做ASP小偷时.经常需要用到的函数_

采集页面:
Function GetPage(url)
dim SendData,Retrieval
Set Retrieval = CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "post", url, False
.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
.setRequestHeader "User-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)"
.Send()
GetPage = BytesToBstr(.ResponseBody)
End With
Set Retrieval = Nothing
End Function
转换乱码:
Function BytesToBstr(body)
dim objstream
set objstream = Server.CreateObject("adodb.stream")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = "GB2312"
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function
获取指定的内容
Function GetContent(str,start,last,n)
If Instr(lcase(str),lcase(start))>0 then
select case n
case 0 ’左右都截取（都取前面）（去处关键字）
GetContent=Right(str,Len(str)-Instr(lcase(str),lcase(start))-Len(start)+1)
GetContent=Left(GetContent,Instr(lcase(GetContent),lcase(last))-1)
case 1 ’左右都截取（都取前面）（保留关键字）
GetContent=Right(str,Len(str)-Instr(lcase(str),lcase(start))+1)
GetContent=Left(GetContent,Instr(lcase(GetContent),lcase(last))+Len(last)-1)
case 2 ’只往右截取（取前面的）（去除关键字）
GetContent=Right(str,Len(str)-Instr(lcase(str),lcase(start))-Len(start)+1)
end select
Else
GetC
End if
end function

删除HTML标签:
function DelHtml(htmlCode)
dim iStart,iEnd
dim sTemp
sTemp=htmlCode
iStart=instr(sTemp,"<")
iEnd=instr(sTemp,">")
do while iStart>0 and iEnd>0 and iEnd-iStart>0
sTemp=replace(sTemp,mid(sTemp,iStart,iEnd-iStart+1),"")
iStart=instr(sTemp,"<")
iEnd=instr(sTemp,">")
loop
DelHtml=sTemp
end function
