asp下實現替換遠程檔案為本地檔案並儲存遠程檔案的代碼

1、將下面的文字檔下載,並將.TXT改為remote.asp,裡面有具體設定方法 複製代碼 代碼如下:<%
'添加資源時是否儲存遠程圖片
Const sSaveFileSelect=True

'遠程圖片儲存目錄,結尾請不要加“/”
Const sSaveFilePath="/images/News"

'遠程圖片檔案類型
Const sFileExt="jpg|gif|bmp|png"

'/////////////////////////////////////////////////////
'作 用：替換字串中的遠程檔案為本地檔案並儲存遠程檔案
'參 數：
' sHTML : 要替換的字串
' sSavePath : 儲存檔案的路徑
' sExt : 執行替換的副檔名
Function ReplaceRemoteUrl(sHTML, sSaveFilePath, sFileExt)
Dim s_Content
s_Content = sHTML
If IsObjInstalled("Microsoft.XMLHTTP") = False then
ReplaceRemoteUrl = s_Content
Exit Function
End If

Dim re, RemoteFile, RemoteFileurl,SaveFileName,SaveFileType,arrSaveFileNameS,arrSaveFileName,sSaveFilePaths
Set re = new RegExp
re.IgnoreCase = True
re.Global = True
re.Pattern = "((http|https|ftp|rtsp|mms):(\/\/|\\\\){1}((\w)+[.]){1,}(net|com|cn|org|cc|tv|[0-9]{1,3})(\S*\/)((\S)+[.]{1}(" & sFileExt & ")))"
Set RemoteFile = re.Execute(s_Content)
For Each RemoteFileurl in RemoteFile
SaveFileType = Replace(Replace(RemoteFileurl,"/", "a"), ":", "a")
arrSaveFileName = Right(SaveFileType,12)
sSaveFilePaths=sSaveFilePath & "/"
SaveFileName = sSaveFilePaths & arrSaveFileName
Call SaveRemoteFile(SaveFileName, RemoteFileurl)
s_Content = Replace(s_Content,RemoteFileurl,SaveFileName)
Next
ReplaceRemoteUrl = s_Content
End Function

'////////////////////////////////////////
'作 用：儲存遠端檔案到本地
'參 數：LocalFileName ------ 本地檔案名稱
' RemoteFileUrl ------ 遠程檔案URL
'傳回值：True ----成功
' False ----失敗
Sub SaveRemoteFile(s_LocalFileName,s_RemoteFileUrl)
Dim Ads, Retrieval, GetRemoteData
On Error Resume Next
Set Retrieval = Server.CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "Get", s_RemoteFileUrl, False, "", ""
.Send
GetRemoteData = .ResponseBody
End With
Set Retrieval = Nothing
Set Ads = Server.CreateObject("Adodb.Stream")
With Ads
.Type = 1
.Open
.Write GetRemoteData
.SaveToFile Server.MapPath(s_LocalFileName), 2
.Cancel()
.Close()
End With
Set Ads=nothing
End Sub

'////////////////////////////////////////
'作 用：檢查組件是否已經安裝
'參 數：strClassString ----組件名
'傳回值：True ----已經安裝
' False ----沒有安裝
Function IsObjInstalled(s_ClassString)
On Error Resume Next
IsObjInstalled = False
Err = 0
Dim xTestObj
Set xTestObj = Server.CreateObject(s_ClassString)
If 0 = Err Then IsObjInstalled = True
Set xTestObj = Nothing
Err = 0
End Function
%>

2、調用方法:
<!--#include file="remote.asp"-->

文章入庫的地方改成下面的代碼 複製代碼 代碼如下:If sSaveFileSelect=True Then
Rs("Content")=ReplaceRemoteUrl(ArticleContent,sSaveFilePath,sFileExt)
Else
Rs("Content")=ArticleContent
End If
