REACT -调整Google-Cloud-Storage上的图像大小-使用存储桶时出错

Question

我跟随学院的youtube视频去看"Firebase Cloud Functions --上传后调整图像大小“，但我被卡住了，试图用storage.bucket(存储桶)解决一个问题。

这是我面临的错误：

1. (node:2) MetadataLookupWarning: received unexpected error = URL is not defined code = UNKNOWN
2. Error: Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object.

    at onResponse (/srv/node_modules/retry-request/index.js:200:19)
    at PassThrough.<anonymous> (/srv/node_modules/retry-request/index.js:152:11) 

代码：

exports.onFileChange = functions.storage.object().onFinalize((object, context) => {
  // ...
  // Extract object data - left out to focus on the other parts of the function
  const {Storage} = require('@google-cloud/storage');

  // Creates a client
  const storage = new Storage({
      projectId: "dude-garden-care"
  });
  console.log(object, context)
  const bucket = object.bucket;
  const contentType = object.contentType;
  const filePath = object.name;

  if (object.resourceState === 'not_exists') {
    console.log('We deleted a file, exit...')
    return
  }


  if (path.basename(filePath).startsWith('resized-')) {
    console.log('We already renamed that file!')
    return
  }


  const destBucket = storage.bucket(bucket)
  const tmpFilePath = path.join(os.tmpdir(), path.basename(filePath))
  const metadata = { contentType: contentType }
  return destBucket
    .file(filePath)
    .download({
      destination: tmpFilePath,
    })
    .then(() => {
      return spawn('convert', [tmpFilePath, '-resize', '500x500', tmpFilePath])
    })
    .then(() => {
      return destBucket.upload(tmpFilePath, {
        destination: 'resized-' + path.basename(filePath),
        metadata: metadata,
      })
    })
})

非常感谢你们的帮助

我用以下方法解决了这个问题

const admin = require('firebase-admin');
const storage = admin.storage();
const destBucket = storage.bucket(bucket)

希望它能帮助到一些人。
