小编Leo*_*eoh的帖子

我是红宝石的新手,我希望得到每月最后一个星期五的那一天.例如,3月的最后一个星期五是29,即4月26日的最后一个星期五.那么,我该如何获得解决方案呢？我正在使用rails框架.

该方法.cweek返回一年中的一周,但不返回当月的一周.

我想从(ruby on rails)响应中删除一些标题

标题响应:

• HTTP/1.1 200好的
• 日期:星期四,2013年6月6日14:42:26 GMT
• 连接:保持活力
• X-Runtime:0.01900
• 内容类型:text/plain; 字符集= utf-8的
• Cache-Control:private,max-age = 0,必须重新验证
• 服务器:WEBrick/1.3.1(Ruby/1.8.7/2012-10-12)
• 内容长度:281
• Etag:"71078380e2824af40330c40e73fb9869",

我想删除或更改的标题是:

• 连接:Keep-Alive(更改为关闭)
• X-Runtime:0.01900(删除此项)
• Cache-Control:private,max-age = 0,必须重新验证(删除此)
• 服务器:WEBrick/1.3.1(Ruby/1.8.7/2012-10-12)(删除此)
