Problem

It would be nice to be able to specify AWS profile via query string, like ?profile=my_profile.

At the moment the only possible way to do it is via an env var AWS_PROFILE (or AWS_DEFAULT_PROFILE), which is very inconvenient and doesn't work well if you have multiple AWS accounts and multiple projects.

Solution

It won't require any SDK updates, just a couple of code changes.
As per the doc, it will need Profile: xxx here.

The profile can be parsed in here with renaming the ConfigFromURLParams function to something more appropriate like SessionFromURLParams .

I'd be keen to make a PR if the idea sounds good.
