Rack::ContentLengthChecker

• リクエストのサイズ(Content-Length)を監視、ロギングを行うrackミドルウェアです。

Add this line to your application's Gemfile:

gem 'rack-content_length_checker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-content_length_checker

• Content-Lengthが1.5MB〜2.0 MBの時にlog level warnでログをだし、2.0MB以上の場合log level fatalでログを出す場合の設定
  • rubyのLoggerを使う
  • この設定では、ログを吐くだけ

use Rack::ContentLengthChecker,
  warn: {length: 1_500_000}, # 1.5MB
  fatal: {length: 2_000_000}, # 2.0 MB
  logger: Logger.new(STDOUT)

• エラーを返す場合は、is_errorのオプションを使って下さい
  • 下記例では、Content-Lengthが1.5MB〜2.0 MBの時にlog level warnでログをだし、2.0MB以上の場合log level fatalでログを出し、エラーを返します。
  • エラーの場合は、HTTP Statusは413となります。

use Rack::ContentLengthChecker,
  warn: {length: 1_500_000}, # 1.5MB
  fatal: {length: 2_000_000, is_error: true}, # 2.0 MB
  logger: Logger.new(STDOUT)
