How to get the original request URI in api gateway?

Question

From a lambda implemented api gateway resource, how to get the original request URI. Or even just the original path?

Lacking a better way I'm currently using the following three variables that I pass down to the lambda using the default request template:

$context.resourcePath   contains the path with variable names   ex: "/blah/{var}"
$input.params().path    contains the variable names and values  ex: {"var":"something"}
$context.stage          contains the stage                      ex: "prod"

That's quite a hassle since it requires path variable substitution to get the original call path:

/prod/blah/something

How can I get the original URL or URI?

I'm not finding anything in the documentation that lets you get the original call URI. I can add a feature request to consider adding it. Can you describe your use case. Why do you want to get the original URI?
