echo middleware that print log for a api's request / response
if you write request / response like this,
then get ..
you need only one line to show this request/response log !
e.Use(middleware.CtxLogger())
set formatter as warning level ctxlog
set formatter as CaptionJsonFormatter.Json()
you can also configuration your ctxlog. colorize, json format.. default ctxlog will be formatted as caption_json_formatter.Console(). see more here
you can change the default option, formatter, as you wish.

// [optional] and set 'ANY FORMATTER' compatiable with logrus.formatter
