Using Amazon s3 boto library, how can I get the URL of a saved key?

If the key is publicly readable (as shown above) you can use Key.generate_url:

url = key.generate_url(expires_in=0, query_auth=False)

If the key is private and you want to generate an expiring URL to share the content with someone who does not have direct access you could do:

url = key.generate_url(expires_in=300)

where expires is the number of seconds before the URL expires. These will produce HTTPS url's. If you prefer an HTTP url, use this:

url = key.generate_url(expires_in=0, query_auth=False, force_http=True)

For Boto3, you need to do it the following way...

import boto3

s3 = boto3.client('s3')
url = '{}/{}/{}'.format(s3.meta.endpoint_url, bucket, key)

import boto
from boto.s3.connection import S3Connection

conn = S3Connection('AWS_ACCESS_KEY', 'AWS_SECRET_KEY')

secure_https_url = 'https://{host}/{bucket}/{key}'.format(
    host=conn.server_name(),
    bucket='name-of-bucket',
    key='name_of_key')

http_url = 'http://{bucket}.{host}/{key}'.format(
    host=conn.server_name(),
    bucket='name-of-bucket',
    key='name_of_key')

That's how I did it in boto 2.23.0 for a public URL. I couldn't get the expires_in=None argument to work.

Note that for HTTPS you can't use a subdomain.
