asp獲取遠程網(wǎng)頁(yè)的指定內容的實(shí)現代碼

核心函數代碼如下：

<% 
'用ASP獲取遠程目標網(wǎng)頁(yè)指定內容，代碼由廣州網(wǎng)站建設//www.jb51.net提供 
On Error Resume Next 
Server.ScriptTimeOut=9999999 
Function getHTTPPage(Path) 
t = GetBody(Path) 
getHTTPPage=BytesToBstr(t,"GB2312") 
End function 
Function Newstring(wstr,strng) 
Newstring=Instr(lcase(wstr),lcase(strng)) 
if Newstring<=0 then Newstring=Len(wstr) 
End Function 
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 
Function GetBody(url) 
on error resume next 
Set Retrieval = CreateObject("Microsoft.XMLHTTP") 
With Retrieval 
.Open "Get", url, False, "", "" 
.Send 
GetBody = .ResponseBody 
End With 
Set Retrieval = Nothing 
End Function 

'ASP獲取遠程網(wǎng)頁(yè)指定內容開(kāi)始 
Dim wstr,str,url,start,over,dtime 
a="開(kāi)始內容" 'ASP獲取目標網(wǎng)頁(yè)內容開(kāi)始標記 
b="結束內容" 'ASP獲取網(wǎng)頁(yè)內容結束標記 
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&"" '輸出獲取到的網(wǎng)頁(yè)內容 
'ASP獲取遠程網(wǎng)頁(yè)指定內容結束 
%> 

上面的代碼可以獲取指定網(wǎng)頁(yè)的內容，如果是全部獲取就更簡(jiǎn)單了

代碼如下:

'ASP獲取遠程網(wǎng)頁(yè)指定內容開(kāi)始 
Dim wstr,str,url,start,over,dtime 
url="http://sc.jb51.net/" 
wstr=getHTTPPage(url) 
body=wstr

如果想將代碼保存到本地

Dim wstr,str,url,start,over,dtime
url="https://www.jb51.net/"
wstr=getHTTPPage(url)
filename="index.htm"
if wstr<>"" and request("action")="makeindex" then
body=wstr
Set fso = Server.CreateObject("Scripting.FileSystemObject")
Set fout = fso.CreateTextFile(server.mappath(""&filename&""))
fout.Write body
fout.close
set fout=nothing
set fso=nothing
If Err.number=0 then
response.write("<div class=""tishi"">首頁(yè)生成成功??！</div>")
end if
end if

具體的大家可以根據需要自行修改即可。
