Generating a pre-signed URL using the Python SDK

We can create a pre-signed URL using the Python SDK and test it as follows:

1. Create a file named s3presign.py with the following code:

import boto3boto3.setup_default_session(profile_name='awssecadmin')s3_client = boto3.client('s3')url = s3_client.generate_presigned_url('get_object', Params={'Bucket': 'awsseccookbook', 'Key': 'mission-impossible.txt'}, ExpiresIn=300)print(url)

2. Execute the code as python3 s3presign.py:

This will return the pre-signed URL:

Run the URL from a browser (much as we did in the previous section) before and after the specified time.
