'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.jb51.net/"
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:
代码如下:
'ASP获取远程网页指定内容开始
Dim wstr,str,url,start,over,dtime
url="http://sc.jb51.net/"
wstr=getHTTPPage(url)
body=wstr
