Load/ Access all images of a folder from AWS S3 Python

Question

I want to load, access to manipulate with all images in a folder hosted on AWS S3. At local, i use path='foldername'. In AWS, i used this:

import boto3
s3 = boto3.client('s3', aws_access_key_id='XXXX', aws_secret_access_key= 'XXXX', region_name='xxx')
obj = s3.get_object(Bucket='xxx', Key='foldername/')
path= obj.load()

But it's cause an error:

botocore.errorfactory.NoSuchKey: An error occurred (NoSuchKey) when calling the GetObject operation: The specified key does not exist.

Answer 1

It appears that you want the images to appear on a web page, while keeping them secure.

You can do this by using <img src=...> tags, with the URL generated as an Amazon S3 pre-signed URL , which is a time-limited URL that provides temporary access to a private object.

However, your back-end code would need to know the name of each object to generate the pre-signed URL and the <img> tags in the HTML. To do that, the back-end code should call list_objects_v2() to obtain a list of Keys (filenames). The code can then loop through the results and generate the <img> tags.
