asp 获取url函数小结，需要的朋友可以参考下。方法一：简单，得不到参数，只有一个虚拟路径
复制代码代码如下:
GetUrl =request(url)
例如：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
获取为:shiyan.asp
复制代码代码如下:
<%
dim changdu,url,ends,wurl
changdu=len(request.ServerVariables(URL))
url=instrrev(request.ServerVariables(URL),/)
url=url+1
ends=changdu+1-url
wurl=mid(request.ServerVariables(URL),url,ends)
%>
方法二：得到整个URL，得到参数
复制代码代码如下:
'得到当前页面的地址
Function GetUrl()
On Error Resume Next
Dim strTemp
If LCase(Request.ServerVariables(HTTPS)) = off Then
strTemp = http://
Else
strTemp = https://
End If
strTemp = strTemp & Request.ServerVariables(SERVER_NAME)
If Request.ServerVariables(SERVER_PORT) <> 80 Then strTemp = strTemp & : & Request.ServerVariables(SERVER_PORT)
strTemp = strTemp & Request.ServerVariables(URL)
If Trim(Request.QueryString) <> Then strTemp = strTemp & ? & Trim(Request.QueryString)
GetUrl = strTemp
End Function
例如：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
获取为：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
方法三：得到虚拟路径，得到参数
复制代码代码如下:
Private Function GetUrl()
Dim ScriptAddress,M_ItemUrl,M_item
ScriptAddress = CStr(Request.ServerVariables(SCRIPT_NAME)) '取得当前地址
M_ItemUrl =
If (Request.QueryString <> ) Then
ScriptAddress = ScriptAddress & ?
For Each M_item In Request.QueryString
If M_item = page_num Then Exit for '此处的作用就是过滤掉Page_num这个页次的参数(该参数是在page_turn.asp中自行设置的，根据个人设定而变)，否则每次翻页都会叠加这个参数，虽然不影响功能，但总归不太好吧~~
If InStr(page,M_Item)=0 Then
M_ItemUrl = M_ItemUrl & M_Item &=& Server.URLEncode(Request.QueryString(&M_Item&))
else
M_ItemUrl = M_ItemUrl & M_Item &=& Server.URLEncode(Request.QueryString(&M_Item&)) & &
End If
Next
Else
ScriptAddress = ScriptAddress & ?
end if
GetUrl = ScriptAddress & M_ItemUrl
End Function
例如：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
获取为：/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
方法四：只获取参数部分字符串
复制代码代码如下:
Function GetUrl()
On Error Resume Next
Dim strTemp
If LCase(Request.ServerVariables(HTTPS)) = off Then
strTemp = http://
Else
strTemp = https://
End If
strTemp = strTemp & Request.ServerVariables(SERVER_NAME)
If Request.ServerVariables(SERVER_PORT) <> 80 Then strTemp = strTemp & : & Request.ServerVariables(SERVER_PORT)
strTemp = strTemp & Request.ServerVariables(URL)
If Trim(Request.QueryString) <> Then strTemp = strTemp & ? & Trim(Request.QueryString)
GetUrl = strTemp
geturl=mid(geturl,instr(geturl,?)+1)
End Function
例如：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
获取为：dfsdfsf=dsfsdfd&aa=dddd
