RailsMiddlewareLog

Print Log for request when every middleware start in Rails. You can set which request to log, and the content you want to print.

在Rails的每个middleware开始的时候打印日志，可以配置那些请求，以及自定义打印内容。

Add this line to your application's Gemfile:

gem 'rails_middleware_log'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_middleware_log
