Question

每天，我的Rails 2.3.16网络应用程序会检查许多外部网站上的数据，以确定这些网站上的链接是否仍然有效或是否为404.我每天收到很多电子邮件，我想要更改此流程运行的频率，以便我不会经常收到尽可能多的电子邮件。

有一个文件domain_checker.rb，它位于\ web \ current \ lib \ daemons中。但是，我无法在文件中看到任何关于守护程序何时运行的内容。它似乎每天早上06:55:00 +0000运行。有没有办法改变频率？我应该从哪里开始看？对不起，我在Rails非常业余，并且正在摸索着。

以下是domain_checker.rb文件中的已清理代码，以供参考。编辑：我添加了代码，我认为ActiveMailer正在发送这些电子邮件。

#!/usr/bin/env ruby

#You might want to change this
ENV["RAILS_ENV"] ||= "production"

require File.dirname(__FILE__) + "/../../config/environment"
require 'net/http'
require 'uri'
# require "system_timer"


class Net::HTTP
  alias_method :old_initialize, :initialize
  def initialize(*args)
    old_initialize(*args)
    @ssl_context = OpenSSL::SSL::SSLContext.new
    @ssl_context.verify_mode = OpenSSL::SSL::VERIFY_NONE
  end
end

def get_url(uri_str,keywords, limit=10)
  raise ArgumentError, 'HTTP redirect too deep' if limit == 0

  url = URI.parse(uri_str)

  http.read_timeout = 10
  http.open_timeout = 10
  response = nil

  begin
  SANITIZED 
  end
  SANITIZED
  if keywords == nil or keywords == ""
    case response.code
    when /^2|3\d{2}/ then true
      #when Net::HTTPSuccess     then true
      #when Net::HTTPRedirection then true
      #when Net::HTTPFound       then true
      #when Net::HTTPRedirection then get_url(response['location'], limit - 1) 
    else
      response.error!
    end
  else
    if response.code =~ /^2|3\d{2}/ and response.body.include? keywords 
      true
      #when Net::HTTPSuccess     then true
      #when Net::HTTPRedirection then true
      #when Net::HTTPFound       then true
    elsif response.code == Net::HTTPRedirection then get_url(response['location'], limit - 1) 
    else
      @response_pass = nil
      response.error!
    end
  end
rescue Timeout::Error
  return false, "Timeout"
rescue TimeoutError
  return false, "Timeout"
rescue Exception
  if response != nil
    if not @response_pass =~ /^2|3\d{2}/  #check for errant 200/300s and get rid of them...
      return false, @response_pass, response['location'], response.body  #return response error code if it isn't 2xx-3xx
    else
      return false, nil
    end
  else
    return false, nil
  end
end


@lists = List.find(:all)
for list in @lists
  SANTIZED
if (@result == false) then
  # ActiveRecord::Base.logger.info("#{task.list.id}, #{task.list.name}, #{code}, #{url}.\n")  
  UserMailer.deliver_emaildown(task, "Business Website", code, url)
end
  end

  ActiveRecord::Base.logger.info("The site checker is still running at #{Time.now}.\n")

end

ActiveRecord::Base.logger.info("The site checker is done at #{Time.now}.\n")

此代码不处理调度。调度通常委托给gem或cron之类的东西。
