Question

这是我的职责

app.post("/pet", upload.single('file'), async (req, res, next) => {
  if(!req.file) {
    res.status(400).send('No file uploaded')
  }
  const blob = petAdoptionBucket.file(req.file.originalname)
  const blobStream = blob.createWriteStream()
  blobStream.on('error', err => {
    next(err)
  })

  blobStream.on('finish', () => {
    const publicUrl = format(
      `https://storage.googleapis.com/${petAdoptionBucket.name}/${blob.name}`
    );
    res.status(200).send(publicUrl);
  });

  blobStream.end(req.file.buffer)
})

在功能工作和文件会出现在我的GCS桶，但我有一个500内部服务器错误称的路径名应该是一个对象，而不是一个字符串。（关于在blobStrea.on publicUrl变量（））

有人可以告诉我为什么？

下面是，我发现了错误

找到了。 publicUrl 是 format() 所以它需要一个对象而不是字符串

publicUrl = format(
`https://storage.googleapis.com/${petAdoptionBucket.name}/${blob.name}`
)

，我用过

publicUrl = format({
path: `https://storage.googleapis.com/${petAdoptionBucket.name}/${blob.name}`
})

奇怪的错误时，上传文件到谷歌云存储Multer
