用ASP创建日志文件（附源程序）

　　本文标签：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
复制代码 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
dont write to log file
If Left(Request.ServerVariables("HTTP_REFERER"), 17)
="http://jb51.net" Then
ValidEntry = False
End if
If Left(Request.ServerVariables("HTTP_REFERER"), 21)
="http://www.jb51.net" 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
