asp中xmlhttp组件发包
写的一个小偷函数，注意红色代码部分，其他的自己添加吧！
Function PostHttpPageFrom(HttpUrl,stra,FromUrl)
   Dim Http
Set Http=server.createobject("MSXML2.XMLHTTP")
   Http.open "POST",HttpUrl,False
   Http.setrequestheader "content-length",len(stra)   Http.setrequestheader "content-
type","application/x-www-form-urlencoded"
   Http.setrequestheader "Referer",FromUrl
   Http.send stra 
If Http.Readystate>4 then
      Set Http=Nothing 
GetHttpPage="$False$"
Exit function
End if
PostHttpPageFrom=bytesToBSTR(Http.responseBody,"gb2312")   Set Http=Nothing
If Err.number>0 then
      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.Open1 d)
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = Cset
   BytesToBstr = objstream.ReadText
   objstream.Close
   set objstream = nothing
End Function
