#6 楼 @luikore 冬天没有虫子了 看来得给它买苹果去..

它潜伏了很久了 昨天才被我发现

#1 楼 @fresh_fish X，被你这么一说好害怕呢

#43 楼 @bhuztez 这个东西自己用不到啊

#13 楼 @doitian 最主要的是 IE10 才正式支持 CORS

#16 楼 @hellojane96 链接呢

#17 楼 @bruceyue 本地可以不预编译，heroku 强制与编译了

#15 楼 @bruceyue development 环境的 asset 相关配置和 production 环境到配置不一样呀

#12 楼 @bruceyue rails guide 里的 asset pipline 部分提到了

#10 楼 @bruceyue 文档

#8 楼 @bruceyue 部署时也可以不合并啊 不是用 Heroku 么？

#11 楼 @bhuztez

5. No authentication or cookies will be sent with the request

In order to prevent misuse of the user’s ambient authority (e.g. cookies, HTTP credentials, client certificates, etc), the request will be stripped of cookies and credentials and will ignore any authentication challenges or Set-Cookie directives in the HTTP response. XDomainRequests will not be sent on previously-authenticated connections, because some Windows authentication protocols  (e.g. NTLM/Kerberos) are per-connection-based rather than per-request-based.

Sites that wish to perform authentication of the user for cross-origin requests can use explicit methods (e.g. tokens in the POST body or URL) to pass this authentication information without risking the user’s ambient authority.

这一点就不太适合吧 ---update-- 没看明白，这东西是在认证的那个请求不发送 cookie 还是所有请求都不能发送？

#5 楼 @bhuztez #9 楼 @knwang http://blogs.msdn.com/b/ie/archive/2012/02/09/cors-for-xhr-in-ie10.aspx 这个是 IE10 才有的。。

#7 楼 @knwang 谢谢推荐。

#6 楼 @lionzixuanyuan 好看吧

#5 楼 @bhuztez 那还不错呢。github 这么用的。他们不支持 ie67

#1 楼 @luikore 即使在 chrome 下，async 属性和普通异步请求也有差异。我前些天测试发现即使加 async 属性的 js 资源还会堵塞 onload 事件

#2 楼 @knwang 这个用起来更复杂了吧 有兼容性限制？

先打印 str_got_at.encoding 然后打印 str_got_at.bytes.to_a.inspect 然后用 DateTime.parse(Iconv.iconv("UTF-8", "GBK", str_got_at))

#22 楼 @stephen 。。。。。。你加上试试 看日志和异常

#4 楼 @bruceyue 那你本地怎么没有 override 呢 heroku 环境可以设置成本地一样，慢慢调吧

中间少个空格吧 应该是2012-12-14 15:05:52

好吧，这样！

class StockspiderWorker
  include Sidekiq::Worker

  def perform
    Stock.all.each do |stock|
      @s = Net::HTTP.get(URI.parse("http://hq.sinajs.cn/list=" + stock[:market] + stock[:code]))
      @s = @s[@s.index("\"")+1, @s.rindex("\"")-1]
      @records = @s.split(",")
      str_got_at = "#{@records[30]}#{@records[31]}"
      Rails.logger.info(str_got_at)
      Rails.logger.info "*" * 100
      got_at = DateTime.parse(str_got_at)

      stock.update_attributes(:name => Iconv.iconv("UTF-8", "GBK", @records[0]).first.to_s, 
        :volume => @records[8], :obv => @records[9], 
        :op => @records[1], :ycp => @records[2], 
        :cp => @records[3], :tp => @records[4], 
        :lp => @records[5], 
        :got_at => got_at)
    end
  end
end

#34 楼 @bhuztez 找到 speaker deck 用的那个 gem 了：https://github.com/jonmagic/grim 可以从 pdf 获取文字和抽取成图片。

class StockspiderWorker
  include Sidekiq::Worker

  def perform
    Stock.all.each do |stock|
      @s = Net::HTTP.get(URI.parse("http://hq.sinajs.cn/list=" + stock[:market] + stock[:code]))
      @s = @s[@s.index("\"")+1, @s.rindex("\"")-1]
      @records = @s.split(",")
      got_at = DateTime.parse("#{@records[30]}#{@records[31]}")
      Rails.logger.info(got_at)
      Rails.logger.info "*" * 100
      stock.update_attributes(:name => Iconv.iconv("UTF-8", "GBK", @records[0]).first.to_s, 
        :volume => @records[8], :obv => @records[9], 
        :op => @records[1], :ycp => @records[2], 
        :cp => @records[3], :tp => @records[4], 
        :lp => @records[5], 
        :got_at => got_at)
    end
  end
end

这样试试，看看日志输出

你 worker 里到代码是怎么写的？ /Users/stephen/Gupiao/app/workers/stockspider_worker.rb:17 这里出错那个方法

#34 楼 @bhuztez 不记得了

1.9.3p327 :010 > DateTime.parse(" ")
ArgumentError: invalid date
    from (irb):10:in `parse'
    from (irb):10
    from /home/hooopo/.rvm/rubies/ruby-1.9.3-p327/bin/irb:16:in `<main>'
1.9.3p327 :011 > Time.parse " "

    from /home/hooopo/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/1.9.1/time.rb:267:in `parse'

    from /home/hooopo/.rvm/rubies/ruby-1.9.3-p327/bin/irb:16:in `<main>'
1.9.3p327 :012 > 

根据你的错误信息，你这两个错误都是因为传的是空字符串导致的。

#31 楼 @bhuztez 好多这种转换的项目都是中国人搞得。。

直接用Time.parse
