Generate signed URL's for S3 objects from the command line (requires .boto file for credentials)

signed_url.py

#!/usr/bin/env python3

import boto3, argparse

parser = argparse.ArgumentParser()
parser.add_argument('-b','--bucket', help='Name of your S3 Bucket', required=True)
parser.add_argument('-o','--object', help='Name of the object + prefix in your bucket', required=True)
parser.add_argument('-t','--time', type=int, help='Expirery in seconds Default = 60', default=60)
args =  vars(parser.parse_args())


def get_signed_url(time, bucket, obj):
    s3 = boto3.client('s3')

    url = s3.generate_presigned_url('get_object', Params = { 'Bucket': bucket, 'Key': obj }, ExpiresIn = time)
    return url

try:
    url = get_signed_url(args['time'],args['bucket'], args['object'])
    print(url)
except:
    print('Something odd happened')

Updated for boto3 and python3 👯‍♂️
