Question

我一直在尝试将一些图片上传到我的firebase存储桶。我遵循了这个官方文档： -

https://firebase.google.com/docs/storage/admin/start

和https://googlecloudplatform.github.io/google-cloud-node/#/docs/storage/latest/storage/bucket

我能够看到存在于存储桶中的文件（这些文件使用Android应用程序存储在那里）

但是我无法从nodejs的admin.storage模块上传本地文件。

以下是代码：

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://myprojectid.firebaseio.com/" , 
  storageBucket : "myprojectid.appspot.com/"
});

bucket = admin.storage().bucket() ; 
bucket.upload('./mylocalfile.jpg' , (err , file , response)=>{
console.log(err) ; //always gives me err
console.log(file) ; //gives undefined
}) ;

但bucket.getFiles().then(objects=>console.log(objects)) ;完美无缺，并打印出根目录中的文件。

如何解决这个问题？

以下是控制台记录error时打印的err：

不幸的是，'upload'函数只接收本地文件或url的路径，因此在实现云功能上传文件REST api时会造成一些复杂性。我猜这不应该是将文件上传到云功能服务器并将本地文件上传到云存储的正确方法。

以下是我使用multer从请求获取文件，然后将其转换为数据并使用保存功能上传来完成上传端点到firebase（gcloud）存储的成就。

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const express = require('express');
const multer  = require('multer');
const app = express();
const fileUpload = multer();

admin.initializeApp(.......);

/*
 * Upload File
 **/
app.post('/', fileUpload.single('file'), functions.https.onRequest((req, res) => {
  const file = req.file;
  const bucket = admin.storage().bucket();
  const name = file.originalname;
  
  const bucketFile = bucket.file(name);

  bucketFile
    .save(new Buffer(file.buffer))
    .then(() => {
      res.status(200).json({
        status: 'success',
        data: Object.assign({}, bucketFile.metadata, {
          downloadURL: `https://storage.googleapis.com/${bucket.name}/${name}`,
        })
      });
    })
    .catch(err => {
      res.status(500).json({
        status: 'error',
        errors: err,
      });
    });
}));

这是我的POSTMAN测试屏幕。

如果您需要进一步的帮助，请告诉我。
