Manage Amazon S3 Buckets with Python in minutes — Part 2
Use a familiar programming language like Python to create and access Amazon S3 resources.
Introduction
In part 1 of this series, you can learn how to interact with Amazon S3 buckets using the AWS SDK Python (boto3). We were able to create and list buckets, as well as upload and download files from Amazon S3.
In this post, we will describe how to use Python to grant temporary access to the buckets and objects for users who do not have AWS credentials or permission to access S3 objects via Presigned URLs. Additionally, we will learn to manage bucket policies and bucket CORS configuration using Python.
Presigned URLs
When it comes to Amazon S3, all objects are private by default. The only entity with permission to access these objects is the object owner. However, using their own security credentials, the object owner can share objects with others by creating a presigned URL, and therefore granting time-limited permission to access the objects.
To create a presigned URL for an S3 object, you must provide several details:
- Bucket name
- Object key
- HTTP method (GET to download the object)
- Expiration date and…
