Overview

This wraps an HTTP response with a JSON body.

Responses can be configured to use relative URLs for ‘web_url` properties. API endpoints should return absolute URLs so that they make sense outside of the Publishing Platform context. However on internal systems we want to present relative URLs. By specifying a base URI, this will convert all matching web_urls into relative URLs This is useful on non-canonical frontends, such as those in staging environments.

Example:

r = Response.new(response, web_urls_relative_to: "https://www.publishing-platform.co.uk")
r['results'][0]['web_url']
=> "/bank-holidays"
