 need to be refreshed.

注意:我正在处理多个发件人ID时，正在我的应用程序类中初始化firebase.

Note: I am initializing the firebase in my application class as I am dealing with multiple sender ids.

推荐答案

经过测试，我发现只有默认项目的令牌将被传递给onNewToken.通过调用getToken为其他发件人ID创建新令牌时，不会调用onNewToken.

After some test, I found out that only default project's token will be delivered to onNewToken. onNewToken will not be called when new token created for other sender ids by calling getToken.

通过调用getToken API检索的令牌由与默认令牌不同的字符串数据组成.

Tokens retrieved by calling getToken API are consist of different string data than default token.

当默认令牌更改时，不会刷新这些其他发件人ID的令牌. 直到您显式调用deleteToken API为止，它们似乎一直持续到最后. (当我反复调用getToken时，令牌值没有改变.)

And these other sender id's tokens are not refreshed when default token changes. It look like they last until you explicitly call deleteToken API. (Token value didn't changed when I repeatedly call getToken.)
