不使用google-services.json支持多个项目的FirebaseMessaging [英] FirebaseMessaging without using google-services.json to support multiple projects

问题描述

我知道能够使用自定义选项创建命名的 FirebaseApp 实例以与例如 FirebaseDatabase 一起使用的功能，但是我特别需要能够使用 FirebaseMessagaging 针对不同的(在运行时确定的)Firebase项目.

I am aware of the ability to create a named FirebaseApp instance with custom options for use with, for example, FirebaseDatabase, but I specifically need the ability to use FirebaseMessagaging against different (determined at runtime) Firebase projects.

我遇到的问题是 FirebaseMessaging.getInstance()不支持name参数.

The problem I have is that FirebaseMessaging.getInstance() doesn't support the name argument.

这有可能吗?

我需要支持单独的项目的原因是我们的客户端连接到不同的客户服务器，因此每个客户都将拥有自己的firebase帐户并生成自己的通知.

The reason I need to support separate projects is that our client connects to different customers server, so each customer will have their own firebase account and be generating their own notifications.

如果不可能，是否有任何方法可以将一个客户与另一个客户隔离开，因此他们不可能将通知发送到另一位客户的设备(假设他们可以某种方式获得有效的目标设备令牌)?

If it is not possible, is there any way to isolate one customer from another, so they can't possibly send notifications to another customer's device (assuming they could obtain a valid target device token in some way)?

推荐答案

The Firebase Blog contains a post about this exact issue, and provides a guide for how to handle it.

博客文章描述了两个步骤:

The blog post describes two steps:

1. 禁用FirebaseInitProvider

将其添加到AndroidManifest.xml以禁用默认初始化代码:

Add this to the AndroidManifest.xml to disable the default initialization code:

<provider
  android:name="com.google.firebase.provider.FirebaseInitProvider"
  android:authorities="${applicationId}.firebaseinitprovider"
  tools:node="remove"
  />

1. 致电FirebaseApp.initializeApp(Context，FirebaseOptions)

准备好必要的配置后，请使用以下命令自行初始化Firebase:

As soon as you have the necessary configuration ready, initialize Firebase on your own with:

FirebaseOptions.Builder builder = new FirebaseOptions.Builder()
  .setApplicationId("1:0123456789012:android:0123456789abcdef")
  .setApiKey("your_api_key")
  .setDatabaseUrl("https://your-app.firebaseio.com")
  .setStorageBucket("your-app.appspot.com");
FirebaseApp.initializeApp(this, builder.build());

Google服务插件文档描述了如何获取值您需要使用JSON:

The Google Services Plugin documentation describes how to get the values you need from the JSON:

{YOUR_CLIENT} 是 client 对象，其中包含与您的软件包名称(应用程序ID)相匹配的 client_info/android_client_info/package_name .

{YOUR_CLIENT} is the client object that contains a client_info/android_client_info/package_name that matches your package name (application id).

google_app_id: {YOUR_CLIENT}/client_info/mobilesdk_app_id

google_app_id: {YOUR_CLIENT}/client_info/mobilesdk_app_id

gcm_defaultSenderId: project_info/project_number

gcm_defaultSenderId: project_info/project_number

default_web_client_id: {YOUR_CLIENT}/oauth_client/client_id(client_type == 3)

default_web_client_id: {YOUR_CLIENT}/oauth_client/client_id (client_type == 3)

ga_trackingId: {YOUR_CLIENT}/services/analytics-service/analytics_property/tracking_id

ga_trackingId: {YOUR_CLIENT}/services/analytics-service/analytics_property/tracking_id

firebase_database_url: project_info/firebase_url

firebase_database_url: project_info/firebase_url

google_api_key: {YOUR_CLIENT}/api_key/current_key

google_api_key: {YOUR_CLIENT}/api_key/current_key

google_crash_reporting_api_key: {YOUR_CLIENT}/api_key/current_key

google_crash_reporting_api_key: {YOUR_CLIENT}/api_key/current_key
