XMLHttp ASP远程获取网页内容代码

　　复制代码 代码如下:
url=
wstr=getHTTPPage(url)
start=Newstring(wstr,资源精选<!-- 下载 -->)
over=Newstring(wstr,<div class=friendlink>)
body=mid(wstr,200,500)

response.write body

Function getHTTPPage(url)
dim objXML
set objXML=createobject(MSXML2.XMLHTTP)定义
objXML.open GET,url,false打开
objXML.send()发送
If objXML.readystate<>4 then 判断文档是否已经解析完，以做客户端接受返回消息
exit function
End If
getHTTPPage=bBytesToBstr(objXML.responseBody)返回信息，同时用函数定义编码
set objXML=nothing关闭
if err.number<>0 then err.Clear
End Function

Function Newstring(wstr,strng)
Newstring=Instr(lcase(wstr),lcase(strng))
if Newstring<=0 then Newstring=Len(wstr)
End Function

Function bBytesToBstr(body)
dim objstream
set objstream = CreateObject(adodb.stream)
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = gb2312
转换原来默认的UTF-8编码转换成GB2312编码，否则直接用XMLHTTP调用有中文字符的网页得到的将是乱码
bBytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
end Function

Function BytesToBstr(body)
dim objstream
set objstream = CreateObject(adodb.stream)
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = utf-8
转换原来默认的UTF-8编码转换成GB2312编码，否则直接用XMLHTTP调用有中文字符的网页得到的将是乱码
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
end Function
