关于在rails3中单个页面使用gb2312输出的办法

#coding:utf-8
require 'iconv'
#Conv=Iconv.new('utf-8','gbk')
Conv=Iconv.new("GBK//IGNORE","UTF-8//IGNORE")
#Conv2=Iconv.new("UTF-8//IGNORE","GB18030//IGNORE")
class SdoEdmController < ApplicationController
  before_filter:set_charset
  after_filter { |c| c.response.body = Conv.iconv(c.response.body) }

  def set_charset
    #@headers["Content-Type"] = "text/html; charset=gb2312"
    response.headers["Content-Type"] = "text/html; charset=gb2312"
  end
  def everyday#for mail test
    yyyymmdd=params[:yyyymmdd]
    logger.debug("!!!!!!!!!!!!!!!#$$$$$$$$$$$$$$$$$$$")
    logger.debug(yyyymmdd)
    unless yyyymmdd
      @tuan=Tuan.today
    else
      @tuan=Tuan.day(yyyymmdd)
    end
    @user=User.last
    #@tuan=Tuan.today
    render "tuan_mail/everyday",:layout=>nil
  end
end

这里的思路是在输出前将utf-8的文件代码转换为gb2312,然后在header部分设置gb2312,
同时要在meta部分设置代码为gb2312

        # exists, and the action will be logged for auditing.
  
        # After this action has run, the output will first be localized then
        # compressed to minimize bandwidth usage
      end
  
      private
        def authenticate
          # Implement the filter with full access to both request and response
