node.js - Firebase 应用程序初始化失败，凭据无效(firebase 函数初始化)

Question

根据 the documentation :

如果您在 Cloud Functions 中使用 Node.js Admin SDK，您可以通过 functions.config() 变量自动初始化 SDK:

admin.initializeApp(functions.config().firebase);

但是当我尝试这段非常简单的代码时:

const functions = require('firebase-functions')
const admin = require('firebase-admin')

admin.initializeApp(functions.config().firebase)

exports.orhub = functions.https.onRequest((req, res) => {
    res.end()
})

我收到以下错误:

error: FIREBASE WARNING: {"code":"app/invalid-credential","message":"Credential implementation provided to initializeApp() via the \"credential\" property failed to fetch a valid Google OAuth2 access token with the following error: \"Error fetching access token: invalid_grant (Bad Request)\". There are two likely causes: (1) your server time is not properly synced or (2) your certificate key file has been revoked. To solve (1), re-sync the time on your server. To solve (2), make sure the key ID for your key file is still present at https://console.firebase.google.com/iam-admin/serviceaccounts/project. If not, generate a new key file at https://console.firebase.google.com/project/_/settings/serviceaccounts/adminsdk."}

我的 Ubuntu 电脑已自动同步日期和时区，所以这不是问题所在。我今天创建了这个项目，所以我得到了最新的模块。

那么，问题是什么？文档中提到的“Cloud Functions”不是和 Firebase 函数一样吗？

我遇到了同样的问题，我是这样解决的:

• 转到 firebase 控制台/设置/服务帐户
• 点击【生成新私钥】选项
• 加载文件到项目

• 实现代码:

  const admin = require('firebase-admin');
  
  var serviceAccount = require('PATH/file_private_key.json');
  
  admin.initializeApp({
      credential: admin.credential.cert(serviceAccount),
      databaseURL: "https://DATA_BASE_URL.firebaseio.com"
  });
