ASP创建日志文件的实例代码
用Asp创 建日志文件这个例子使用文本文件来写入用户的信息创建一个logfile.asp放在每一个asp的页面的顶端<!--#Include File="LogFile.asp"-->当有人来访问你的站点logfile.asp自动把他的信息写入LogFile.txt,如果相关的 URl一样的话则不写入文件
file: LogFile.asp
代码如下:
<%
Dim ValidEntry ' Log variable
' First set that this log is valid
ValidEntry = True
' If Session Variable "LogIn" is not empty
' that mean this person has already been logged
' then set ValidLog to False
If not IsEmpty(Session("LogIn")) then ValidEntry = False
' Here you can add different restriction
' If the refering url is from same site
' don't write to log file
If Left(Request.ServerVariables("HTTP_REFERER"), 17)
=http://jzxue.com Then
ValidEntry = False
End if
If Left(Request.ServerVariables("HTTP_REFERER"), 21)
=http://www.jzxue.com Then
ValidEntry = False
End If
' Now if ValidEntry is True then enter to log file
If ValidEntry Then
Const ForAppending = 8
Const Create = true
Dim FSO
DIM TS
DIM MyFileName
Dim strLog
MyFileName = Server.MapPath("MyLogFile.txt")
Set FSO = Server.CreateObject("Scripting.FileSystemObject")
Set TS = FSO.OpenTextFile(MyFileName, ForAppending, Create)
' Store all required values in strLog

strLog = "<br><P><B>" & now & "</B> "

strLog = strLog & Request.ServerVariables("REMOTE_ADDR") & " "

strLog = strLog & Request.ServerVariables("HTTP_REFERER") & " "

strLog = strLog & Request.ServerVariables("HTTP_USER_AGENT") & "<BR>"

' Write current information to Log Text File.

TS.write strLog

TS.Writeline ""

' Create a session varialbe to check next time for ValidEntry

Session("LogIn") = "yes"

Set TS = Nothing

Set FSO = Nothing

End If
