主题：ASP采集中获取网页内所需的html代码

 

有时候,需要获取网页的html代码,如新闻采集。采集之前，首页要得到被采集的页面的html代码，然后根据代码，分析出你想要得到的内容，最后将得到的内容保存到自己的数据库中

function.asp

<% Function getHTTPPage(url) On Error Resume Next dim http set http=Server.createobject("Microsoft.XMLHTTP") Http.open "GET",url,false Http.send() if Http.readystate<>4 then exit function end if getHTTPPage=bytesToBSTR(Http.responseBody,"GB2312") set http=nothing If Err.number<>0 then Response.Write "<p align='center'><font color='red'> <b>服务器获取文件内容出错</b></font></p>" Err.Clear End If  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 %>

index.asp

<!--#include file="function.asp"-->
<%
url="http://www.google.cn"
response.write getHTTPPage(url)
%>
