当在服务器上使用firebase库时，你通常会授权using a service account，因为这会给予你对实时数据库的管理员访问权限。你可以使用同一个服务帐户的凭证文件来授权gcloud。
顺便说一下：Firebase项目本质上也是Google Cloud Platform项目，您可以在https://console.firebase.google.com、https://console.cloud.google.com和https://console.developers.google.com上访问您的Firebase项目您可以在Firebase Console > Project Settings或Cloud Console Dashboard上查看您的项目ID
在使用gcloud SDK时，请确保您使用的存储桶与Firebase Storage使用的存储桶（已经存在）相同。您可以在Firebase web config对象或Firebase Storage选项卡中找到存储桶名称。基本上，您的代码应该如下所示：

var gcloud = require('gcloud');

var storage = gcloud.storage({
  projectId: '<projectID>',
  keyFilename: 'service-account-credentials.json'
});

var bucket = storage.bucket('<projectID>.appspot.com');

...

Firebase存储现在受NodeJS的管理SDK支持：
https://firebase.google.com/docs/reference/admin/node/admin.storage

// Get the Storage service for the default app
var defaultStorage = firebaseAdmin.storage();
var bucket = defaultStorage.bucket('bucketName');
...

Firebase Admin SDK允许您直接访问Google云存储。
有关详细信息，请访问Introduction to the Admin Cloud Storage API

var admin = require("firebase-admin");
var serviceAccount = require("path/to/serviceAccountKey.json");

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    storageBucket: "<BUCKET_NAME>.appspot.com"
});

var bucket = admin.storage().bucket();

bucket.upload('Local file to upload, e.g. ./local/path/to/file.txt')

我希望它会对你有用。我上传了一个文件从本地，然后我添加了访问令牌使用UUID后，我上传到firebase存储。有后，我生成下载网址。如果我们点击生成网址，它会自动下载一个文件。

const keyFilename="./xxxxx.json"; //replace this with api key file
    const projectId = "xxxx" //replace with your project id
    const bucketName = "xx.xx.appspot.com"; //Add your bucket name
    var mime=require('mime-types');
    const { Storage } = require('@google-cloud/storage');
    const uuidv1 = require('uuid/v1');//this for unique id generation

   const gcs = new Storage({
    projectId: projectId,
    keyFilename: './xxxx.json'
     });
    const bucket = gcs.bucket(bucketName);

    const filePath = "./sample.odp";
    const remotePath = "/test/sample.odp";
    const fileMime = mime.lookup(filePath);

//we need to pass those parameters for this function
    var upload = (filePath, remoteFile, fileMime) => {

      let uuid = uuidv1();

      return bucket.upload(filePath, {
            destination: remoteFile,
            uploadType: "media",
            metadata: {
              contentType: fileMime,
              metadata: {
                firebaseStorageDownloadTokens: uuid
              }
            }
          })
          .then((data) => {

              let file = data[0];

              return Promise.resolve("https://firebasestorage.googleapis.com/v0/b/" + bucket.name + "/o/" + encodeURIComponent(file.name) + "?alt=media&token=" + uuid);
          });
    }
//This function is for generation download url    
 upload(filePath, remotePath, fileMime).then( downloadURL => {
        console.log(downloadURL);

      });

注意gcloud已经过时了，请使用google-cloud。你可以在项目设置-〉服务帐户中找到SERVICE_ACCOUNT_KEY_FILE_PATH。

var storage = require('@google-cloud/storage');

var gcs = storage({
    projectId: PROJECT_ID,
    keyFilename: SERVICE_ACCOUNT_KEY_FILE_PATH
  });

// Reference an existing bucket.
var bucket = gcs.bucket(PROJECT_ID + '.appspot.com');

...

或者你可以像这样简单地用聚合物填充XmlHttpRequest-

const XMLHttpRequest = require("xhr2");
global.XMLHttpRequest = XMLHttpRequest

并导入

require('firebase/storage');

就是这样，所有firebase.storage()方法现在都应该可以工作了。

我已经实现了将文件上传到firebase存储器的API：

const fs = require('firebase-admin');
const app = require('express')();
const serviceAccount = require('./serviceAccountKey_DEV.json');

fs.initializeApp({
    credential: fs.credential.cert(serviceAccount),
    storageBucket: `${serviceAccount.project_id}.appspot.com`
});

// Upload the file on firebase storage
app.get("/upload-on-firebase", async (req, res, next) => {
    var bucket = fs.storage().bucket();
    const result = await bucket.upload('data.json');
    console.log('result :', result);
    return res.send(result);
});

调用API上传：

curl --location --request GET 'http://localhost:3000/upload-on-firebase'
