How to get the URL of a file on AWS S3, return path without AWS Key

I need to use Lambda function ( Python), I need to get S3 path. It should look like this:

s3://some-path-to-the-location-of-generated-text/generated-text.txt

That URL client need to see in browser, without AWS Key, because presigned urls i don't need.

Thank you so much!

You need to use AWS S3 bucket policy which should allow read to all for given file.

Your bucket policy should look like as follows:

 {

  "Statement":[
    {
      "Sid":"PublicRead",
      "Effect":"Allow",
      "Principal": "*",
      "Action":["s3:GetObject"],
      "Resource":["arn:aws:s3:::<name of bucket>/<file that you want everyone can read>"]
    }
}
