Ruby 删除Sinatra应用程序中的默认路由日志记录

我有一个带有/health/api端点的Sintra应用程序，如下所述，它每秒被我的负载平衡器调用多次。我只想删除此路由的默认日志记录，或者相反，只将我关心的端点打印到日志中

get '/health/api' do
  # Health Check
  'I keep quiet'
end

get '/members' do
  # get members data
  'This request gets logged'
end

您不能将默认的Rack:：CommonLogger配置为仅打印某些请求，而对其他请求保持安静。但您可以禁用默认的CommonLogger，并使用自己的过滤功能：

require 'rubygems'
require 'rack'
require 'sinatra'

LOGGING_BLACKLIST = ['/health/api']

class FilteredCommonLogger < Rack::CommonLogger
  def call(env)
    if filter_log(env)
      # default CommonLogger behaviour: log and move on
      super
    else
      # pass request to next component without logging
      @app.call(env)
    end
  end

  # return true if request should be logged
  def filter_log(env)
    !LOGGING_BLACKLIST.include?(env['PATH_INFO'])
  end
end

disable :logging
use FilteredCommonLogger

get '/members' do
  # get members data
  'This request gets logged'
end

get '/health/api' do
  # Health Check
  'I keep quiet'
end

需要“rubygems”
需要“机架”
需要“sinatra”
日志记录\u黑名单=['/health/api']
类FilteredCommonLogger

显然，您也可以编写只记录“白名单”请求的自定义记录器。

+1这是定制sinatra标准输出日志的完整解决方案。我做了

p t=env[“PATH\u INFO”]+？？+env[“查询字符串”]；如果t[/^\/log\？/]@app.call env；其他的超级的；结束

但不知何故我仍然看到：
