如何获取Firebase实时数据库AuthToken

Question

我从一个开发人员那里得到了一个基于Firabase Realtime DB的Ionic应用程序的代码。当尝试启动应用程序时，im会收到此错误消息。

[ng]src/app/data-service.service.ts（14,36）中出现错误：错误TS2339:类型“{apikey：String；authDomain：String；databaseUrl：String；ProjectId：String；StorageBucket：String；MessagingSenderId：String；}”上不存在属性“auth token”。

不幸的是，我想不出如何从FireBase获得authToken。

数据-service.service.ts

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { environment  } from '../environments/environment';
import * as firebase from 'firebase/app';


@Injectable({
  providedIn: 'root'
})
export class DataServiceService {
  userId: any;
  userName: any;
  databaseUrl = environment.firebase.databaseURL;
  authToken = environment.firebase.authToken;

  constructor(private http: HttpClient) {
    console.log('Hello DataServiceService Provider');
    console.log(this.databaseUrl);
    console.log(this.authToken);
    this.userId = localStorage.getItem('userId');
    if (!localStorage.getItem('currentUserShift')) {
      localStorage.setItem('currentUserShift', JSON.stringify({ periods: {} }));
    }
    if (!localStorage.getItem('pendingShifts')) {
      localStorage.setItem('pendingShifts', JSON.stringify([]));
    }
  }

  setUserId(userId) {
    console.log('setUserId ');
    this.userId = userId;
    localStorage.setItem('userId', userId);
  }

  getUserId() {
    return this.userId;
  }

  getUserName() {
    return this.userName;
  }

  setUserName(userName) {
    this.userName = userName;
  }

  updateLocalCurrentUserShift(currentUserShift) {
    localStorage.setItem('currentUserShift', JSON.stringify(currentUserShift));
  }

  getLocalCurrentUserShift() {
    return JSON.parse(localStorage.getItem('currentUserShift'));
  }

  async insertUserCurrentShiftToPendingShifts(currentShift) {
    const pendingShifts = JSON.parse(localStorage.getItem('pendingShifts'));
    pendingShifts.push(currentShift)
    localStorage.setItem('pendingShifts', JSON.stringify(pendingShifts));
    this.updateLocalCurrentUserShift({ periods: {} });
    await this.insertPendingShiftsToFirebase();
    // localStorage.setItem('currentUserShift', JSON.stringify({}));
  }

  async insertPendingShiftsToFirebase() {
    const pendingShifts = JSON.parse(localStorage.getItem('pendingShifts'));
    console.log('pendingShifts:', pendingShifts);
    const failedToBeSentPendingShifts = [];
    for (let i = 0 ; i < pendingShifts.length ; i++) {
      try {
        const key = await this.insertUserCurrentShifttoHistory(pendingShifts[i]);
        console.log('key' , key);
      } catch (err) {
        console.log('Error while inserting into firebase', JSON.stringify(err));
        failedToBeSentPendingShifts.push(pendingShifts[i]);
      }
    }
    localStorage.setItem('pendingShifts', JSON.stringify(failedToBeSentPendingShifts));
    return true;

Environment.Prod.ts

export const environment = {

export const environment = {

我找到了这样的方法：

firebase.auth().currentUser.getIdToken(/* forceRefresh */ 
true).then(function(idToken) {
  // Send token to your backend via HTTPS
  // ...
}).catch(function(error) {
  // Handle error
});
