How to Download a File from S3 Using Provided Url

How to generate URL to download file from S3 bucket

See Geoffrey’s answer for the format of the S3 URLs for public access buckets.

To generate a URL that works regardless of whether the bucket/object is public, you can use generate_presigned_url:

s3.generate_presigned_url(
    'get_object',
    Params = {'Bucket': 'copernicus-dem-30m', 'Key': key},
    ExpiresIn = SIGNED_URL_TIMEOUT
)

… with a suitably chosen SIGNED_URL_TIMEOUT (in seconds).

Download a file from S3 using full URI using AWS SDK for Go

Unable to download a file from S3 by the URL in a browser

I made an error in the comments.
Chrome still favours download attribute, but it completely ignores it if the anchor element has cross origin attributes ( meaning, if the file is hosted on a different domain).

To be able to download it, file needs to be served with header: Content-Disposition: attachment;

Check this tutorial to see how to set Content-Disposition in s3 management console: http://iwantmyreal.name/s3-download-only-presigned-upload

AWS S3 File Download from the client-side

If the file you are trying to download is not public then you have to create a signed url to get that file.

The solution is here Javascript to download a file from amazon s3 bucket?
for getting non public files, which revolves around creating a lambda function that will generate a signed url for you then use that url to download the file on button click

BUT if the file you are trying to download you is public then you don't need a signed url, you just need to know the path to the file, the urls are structured like: https://s3.amazonaws.com/ [file path]/[filename]

They is also aws amplify its created and maintain by AWS team.

Just follow Get started and downloading the file from your react app is simply as:

Storage.get('hello.png', {expires: 60})
.then(result => console.log(result))
.catch(err => console.log(err));

How do you download a file from AWS S3 to a client's device?

S3 supports the ability to generate a pre-signed URL via the AWS Javascript API. Users can then GET this URL to download the S3 object to their local device.

See this question for a Node.js code sample.
