asp获取URL的方法

方法一：简单，得不到参数，只有一个虚拟路径

GetUrl =request("url")

方法二：得到整个URL，得到参数

'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

方法二：得到虚拟路径，得到参数

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
