Firebase 相同应用风格的多个项目的云功能

Question

In my app I'm working with multiple Firebase projects because I need my DB to be logically separated by countries.

For that, I'm using FirebaseOptions to access databases from different Firebase projects at runtime.

In addition, on each Firebase project I have the same cloud function, deployed respectively.

The problem is that only the cloud function of the default Firebase project (the one declared in the google-services.json file) is working. It seems that FirebaseOptions doesn't influence the execution of cloud functions.

Anyone has a clue?

• It is important to note that I don't have different flavors per country in my app.

Solution

I could only send notification to registration tokens that were associated for a particular sender ID. Basically, I was trying to send to tokens that belonged to other project.

To do this, I should have allowed multiple projects to send messages to the same client app. To enable this feature, we need to make sure we have each project's sender ID. When requesting registration, the client app fetches the token multiple times, each time with a different sender ID in audience field, using the token retrieval method.

In other terms, we'll have to call getToken() passing the sender ID and simply "FCM" (eg getToken("2xxxxx3344", "FCM")) as the parameters. Also make sure that you call this for each sender (project) that you need.

Sounds like a problem in your build variants.

If im right. You can use env-variables and >firebase use (cli command) to controll your builds.

Initilize FireBase-Admin-SDK.

A first Idea of how to import different cred.json files.

import serviceAccountProd = require("./prodCred.json");
import serviceAccountDev = require("./devCred.json");

admin.initializeApp({
  credential: admin.credential.cert(
  development ? (serviceAccountDev as admin.ServiceAccount) : (serviceAccountProd as admin.ServiceAccount)),
  databaseURL: database,
  storageBucket: bucket,
});

i didnt implemented it fully - feel free to edit
