我正在尝试使用Firebase管理器在Node.js v8.4.0上使用Firebase管理功能访问Firestore在使用firebase功能本地运行的Firebase Cloud 功能：Windows 10上的shell .

firebase -v 4.2.1

"dependencies": {
    "firebase-admin": "^6.0.0",
    "firebase-functions": "^2.0.5"
  }

尝试从我的应用程序代码使用firebase管理员后，我尝试在https://github.com/firebase/functions-samples/blob/master/quickstarts/uppercase-firestore/functions/index.js中运行快速启动示例 .

这是实际的代码运行：

'use strict';

// [START all]
// [START import]
// 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({})
// [END import]

// [START addMessage]
// Take the text parameter passed to this HTTP endpoint and insert it into the
// Realtime Database under the path /messages/:documentId/original
// [START addMessageTrigger]
exports.addMessage = functions.https.onRequest((req, res) => {
// [END addMessageTrigger]
  // Grab the text parameter.
  const original = req.query.text;
  // [START adminSdkAdd]
  // Push the new message into the Realtime Database using the Firebase Admin SDK.
  return admin.firestore().collection('messages').add({original: original}).then((writeResult) => {
    // Send back a message that we've succesfully written the message
    return res.json({result: `Message with ID: ${writeResult.id} added.`});
  });
  // [END adminSdkAdd]
});
// [END addMessage]

// [START makeUppercase]
// Listens for new messages added to /messages/:documentId/original and creates an
// uppercase version of the message to /messages/:documentId/uppercase
// [START makeUppercaseTrigger]
exports.makeUppercase = functions.firestore.document('/messages/{documentId}')
    .onCreate((snap, context) => {
// [END makeUppercaseTrigger]
      // [START makeUppercaseBody]
      // Grab the current value of what was written to the Realtime Database.
      const original = snap.data().original;
      console.log('Uppercasing', context.params.documentId, original);
      const uppercase = original.toUpperCase();
      // You must return a Promise when performing asynchronous tasks inside a Functions such as
      // writing to the Firebase Realtime Database.
      // Setting an 'uppercase' sibling in the Realtime Database returns a Promise.
      return snap.ref.set({uppercase}, {merge: true});
      // [END makeUppercaseBody]
    });
// [END makeUppercase]
// [END all]

但是，我仍然得到权限被拒绝错误 .

这是我得到的输出：

firebase > makeUppercase({original:'alphabets'},{params:{documentId:'mydoc'}})
'Successfully invoked function.'
firebase > info: User function triggered, starting execution
info: Uppercasing mydoc alphabets
info: Function crashed

  code: 7,

我的安全规则是完全开放的，但没有解决错误 .

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write;
    }
  }
}

我还认为这可能是一个身份验证问题，所以我尝试了以下内容来初始化应用程序：

1

admin.initializeApp()

2

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

3

var serviceAccount = require('path/to/serviceAccountKey.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: 'https://<DATABASE_NAME>.firebaseio.com'
});

最后一个用我自己的凭证文件和项目配置 . 所有这些尝试仍然给我缺少权限错误 .

Update: 我将这些功能部署到 Cloud 端，它们似乎运行正常，但在本地运行时，我仍然遇到错误：7权限被拒绝 .

Update 2: 根据@Doug Stevenson的建议，使用 gcloud auth application-default login 设置应用程序默认凭据 . 未设置确保的环境变量GOOGLE_APPLICATION_CREDENTIALS . 试图在上面的1,2和3以及下面的4中的代码没有成功 . 遇到了同样的错误 .

4

admin.initializeApp({
    credential: admin.credential.applicationDefault(), 
    databaseURL: "https://myapp-redacted.firebaseio.com"
  });
