禁用IP地址日志

Question

我试图在处理请求时禁用IP地址的记录。但我找不到这样做的方法。我想禁用IP日志的有限部分，我的应用程序，其中用户尚未认证。

所以我的问题是

如何在rails日志中禁用特定页面的IP记录(因此IP将不会保存在任何日志中)

我使用Rails 3.2.17

编辑:

下面是示例日志(来自environment.log)

Started GET "/my_path" for 192.168.0.109 at 2014-03-28 11:53:20 +0530

我不想保存192.168.0.109在日志文件

Answer 1

在config/initializers中添加log_format文件。rb:

class ActiveSupport::BufferedLogger
  def formatter=(formatter)
    @log.formatter = formatter
  end
end
class Formatter
  SEVERITY_TO_TAG_MAP     = {'DEBUG'=>'meh', 'INFO'=>'fyi', 'WARN'=>'hmm', 'ERROR'=>'wtf', 'FATAL'=>'omg', 'UNKNOWN'=>'???'}
  SEVERITY_TO_COLOR_MAP   = {'DEBUG'=>'0;37', 'INFO'=>'32', 'WARN'=>'33', 'ERROR'=>'31', 'FATAL'=>'31', 'UNKNOWN'=>'37'}
  USE_HUMOROUS_SEVERITIES = true
  def call(severity, time, progname, msg)
    if USE_HUMOROUS_SEVERITIES
      formatted_severity = sprintf("%-3s","#{SEVERITY_TO_TAG_MAP[severity]}")
    else
      formatted_severity = sprintf("%-5s","#{severity}")
    end
    formatted_time = time.strftime("%Y-%m-%d %H:%M:%S.") << time.usec.to_s[0..2].rjust(3)
    color = SEVERITY_TO_COLOR_MAP[severity]
    "33[0;37m#{formatted_time}33[0m [33[#{color}m#{formatted_severity}33[0m] #{msg.strip} (pid:#{$$})n"
  end
end
Rails.logger.formatter = Formatter.new

解决方案

  # Overriding Rails logger to not save IP addresses for specific paths
  # Put this file in <app_root>/config/initializers
  # defining setter for Rails default log formatter, so later we can set our custom logger using '='
  class ActiveSupport::BufferedLogger
    def formatter=(formatter)
      @log.formatter = formatter
    end
  end
  # Modified Formatter Class with custom 'call' method
  class Formatter
    Format = "%sn"
    # Remove IP while getting request on below specified Path
    FilteredActionRegexp = /app_path|another_path/i
    # reference for regexp of IP address
    # http://answers.oreilly.com/topic/318-how-to-match-ipv4-addresses-with-regular-expressions/
    IPRegexp = /b(?:[0-9]{1,3}.){3}[0-9]{1,3}b/
    FilteredString = '**FILTERED**'
    def call(severity, time, progname, msg)
      Format % [msg2str(filter_ip(msg))]
    end
    private
    def msg2str(msg)
      case msg
      when ::String
        msg
      when ::Exception
        "#{ msg.message } (#{ msg.class })n" <<
          (msg.backtrace || []).join("n")
      else
        msg.inspect
      end
    end
    # Replace IP Address with custom string if action is filtered
    def filter_ip(msg)
      # Replace only if message contains filtered action
      if msg =~ FilteredActionRegexp
        # If log string contains IP address then remove it with custom string
        msg.gsub(IPRegexp, FilteredString )
      else
        msg
      end
    end
  end
  # Override Rails default logger formatter
  Rails.logger.formatter = Formatter.new

我使用logage

驯服Rails的默认请求日志

而不是像这样有大量不可解析的日志输出:

Started GET "/" for 127.0.0.1 at 2012-03-10 14:28:14 +0100
Processing by HomeController#index as HTML
  Rendered text template within layouts/application (0.0ms)
  Rendered layouts/_assets.html.erb (2.0ms)
  Rendered layouts/_top.html.erb (2.6ms)
  Rendered layouts/_about.html.erb (0.3ms)
  Rendered layouts/_google_analytics.html.erb (0.4ms)
Completed 200 OK in 79ms (Views: 78.8ms | ActiveRecord: 0.0ms)

你得到一行所有重要的信息，像这样:

method=GET path=/jobs/833552.json format=json controller=jobs action=show status=200 duration=58.33 view=40.43 db=15.26
