Presign a URL in S3 using boto3

presign-s3.py

#!/usr/local/bin/python3

# To use this snippet:
# Create a bucket and upload a private file into it beforehand.
# To make the private file shareable for a fixed number of seconds
# you can "presign" the URL, which creates an expiring hashed URL.
# You can then distribute that URL to other systems or coleagues.

import boto3

bucket = "BUCKET_NAME"     # replace with actual bucket name
file_path = "FILE_PATH"    # could be "file.txt" or "path/folder/file.txt"
timeout = 30

client = boto3.client('s3')

args = {
  'ClientMethod': 'get_object',
  'Params': { 'Bucket': bucket, 'Key': file_path },
  'ExpiresIn': timeout
}

response = client.generate_presigned_url(**args);
print(response)
