asp 擷取url函數小結

方法一：簡單，得不到參數，只有一個虛擬路徑 複製代碼 代碼如下:GetUrl =request("url")

例如：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd
擷取為:shiyan.asp 複製代碼 代碼如下:<%
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：得到整個URL，得到參數 複製代碼 代碼如下:'得到當前頁面的地址
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
擷取為：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd

方法三：得到虛擬路徑，得到參數 複製代碼 代碼如下:Private Function GetUrl()
Dim ScriptAddress,M_ItemUrl,M_item
ScriptAddress = CStr(Request.ServerVariables("SCRIPT_NAME")) '取得當前地址
M_ItemUrl = ""
If (Request.QueryString <> "") Then
ScriptAddress = ScriptAddress & "?"
For Each M_item In Request.QueryString
If M_item = "page_num" Then Exit for '此處的作用就是過濾掉Page_num這個頁次的參數(該參數是在page_turn.asp中自行設定的，根據個人設定而變)，否則每次翻頁都會疊加這個參數，雖然不影響功能，但總歸不太好吧~~
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
擷取為：/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd

方法四：只擷取參數部分字串 複製代碼 代碼如下: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
擷取為：dfsdfsf=dsfsdfd&aa=dddd
