是否可以将连接的字符串转换为AngularFire的查询？

import { AngularFireModule } from '@angular/fire';
import { AngularFireDatabase } from '@angular/fire/database';

// ...

export class YourServiceOrComponent {
  constructor(private afDatabase: AngularFireDatabase) {
    const config = {
      // 这里替换为你的连接字符串
      databaseURL: 'your-connection-string'
    };

    const app = AngularFireModule.initializeApp(config);
    const db = afDatabase.database(app);
  }
}

export class YourServiceOrComponent {
  constructor(private afDatabase: AngularFireDatabase) {
    // ...

    const itemsRef = db.list('items');
    itemsRef.valueChanges().subscribe(items => {
      console.log(items);
    });
  }
}
