ASP读取地址栏传递过来的参数的方法

asp网页地址栏传过来的参数有许多种，如数字，英文，汉字等；不同的页面编码，传递汉字的方法也不一样。这里有一个Request.QueryString读取编码的函数代码，与大家共享一下。
1. 支持参数纯汉字 aspbc.asp?a=深山老熊
2. 支持参数gb2312 Urlencode编码： aspbc.asp?a=%C9%EE%C9%BD%C0%CF%D0%DC
3. 支持参数UTF-8 Urlencode编码: aspbc.asp?a=%E6%B7%B1%E5%B1%B1%E8%80%81%E7%86%8A
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

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
