无法使用 angularfire2 在 Angular 6 应用程序中访问多个 Google Firestore 数据库 [英] Can not have access to multiple Google Firestore DB in Angular 6 application with angularfire2

问题描述

我尝试通过 angularfire2 包从我的 Angular 6 应用程序访问多个 Google Firestore 数据库.

I try to have access to multiple Google Firestore DB from my Angular 6 application through angularfire2 package.

我在 app.module.ts 中初始化了多个 AngularFireModule 实例，但找不到访问两个数据库的方法:

I initialized multiple instance of AngularFireModule in app.module.ts but couldn't find a way to have access to both DBs:

  @NgModule({
  declarations: [
	...
  ],
  imports: [
	...
    AngularFireModule.initializeApp(coolStoreConfig, 'coolStore'),
    AngularFireModule.initializeApp(perfectStoreConfig, 'perfectStore'),
	...
  ],
  ...
 })

有什么想法吗?

推荐答案

经过一番搜索，以下answer 可以提供很多帮助:angular2firebase - 使用 Angular 6 的多个实例

After some searches around, the following answer could help a lot: angular2firebase - multiple instances using Angular 6

看起来为每个实例创建提供程序是个好主意

looks like creating providers for each instance can be a good idea

...
{ provide: AngularfirestoreCoolStoreService, deps: [PLATFORM_ID, NgZone], useFactory: AngularfirestoreCoolStoreFactory },
{ provide: AngularfirestorePerfectStoreService, deps: [PLATFORM_ID, NgZone], useFactory: AngularfirestorePerfectStoreFactory }
...
