我是靠谱客的博主个性小蝴蝶，最近开发中收集的这篇文章主要介绍ASP读取Request.QueryString编码的函数代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1. 支持参数纯汉字 ?a=深山老熊
2. 支持参数gb2312 Urlencode编码： ?a=%C9%EE%C9%BD%C0%CF%D0%DC
3. 支持参数UTF-8 Urlencode编码: ?a=%E6%B7%B1%E5%B1%B1%E8%80%81%E7%86%8A

复制代码代码如下:

 
<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%> 
<% 
Option Explicit 
Const YXCMS_CHARSET = "UTF-8" 
Const YXCMS_CODEPAGE = 65001 
Response.CharSet = "UTF-8" 
Session.CodePage = 65001 
'测试URL 
'?n1=深山老熊&n2=%C9%EE%C9%BD%C0%CF%D0%DC&n3=%E6%B7%B1%E5%B1%B1%E8%80%81%E7%86%8A 
'深山老熊 
'GBK : %C9%EE%C9%BD%C0%CF%D0%DC 
'UTF-8 : %E6%B7%B1%E5%B1%B1%E8%80%81%E7%86%8A 
Dim URI,key 
Set URI = new Cls_URI 
'输出所有参数测试 
For Each key In URI.QueryString 
Response.Write "<span style='color:red'>" & key & " : </span>" & URI.Get(key) & "<hr/>" 
Next 
'取单个值
