Post to /delivery/register_consumer the following payload:
{ "anything": "anything" }
(Flask considers request.json doesn't exist if the payload is empty,
this isn't a problem as we don't have any method accepting empty
payloads, as an API key will be required for register_consumer)
Get the following output to the console:
Client wants the default exchange, unspecified in config. 127.0.0.1 - - [06/Jul/2017 22:09:59] "POST /delivery/register_consumer HTTP/1.1" 400 -
