asp获取远程网页的指定内容的实现代码

代码如下：

<%
'用ASP获取远程目标网页指定内容，代码由广州网站建设http://www.vevb.com提供
On Error Resume Next
Server.ScriptTimeOut=9999999
Function getHTTPPage(Path)
t = GetBody(Path)
getHTTPPage=BytesToBstr(t,"GB2312")
End function
Function Newstring(wstr,strng)
Newstring=Instr(lcase(wstr),lcase(strng))
if Newstring<=0 then Newstring=Len(wstr)
End Function
Function BytesToBstr(body,Cset)
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 = Cset
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function
Function GetBody(url)
on error resume next
Set Retrieval = CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "Get", url, False, "", ""
.Send
GetBody = .ResponseBody
End With
Set Retrieval = Nothing
End Function

'ASP获取远程网页指定内容开始
Dim wstr,str,url,start,over,dtime
a="开始内容" 'ASP获取目标网页内容开始标记
b="结束内容" 'ASP获取网页内容结束标记
url="http://sc.vevb.com/"
wstr=getHTTPPage(url)
start=Newstring(wstr,a)
over=Newstring(wstr,b)
body=mid(wstr,start,over-start)
response.write ""&body&"" '输出获取到的网页内容
'ASP获取远程网页指定内容结束
%>

上面的代码可以获取指定网页的内容，如果是全部获取就更简单了
核心代码:

'ASP获取远程网页指定内容开始
Dim wstr,str,url,start,over,dtime
url="http://sc.vevb.com/"
wstr=getHTTPPage(url)
body=wstr
