node.js - 如何使用nodejs将图像上传到s3时设置到期日期

Question

我想在nodejs sdk中上传图像/视频并设置到期日期。 谁能告诉我如何在将图像上传到 s3 时设置到期日期？

Answer 1

You can use multer-s3 middleware for express, and then you can configure the headers that you want by providing the Expires, Cache-Control headers.

const upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: 'some-bucket',
    contentType: multerS3.AUTO_CONTENT_TYPE,
    expires: 'Wed, 21 Oct 2020 07:28:00 GMT',
    key: function (req, file, cb) {
      cb(null, Date.now().toString())
    }
  })
})


app.post('/upload', upload.array('photos', 3), function(req, res, next) {
  res.send('Successfully uploaded ' + req.files.length + ' files!')
})
