FetchError，原因：读取ECONNRESET； 将图片从 node.js 上传到谷歌云存储时

Question

I am using node version 13.5.0. Google cloud storage gives an error named "FetchError, reason: read ECONNRESET" when trigger to upload. I parsed the images by multer@1.4.2 with express@4.17.1. I also created the bucket and service account correctly. Here is code:

const storage = new Storage({
     projectId: 'ultra-brand-263520',
     keyFilename: './google.json',
   });
   const bucketName = 'chimaera-img';
   const bucket = storage.bucket(bucketName);
   const gcsFileName = `${Date.now()}-${req.file.originalname}`;
   const file = bucket.file(gcsFileName);

   const stream = file.createWriteStream({
     metadata: {
       contentType: req.file.mimetype,
     },
   });

   stream.on('error', (err) => {
     req.file.cloudStorageError = err;
     // next(err);
     console.log(err)
   });

   stream.on('finish', () => {
     req.file.cloudStorageObject = gcsFileName;

     file.makePublic()
       .then(() => {
         req.file.gcsUrl = gcsHelpers.getPublicUrl(bucketName, gcsFileName);
         // next();
         console.log(req.file.gcsUrl)
       });
   });

   stream.end(req.file.buffer);

and the error is:

As John Hanley pointed out you are not creating a read stream so you're not uploading any data. Furthermore the preferable way to upload a file to Cloud Storage is through the function upload() which happens to be a convenient wrapper around createWriteStream.

I suggest you try to follow the sample code for uploading a file given in the official documentation . Additionally if you want to know further about the functions and how-to of this client library you might take a look at the Nodejs reference forupload and createWriteStream .
