Firebase-Functions 上的 firebase-admin 无法正确初始化应用

Question

我试图使用 firebase cloud 函数和 firebase-admin 组合来为在身份验证中向我的用户添加身份验证声明提供一条路由。 我正在使用火力服务对其进行测试，并尝试了以下代码：

const functions = require('firebase-functions');
const admin = require("firebase-admin");
admin.initializeApp(functions.config().firebase);
const func = () => {
admin.auth().setCustomUserClaims("(req.params.uid", {isActivated: true}).then(() => {
console.log("Done")
})
.catch(e => console.error(e))
}
setTimeout(func, 4000)

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
exports.api = functions.https.onRequest((request, response) => {
console.log(functions.config())
response.send("Hello from Firebase!");
});

这实际上不起作用，并给了我以下错误：

{ Error: 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: Error while making request: getaddrinfo ENOTFOUND metadata.google.internal metadata.google.internal:80.

一篇博客文章说，如果我想将firestore和实时数据库以外的任何东西与firebase-admin一起使用，我必须做一些额外的配置，所以我尝试使用以下代码测试firestore是否正常工作：

// The Cloud Functions for Firebase SDK to create Cloud Functions and setup triggers.
const functions = require('firebase-functions');
// The Firebase Admin SDK to access the Firebase Realtime Database.
const admin = require('firebase-admin');
admin.initializeApp();
exports.api = functions.https.onRequest((req, res) => {
var db = admin.firestore();
db.collection('users').get()
.then(snapshot => {
snapshot.forEach(doc => {
console.log(doc.id, '=>', doc.data());
});
})
.catch(err => {
console.log('Error getting documents', err);
}); 
res.send("Hi")
});

它再次给了我另一个与管理员凭据本身相关的错误：

Error getting documents Error: Could not load the default credentials. Browse to https://cloud.google.com/docs/authentication/getting-started for more information.
>      at GoogleAuth.getApplicationDefaultAsync (C:UsersjishnWorkSpaceWorksStatusfirebasefunctionsnode_modulesgoogle-auth-librarybuildsrcauthgoogleauth.js:159:19)
>      at process._tickCallback (internal/process/next_tick.js:68:7)

和functions.config()回报{}

无论发生什么，都会在命令火力基地服务上。下面的代码适用于serviceAccount.json文件：

admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://status-kgi.firebaseio.com"
});

但是我认为必须对云功能使用这种管理员初始化并不是一个好主意。

从 Github 问题解决：

查看一些旧问题，我相信这已在 #8.5.0 版本中由 #2214 修复

解决方案如下：

const admin = require('firebase-admin');
admin.initializeApp(); // no neeed for functions.config().firebase
