Firebase功能1.0.0迁移:使用Google服务帐户凭据

我刚从beta(v0.9.1)更新到v1.0.0,并在初始化时遇到了一些问题。根据{{​​3}},functions.config().firebase现已弃用。这是我之前的初始化:

const serviceAccount = require('../service-account.json')

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: functions.config().firebase.databaseURL,
  storageBucket: functions.config().firebase.storageBucket,
  projectId: functions.config().firebase.projectId,
})

以下是我在升级后将其更改为:

admin.initializeApp()

首先,这似乎工作正常,dataURL和storageBucket正在被识别。但是,新缺少的credential字段存在问题。该字段是访问Google云端存储所必需的。我在我的应用中访问了@google-cloud/storage API,如下所示:

import { Bucket, File } from '@google-cloud/storage'
import * as admin from 'firebase-admin'

bucket: Bucket = admin.storage().bucket()

    this.bucket
      .upload(filepath, {
        destination: uploadPath,
      })
      .then((fileTuple: [File]) => {
        // after uploading, save a reference to the audio file in the DB
        fileTuple[0]
          .getSignedUrl({ action: 'read', expires: '03-17-2025' })
          .then((url: [string]) => {
            dbRef.child('audioFiles').push(url[0])
          })
          .catch(err => console.log('Error:', err))

        console.log(`${filepath} uploaded to ${this.bucket.name}.`)
      })

这会将文件上传到存储,然后将签名的URL插入我的实时数据库。

迁移后,这段代码会出现以下错误:

SigningError: Cannot sign data without `client_email`

由于client_emailservice-account.json上的一个字段,我怀疑我需要重新插入credentials,如下所示:

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
})

但是,当我尝试此操作时,会出现Error: Can't determine Firebase Database URL.Error: Bucket name not specified or invalid.等错误。因此,如果我手动插入credential,则似乎也会手动插入databaseURLstorageBucket

所以问题是,我该怎么做?

答案 0 :(得分:5)

自己想出来。我必须像这样重写我的初始化调用:

const serviceAccount = require('../service-account.json')
const firebaseConfig = JSON.parse(process.env.FIREBASE_CONFIG)

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: firebaseConfig.databaseURL,
  storageBucket: firebaseConfig.storageBucket,
  projectId: firebaseConfig.projectId,
})
