  • sinatra 中计划任务的问题 at 2015年01月14日

    #3 楼 @ywjno thx! 问题解决了 现在的 rufus-scheduler 创建的时候用.new 取代了.start_new 但是测试还是有点问题... 下面的代码是每秒输出一次 unix 时间。。但输出的结果有时间隔会在 2s

    require 'sinatra'
    require 'rufus/scheduler'
    
    configure do
      scheduler = Rufus::Scheduler.new 
      # test
      scheduler.every '1s' do
        puts Time.now.to_i
      end
    end
    
    get '/' do
      "start work at #{Time.new.strftime('%Y-%m-%d %H:%M:%S')}"
    end
    

    这是输出的结果

    1421213271
    1421213272
    1421213273
    1421213274
    1421213276
    1421213277
    1421213278
    1421213279
    1421213280
    1421213282
    1421213283
    
    

    猜想是因为间隔太短。。可是调到了 5s 以后依然这样

    1421213425
    1421213430
    1421213436
    1421213441
    1421213446
    1421213451
    1421213456
