Question

我正尝试使用Firebase云功能和firebase-admin组合来为向auth中的用户添加auth声明的路径。我正在用firebase serve对其进行测试，并且尝试使用以下代码进行此操作：

    <script>
var myreset = [21,37,00]; // at what time to reset - 19:40:00

var mycountdown = startCountdown();

function startCountdown(){
    var enddate = calculateEndDate();
  return setInterval(function(){tickTock(calculateStartDate(),enddate)}, 1000);
}
function calculateStartDate(){ //this needs to be edited if using the server time
    return new Date();
}
function calculateEndDate(){
    var enddate = new Date();
    enddate.setHours(myreset[0]);
    enddate.setMinutes(myreset[1]);
    enddate.setSeconds(myreset[2]);
    return enddate;
}
function tickTock(startdate, enddate){
  var diff = enddate.getTime() - startdate.getTime(); 
  d = diff >= 0 ? diff : diff + 24*3600*1000;
  var h = Math.floor(d / 3600 / 1000);
  var m = Math.floor(d / 60 / 1000) - 60*h; 
  var s = Math.floor(d / 1000) - 3600*h - 60*m; 
  printCountdown(h,m,s);
}
function pluralize(word,count){
      return (count > 1) ? word+'s ' : word+' ';
}
function printCountdown(h,m,s){
  var t = h + pluralize(' hour',h)+ m+pluralize(' minute',m)+ s + pluralize(' and second',s);
  $('#mycountdown').html(t); 
}
</script>

那实际上不起作用，并且给了我下面的错误：

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!");
});

有一篇博客文章说，如果我想通过firebase-admin使用除firestore和实时数据库以外的任何东西，我必须做一些额外的配置，所以我尝试通过使用以下代码来测试firestore是否正常工作：

{ 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. Error code: ENOTFOUND".

>    codePrefix: 'app' }

再次给我一个与管理员凭据本身有关的错误：

// 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")
});

和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:\Users\jishn\WorkSpace\Works\Status\firebase\functions\node_modules\google-auth-library\build\src\auth\googleauth.js:159:19) > at process._tickCallback (internal/process/next_tick.js:68:7)返回functions.config()

无论发生什么情况，命令firebase服务都处于关闭状态。 下面的代码适用于serviceAccount.json文件：

{}

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：

通过一些老问题，我相信这在＃2214的8.5.0版本中已解决

解决方案如下：

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

firebase-functions上的firebase-admin无法正确初始化App
