用XMLHTTP很好的一个例子

进入www.ting88.com的网站,把歌手专辑页面的URL复制到文本框中再提交就可以得到歌曲的下载路径,如:http://www.ting88.com/MusicList/4141.htm

源程序如下:

<%
on error resume next
dim id,url,getCode,m,i,j,s,d,ns,nd,num,name
id=trim(request.querystring("id"))
'1.获取原网页所有内容
Function getHTTPPage(url)
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 err.Clear
End function

'2.编码转换
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

'得到明码URL
function MyReplace(ConvStr)
ConvStr=replace(ConvStr,"YVI","1")
ConvStr=replace(ConvStr,"ESR","2")
ConvStr=replace(ConvStr,"SXN","3")
ConvStr=replace(ConvStr,"STI","4")
ConvStr=replace(ConvStr,"WFU","5")
ConvStr=replace(ConvStr,"LQU","6")
ConvStr=replace(ConvStr,"QGI","7")
ConvStr=replace(ConvStr,"BLA","8")
ConvStr=replace(ConvStr,"JFU","9")
ConvStr=replace(ConvStr,"LSN","0")
ConvStr=replace(ConvStr,"XPG","/")
ConvStr=replace(ConvStr,"XQD",".")
ConvStr=replace(ConvStr," ","")
ConvStr=replace(ConvStr,"%20","")
ConvStr=replace(ConvStr,"KWD","Wma")
MyReplace=ConvStr
end function
