如何用ASP创建日志文件

你是否有时想知道什么人访问你的站点，什么时间，IP地址等。下面我就这个问题向大家来阐述一下。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

<% 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://devasp.com" Then ValidEntry = False End if If Left(Request.ServerVariables("HTTP_REFERER"), 21)="http://www.devasp.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 = "

" & now & " "
strLog = strLog & Request.ServerVariables("REMOTE_ADDR") & " "
strLog = strLog & Request.ServerVariables("HTTP_REFERER") & " "
strLog = strLog & Request.ServerVariables("HTTP_USER_AGENT") & "
"
“ 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
