问题 I am using NodeJs to upload files to AWS S3. I want the client to be able to download the files securely. So I am trying to generate signed URLs, that expire after one usage. My code looks like this: Uploading const s3bucket = new AWS.S3({ accessKeyId: 'my-access-key-id', secretAccessKey: 'my-secret-access-key', Bucket: 'my-bucket-name', }) const uploadParams = { Body: file.data, Bucket: 'my-bucket-name', ContentType: file.mimetype, Key: `files/${file.name}`, } s3bucket.upload(uploadParams,
