java获取s3对象url,Python 3 Boto 3，AWS S3：获取对象URL

I need to retrieve an public object URL directly after uploading a file, this to be able to store it in a database.

This is my upload code:

s3 = boto3.resource('s3')

s3bucket.upload_file(filepath, objectname, ExtraArgs={'StorageClass': 'STANDARD_IA'})

I am not looking for a presigned URL, just the URL that always will be publicly accessable over https.

Any help appreciated.

There's no simple way but you can construct the URL from the region where the bucket is located (get_bucket_location), the bucket name and the storage key:

bucket_name = "my-aws-bucket"

key = "upload-file"

s3 = boto3.resource('s3')

bucket = s3.Bucket(bucket_name)

bucket.upload_file("upload.txt", key)

location = boto3.client('s3').get_bucket_location(Bucket=bucket_name)['LocationConstraint']

url = "https://s3-%s.amazonaws.com/%s/%s" % (location, bucket_name, key)
