'常用函數(shù)
'1、輸入url目標(biāo)網(wǎng)頁地址，返回值getHTTPPage是目標(biāo)網(wǎng)頁的html代碼
function getHTTPPage(url)
dim Http
set Http=server.createobject("MSXML2.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、轉(zhuǎn)換亂瑪，直接用xmlhttp調(diào)用有中文字符的網(wǎng)頁得到的將是亂瑪，可以通過adodb.stream組件進(jìn)行轉(zhuǎn)換
Function BytesToBstr(body)
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 = "GB2312" '轉(zhuǎn)換原來默認(rèn)的UTF-8編碼轉(zhuǎn)換成GB2312編碼，否則直接用XMLHTTP組件調(diào)用有中文字符的網(wǎng)頁得到的將是亂碼
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function
'下面試著調(diào)用http://www.google的html內(nèi)容
Dim Url,Html
Url="http://www.google";
Html = getHTTPPage(Url)
Response.write Html
