asp动态页面防采集的新方法(2)
复制代码 代码如下:
<%
Dim Conn,Rs,Sqlstr,Ip
Set Conn = Server.CreateObject("Adodb.Connection")
Set Rs=Server.Createobject("Adodb.RecordSet")
ConnStr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("Data.mdb")
Conn.Open ConnStr
Ip=Request.ServerVariables("REMOTE_ADDR")
Sqlstr="Select * From [Ip2]"
Rs.Open Sqlstr,Conn,1,3
Application.Lock()
Rs.AddNew()
Rs("Ip2_Address")=Ip
Rs.Update()
Application.UnLock()
Rs.Close
%>
4.Get.asp
复制代码 代码如下:
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<%
Response.Write(Server.HTMLEncode(GetHttpPage("http://localhost/Index.asp","GB2312")))
