Regex to match S3 file and a directory

Question

I have the following pattern that used to match a S3 URL

Pattern.compile("^s3://([^/]+)/(.*?([^/]+))$");

This matches

s3://bucket/path/key

But does not match a directory

s3://bucket/path/directory/

Is there an easy way to change the pattern to match a directory?

Answer 1

There's only the final slash missing in the regex. You might try this:

^s3://([^/]+)/(.*?([^/]+)/?)$
