asp 获取url函数小结

GetUrl =request("url") 
 
例如：http://127.0.0.1/shiyan.asp?dfsdfsf=dsfsdfd&aa=dddd 
获取为:shiyan.asp 
 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 
 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 
 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 
 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
