Google 云/Firebase 存储错误：如果没有“client_email”，则无法签署数据。...名称：'签名错误'

Question

我试图从 firebase/gc 存储中的文件中获取signedurl。我能找到的所有其他解决方案是创建一个服务帐户，下载服务密钥，然后在我的应用程序中使用它，但我这样做了，但仍然收到错误。我也遵循了这个建议，并使用 Firebase getSignedUrl() 将相关角色添加到我的服务帐户 SigningError中。

client_email 属性位于我使用的服务密钥中。

对于服务帐户和 gc 来说相当新，所以我可能会错过一些简单的东西。

我能够列出存储桶，并且对 cloud firestore 的所有其他请求都在工作。事实证明，它只是特定文件的签名 URL 很难检索。

让我有点疯狂，所以任何帮助都会很棒。

这是我的代码。

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const express = require('express');
const { ApolloServer, gql } = require('apollo-server-express');
const { Storage } = require('@google-cloud/storage');

const serviceAccount = require('./emom-84ee4-firebase-adminsdk-2309z-aab93226ec.json');
const keyfileName = require('./emom-84ee4-ac9e94667d5e.json');

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://emom-84ee4.firebaseio.com"
});

const storage = new Storage({
    projectId: 'emom-84ee4',
    keyFileName: keyfileName,
    // TRIED THIS ALSO => keyFileName: serviceAccount
});

const typeDefs = gql`
    type DownloadURL {
        url: String
    }

    type Comment {
        artist: String,
        comment: String,
        userId: String,
        replies: [Comment]
    }

    type Track {
        album: String,
        artist: String,
        artistId: String,
        description: String,
        genre: String,
        id: ID,
        title: String,
        duration: Int,
        comments: [Comment]
    }
    type User {
        artist: String,
        artistImageUrl: String,
        artistName: String,
        bio: String,
        location: String,
        userId: String,
        website: String
    }
    type Query {
        tracks: [Track]
        users: [User]
        downloadUrl: DownloadURL
    }
`

const resolvers = {
    Query: {
        async tracks() {
            const tracks = await admin
            .firestore()
            .collection('tracks')
            .get();
        return tracks.docs.map(track => track.data());
    },
    async users() {
        const users = await admin
            .firestore()
            .collection('users')
            .get();
            return users.docs.map(user => user.data());
    },
    // ISSUE HAPPENING HERE
    async downloadUrl() {
        try {
            const signedUrl = await storage
                .bucket('emom-84ee4.appspot.com')
                .file('tracks/ds5MaDn5ewxxvV0CK9GG.mp3')
                .getSignedUrl({ action: 'read', expires: '10-25-2022' });
            const url = signedUrl;
            console.log(url)
            return url;
        } catch (error) {
            console.error(error);
        }
    }
    }
}

const app = express();
const server = new ApolloServer({ typeDefs, resolvers });

server.applyMiddleware({ app, path: '/', cors: true });

exports.graph = functions.https.onRequest(app);

运行时出现“无法在没有数据的情况下签名client_email”错误firebase emulators:start。

我通过设置服务帐户并将服务帐户 .json 凭据文件下载为service_account.json，然后运行来修复此问题GOOGLE_APPLICATION_CREDENTIALS="service_account.json" firebase emulators:start
