将文件放置到Golang中的Amazon S3后，如何获取文件URL？

Question

File is uploaded successfully, and I want to return file url after uploading.

_, err := s3.New(s).PutObject(&s3.PutObjectInput{
    Bucket:               aws.String("bucket"),
    Key:                  aws.String(tempFileName),
    ACL:                  aws.String("public-read"), // could be private if you want it to be access by only authorized users
    Body:                 bytes.NewReader(buffer),
    ContentLength:        aws.Int64(int64(size)),
    ContentType:          aws.String(http.DetectContentType(buffer)),
    ContentDisposition:   aws.String("attachment"),
    ServerSideEncryption: aws.String("AES256"),
    StorageClass:         aws.String("INTELLIGENT_TIERING"),
})

I have checked amazon doc for PutObject function, but PutObjectOutput struct type But there is no uploaded file url in this structure.

How can I get file url? Is there other way to return uploaded file url in amazon s3 sdk as soon as upload success?

Thanks

You can construct the URL as:

https://BUCKETNAME.s3-REGIONNAME.amazonaws.com/KEY

For example:

https://my-bucket.s3-ap-southeast-2.amazonaws.com/foo/bar.txt
