From 96d4bf90120a07faa5163c2e5af542358554dd61 Mon Sep 17 00:00:00 2001 From: Kegan Dougal Date: Wed, 4 Feb 2015 17:07:31 +0000 Subject: [PATCH] Modify API for SimpleHttpClient.get_json and update usages. Previously, this would only return the HTTP body as JSON, and discard other response information (e.g. the HTTP response code). This has now been changed to throw a CodeMessageException on a non-2xx response, with the response code and body, which can then be parsed as JSON.
