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
    '测试URL
    'aspbc.asp?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
    'URI.Get("名称")
