Rewrite rules

[elliot-nelson]

It might be nice to have some facility to provide rewrite rules in a configuration block. For example, if you have some Rack rewrite (or nginx/unicorn-level rewrites), it's difficult to get a signature match.

As an example, if the incoming request_uri is /api/v1/posts, it'd be nice to be able to say:

ApiAuth.allow_uri('api/v1/posts', ['api/posts', 'posts'])

(The desired outcome is that if I POST to /posts, and nginx rewrites my request to /api/v1/posts, ApiAuth will check each possible signature and return true if any of them match.)

(Another approach might be an option allowing you to specify a certain header -- Http-X-Original-URI, for example, or whatever header your web server might generate -- instead of using request_uri when building and verifying the signature.)

I think it would make sense to have a header that specifies the path
originally used to sign the request. On the server side I wonder if we
should provide for some sort or warning or ability to pass allowed paths
into the authentic? method or some other way to make this an opt in only
feature

Just bumped into the exact same issue, happy to provide a PR if given the direction to fix this.
We have Nginx on top of a Rails application and this is rewriting incoming calls, making the signature check failing.

Worked on a fix for this, you can see it on #137
