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

Filters for pre and post processing of the response (as methods, procs, and classes)

class WeblogController < ActionController::Base
before_filter :authenticate, :cache, :audit
after_filter { |c| c.response.body = Gzip::compress(c.response.body) }
after_filter LocalizeFilter

def index
# Before this action is run, the user will be authenticated, the cache
# will be examined to see if a valid copy of the results already
# 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
end
end
